Definitions

  • the invention relates to a mobile antenna system with a telescopic mast, which is arranged foldable on a base frame with a base area corresponding to that of a container, the base frame having laterally fold-out cantilevers which are provided at their outer ends with support cylinders and base plates which are supported on the base .
  • Such antenna systems have mobile carriers, mostly trucks. They can be set up with these or separately. Because of their height, their telescopic masts have to be supported laterally and anchored, for which purpose they are assigned pivotable brackets which are designed as telescopic support legs according to DE-OS 32 01 067. These known antenna systems can only carry small weights, especially in the area of the top of the mast, and are therefore of limited use. In addition, the telescopic design of the support legs means that there is a high manufacturing outlay and thus correspondingly high investment costs. The same applies in principle to the antenna mast known from DE-OS 17 59 192.3-25, which is supported accordingly via a trestle of support legs and, in addition, via a support reaching down to the ground in order to achieve greater stability. Here too, as mentioned, only limited loads can be attached to the mast.
  • Antenna systems are also known from the prospectus of the applicant W 477 f / sp. 285,500 H. According to Figs. 9738 and 44328, they have laterally pivotable booms that have vertical support cylinders at the ends, against which the booms can be braced on the ground. Movable operating bars are attached to the chassis of the carrier vehicle or to the base frame of the mast.
  • the disadvantage of this known system is that it is a must have certain ground clearance because the cantilevers are designed as sloping beams or structures on which the vertical support cylinders are arranged at the ends. This means that such a system cannot be moved in the manner of a container by such carrier vehicles, but rather must be tailored to such a vehicle in order to ensure the necessary ground clearance in any case. Partial dismantling is even necessary for transport by rail or ship.
  • Another antenna system with a telescopic mast that can be supported by side arms can be found in the same brochure (51243, 51238).
  • This system has a base frame on which the swing-out booms are articulated via an inclined axis.
  • the arms which have the extendable support feet at the ends up to the height of the base frame, so that overall favorable dimensions result.
  • the known antenna system is only intended for relatively light units and is equipped with support feet and brackets which can be extended by hand. With larger systems, the boom ends would protrude very far or could not be folded in unhindered. In both systems, the mast is not braced, which means that e.g. Enable directional antennas.
  • a stiff four-link system is known, but used there as a support device for excavators and cranes.
  • This four-bar system cannot be equated with articulated struts, especially since it is much more complex to build and does not save sufficient space even when it is closed.
  • a support bracket for construction machinery is known from DE-GM 76 39 621, in which a type of support cylinder can be pivoted from the vertical into the boom itself.
  • the boom is designed as a telescopic beam and the support cylinder itself can be pivoted about an articulation, so that overall a relatively complex, but not seen from the support cylinder, stable design results which requires a complex telescopic boom.
  • Both known systems have a very small and therefore unsatisfactory projection for antenna systems.
  • the invention has for its object to provide an antenna system with container-like dimensions, which is inexpensive to transport, easy to set up and dismantle and has great stability thanks to wide cantilever arms, which are designed so that the antenna system even in extremely uneven terrain is to be set up.
  • the front and rear booms are designed as a two-part structure
  • the outer section, which supports the support cylinder can be pivoted via a horizontally arranged joint relative to the inner section connected to the base frame and has a rope pulley via which a tension cable which can be actuated by a cable winch assigned to the supporting structure is guided to the mast head
  • both sections of the front and rear brackets are each connected as a whole to the base frame via an articulated strut, each of the articulated struts being able to be folded in and out again via an associated hydraulic cylinder.
  • Such an antenna system can therefore be transported in a container-like manner because the laterally extendable or swing-out booms can be folded up and raised from a stable lattice structure, for example, in such a way that they can be arranged above the base frame or above the loading area of the carrier vehicle even when retracted.
  • the laterally extendable or swing-out booms can be folded up and raised from a stable lattice structure, for example, in such a way that they can be arranged above the base frame or above the loading area of the carrier vehicle even when retracted.
  • the tensioning cable since it is guided on the foldable section of the jib via a cable pulley and thus causes this section to swivel in.
  • the boom itself is hydraulically swung in and out using a kink strut.
  • Such an antenna system apart from the extension of the mast, can itself be installed in a very short time so that a correspondingly high mast can then be extended without the risk that it is endangered by the wind or other loads and above all, that it can be safely used for directional radio operations due to the guying.
  • the antenna system according to the application thus has pivotable cantilevers which can be pivoted so high and so that the entire retracted system can be easily transported or transported on a carrier vehicle in terms of containers.
  • these brackets enable a secure stand even when the floor is extremely uneven and the antenna is aligned securely.
  • the front and rear arms connected to the base frame are associated with control bars which have links with which the control bars can be pivoted with respect to the base frame.
  • the articulated struts and / or in each case the section of the boom are expediently connected to the pivotable operating webs or the links which guide them via coupling rods. It is thus advantageously possible to fold down the operating webs that are important for assembly and disassembly at the same time as the booms are swung out, or to pull them out in the case of another design, which can then be used by the operating personnel during the further extension and stabilization of the booms.
  • operating bars are used primarily to actuate the waveguide drums, the push rod locks, the antenna assembly and also in emergency operation they are required. Overall, it is possible in this way to provide a relatively simple system of operating bars on the sides of the carrier vehicle, especially since the operating bars can be designed as such in an aluminum hollow profile construction. Since they can be swiveled out simply and securely and can also be swiveled in again when the booms are retracted, they can perform further functions, the invention providing for this purpose that they serve to protect the attachments, in particular the waveguide, during transport.
  • a particularly expedient embodiment of the invention provides that the section of the front and rear brackets supporting the support cylinder is formed to form a grid triangle consisting of a base strut and support struts, on the base strut of which the support cylinder is attached and in the node formed by the support struts the horizontally arranged joint and the rope pulley is arranged at the junction point opposite the jib foot.
  • the hinge is attached so that the folding of the section supporting the support cylinder is also ensured due to its own weight, for which purpose it is provided, as explained, at the corresponding node, namely at the node of the lattice triangle formed by the support struts.
  • the section supporting the support cylinder must be fixable relative to the section pivotably attached to the base frame.
  • This bar is pulled out when the grid triangle is folded down and can then be locked in the end position so that the necessary supporting forces can be transferred without problems.
  • the bar is advantageously locked in that the segment connected to the base frame is assigned a segment lock which can be pivoted via a spindle in front of the beam, the bar having interlocking bolts and hooks at the free end and the segment in the locked state.
  • An embodiment of the invention which is advantageous for protecting the rope as such provides that the rope winch assigned to the base frame is designed as a hydraulically driven friction winch. Since the ropes perform an extremely important function due to the forces to be taken over by them, they are secured accordingly, especially by applying an appropriate coating. This coating is retained because the friction winch works gently.
  • the guy rope pretensioning force of all friction winches is jointly monitored and hydraulically controlled. During operation of the mast or the associated antenna system, care is taken to ensure that the guy ropes are each subjected to a uniform tightening force or pretensioning force. Since all four friction winches are connected at the same time and apply the same pressure, a uniform protection of the mast is guaranteed without additional measures being necessary.
  • the folding of the section supporting the support cylinder which is designed according to the invention as a lattice triangle, is achieved solely by the dead weight, whereby the dead weight can be increased even further by providing consoles for the octagonal or round-shaped base plates on the side of the support cylinder, the base plates being above
  • This also gives you the option of detaching the base plates from the brackets after unfolding the lattice triangle and then quickly connecting them to the support cylinder using the quick-release fasteners, in order to ensure even support even on uneven floors.
  • the invention is characterized in particular by the fact that an antenna system with a supporting mast and base frame that is advantageously transportable is created, which can be applied to the chassis or the loading area of the carrier vehicle without difficulty, because the outriggers assigned to the base frame can be folded to container dimensions.
  • the outriggers important for supporting the mast are folded in so that they do not represent any hindrance during transport. When they are folded in, they are operated by the guy rope and brought into the transport position without the need for additional intervention by the operating teams. At the same time, the operating bridges are also folded in, which can then also be optimally used to secure the machine parts behind them. Conversely, the booms are swung out via the hydraulic cylinders assigned to the articulated struts.
  • the swung-in section of the jib also swings out at the same time, so that it can then be locked in the swung-out position via the beam.
  • the support cylinder assigned to each boom is extended in order to secure the entire system at the same time.

Description

Die Erfindung betrifft eine mobile Antennenanlage mit einem teleskopierbaren Mast, der auf einem Grundrahmen mit einer Grundfläche entsprechend der eines Containers klappbar angeordnet ist, wobei der Grundrahmen seitlich ausklappbare Ausleger aufweist, die an ihren äußeren Enden mit Stützzylindern und sich auf dem Untergrund abstützenden Bodenplatten versehen sind.The invention relates to a mobile antenna system with a telescopic mast, which is arranged foldable on a base frame with a base area corresponding to that of a container, the base frame having laterally fold-out cantilevers which are provided at their outer ends with support cylinders and base plates which are supported on the base .

Derartige Antennenanlagen verfügen über mobile Träger, meist Lastkraftwagen. Sie können mit diesen oder getrennt davon aufgestellt werden. Aufgrund ihrer Höhe müssen deren teleskopierbare Tragmasten seitlich abgestützt und abgespannt werden, wozu ihnen schwenkbare Ausleger zugeordnet sind, die gemäß DE-OS 32 01 067 als teleskopierbare Stützbeine ausgebildet sind. Diese bekannten Antennenanlagen können nur geringe Gewichte, insbesondere im Bereich der Spitze des Tragmastes tragen und sind damit nur begrenzt einsetzbar. Darüber hinaus ist durch die teleskopierbare Ausbildung der Stützbeine ein hoher Fertigungsaufwand gegeben und damit auch entsprechend hohe Investitionskosten. Das gleiche gilt im Prinzip für den aus der DE-OS 17 59 192.3-25 bekannten Antennenmast, wobei dieser zur Erzielung einer höheren Stabilität sich über einen Bock aus Stützbeinen und darüber hinaus über eine bis zum Untergrund reichende Stütze entsprechend abstützt. Auch hier können, wie erwähnt, nur begrenzte Lasten am Tragmast angebracht werden.Such antenna systems have mobile carriers, mostly trucks. They can be set up with these or separately. Because of their height, their telescopic masts have to be supported laterally and anchored, for which purpose they are assigned pivotable brackets which are designed as telescopic support legs according to DE-OS 32 01 067. These known antenna systems can only carry small weights, especially in the area of the top of the mast, and are therefore of limited use. In addition, the telescopic design of the support legs means that there is a high manufacturing outlay and thus correspondingly high investment costs. The same applies in principle to the antenna mast known from DE-OS 17 59 192.3-25, which is supported accordingly via a trestle of support legs and, in addition, via a support reaching down to the ground in order to achieve greater stability. Here too, as mentioned, only limited loads can be attached to the mast.

Aus dem Prospekt der Anmelderin W 477 f/sp.285.500 H sind ebenfalls Antennenanlagen bekannt. Sie verfügen gemäß Abb. 9738 und 44328 über seitlich verschwenkbare Ausleger, die endseitig senkrechtstehende Abstützzylinder aufweisen, gegen die sich die Ausleger am Boden abspannen können. Am Chassis des Trägerfahrzeuges bzw. am Grundrahmen des Tragmastes sind verschiebbare Bedienungsstege angebracht. Nachteilig bei dieser bekannten Anlage ist, daß sie eine bestimmte Bodenfreiheit haben muß, weil die Ausleger als schräg nach unten verlaufende Balken oder Tragwerke ausgebildet sind, an denen endseitig die senkrechtstehenden Abstützzylinder angeordnet sind. Damit kann eine solche Anlage nicht nach Art eines Containers von derartigen Trägerfahrzeugen verfahren werden, sondern vielmehr muß ein jeweiliger Zuschnitt an ein solches Fahrzeug erfolgen, um die nötige Bodenfreiheit in jedem Fall zu gewährleisten. Bei Transporten über Eisenbahn oder Schiff wird sogar eine Teildemontage notwendig.Antenna systems are also known from the prospectus of the applicant W 477 f / sp. 285,500 H. According to Figs. 9738 and 44328, they have laterally pivotable booms that have vertical support cylinders at the ends, against which the booms can be braced on the ground. Movable operating bars are attached to the chassis of the carrier vehicle or to the base frame of the mast. The disadvantage of this known system is that it is a must have certain ground clearance because the cantilevers are designed as sloping beams or structures on which the vertical support cylinders are arranged at the ends. This means that such a system cannot be moved in the manner of a container by such carrier vehicles, but rather must be tailored to such a vehicle in order to ensure the necessary ground clearance in any case. Partial dismantling is even necessary for transport by rail or ship.

Aus dem gleichen Prospekt ist eine weitere Antennenanlage mit einem teleskopierbaren und durch seitliche Ausleger abstützbaren Mast zu entnehmen (51243, 51238). Diese Anlage verfügt über einen Grundrahmen, an dem die ausschwenkbaren Ausleger über eine schräggestellte Achse angelenkt sind. Dadurch ist es möglich, die an den Enden die ausfahrbaren Stützfüße aufweisenden Ausleger auf die Höhe des Grundrahmens hochzuschwenken, so daß sich insgesamt günstige Abmessungen ergeben. Die bekannte Antennenanlage ist allerdings nur für relativ leichte Einheiten vorgesehen und mit von Hand ausfahrbaren Stützfüßen und Auslegern ausgerüstet. Bei größeren Anlagen würden die Auslegerenden sehr weit überstehen bzw. könnten nicht ungehindert eingeklappt werden. Bei beiden Anlagen fehlt eine Abspannung des Mastes, die den Betrieb von z.B. Richtantennen ermöglichen.Another antenna system with a telescopic mast that can be supported by side arms can be found in the same brochure (51243, 51238). This system has a base frame on which the swing-out booms are articulated via an inclined axis. As a result, it is possible to pivot the arms which have the extendable support feet at the ends up to the height of the base frame, so that overall favorable dimensions result. However, the known antenna system is only intended for relatively light units and is equipped with support feet and brackets which can be extended by hand. With larger systems, the boom ends would protrude very far or could not be folded in unhindered. In both systems, the mast is not braced, which means that e.g. Enable directional antennas.

Aus der DE-OS 31 05 149.9-25 ist ein aussteifbares Viergelenksystem bekannt, allerdings dort eingesetzt als Abstützvorrichtung für Bagger und Kräne. Dieses Viergelenksystem kann mit Knickstreben nicht gleichgesetzt werden, zumal es viel aufwendiger baut und auch im zusammengefahrenen Zustand keine ausreichende Platzersparnis bringt. Weiter ist aus der DE-GM 76 39 621 ein Stützträger für Baumaschinen bekannt, bei dem eine Art Abstützzylinder aus der Senkrechten in den Ausleger selbst hineinverschwenkt werden kann. Hier ist der Ausleger allerdings als Teleskopbalken und der Abstützzylinder selbst um ein Gelenk verschwenkbar ausgebildet, so daß sich insgesamt eine relativ aufwendige, andererseits aber nicht vom Abstützzylinder her gesehen stabile Ausbildung ergibt, die einen aufwendigen teleskopierbaren Ausleger erfordert. Beide bekannten Systeme weisen eine sehr geringe und damit für Antennenanlagen unbefriedigende Ausladung auf.From DE-OS 31 05 149.9-25 a stiff four-link system is known, but used there as a support device for excavators and cranes. This four-bar system cannot be equated with articulated struts, especially since it is much more complex to build and does not save sufficient space even when it is closed. Furthermore, a support bracket for construction machinery is known from DE-GM 76 39 621, in which a type of support cylinder can be pivoted from the vertical into the boom itself. Here However, the boom is designed as a telescopic beam and the support cylinder itself can be pivoted about an articulation, so that overall a relatively complex, but not seen from the support cylinder, stable design results which requires a complex telescopic boom. Both known systems have a very small and therefore unsatisfactory projection for antenna systems.

Der Erfindung liegt die Aufgabe zugrunde, eine Antennenanlage mit containermäßigen Abmaßen zu schaffen, die günstig zu transportieren, einfach aufzustellen und zu demontieren ist und über eine große Standsicherheit durch weit ausladende Ausleger verfügt, die so ausgebildet sind, daß die Antennenanlage auch im extrem unebenen Gelände aufzustellen ist.The invention has for its object to provide an antenna system with container-like dimensions, which is inexpensive to transport, easy to set up and dismantle and has great stability thanks to wide cantilever arms, which are designed so that the antenna system even in extremely uneven terrain is to be set up.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß die vorderen und hinteren Ausleger als zweiteiliges Tragwerk ausgebildet sind, deren äußeres Teilstück, welches den Stützzylinder trägt, über ein horizontal angeordnetes Gelenk gegenüber dem mit dem Grundrahmen verbundenen inneren Teilstück verschwenkbar ist und eine Seilrolle aufweist, über die ein von einer dem Tragwerk zugeordneten Seilwinde betätigbares Spannseil zum Mastkopf geführt ist, und daß beide Teilstücke des vorderen und hinteren Ausleger jeweils als Ganzes mit dem Grundrahmen über eine Knickstrebe verbunden sind, wobei jede der Knickstreben über einen zugeordneten Hydraulikzylinder ein- und wieder ausknickbar ist.The object is achieved in that the front and rear booms are designed as a two-part structure, the outer section, which supports the support cylinder, can be pivoted via a horizontally arranged joint relative to the inner section connected to the base frame and has a rope pulley via which a tension cable which can be actuated by a cable winch assigned to the supporting structure is guided to the mast head, and that both sections of the front and rear brackets are each connected as a whole to the base frame via an articulated strut, each of the articulated struts being able to be folded in and out again via an associated hydraulic cylinder.

Eine derartige Antennenanlage kann deshalb containermäßig transportiert werden, weil die seitlich ausfahrbaren bzw. ausschenkbaren Ausleger aus einem stabilen z.B. Gittertragwerk so zusammengelegt und hochgefahren werden können, daß sie auch im eingefahrenen Zustand oberhalb des Grundrahmens bzw. oberhalb der Ladefläche des Trägerfahrzeuges angeordnet werden können. Vorteilhafterweise wird beim Zusammenfahren des Auslegers das Spannseil mitbenutzt, da es an dem einklappbaren Teilstück des Auslegers über eine Seilrolle geführt ist und damit dieses Teilstück zum Einschwenken bringt. Gleichzeitig wird der Ausleger selbst über eine Knickstrebe hydraulisch aus- und eingeschwenkt. Damit kann eine derartige Antennenanlage, abgesehen von dem Ausfahren des Tragmastes, selber in ausgesprochen kurzer Zeit so montiert werden, daß dann auch ein entsprechend hoher Mast ausgefahren werden kann, ohne daß die Gefahr besteht, daß er durch den Wind oder sonstige Belastungen gefährdet wird und vor allem, daß er aufgrund der Abspannung für Richtfunkeinsätze sicher verwendet werden kann. Die anmeldungsgemäße Antennenanlage verfügt damit über verschwenkbare Ausleger, die so hoch und so eingeschwenkt werden können, daß die gesamte eingefahrene Anlage containermäßig auf einem Trägerfahrzeug problemlos abtransportiert oder weitertransportiert werden kann. Vorteilhaft ermöglichen diese Ausleger auch bei extrem unebenem Boden einen sicheren Stand und dabei eine sichere Ausrichtung der Antenne.Such an antenna system can therefore be transported in a container-like manner because the laterally extendable or swing-out booms can be folded up and raised from a stable lattice structure, for example, in such a way that they can be arranged above the base frame or above the loading area of the carrier vehicle even when retracted. Advantageously, when Moving the jib together uses the tensioning cable, since it is guided on the foldable section of the jib via a cable pulley and thus causes this section to swivel in. At the same time, the boom itself is hydraulically swung in and out using a kink strut. Thus, such an antenna system, apart from the extension of the mast, can itself be installed in a very short time so that a correspondingly high mast can then be extended without the risk that it is endangered by the wind or other loads and above all, that it can be safely used for directional radio operations due to the guying. The antenna system according to the application thus has pivotable cantilevers which can be pivoted so high and so that the entire retracted system can be easily transported or transported on a carrier vehicle in terms of containers. Advantageously, these brackets enable a secure stand even when the floor is extremely uneven and the antenna is aligned securely.

Nach einer zweckmäßigen Ausbildung der Erfindung ist zur besseren und sicheren Montage und Demontage vorgesehen, daß den vorderen und hinteren Auslegern mit dem Grundrahmen verbundene Bedienungsstege zugeordnet sind, die Lenker aufweisen, mit denen die Bedienungsstege gegenüber dem Grundrahmen verschwenkbar sind. Zweckmäßig sind die Knickstreben und/oder jeweils das Teilstück des Auslegers mit den verschwenkbaren ausgebildeten Bedienungsstegen oder den diese führenden Lenkern über Koppelstangen verbunden. Damit ist es vorteilhaft möglich, gleichzeitig mit dem Ausschwenken der Ausleger auch die für die Montage und Demontage wichtigen Bedienungsstege mitabzuklappen oder auch bei anderer Ausführung herauszuziehen, die dann bereits während des weiteren Ausfahrens und Stabilisierens der Ausleger vom Bedienungspersonal begangen werden können. Diese Bedienungsstege dienen vor allem zur Betätigung der Hohlleitertrommeln, der Druckstabverriegelungen, der Antennenmontage und auch im Notbetrieb werden sie zwangsweise benötigt. Insgesamt ist es so möglich, ein relativ einfaches System von Bedienungsstegen an den Seiten des Trägerfahrzeugs vorzusehen, zumal die Bedienungsstege als solche in Alu-Hohlprofilkonstruktion ausgelegt werden können. Da sie einfach und sicher ausgeschwenkt und beim Einfahren der Ausleger auch wieder eingeschwenkt werden, können sie weitere Funktionen erfüllen, wobei die Erfindung hierzu vorsieht, daß sie während des Transportes zum Schutz der Anbauteile speziell der Hohlleiter dienen.According to an expedient embodiment of the invention, for better and safer assembly and disassembly, it is provided that the front and rear arms connected to the base frame are associated with control bars which have links with which the control bars can be pivoted with respect to the base frame. The articulated struts and / or in each case the section of the boom are expediently connected to the pivotable operating webs or the links which guide them via coupling rods. It is thus advantageously possible to fold down the operating webs that are important for assembly and disassembly at the same time as the booms are swung out, or to pull them out in the case of another design, which can then be used by the operating personnel during the further extension and stabilization of the booms. These operating bars are used primarily to actuate the waveguide drums, the push rod locks, the antenna assembly and also in emergency operation they are required. Overall, it is possible in this way to provide a relatively simple system of operating bars on the sides of the carrier vehicle, especially since the operating bars can be designed as such in an aluminum hollow profile construction. Since they can be swiveled out simply and securely and can also be swiveled in again when the booms are retracted, they can perform further functions, the invention providing for this purpose that they serve to protect the attachments, in particular the waveguide, during transport.

Eine besonders zweckmäßige Ausbildung der Erfindung sieht vor, daß das den Stützzylinder tragende Teilstück der vorderen und hinteren Ausleger ein aus Grundstrebe und Stützstreben bestehendes Gitterdreieck bildend geformt ist, an dessen Grundstrebe der Stützzylinder angebracht ist und in dessen von den Stützstreben gebildeten Knotenpunkt das horizontal angeordnete Gelenk und an dessen dem Auslegerfuß gegenüberliegenden Knotenpunkt die Seilrolle angeordnet ist. Damit ist eine günstige und einfache Möglichkeit gegeben, den Stützzylinder zusammen mit dem ihn tragenden Teilstück in die eingeschwenkte Lage beim Einziehen des Spannseiles zu bringen bzw. umgekehrt ihn auszuklappen und zwar aufgrund des Eigengewichtes, da dann das Spannseil diese Möglichkeit freigibt. Das Gelenk ist dabei so angebracht, daß das Abklappen des den Stützzylinder tragenden Teilstücks aufgrund des Eigengewichtes auch gewährleistet ist, wozu es wie erläutert an dem entsprechenden Knotenpunkt und zwar an dem von den Stützstreben gebildeten Knotenpunkt des Gitterdreiecks vorgesehen ist.A particularly expedient embodiment of the invention provides that the section of the front and rear brackets supporting the support cylinder is formed to form a grid triangle consisting of a base strut and support struts, on the base strut of which the support cylinder is attached and in the node formed by the support struts the horizontally arranged joint and the rope pulley is arranged at the junction point opposite the jib foot. This is a cheap and easy way to bring the support cylinder together with the section supporting it into the swiveled-in position when pulling in the tensioning cable or, conversely, to unfold it because of its own weight, since the tensioning cable then releases this possibility. The hinge is attached so that the folding of the section supporting the support cylinder is also ensured due to its own weight, for which purpose it is provided, as explained, at the corresponding node, namely at the node of the lattice triangle formed by the support struts.

Um die notwendigen Abstützkräfte durch das Ausfahren des Stützzylinders aufbringen zu können, muß das den Stützzylinder tragende Teilstück gegenüber dem am Grundrahmen schwenkbar angebrachten Teilstück festlegbar sein. Dies wird dadurch erreicht, daß an der die Seilrolle tragenden Knotenpunkt des Gitterdreiecks ein im mit Grundrahmen verbundenen Teilstück geführter, in der ausgefahrenen Stellung sperrbarer Balken schwenkbar gelagert ist. Dieser Balken wird beim Herabklappen des Gitterdreiecks mitherausgezogen und kann dann in der Endstellung gesperrt werden, so daß die notwendigen Abstützkräfte ohne Probleme übergeleitet werden können. Das Sperren des Balkens erfolgt dabei zweckmäßigerweise dadurch, daß dem mit dem Grundrahmen verbundenen Teilstück eine über eine Spindel vor den Balken schwenkbare Segmentsperre zugeordnet ist, wobei der Balken am freien Ende und das Teilstück im Sperrzustand ineinandergreifende Bolzen und Haken aufweisen. Durch die entsprechenden Bolzen ist dabei gleichzeitig die Möglichkeit gegeben, im eingefahrenen bzw. im Transportzustand beide Teilstücke der Ausleger durch Einhaken so aneinander zu befestigen, daß sie den Transport auch unabhängig vom Spannseil ermöglichen, da sie direkt miteinander verbunden sind. Beim Ausschwenken und Lockern des Spannseils bzw. Herausziehen des Spannseiles aus der Seilwinde wird dann diese Sicherung gelöst und das den Stützzylinder tragende Teilstück kann herabklappen, um dann, wie geschildert, durch den Balken sicher gesperrt zu werden.In order to be able to apply the necessary support forces by extending the support cylinder, the section supporting the support cylinder must be fixable relative to the section pivotably attached to the base frame. This is achieved in that on the cable pulley carrying Node of the lattice triangle is a pivoted bar guided in the section connected to the base frame and lockable in the extended position. This bar is pulled out when the grid triangle is folded down and can then be locked in the end position so that the necessary supporting forces can be transferred without problems. The bar is advantageously locked in that the segment connected to the base frame is assigned a segment lock which can be pivoted via a spindle in front of the beam, the bar having interlocking bolts and hooks at the free end and the segment in the locked state. Through the corresponding bolts, it is simultaneously possible to fasten both sections of the boom to one another in the retracted or in the transport state by hooking them in such a way that they also make it possible to transport them independently of the tensioning cable, since they are directly connected to one another. When swinging out and loosening the tensioning cable or pulling out the tensioning cable from the winch, this securing is then released and the section carrying the support cylinder can fold down, in order then, as described, to be securely blocked by the beam.

Eine das Seil als solches vorteilhaft schonende Ausführung der Erfindung sieht vor, daß die dem Grundrahmen zugeordnete Seilwinde als hydraulisch angetriebene Friktionswinde ausgebildet ist. Da die Seile aufgrund der von ihnen zu übernehmenden Kräfte eine ausgesprochen wichtige Funktion erfüllen, werden sie entsprechend gesichert, vor allem durch Aufbringen einer entsprechenden Beschichtung. Diese Beschichtung bleibt erhalten, weil die Friktionswinde entsprechend schonend arbeitet. Darüber hinaus ist vorteilhafterweise vorgesehen, daß die Abspannseilvorspannkraft aller Friktionswinden gemeinsam überwacht und hydraulisch geregelt ist. Während des Betriebes des Tragmastes bzw. der zugeordneten Antennenanlage ist so dafür Sorge getragen, daß die Abspannseile jeweils mit gleichmäßiger Anzugkraft bzw. Vorspannkraft beaufschlagt sind. Da alle vier Friktionswinden gleichzeitig angeschlossen sind und den gleichen Andruck aufbringen, ist eine gleichmäßige Absicherung des Tragmastes gewährleistet, ohne daß dazu zusätzliche Maßnahmen erforderlich würden.An embodiment of the invention which is advantageous for protecting the rope as such provides that the rope winch assigned to the base frame is designed as a hydraulically driven friction winch. Since the ropes perform an extremely important function due to the forces to be taken over by them, they are secured accordingly, especially by applying an appropriate coating. This coating is retained because the friction winch works gently. In addition, it is advantageously provided that the guy rope pretensioning force of all friction winches is jointly monitored and hydraulically controlled. During operation of the mast or the associated antenna system, care is taken to ensure that the guy ropes are each subjected to a uniform tightening force or pretensioning force. Since all four friction winches are connected at the same time and apply the same pressure, a uniform protection of the mast is guaranteed without additional measures being necessary.

Das Abklappen des den Stützzylinder tragenden Teilstücks, das ja erfindungsgemäß als Gitterdreieck ausgebildet ist, wird allein durch das Eigengewicht erreicht, wobei das Eigengewicht noch erhöht werden kann, indem seitlich am Stützzylinder Konsolen für die achteckig oder rund ausgebildeten Bodenplatten vorgesehen sind, wobei die Bodenplatten über Schnellverschlüsse verfügen, die mit denen dem Stützzylinder zugeordneten Kugelgelenkaufnahmen korrespondieren. Damit ist gleichzeitig die Möglichkeit gegeben, nach dem Ausklappen des Gitterdreiecks die Bodenplatten aus den Konsolen zu lösen und dann durch die Schnellverschlüsse schnell mit dem Stützzylinder zu verbinden, um dann auch bei unebenem Boden eine gleichmäßige Abstützung zu gewährleisten. Vorteilhaft ist aber, daß aufgrund des Gewichtes der Konsolen und der Bodenplatten das entsprechende Teilstück des Auslegers schnell abgesenkt bzw. ausgeklappt werden kann.The folding of the section supporting the support cylinder, which is designed according to the invention as a lattice triangle, is achieved solely by the dead weight, whereby the dead weight can be increased even further by providing consoles for the octagonal or round-shaped base plates on the side of the support cylinder, the base plates being above Have quick-release fasteners that correspond to the ball joint receptacles assigned to the support cylinder. This also gives you the option of detaching the base plates from the brackets after unfolding the lattice triangle and then quickly connecting them to the support cylinder using the quick-release fasteners, in order to ensure even support even on uneven floors. However, it is advantageous that, due to the weight of the brackets and the base plates, the corresponding section of the jib can be quickly lowered or folded out.

Um beim Einfahren des Tragmastes das überflüssige Spannseil günstig und schonend lagern zu können, ist vorgesehen, daß den Friktionswinden das Ende des Spannseiles lastlos speichernde Magazintrommeln zugeordnet sind. Damit ist das Ende des Spannseils immer sicher untergebracht, stellt weder eine Behinderung bei den Arbeitern dar, noch besteht die Gefahr, daß es durch Umwelteinflüsse o.ä. beschädigt wird.In order to be able to store the superfluous tensioning cable cheaply and gently when the support mast is retracted, it is provided that the friction winches are assigned to the end of the tensioning rope without load-storing magazine drums. So that the end of the tensioning rope is always safely housed, does not represent a hindrance for the workers, nor is there a risk that it will be caused by environmental influences or the like. is damaged.

Eine sichere Führung des Spannseils im Bereich der Ausleger ist erfindungsgemäß dadurch gesichert, daß die Seilrolle pendelnd am Teilstück gelagert ist. Gleichzeitig ist dadurch auch sichergestellt, daß jeweils unabhängig vom Einschwenkvorgang des zugeordneten Auslegers immer die notwendige Kraft aufgebracht werden kann, um das Einklappen oder Einschwenken des entsprechenden Teilstücks mit dem Stützzylinder zu gewährleisten. Optimal können so über die Seilrolle auch große Seillängen geführt werden, ohne daß ein Verhaspeln oder ein Abrutschen des Spannseiles zu befürchten ist.According to the invention, reliable guidance of the tensioning rope in the area of the outrigger arms is ensured in that the rope pulley is mounted on the section in an oscillating manner. At the same time, this also ensures that, regardless of the pivoting-in process of the assigned boom, the necessary force can be applied to ensure the folding or swiveling of the corresponding section with the support cylinder. In this way, large rope lengths can be optimally guided over the rope pulley without fear that the tension rope will become tangled or slip.

Die Erfindung zeichnet sich insbesondere dadurch aus, daß eine containermäßig vorteilhaft transportierbare Antennenanlage mit Tragmast und Grundrahmen geschaffen ist, die ohne Schwierigkeiten auf das Chassis bzw. die Ladefläche des Trägerfahrzeuges aufgebracht werden kann, weil die dem Grundrahmen zugeordneten Ausleger auf Containermaß zusammengelegt werden können. Die für das Abstützen des Tragmastes wichtigen Ausleger sind so eingeklappt, daß sie beim Transport keinerlei Behinderung darstellen. Sie werden beim Einklappen durch das Abspannseil mitbetätigt und in die Transportstellung gebracht, ohne daß hier ein zusätzlicher Eingriff der Bedienungsmannschaften erforderlich würde. Gleichzeitig werden auch die Bedienungsstege miteingeklappt, die dann anschließend optimal auch noch als Sicherung der dahinterliegenden Maschinenteile Mitverwendung finden können. Umgekehrt werden über die den Knickstreben zugeordnete Hydraulikzylinder die Ausleger ausgeschwenkt. Durch entsprechendes Nachgeben und Nachführen des Spannseiles schwenkt gleichzeitig auch das eingeschwenkte Teilstück des Auslegers aus, um dann in der ausgeschwenkten Stellung über den Balken arretiert zu werden. Zum Höhenausgleich wird der jedem Ausleger zugeordnete Stützzylinder ausgefahren, um so das ganze System auch gleichzeitig zu sichern. Mit dem Ausschwenken des Auslegers erfolgt dann auch gleichzeitig wieder das Ausschenken des zugeordneten Bedienungssteges, der dann frühzeitig für ein Begehen der Anlage und damit zur Durchführung von Montagearbeiten zur Verfügung steht.The invention is characterized in particular by the fact that an antenna system with a supporting mast and base frame that is advantageously transportable is created, which can be applied to the chassis or the loading area of the carrier vehicle without difficulty, because the outriggers assigned to the base frame can be folded to container dimensions. The outriggers important for supporting the mast are folded in so that they do not represent any hindrance during transport. When they are folded in, they are operated by the guy rope and brought into the transport position without the need for additional intervention by the operating teams. At the same time, the operating bridges are also folded in, which can then also be optimally used to secure the machine parts behind them. Conversely, the booms are swung out via the hydraulic cylinders assigned to the articulated struts. By correspondingly giving in and guiding the tensioning rope, the swung-in section of the jib also swings out at the same time, so that it can then be locked in the swung-out position via the beam. To compensate for the height, the support cylinder assigned to each boom is extended in order to secure the entire system at the same time. When the boom is swung out, the associated operating dock is then also swung out at the same time, which is then available at an early stage for inspecting the system and thus for carrying out assembly work.

Fig. 1 zeigt eine mobile Antennenanlage mit ausgefahrenem Tragmast (1), an dessen Spitze Antennen (2) angebracht sind. Der Tragmast (1) befindet sich auf einem Trägerfahrzeug (3), auf dessen Chassis (4) bzw. Ladefläche (5) der gesamte Tragmast (1) mit der entsprechenden Abspannung während des Transportes gelagert werden kann. Das Trägerfahrzeug (3) verbleibt in der Regel bei der Antennenanlage. Da sie Containermaße aufweist, kann sie ohne Probleme auf der Eisenbahn oder auf Schiffen verfrachtet werden und zwar dann ohne Trägerfahrzeug (3).Fig. 1 shows a mobile antenna system with extended mast (1), antennas (2) are attached to the top. The support mast (1) is located on a carrier vehicle (3), on the chassis (4) or loading area (5) of which the entire support mast (1) can be stored with the appropriate guying during transport. The carrier vehicle (3) usually remains with the antenna system. Since it has container dimensions, it can be transported on the railroad or on ships without any problems and then without a carrier vehicle (3).

Zur Abspannung und Sicherung des Tragmastes (1) im ausgefahrenen Zustand dienen einmal die zwischen dem Mastkopf (6) und den vorderen Auslegern (7) und den hinteren Auslegern (8) angeordneten und verspannten Spannseile (9) sowie die entsprechend ausgeschwenkten vorderen und hinteren Ausleger (7, 8) selbst. Die Spannseile (9) sind dabei über Seilrollen (10) geführt, die den Auslegern (7, 8), wie noch weiter hinten erläutert ist, zugeordnet sind.To tension and secure the mast (1) when extended, the tensioning cables (9) arranged and tensioned between the mast head (6) and the front brackets (7) and the rear brackets (8) and the correspondingly swung out front and rear brackets are used (7, 8) itself. The tension cables (9) are over Rope pulleys (10), which are assigned to the arms (7, 8), as will be explained further below.

Die Ausleger (7, 8) sind am Grundrahmen (11) schwenkbar gelagert und bestehen aus zwei Teilstücken (12, 13). Dabei ist das vom Grundrahmen (11) her gesehen innere Teilstück (12) schwenkbar am Grundrahmen (11) gelagert, während das äußere Teilstück (13) den Stützzylinder (14) mit der Bodenplatte (15) trägt und schwenkbar mit dem Teilstück (12) verbunden ist. Stützzylinder (14) und Bodenplatte (15) verfügen über korrespondierende Verbindungsmittel, um so beide Teile für die Abstützung der mobilen Antennenanlage schnell miteinander verbinden zu können.The arms (7, 8) are pivotally mounted on the base frame (11) and consist of two sections (12, 13). The inner section (12) seen from the base frame (11) is pivotably mounted on the base frame (11), while the outer section (13) carries the support cylinder (14) with the base plate (15) and is pivotable with the section (12). connected is. Support cylinder (14) and base plate (15) have corresponding connecting means so that the two parts for supporting the mobile antenna system can be quickly connected to one another.

Fig. 2 zeigt eine Draufsicht auf den Grundrahmen (11), an dem die schwenkbar angeordneten bzw. ausgeführten Ausleger (7, 8) angeordnet sind. Der Tragmast (1) ist in ausgefahrener Stellung dargestellt. Die Spannseile (9) sind von Auslegern (7, 8) ausgehend am Tragmast (1) und zwar genauer gesagt am Mastkopf (6) zusammengeführt.Fig. 2 shows a plan view of the base frame (11), on which the pivotably arranged or executed arms (7, 8) are arranged. The support mast (1) is shown in the extended position. The tensioning ropes (9) are brought together from brackets (7, 8) on the mast (1) and more precisely on the mast head (6).

Die vorderen Knickstrecken (19) dienen gemäß Fig. 2 mit den sie betätigenden Hydraulikzylindern (20) gleichzeitig zum Abstützen und Verriegeln der Ausleger (7, 8). Die Ausleger sind somit sicher verstrebt und können die ihnen zugedachten Aufgaben voll erfüllen. die hinteren Knickstreben (24) werden über die Hydraulikzylinder (25) ausgefahren und entsprechend verriegelt. Mit den an den Stützzylindern (14) befestigten Bodenplatten (15) können die Stützzylinder auch bei extrem unebenen Gelände so ausgefahren werden, daß die Antennenanlage in der optimalen und sicheren Stellung betrieben werden kann. Über die Stützzylinder (14) erfolgt der notwendige Höhenausgleich und damit die genau waagerechte Lage des Grundrahmens (11).2 with the hydraulic cylinders (20) actuating them serve at the same time to support and lock the booms (7, 8). The booms are therefore safely braced and can fully fulfill the tasks intended for them. the rear buckling struts (24) are extended via the hydraulic cylinders (25) and locked accordingly. With the base plates (15) attached to the support cylinders (14), the support cylinders can be extended even on extremely uneven terrain so that the antenna system can be operated in the optimal and safe position. The necessary height compensation and thus the exactly horizontal position of the base frame (11) is carried out via the support cylinders (14).

Fig. 3 zeigt die beiden Teilstücke (12, 13) im eingeschwenkten und Fig. 4 im ausgeschwenkten Zustand. Deutlich wird dabei, daß das Teilstück (13) von einem Grundstrebe und Stützstrebe aufweisenden Gitterdreieck (30) gebildet ist, an dessen Grundstrebe (31) der Stützzylinder (14) angeordnet ist. Der von den Stützstreben gebildete Knotenpunkt (32) des Gitterdreiecks (30) trägt das horizontale Gelenk (33), um das Gitterdreieck (30) und damit das Teilstück (13) aus der Transportstellung gemäß Fig. 3 in die Arbeitsstellung gemäß Fig. 4 schwenken zu können, wobei dies aufgrund des Eigengewichtes des Teilstückes (13) erfolgt.Fig. 3 shows the two sections (12, 13) in the swung-in and Fig. 4 in the swung-out state. Clear is that the section (13) of a base strut and support strut having grid triangle (30) is formed, on the base strut (31) of the support cylinder (14) is arranged. The node (32) of the lattice triangle (30) formed by the support struts carries the horizontal joint (33) to pivot around the lattice triangle (30) and thus the section (13) from the transport position according to FIG. 3 into the working position according to FIG. 4 to be able to, this is due to the weight of the section (13).

An dem einen von Grundstrebe und Stützstrebe gebildeten Knotenpunkt (34) des Gitterdreiecks (30) und zwar gegenüberliegend zum Auslegerfuß (17) ist die Seilrolle (10) angeordnet, die beim Betätigen über die Seilwinde für das Wiedereinschwenken des Gitterdreiecks (30) und damit des Teilstückes (13) in die aus Fig. 3 ersichtliche Transportstellung Sorge trägt. Am Stützzylinder (14) sind außenseitig Konsolen (16) angebracht, an denen die Bodenplatte (15), wie in Fig. 3 gezeigt, festgeklemmt werden kann, um dann im ausgefahrenen Zustand des Teilstückes (13) gemäß Fig. 4 über entsprechende Schnellverschlüsse mit dem Auslegerfuß (17) verbunden zu werden.At the one of the base strut and support strut node (34) of the lattice triangle (30) and opposite to the cantilever foot (17), the cable pulley (10) is arranged, which when actuated via the cable winch for the pivoting back of the lattice triangle (30) and thus the Section (13) in the transport position shown in Fig. 3 takes care. On the outside of the support cylinder (14), brackets (16) are attached, on which the base plate (15), as shown in FIG. 3, can be clamped in order to then use the corresponding quick-release fasteners when the section (13) in accordance with FIG. 4 is extended to be connected to the boom foot (17).

In Fig. 4 ist der Ausleger mit ausgeschwenktem Teilstück (13) wiedergegeben. Diese ausgeschwenkte Stellung wird dadurch gesichert, daß an der kurzen Strebe des Gitterdreieckes (30) ein Balken (35) schwenkbar angeordnet ist, der gleichzeitig im Teilstück (12) geführt ist. Dadurch rutscht er aus der in Fig. 3 ersichtlichen Position in die aus Fig. 4 ersichtliche Position, in der über eine Spindel (36) eine Segmentsperre (37) vor den Balken (35) geschoben wird, so daß er, wie aus Fig. 5 ersichtlich, optimal gesichert ist. Balken (35) und Teilstück (12) verfügen über einen Bolzen (38) bzw. einen Haken (39), um die durch die Segmentsperre (37) gesicherte Verbindung zu ermöglichen. Gleichzeitig kann über den Bolzen (38) und eine z.B. korrespondierende Klinke am Teilstück (12) eine Sicherung im eingeschwenkten Zustand erreicht werden. Der schwenkbar mit dem Gitterdreieck verbundene Balken (35) ist dann auch bei Ausfall des Spannseiles in der Transportstellung vorteilhaft gesichert.In Fig. 4 the boom is shown with the section (13) swung out. This pivoted-out position is ensured in that a bar (35) is pivotally arranged on the short strut of the lattice triangle (30) and is simultaneously guided in the section (12). As a result, it slips from the position shown in FIG. 3 into the position shown in FIG. 4, in which a segment lock (37) is pushed in front of the bar (35) via a spindle (36), so that, as shown in FIG. 5 can be seen, is optimally secured. Beams (35) and section (12) have a bolt (38) or a hook (39) to enable the connection secured by the segment lock (37). At the same time, a fuse can be secured via the bolt (38) and a corresponding pawl on the section (12) pivoted-in state can be achieved. The bar (35) pivotally connected to the grid triangle is then advantageously secured in the transport position even if the tensioning cable fails.

Der aus den Fig. 3 und 4 ersichtliche Seilwinde ist als Friktionswinde (41) ausgebildet, wobei durch das Rückführseil (42) und das Spannseil (9) dafür Sorge getragen wird, daß mit dem Einziehen des Spannseiles (9) gleichzeitig auch ein Zurückschwenken des Teilstückes (13) erfolgt, wenn vorher die Segmentsperre (37) über die Spindel (36) weggeschwenkt bzw. weggedreht worden ist.3 and 4, the cable winch is designed as a friction winch (41), with the return cable (42) and the tensioning cable (9) ensuring that when the tensioning cable (9) is retracted, a swiveling back of the cable is carried out at the same time Part (13) takes place if the segment lock (37) has previously been pivoted or turned away via the spindle (36).

Fig. 6 und 7 zeigen die bereits aus Fig. 2 ersichtliche Abspannung und Absicherung der Ausleger (7, 8) durch die Knickstreben (19, 24). Außerdem wird verdeutlicht, daß die Knickstrebe (19) über die Koppelstange (22) mit dem Bedienungssteg (21) verbunden ist, um so das Mitverschwenken des Bedienungssteges (21) zu erreichen, der selbst über Lenker (23) geführt wird. Der Bedienungssteg (29) ist seinerseits über die Lenker (27) mit dem Grundrahmen (11) verbunden, wodurch ein gleichmäßiges Verschwenken des Bedienungssteges (29), der mit einem Sicherheitslichtgitter (28) belegt ist, erreicht wird, wobei eine gleichzeitige Verbindung des Bedienungssteges (29) über eine Koppelstange (26) mit dem Teilstück (12) vorhanden ist. Die Knickstreben (19, 24) verfügen in den Knickgelenken (43, 44) über eine Verbindung mit dem jeweiligen Hydraulikzylinder (20, 25).6 and 7 show the bracing and securing of the brackets (7, 8) already apparent from FIG. 2 by means of the buckling struts (19, 24). In addition, it is made clear that the buckling strut (19) is connected to the operating web (21) via the coupling rod (22), so as to achieve the pivoting of the operating web (21), which itself is guided via the handlebar (23). The operating web (29) is in turn connected to the base frame (11) via the handlebars (27), whereby a uniform pivoting of the operating web (29), which is covered with a safety light curtain (28), is achieved, with a simultaneous connection of the operating web (29) via a coupling rod (26) with the section (12). The articulated struts (19, 24) have a connection to the respective hydraulic cylinder (20, 25) in the articulated joints (43, 44).

Beim Ausschwenken der Ausleger (7, 8) werden über die Knickstreben (19, 24) gleichzeitig die einzelnen Bedienungsstege (21, 29) ausgeschwenkt, so daß sie begehbar werden. Umgekehrt wie beim Ausschwenken der Ausleger (7, 8) werden beim Einschwenken der Ausleger auch gleichzeitig über die Knickstreben (19, 24) bzw. die Lenker (22, 26) die einzelnen Bedienungsstege (21, 29) mitangehoben und zurückgeschwenkt. Die optimale Containerbreite kann eingehalten werden, weil die zusammengeklappten Ausleger (7, 8) vor die Bedienungsstege (21, 29) geschwenkt werden.When the booms (7, 8) are swung out, the individual operating webs (21, 29) are swung out simultaneously via the articulated struts (19, 24) so that they can be walked on. Conversely, as when swinging the boom (7, 8), the individual operating webs (21, 29) are also lifted and swung back at the same time via the articulated struts (19, 24) or the handlebars (22, 26) when the boom is swung in. The optimal container width can be maintained because the folded arms (7, 8) are pivoted in front of the service bars (21, 29).

Fig. 8 zeigt noch einmal das Transportfahrzeug (3) in Seitenansicht, wobei hier allerdings der gesamte Tragmast (1) und die Antennen (2) in die Transportstellung eingefahren worden sind. Deutlich wird hier, daß die einzelnen Ausleger (7, 8) mit ihren beiden Teilstücken (12, 13) jeweils so hochgezogen bzw. hoch eingefahren sind, daß sie das Containermaß gewährleisten. Auch die Bodenplatten (15) sind an den Stützzylindern (14) über die Konsolen (16) so günstig festgeklemmt und gelagert, daß sie in das gesamte Containermaß hineinpassen. Es ergibt sich damit eine insgesamt sehr kompakte Bauweise einer derartigen mobilen Antennenanlage mit aufgelastetem Tragmast (1).Fig. 8 shows again the transport vehicle (3) in a side view, although here the entire mast (1) and the antennas (2) have been moved into the transport position. It is clear here that the individual booms (7, 8) with their two sections (12, 13) are each raised or retracted so that they ensure the container dimensions. The base plates (15) are clamped and supported on the support cylinders (14) via the brackets (16) so cheaply that they fit into the entire container size. This results in an overall very compact design of such a mobile antenna system with a loaded mast (1).
