Description

Die vorliegende Erfindung betrifft eine Hubvorrichtung, umfassend

  • ein Fahrgestell, mit zwei Seitenteilen und wenigstens einem Querträger, wobei der Querträger die beiden Seitenteile miteinander verbindet,
  • zumindest eine Masteinheit, die einen sich in Hochrichtung der Hubvorrichtung erstreckenden Mast aufweist und
  • zumindest ein höhenverstellbares Anschlussmittel zum Anschluss eines Hebezeugs.
The present invention relates to a lifting device comprising
  • a chassis, with two side parts and at least one cross member, wherein the cross member connects the two side parts,
  • at least one mast unit, which has a mast extending in the vertical direction of the lifting device and

Hubvorrichtungen dieser Art sind in vielen Varianten aus dem Stand der Technik bekannt. Sie werden zum Heben und Senken sowie zum Transportieren von verschiedenen Gegenständen oder sogar zum Transport von Personen verwendet.Lifting devices of this type are known in many variants from the prior art. They are used for lifting and lowering as well as for transporting various objects or even for transporting persons.

Je nach zu transportierender oder zu hebender oder zu senkender Last, werden unterschiedliche Anforderungen an Hubvorrichtungen gestellt. Ist eine Hubvorrichtung für eine schwere Last vorgesehen oder soll eine Last in eine große Höhe gehoben werden, ist zum Beispiel ein anderes Fahrgestell sinnvoll als bei leichten Lasten und geringen Hubhöhen. Außerdem ist es möglich, dass besondere Umgebungen spezielle Fahrwerke erforderlich machen, damit die Last vom Startpunkt eines Transportes abgeholt oder am Zielpunkt abgeliefert werden kann.Depending on the load to be transported or lifted or lowered, different requirements are placed on lifting devices. If a lifting device is provided for a heavy load or if a load is to be lifted to a great height, for example a different chassis makes sense than with light loads and low lifting heights. In addition, it is possible that special environments may require special landing gear so that the load can be picked up from the starting point of a transport or delivered to the destination.

So kommt es, dass schon heute Hubvorrichtungen mit unterschiedlich breiten Fahrgestellen und unterschiedlich langen Fahrgestellen hergestellt werden.So it is that already today lifts are made with different widths chassis and different lengths of chassis.

Die unterschiedlichen Fahrgestelle machen derzeit Sondermodelle notwendig, die oft durch den Umbau eines Serienmodells geschaffen werden.The different chassis make currently special models necessary, which are often created by the conversion of a production model.

Solche Sondermodelle sind daher oft nur mit einem deutlichen Mehraufwand im Vergleich zu einem Serienmodell herstellbar. Das macht Sondermodelle dann häufig teuer. Auch kann auf die Nachfrage nach einem Hubwagen mit einem besonderen Fahrwerk nicht schnell reagiert werden.Such special models are therefore often only with a significant overhead in comparison to a production model produced. That makes special models often expensive. Also, the demand for a lift truck with a special suspension can not be responded quickly.

Hier setzt die vorliegende Erfindung an.This is where the present invention begins.

Der vorliegenden Erfindung liegt das Problem zugrunde, den unterschiedlichen Anforderungen an ein Fahrgestell eines Hubwagens zu genügen.The present invention is based on the problem to meet the different requirements for a chassis of a lift truck.

Dieses Problem wird erfindungsgemäß dadurch gelöst, dass das Fahrgestell modular ausgebildet ist. Modular in diesem Sinne, dass das Fahrgestell aus mehreren Teilen zusammengesetzt ist. Die Teile haben Verbindungsstrukturen, über die sie miteinander verbunden sind. Ein solches modulares Fahrgestell kann je nach den Anforderungen nach Art eines Baukastens aus unterschiedlichen Teilen zusammengesetzt werden, solange gegeneinander austauschbare Teile gleiche Verbindungsstrukturen zur Verbindung mit den anderen Teilen des Fahrgestells oder des Hubwagens aufweisen. Die Teile können monolithisch sein.This problem is inventively achieved in that the chassis is modular. Modular in this sense, that the chassis is composed of several parts. The parts have connecting structures through which they are connected. Such a modular chassis may be composed of different parts depending on the requirements of a type of construction kit, as long as mutually exchangeable parts have the same connection structures for connection to the other parts of the chassis or the lift truck. The parts can be monolithic.

Bei einer erfindungsgemäßen Hubvorrichtung können zum Beispiel die Seitenteile und der Querträger Module des Fahrgestells sein. So können die Seitenteile variiert werden, um speziellen Anforderungen zu genügen, ohne dass der Querträger verändert werden muss. Umgekehrt kann der Querträger variiert werden, ohne dass die Seitenteile verändert werden müssen. Lediglich die Verbindungsstrukturen müssen beibehalten werden, damit die Verbindung zwischen den Teilen hergestellt werden kann.In a lifting device according to the invention, for example, the side parts and the cross member may be modules of the chassis. Thus, the side panels can be varied to meet specific requirements, without the crossbar must be changed. Conversely, the cross member can be varied without the side parts must be changed. Only the connection structures must be maintained so that the connection between the parts can be made.

Der Quertäger kann monolithisch ausgebildet sein.The cross member may be monolithic.

Nicht nur das Fahrgestell als gesamtes, auch die Seitenteile des Fahrgestells können modular ausgebildet sein. Dadurch wird die Modularität des gesamten Fahrgestells erhöht.Not only the chassis as a whole, but also the side parts of the chassis can be modular. This increases the modularity of the entire chassis.

Jedes Seitenteil kann mehrere monolithische Abschnitte umfassen, die miteinander verbunden sind und Module der modularen Seitenteile sind. Die Abschnitte jedes Seitenteils können Verbindungsstrukturen haben, über die sie mit einem weiteren Abschnitt des Seitenteiles und/oder mit dem Querträger verbunden sind.Each side member may comprise a plurality of monolithic sections joined together and modules of the modular side panels. The sections of each side part may have connecting structures, via which they are connected to a further section of the side part and / or to the cross member.

Jedes Seitenteil einer erfindungsgemäßen Hubvorrichtung kann einen ersten Abschnitt, einen zweiten Abschnitt und einen dritten Abschnitt umfassen, die miteinander verbunden sind.Each side part of a lifting device according to the invention may comprise a first portion, a second portion and a third portion, which are interconnected.

Beispielsweise kann der Querträger mit einem dritten Abschnitt jedes Seitenteils verbunden sein.For example, the cross member may be connected to a third portion of each side part.

Vorteilhaft ist es, wenn die ersten Abschnitte, die zweiten Abschnitte und/oder der Querträger Hohlprofile mit einem in ihrer Haupterstreckungsrichtung gleichförmigen Querschnittsprofil sind. Die Hohlprofile können Rohre, insbesondere Rechteckrohre sein, die durch Ablängen aus einem längeren Rohr hergestellt werden können. Dadurch ist möglich ohne besondere Lagerhaltung für die Module der Seitenteile oder der Querträger, je nach Anforderung an den zu fertigenden Hubwagen, zur Herstellung der Module die benötigten Rohre abzuschneiden.It is advantageous if the first sections, the second sections and / or the cross member are hollow profiles with a uniform in their main extension direction cross-sectional profile. The hollow sections may be tubes, in particular rectangular tubes, which can be produced by cutting to length from a longer tube. This makes it possible without special storage for the modules of the side parts or the cross member, depending on the requirements of the truck to be manufactured, to cut off the tubes required for the production of the modules.

Gemäß der Erfindung können die ersten Abschnitte, die zweiten Abschnitte und/oder der Querträger zumindest an jeweils einem Ende und/oder der Querträger an beiden Enden je eine Ausnehmung als Verbindungsstruktur aufweisen.According to the invention, the first sections, the second sections and / or the cross member may at least at one end and / or the cross member at both ends each have a recess as a connection structure.

Gemäß der Erfindung können die dritten Abschnitte hervorstehende Bereiche aufweisen, die jeweils einen Querschnitt aufweisen, der wenigstens einem lichten Querschnitt einer als Verbindungsstruktur vorgesehenen Ausnehmung entspricht. Die hervorstehenden Bereiche können dann zur Verbindung des dritten Abschnitts mit dem ersten und/oder dem zweiten Abschnitt und/oder mit dem Querträger in deren Ausnehmungen eingesteckt werden.According to the invention, the third sections can have protruding areas, which each have a cross section which corresponds to at least one clear cross section of a recess provided as a connection structure. The protruding areas can then be plugged into the recesses for connecting the third section to the first and / or the second section and / or to the cross member.

Das bedeutet, dass der erste Abschnitt, der zweite Abschnitt und/oder der dritte Abschnitt jedes Seitenteils durch Steckverbindungen miteinander verbunden sind. Ebenso können die dritten Abschnitte der Seitenteile und der Querträger durch Steckverbindungen miteinander verbunden sein. Die Steckverbindungen können durch Stifte, Schrauben oder anderes gegen ein Lösen gesichert sein.This means that the first section, the second section and / or the third section of each side part are connected to one another by plug connections. Likewise, the third portions of the side parts and the cross member may be interconnected by connectors. The connectors can be secured by pins, screws or other against loosening.

Der dritte Abschnitt einer erfindungsgemäßen Hubvorrichtung kann ein Gussteil sein.The third section of a lifting device according to the invention may be a cast part.

Die ersten Abschnitte der Seitenteile können gleich sein. Ebenso können die zweiten Abschnitte der Seitenteile gleich sein. Dagegen können die dritten Abschnitte der Seitenteile flächensymmetrisch zueinander sein.The first sections of the side panels can be the same. Likewise, the second portions of the side panels may be the same. By contrast, the third sections of the side parts can be surface-symmetrical to each other.

An den Seitenteilen können über Rollenhalter Rollen befestigt sein. Die Rollenhalter und die Rollen können paarweise gleich sein.On the side panels can be attached via roller holder rollers. The roll holders and the rolls can be the same in pairs.

Unter Bezugnahme auf Fig. 1 bis 3 umfasst eine Hubvorrichtung H, die gemäß einem ersten Ausführungsbeispiel der vorliegenden Erfindung ausgeführt ist, ein Fahrgestell 2 sowie eine Masteinheit 1, die an dem Fahrgestell 2 angebracht ist.With reference to Fig. 1 to 3 comprises a lifting device H, which is carried out according to a first embodiment of the present invention, a chassis 2 and a mast unit 1, which is mounted on the chassis 2.

Das Fahrgestell 2 weist zwei sich parallel zueinander erstreckende Seitenteile 3, 4 auf, die mittels eines Querträger 5, der sich in Querrichtung zwischen diesen erstreckt, miteinander verbunden sind.The chassis 2 has two mutually parallel side parts 3, 4, which are interconnected by means of a cross member 5, which extends transversely between them.

Bei dem Querträger 5 (siehe insbesondere Fig. 7) kann es sich um ein Rechteckrohr oder ein anderes Profilteil mit einem über seine Länge gleichförmigen Profilquerschnitt handeln.In the cross member 5 (see in particular Fig. 7 ) may be a rectangular tube or another profile part with a uniform over its length profile cross-section.

Jedes der beiden Seitenteile 3, 4 umfasst einen vorderen (ersten) Abschnitt 30, 40 (siehe insbesondere Fig. 4), der vorzugsweise als Profilteil mit gleichförmigem Querschnitt, insbesondere als Rechteckrohr, ausgebildet ist. Jeder der beiden vorderen Abschnitte 30, 40 der Seitenteile 3, 4 weist ein freies Ende auf, an dem über einen ersten Rollenhalter 33, 43 jeweils eine Rolle 44 angebracht ist. Diese beiden Rollen 34, 44 können relativ zu einer Hochachse der Hubvorrichtung H drehbar sein (Lenkrollen). Es könnten aber auch Bockrollen verwendet werden.Each of the two side parts 3, 4 comprises a front (first) section 30, 40 (see in particular Fig. 4 ), which is preferably formed as a profile part with a uniform cross-section, in particular as a rectangular tube. Each of the two front portions 30, 40 of the side parts 3, 4 has a free end, to which a roller 44, a roller 44 is attached via a first roller holder 33, respectively. These two rollers 34, 44 can relative to a vertical axis of the Lifting device H be rotatable (castors). But it could also be used Bockrollen.

Jedes der beiden Seitenteile umfasst ferner einen hinteren (zweiten) Abschnitt 31, 41 (siehe insbesondere Fig. 5), der vorzugsweise ebenfalls als Profilteil mit gleichförmigem Querschnitt, insbesondere als Rechteckrohr, ausgebildet ist. An den freien Enden der beiden hinteren Abschnitte 31 , 41 der Seitenteile 3, 4 können über je einen zweiten Rollenhalter 35, 45 jeweils eine Lenkrolle 36, 46 angebracht sein. Die Lenkrollen 34, 44, 36, 46 sind um die Hochachse der Hubvorrichtung H bewegbar, so dass mit ihnen zum Beispiel Lenkbewegungen durchgeführt werden können. Die Bewegbarkeit der Rollen um die Hochachse kann durch einen Mechanismus blockiert oder zumindest eingeschränkt werden. Alternativ können dies auch Bockrollen sein.Each of the two side parts further comprises a rear (second) section 31, 41 (see in particular Fig. 5 ), which is preferably also designed as a profile part with a uniform cross-section, in particular as a rectangular tube. At the free ends of the two rear portions 31, 41 of the side parts 3, 4 may each have a second roller holder 35, 45 each have a steering roller 36, 46 may be attached. The castors 34, 44, 36, 46 are movable about the vertical axis of the lifting device H, so that, for example, steering movements can be performed with them. The mobility of the rollers about the vertical axis can be blocked or at least limited by a mechanism. Alternatively, these can also be castors.

Der vordere Abschnitt 30, 40 und der hintere Abschnitt 31, 41 eines jeden der beiden Seitenteile 3, 4 sind über einen mittleren (dritten) Abschnitt 32, 42 (siehe insbesondere Fig. 6), der vorzugsweise als Gussteil ausgebildet ist, miteinander verbunden. Bei dem Gussteil kann es sich um ein Aluminium-(Druck)-Gussteil, ein Graugussteil oder ein anderes Gussteil handeln. Alternativ könnte auch eine Schweißkonstruktion aus Metall oder eine Kunststoffkonstruktion, insbesondere eine Spritzguss-, Laminat- oder eine andere Kunststoffkonstruktion verwendet werden. Ebenso ist es möglich, dass die Abschnitte 32, 42 aus Profilteilen zusammen gesetzt sind, die fest miteinander verbunden sind.The front portion 30, 40 and the rear portion 31, 41 of each of the two side parts 3, 4 are over a middle (third) portion 32, 42 (see in particular Fig. 6 ), which is preferably formed as a casting, connected to each other. The casting may be an aluminum (pressure) casting, a cast iron part, or another casting. Alternatively, a welded construction made of metal or a plastic construction, in particular an injection molding, laminate or another plastic construction could be used. It is also possible that the sections 32, 42 are composed of profile parts, which are firmly connected.

An den mittleren Abschnitten 32, 42 der Seitenteile 3, 4 sind Strukturen 320, 420, 321, 421, 325, 425 zur Verbindung mit den vorderen Abschnitten 30, 40 und den hinteren Abschnitten 31, 41 sowie zur Verbindung mit dem Querträger 5 vorgesehen. Die Strukturen 325, 425 zur Verbindung mit dem Querträger 5 können monolithisch mit den übrigen mittleren Abschnitten 32, 42 verbunden sein. Es ist ebenso möglich, diese an den übrigen Abschnitten 32, 42 anzufügen, um bei der Montage der Fahrgestells Toleranzen ausgleichen zu können.Structures 320, 420, 321, 421, 325, 425 for connection to the front sections 30, 40 and the rear sections 31, 41 as well as for connection to the cross member 5 are provided at the middle sections 32, 42 of the side sections 3, 4. The Structures 325, 425 for connection to the cross member 5 may be monolithically connected to the remaining central sections 32, 42. It is also possible to attach these to the other sections 32, 42 in order to compensate for tolerances in the assembly of the chassis.

Sind als Querträger 5, als vordere Abschnitte 30, 40 und als hintere Abschnitte 31, 41 Rohre vorgesehen, können als Verbindungsstrukturen 321, 421 an dem mittleren Abschnitt 32, 42 der Seitenteile 3, 4 Stutzen vorgesehen sein, die in die Rohre eingesteckt und dort durch Schrauben 37, 48 oder andere Befestigungselemente fixiert sind.Are provided as a cross member 5, as front portions 30, 40 and as rear portions 31, 41 tubes, can be provided as connecting structures 321, 421 at the central portion 32, 42 of the side parts 3, 4 sockets, which are inserted into the tubes and there are fixed by screws 37, 48 or other fasteners.

Die Abschnitte 30, 31, 40, 41 können Rechteckrohre mit gleichem Querschnittsprofil sein. Vorzugsweise werden die Abschnitte 30, 31, 40, 41 durch Abtrennen von einem Rohr hergestellt. Vorzugsweise sind die vorderen Abschnitte 30, 40 identisch und auch die hinteren Abschnitte 31, 41 identisch. Ebenso sind die Rollenhalter 33, 43 identisch und die Rollenhalter 35, 45 identisch. Das gleiche gilt für die Rollen 34, 44, die ebenso identisch sind wie die Rollen 36, 46. Lediglich die mittleren Abschnitte 32, 42 der Seitenteile 3, 4 sind nicht identisch. Dafür sind diese flächensymmetrisch zu einer Fläche senkrecht zu einer Ebene, die durch Aufstandspunkte der Rollen 34, 44, 36, 46 auf einem Untergrund aufgespannt ist.The sections 30, 31, 40, 41 may be rectangular tubes with the same cross-sectional profile. Preferably, the sections 30, 31, 40, 41 are made by severing from a pipe. Preferably, the front portions 30, 40 are identical and also the rear portions 31, 41 are identical. Likewise, the roll holders 33, 43 are identical and the roll holders 35, 45 identical. The same applies to the rollers 34, 44, which are as identical as the rollers 36, 46. Only the central portions 32, 42 of the side parts 3, 4 are not identical. For this they are surface symmetrical to a surface perpendicular to a plane which is spanned by Aufstandsspunkte the rollers 34, 44, 36, 46 on a substrate.

Ein Vorteil des beschriebenen Fahrgestells 2 mit den u. a. aus den Abschnitten 30, 31, 32, 40, 41, 42 der Seitenteile 3, 4 und dem Querträger 5 aufgebauten Fahrgestell 2 ist, dass durch eine Variation der Längen des Querträgers 5 und der Abschnitte 30, 31, 32, 40, 41, 42 der Seitenteile 3, 4 ohne großen technischen Aufwand Fahrgestelle 2 mit anderen Dimensionen geschaffen werden können. Durch die Wahl eines kürzeren oder längeren Querträgers 5 kann ein schmaleres oder breiteres Fahrgestell 2 geschaffen werden. Eine Änderung der Seitenteile 3, 4 oder der Masteinheit 1 ist dazu nicht oder nicht grundsätzlich erforderlich. Durch eine Variation der Länge der Abschnitte 30, 31, 40, 41 der Seitenteile 3, 4 kann ein größerer oder kleinerer Überstand des Fahrgestelles 2 über die Masteinheit 1 nach vorne oder nach hinten erzielt werden. Die mittleren Abschnitte 32, 42 müssen dazu nicht geändert werden. Ebenso ist es möglich, anstelle der beschriebenen und in den Figuren dargestellten vorderen oder hinteren Abschnitte 30, 31, 40, 41 zumindest teilweise anders gestaltete Abschnitte für die Seitenteile 3, 4 zu wählen, wenn das zum Beispiel der Einsatzzweck des Hubwagens sinnvoll oder notwendig macht. Der vordere Abschnitt 30, 40 oder der hintere Abschnitt 31, 41 könnten beispielsweise Abkröpfungen aufweisen oder ähnliches.An advantage of the chassis 2 described with the inter alia, from the sections 30, 31, 32, 40, 41, 42 of the side parts 3, 4 and the cross member 5 constructed chassis 2 is that by a variation of the lengths of the cross member 5 and the sections 30th , 31, 32, 40, 41, 42 of the side parts 3, 4 without much technical effort chassis 2 can be created with other dimensions. By choosing a shorter or longer cross member 5 can narrower or wider chassis 2 are created. A change of the side parts 3, 4 or the master unit 1 is not or not required in principle. By varying the length of the sections 30, 31, 40, 41 of the side parts 3, 4, a larger or smaller projection of the chassis 2 can be achieved via the mast unit 1 to the front or to the rear. The middle sections 32, 42 need not be changed. It is also possible, instead of the described and shown in the figures, front or rear portions 30, 31, 40, 41 at least partially differently shaped sections for the side parts 3, 4, if for example the purpose of the lift truck makes sense or necessary , The front portion 30, 40 or the rear portion 31, 41 could, for example, have offsets or the like.

Oberhalb der beiden Rollen 36, 46 erstreckt sich in Querrichtung des Fahrgestells 2 ein Bremsbetätigungsbügel 9, mittels dessen eine auf die beiden Rollen 36, 46 wirkende Bremseinrichtung festgestellt beziehungsweise wieder gelöst werden kann. Der Bremsbetätigungsbügel 9 ist an den Rollenträgern 35, 45 für die hinteren Rollen 36, 46 schwenkbar gelagert. Die Bremse ist auf herkömmliche Art und Weise ausgestaltet.Above the two rollers 36, 46 extends in the transverse direction of the chassis 2, a brake operating bracket 9, by means of which a force acting on the two rollers 36, 46 braking device can be detected or released again. The brake operating bracket 9 is pivotally mounted on the roller carriers 35, 45 for the rear rollers 36, 46. The brake is designed in a conventional manner.

Unter dem Querträger 5 ist ein Gehäuse 6 vorgesehen. In diesem Gehäuse 6 ist eine Antriebseinheit untergebracht, mit welcher ein nicht dargestelltes Hebezeug angehoben und abgesenkt werden kann. Die Antriebseinheit ist dazu in an sich bekannter Art und Weise über eine Spindel, die in der Masteinheit 1 angeordnet ist, mit einem Schlitten gekoppelt, der einerseits in dem Mast 10 verschiebbar angeordnet ist und andererseits mit dem Hebezeug verbunden ist.Under the cross member 5, a housing 6 is provided. In this housing 6, a drive unit is housed, with which a not shown hoist can be raised and lowered. The drive unit is for this purpose in a conventional manner via a spindle which is arranged in the master unit 1, coupled to a carriage, which is arranged on the one hand slidable in the mast 10 and on the other hand connected to the hoist.

Die Masteinheit 1 umfasst einen Mast 10 und eine Mastfuß 11.The mast unit 1 comprises a mast 10 and a mast foot 11.

Der Mastfuß 11 schafft die Verbindung zwischen dem Mast 10 und dem Querträger 5. Der Mastfuß 11 umfasst dazu ein erstes Teil 110, vorzugsweise in der Form einer Platte, insbesondere eines Metallbleches, die auf der Oberseite des Querträgers 5, vorzugsweise durch Verschrauben befestigt ist. In einem Winkel dazu, der einer Neigung des Mastes 10 entspricht, ist ein zweites Teil 111 vorgesehen, das zum einen mit dem ersten Teil 110 und zum anderen mit dem Mast 10 verbunden ist. Das zweite Teil ist ebenfalls vorzugsweise eine Platte, insbesondere ein Metallblech, die an die Rückseite des Mastes 10 geschraubt ist. Die beiden Teile 110, 111 sind vorzugsweise durch Schweißen miteinander verbunden. Wenigstens ein drittes Teil (nicht dargestellt) kann als Strebe vorgesehen sein, welches zusätzlich zur Schweißverbindung zwischen dem ersten und dem zweiten Teil 110, 111 eine Verbindung schafft. Dieses dritte Teil ist vorzugsweise dazu vorgesehen Drehmomente, die auf den Mast 10 wirken, abzufangen und vom ersten Teil 110 in das zweite Teil 111 des Mastfußes 10 abzuleiten. Das dritte Teil seinerseits kann über vierte Teile (nicht dargestellt), vorzugsweise ebenfalls Streben, gegenüber dem ersten Blech 110 abgestützt sein. Die Verbindung zwischen dem dritten Teil und dem ersten und zweiten Teil 110, 111 sowie dem oder den vierten Teilen und dem dritten und dem ersten Teil 110 ist ebenfalls durch Schweißen hergestellt.The mast base 11 provides the connection between the mast 10 and the cross member 5. The mast base 11 includes for this purpose a first part 110, preferably in the form of a plate, in particular a metal sheet, which is fastened on the upper side of the cross member 5, preferably by screwing. At an angle thereto, which corresponds to an inclination of the mast 10, a second part 111 is provided which is connected on the one hand to the first part 110 and the other with the mast 10. The second part is also preferably a plate, in particular a metal sheet, which is screwed to the back of the mast 10. The two parts 110, 111 are preferably connected to one another by welding. At least a third part (not shown) may be provided as a strut, which in addition to the welded connection between the first and the second part 110, 111 creates a connection. This third part is preferably provided to intercept torques acting on the mast 10 and to divert them from the first part 110 into the second part 111 of the mast base 10. The third part in turn can be supported against the first metal sheet 110 via fourth parts (not shown), preferably also struts. The connection between the third part and the first and second parts 110, 111 and the fourth part (s) and the third and the first part 110 is also made by welding.

Ein Vorteil der Masteinheit 1 mit dem beschriebenen oder einem funktional vergleichbaren Mastfuß 11 ist, dass die Masteinheit 1 mit diesem Mastfuß 11 an einer im Grunde beliebigen Basis befestigt werden kann. Die Basis kann im Grunde ein beliebiges Fahrgestell 2 sein und es ist nicht notwendig, dass das Fahrgestell 2 auf die vorbeschriebene Art und Weise gestaltet ist. Die Basis muss noch nicht einmal ein Fahrgestell 2 sein. Die Masteinheit 1 mit dem beschriebenen oder einem funktional vergleichbaren Mastfuß 11 kann an einer stationären Basis befestigt werden, zum Beispiel einem Sockel, einem Balken, einer Wand, einer auskragenden Platte o.a.An advantage of the mast unit 1 with the described or a functionally comparable mast base 11 is that the mast unit 1 can be attached to this mast base 11 on an essentially arbitrary base. The base may basically be any chassis 2 and it is not necessary that the chassis 2 be designed in the manner described above. The base does not even have to be a chassis 2. The mast unit 1 with the described or a functionally comparable Mastfuß 11 can be attached to a stationary base, for example, a pedestal, a beam, a wall, a cantilevered plate or the like

An einer Vorderseite des Mastes 10 ist ein Anschlussmittel 12 zum Anschluss des hier nicht explizit dargestellten Hebezeugs vorgesehen. Dieses Anschlussmittel 12 ist in einer Anschlussmittelführung 13, die in diesem Ausführungsbeispiel als sich in Hochrichtung des Mastes 10 erstreckende Führungskulisse ausgebildet ist, verschiebbar geführt, so dass ein Heben oder Senken des Anschlussmittels 12 zusammen mit dem daran angebrachten Hebezeug relativ zum Mast 10 möglich ist.At a front side of the mast 10, a connection means 12 is provided for connecting the hoist not explicitly shown here. This connection means 12 is displaceably guided in a connection means guide 13, which in this exemplary embodiment is designed as a guide slot extending in the vertical direction of the mast 10, so that a lifting or lowering of the connection means 12 together with the hoist attached thereto is possible relative to the mast 10.

Der Schlitten steht mit dem Anschlussmittel 12 zum Anschluss des Hebezeugs in Wirkverbindung und ermöglicht dadurch eine Aufbeziehungsweise Abwärtsbewegung des Anschlussmittels 12 relativ zum Mast 10.The carriage is in operative connection with the connection means 12 for connection of the hoist and thereby enables a Aufbeziehungsweise downward movement of the connection means 12 relative to the mast 10th

An einer Rückseite des Mastes 10 ist oberhalb des Mastfußes 11 ein Gehäuse 15 angebracht, innerhalb dessen eine Steuerungseinrichtung für den Hubmotor untergebracht ist, die an die Antriebseinheit angeschlossen ist und zur Steuerung der Funktionen des Hubmotors vorgesehen ist. Innerhalb des Gehäuses 15 ist ferner zumindest ein aufladbarer Akkumulator untergebracht, mittels dessen unter anderem die Steuerungseinrichtung für den Hubmotor sowie die Antriebseinheit gespeist werden können. Es ist auch eine leitungsgebundene Stromversorgung der Steuerungseinrichtung sowie der Antriebseinheit möglich.On a rear side of the mast 10, a housing 15 is mounted above the mast base 11, within which a control device for the lifting motor is housed, which is connected to the drive unit and is provided for controlling the functions of the lifting motor. Within the housing 15, at least one rechargeable accumulator is further housed, by means of which, inter alia, the control device for the lifting motor and the drive unit can be fed. It is also possible a line-connected power supply of the control device and the drive unit.

Oberhalb des Gehäuses 15 für die Steuerungseinrichtung des Hubmotors ist ein Handhabungsmittel 16 vorgesehen. Das Handhabungsmittel 16 weist einen Griffbügel 160 mit einem Basisabschnitt 161 auf, der sich beidseitig quer zum Mast 10 erstreckt und an einem sich in Hochrichtung des Mastes 10 erstreckenden Haltemittel 17 befestigt ist oder alternativ auch integral mit diesem ausgebildet sein kann. Das Haltemittel 17 ist in einer Führung 18 auf der Rückseite des Mastes 10 in Hochrichtung verschiebbar geführt, so dass eine Höhenverstellung des Haltemittels 17 mit dem daran angebrachten Handhabungsmittel 16 relativ zum Mast 10 möglich ist. Die Führung 18 ist in diesem Ausführungsbeispiel ebenfalls als Führungskulisse ausgebildet. Um das Haltemittel 17 mit dem daran angebrachten Handhabungsmittel 16 in der gewünschten Position zu fixieren, sind vorliegend z.B. zwei Halteschrauben 19a, 19b vorgesehen, die sich durch entsprechende Bohrungen des Haltemittels 17, die in Hochrichtung übereinander vorgesehen sind, hindurch erstrecken und innerhalb der Führung 18 festgelegt werden können. Nach dem Lösen der Halteschrauben 19a, 19b ist eine Höhenverstellung des Haltemittels 17 mit dem daran angebrachten Handhabungsmittel 16 möglich. Durch erneutes Festziehen der Halteschrauben 19a, 19b kann die Höhenposition des Handhabungsmittels 16 fixiert werden.Above the housing 15 for the control device of the lifting motor, a handling means 16 is provided. The handling means 16 has a handle bar 160 with a base portion 161 which extends transversely to the mast 10 on both sides and is fastened to a holding means 17 extending in the vertical direction of the mast 10 or, alternatively, can also be formed integrally therewith. The holding means 17 is slidably guided in a guide 18 on the back of the mast 10 in the vertical direction, so that a height adjustment of the holding means 17 with the attached handling means 16 relative to the mast 10 is possible. The guide 18 is also formed in this embodiment as a guide slot. In order to fix the holding means 17 with the handling means 16 attached thereto in the desired position, in the present example, two retaining screws 19a, 19b are provided, which extend through corresponding bores of the holding means 17, which are provided one above the other in the vertical direction, and within the guide 18th can be determined. After loosening the retaining screws 19a, 19b, a height adjustment of the holding means 17 with the handling means 16 attached thereto is possible. By re-tightening the retaining screws 19a, 19b, the height position of the handling means 16 can be fixed.

Der Griffbügel 160 weist ferner zwei Seitenabschnitte 162, 163 auf, die sich im Wesentlichen parallel zueinander und orthogonal von dem Basisabschnitt 161 weg erstrecken. Wie insbesondere in Fig. 1 zu erkennen, ist der Griffbügel 160 so angeordnet, dass die beiden Seitenabschnitte 162, 163 leicht schräg nach oben angestellt sind, um dadurch eine verbesserte Ergonomie zu erreichen. Das Handhabungsmittel 16 weist ferner zwei Griffteile 20, 21 auf, die an den freien Enden der beiden Seitenabschnitte 162, 163 befestigt sind. Alternativ können die beiden Griffteile 20, 21 auch integral mit dem Griffbügel 160 ausgebildet sein. Die beiden Griffteile 20, 21 erstrecken sich in Bezug auf die beiden Seitenabschnitte 162, 163 des Griffbügels 160 schräg nach unten und im Wesentlichen orthogonal zu diesen. Mittels der beiden Griffteile 20, 21 kann ein Benutzer die Hubvorrichtung H greifen und sie in der gewünschten Weise bewegen.The handle bar 160 further includes two side portions 162, 163 that extend substantially parallel to each other and orthogonal away from the base portion 161. As in particular in Fig. 1 can be seen, the handle 160 is arranged so that the two side portions 162, 163 are made slightly obliquely upward, thereby achieving improved ergonomics. The handling means 16 further comprises two handle portions 20, 21 which are secured to the free ends of the two side portions 162, 163. Alternatively, the two handle parts 20, 21 may also be formed integrally with the handle bracket 160. The two handle parts 20, 21 extend obliquely downwards and substantially orthogonal to the two side sections 162, 163 of the handle bracket 160. By means of the two handle parts 20, 21 can Users grab the lifting device H and move it in the desired manner.

Unter Bezugnahme auf Fig. 3 wird deutlich, dass jedes der beiden Griffteile 20, 21 einen zentralen Griffabschnitt 200, 210 aufweist, mittels dessen ein Benutzer das jeweilige Griffteil 20, 21 greifen kann. An jeden Griffabschnitt 200, 210 jedes der beiden Griffteile 20, 21 schließt sich seitlich ein äußerer, vorliegend geschlossen ausgebildeter Bügelabschnitt 201, 211 an. Diese äußeren Bügelabschnitte 201, 211 sind dazu in der Lage, die Verletzungsgefahr für einen Benutzer, insbesondere die Gefahr von Handverletzungen, zu verringern, wenn die Hubvorrichtung H im Bereich zumindest eines der beiden Griffteile 20, 21 zum Beispiel eine Berührung mit einem anderen Gegenstand oder einer Person erfährt.With reference to Fig. 3 It is clear that each of the two grip parts 20, 21 has a central grip portion 200, 210, by means of which a user can grip the respective grip part 20, 21. At each handle portion 200, 210 of each of the two handle portions 20, 21 adjoins the side an outer, presently closed trained bracket portion 201, 211 at. These outer strap sections 201, 211 are able to reduce the risk of injury to a user, in particular the risk of hand injuries, when the lifting device H in the area of at least one of the two handle parts 20, 21, for example, a contact with another object or a person experiences.

Darüber hinaus weist jedes der beiden Griffteile 20, 21 einen inneren, vorliegend ebenfalls geschlossen ausgebildeten Bügelabschnitt 202, 212 auf. Jeder der beiden inneren Bügelabschnitte 202, 212 schließt sich seitlich an den Griffabschnitt 200, 210 des jeweiligen Griffteils 20, 21 an. Zwischen jedem der inneren Bügelabschnitte 202, 212 und dem zugehörigen Griffabschnitt 200, 210 ist jeweils ein Aufnahmeraum 203, 213 ausgebildet, innerhalb dessen zum Beispiel zumindest eine Bedieneinheit, eine Anzeigeeinheit, eine kombinierte Bedien- und Anzeigeeinheit und/oder zumindest ein Ablageelement, angeordnet werden können/kann. In dem hier gezeigten Ausführungsbeispiel ist zudem an einer Außenseite des inneren Bügelabschnitts 202 des ersten Griffteils 20 eine Bedieneinheit 24 angebracht, mittels derer zum Beispiel die Hubbewegung des Anschlussmittels 12 für das Hebezeug gesteuert werden kann. Die Bedieneinheit 24 kann zum Beispiel berührungssensitiv ausgeführt sein. In einer bevorzugten Ausführungsform kann die Bedieneinheit 24 ein berührungssensitives Anzeigemittel umfassen, mittels dessen Bedieneingaben getätigt werden können und beispielsweise Informationen über ausgewählte Betriebsparameter der Hubvorrichtung H angezeigt werden können.In addition, each of the two handle parts 20, 21 has an inner, in the present case likewise closed, bracket section 202, 212. Each of the two inner bracket sections 202, 212 adjoins laterally against the grip section 200, 210 of the respective grip section 20, 21. Between each of the inner bracket portions 202, 212 and the associated handle portion 200, 210, respectively, a receiving space 203, 213 is formed within which, for example, at least one operating unit, a display unit, a combined control and display unit and / or at least one storage element, are arranged can. In the embodiment shown here, an operating unit 24 is also attached to an outer side of the inner bracket section 202 of the first handle part 20, by means of which, for example, the lifting movement of the connecting means 12 can be controlled for the hoist. The operating unit 24 can be designed, for example, touch-sensitive. In a preferred embodiment, the operating unit 24 comprise a touch-sensitive display means by means of which operator inputs can be made and, for example, information about selected operating parameters of the lifting device H can be displayed.

Die Hubvorrichtung H kann ferner ein weiteres Gehäuse 22 aufweisen, innerhalb dessen eine Anzeige- und/oder Steuerungseinrichtung zur Steuerung eines Funktionselements, wie zum Beispiel einer Greifvorrichtung, des Hebezeugs und eine zugehörige Bedieneinheit 23 untergebracht sind. Ebenso können ggf. Informationen angezeigt werden. Dieses Gehäuse 22 ist an dem Basisabschnitt 161 des Griffbügels 160 des Handhabungsmittels 16 angebracht, insbesondere an diesen angehängt. Da die Bedieneinheit 23 für die Steuerung des Funktionselements des Hebezeugs innerhalb des an dem Griffbügel 160 angebrachten Gehäuses 22 untergebracht ist, kann erschwert werden, dass das Funktionselement des Hebezeugs von einem Benutzer während der Fahrt der Hubvorrichtung H betätigt werden kann. Daraus ergibt sich eine höhere Betriebssicherheit der Hubvorrichtung H. Da das Handhabungsmittel 16 mit Hilfe des Haltemittels 17 relativ zu dem Mast 10 in seiner Höhe verstellt werden kann, wird zudem in vorteilhafter Weise erreicht, dass das an dem Griffbügel 160 des Handhabungsmittels 16 angebrachte Gehäuse 22 und die darin untergebrachte Bedieneinheit 23 unter ergonomischen Gesichtspunkten stets auf eine optimale, an die Körpergröße eines Nutzers der Hubvorrichtung H angepasste Höhe eingestellt werden kann.The lifting device H may further comprise a further housing 22, within which a display and / or control device for controlling a functional element, such as a gripping device, the hoist and an associated control unit 23 are housed. Likewise, if necessary, information can be displayed. This housing 22 is attached to the base portion 161 of the handle bracket 160 of the handling means 16, in particular attached to this. Since the operation unit 23 for controlling the operation member of the hoist is accommodated within the housing 22 attached to the handle bracket 160, it can be made difficult for the operation member of the hoist to be operated by a user while the hoist H is running. This results in a higher reliability of the lifting device H. Since the handling means 16 can be adjusted by means of the holding means 17 relative to the mast 10 in height, is also achieved in an advantageous manner that the attached to the handle 160 of the handling means 16 housing 22nd and the operating unit 23 accommodated therein can always be adjusted from an ergonomic point of view to an optimum height adapted to the height of a user of the lifting device H.

Unter Bezugnahme auf Fig. 9 bis 11 soll nachfolgend eine Hubvorrichtung H näher erläutert werden, die gemäß einem zweiten Ausführungsbeispiel der vorliegenden Erfindung ausgeführt ist. Der grundlegende Aufbau dieser Hubvorrichtung H unterscheidet sich vom ersten Ausführungsbeispiel in erster Linie dadurch, dass die Hubvorrichtung H drei nebeneinander angeordnete Masteinheiten 1a, 1 b, 1 c mit jeweils einem Mast 10a, 10b, 10c aufweist. Aus diesem Grund wurden in Fig. 9 bis 11 funktional identische Bauteilkomponenten der Hubvorrichtung H gemäß dem zweiten Ausführungsbeispiel mit denselben Bezugszeichen versehen, die bei der Beschreibung des ersten Ausführungsbeispiels verwendet wurden. Nachfolgend sollen in erster Linie nur die konstruktiven Änderungen gegenüber dem ersten Ausführungsbeispiel näher erläutert werden.With reference to Fig. 9 to 11 will now be explained in more detail a lifting device H, which is designed according to a second embodiment of the present invention. The basic structure of this lifting device H differs from the first embodiment primarily in that the lifting device H three juxtaposed mast units 1a, 1 b, 1 c, each with a mast 10 a, 10 b, 10 c. Because of this, were in Fig. 9 to 11 Functionally identical component components of the lifting device H according to the second embodiment provided with the same reference numerals that were used in the description of the first embodiment. In the following, only the design changes compared to the first embodiment will be explained in more detail in the first place.

Eine erste (mittlere) Masteinheit 1a der Hubvorrichtung H weist einen Mast 10a auf, der an einer diesem zugeordneten Mastfuß 11a angebracht ist, die ihrerseits an dem Querträger 5, der sich in Querrichtung zwischen den beiden Seitenteilen 3, 4 erstreckt, angebracht ist. An einer Rückseite des Mastes 10a der ersten Masteinheit 1a ist wiederum das Gehäuse 15 angebracht, innerhalb dessen die Steuerungseinrichtung zur Steuerung des Hubmotors der Hubvorrichtung H sowie ggf. der Akkumulator untergebracht sind.A first (middle) mast unit 1a of the lifting device H has a mast 10a attached to a mast foot 11a associated therewith, which in turn is attached to the cross member 5 extending transversely between the two side members 3,4. On a rear side of the mast 10a of the first mast unit 1a, in turn, the housing 15 is mounted, within which the control device for controlling the lifting motor of the lifting device H and possibly the accumulator are housed.
