- a person who wishes to ascend the structure is relieved of the weight load by the safety rope.
- the person can easily be secured by using a conventional fall-arrest device or fall-arrest device, also called a "fall arrester" for a short time, on the safety rope after it has been put on, and when it ascends at each Hanging loop through which the safety rope extends, the safety rope is briefly posted (or generally released) from this hanger, so as to allow passage of the fall arrester. Immediately thereafter, the safety rope is immediately coupled back into the hanger, so as to ensure the desired safety. In the event of a fall, such a fall arrest device immediately, without drop height, stops this fall and thus the person, who is therefore hardly exposed to physical strain in such a fall and learns in comparison to the previous systems, a gentle catch.
- a mast 1 is schematically illustrated in view.
- This mast 1 consists in a conventional manner from a truss structure and contains For example, boom 2.
- risers 4 are provided on both sides laterally to allow a person to climb the corner post 3 and thus the pole 1.
- the risers 4 have at their freely projecting ends Fig. 1 unspecified hanger elements, with a training of the risers 4 as safety risers as in EP 577 587 B1 is disclosed.
- Such a design of the risers as safety risers with helical hooks is from the Fig. 2 and 3 but also out Fig.
- Fig. 1 the safety rope 6 is also shown in already wound state, it can be seen that the safety rope 6 from the ground, from a rope bag 7 attached there, up to a deflection 8 at the upper end of the line mast 1 and from there again down to near the ground where it is fixed extends.
- Fig. 1 to 3 is also schematically a base 9 of the line mast 1 recognizable, which serves as a foundation for supporting the actual line mast 1, ie of its truss structure, on the ground.
- Fig. 2 runs a comparatively thin, light trailing rope 10 at the corner post 3 of the line mast 1 from a fixing point 11 near the ground upwards, by hooking 5 of risers 4, to the upper deflector 8 and from there again down to a roll-up and fixing device 12 shown only schematically.
- the deflection device 8 is in accordance with in this example Fig. 2 formed by a single rubberized, a relatively large diameter pulley 13. This deflecting roller 13 or generally the deflecting device 8 is on the upper side a weather protection 8 'assigned so as to protect the guide roller 13 against rain or snow.
- the leader 10 is in the in Fig. 2 arrangement shown arranged permanently on the pole 1.
- a closable cover or a lockable housing 14 for example consisting of two in each case 90 ° apart pivotable cup-shaped housing parts 14A, 14B, provided.
- Fig. 3 For example, these two cover parts 14A, 14B are illustrated in the unfolded, downwardly pivoted position (lying on the base 9).
- a drive means 16 is provided, to which the roller 15 belongs, and which has a motor 17, see. also Fig. 7 .
- This motor 17 is preferably an electric motor, which is powered by a battery 18 with energy.
- the motor 17 drives via a reversing gear not illustrated in more detail and via a shaft 19 to the pre-rope pulley 15;
- the motor 17 can drive a middle roller 20 of a roller device or a roller apparatus 21 for the safety cable 6 via a shaft 19 ', cf.
- the safety rope 6 is thereby removed from the rope bag 7 engaged with the corner post 3 of the line mast 1, as in addition to Fig. 3 also clearer in Fig. 5 is shown.
- the rolling device 21 has two further rollers 22 (upper roller) and 23 (lower roller) to to ensure a total safe guidance of the safety rope 6 when mounting as well as when pulling.
- the safety rope 6 may have, for example, a diameter of 10 mm to 15 mm and more, whereas the trailing rope 10 may be, for example, a plastic rope with a diameter of 3 mm.
- rollers 20, 22 and 23 are as well as the roller 15 for the Vorseil in a conventional manner, not shown in detail, rotatably mounted on the corner post 3 of the line mast 1. It is also conceivable to arrange the bearing for the middle roller 20 of the rolling device 21 sprung, as in Fig. 5 is indicated schematically at 24.

- the safety cable 6 is connected or coupled, and on this in Fig. 3 at VI with a circle schematically illustrated connection then the safety rope 6 is raised by means of the pre-cable 10, wherein previously the foresail 10 with the lower end of the downward run 10B, previously from the fixing roller 12 has been solved, was attached to the roller 15 in a conventional manner, so that the Vorseil 10 can then be wound on this roller 15, when driven by the motor 17.
- the foresail 10 is thereby completely wound, ie the safety rope 6 is pulled up to the deflection device 8 and pulled from there back down to the roller 15 and fixed there in a manner not shown in detail. Then a safe climb on the pole 1 is possible.
- a per se conventional fall arrester 27 can be used, as it is in Fig. 8 is shown schematically; this fall arrester 27 is connected via a short connection 28 with a seat belt 29 of the respective person, as also from Fig. 8 is apparent. Since the safety rope 6 is firmly anchored in the mounted state on the pole 1, the fall height is practically zero in the event of a fall of a person, so that even a small amount of energy or low forces act on the person.
- the helical hanger eyes or lug elements 5 not only allow an extremely simple unhooking and unhooking of the safety rope 6 (or before hanging the foreline 10) on the open coil, but serve as mentioned as a footing and Abbreêt for the risers. 4

- the drive device 16 is preferably mounted only when needed on the power pole 1 in the lower area to the safety rope 6 from the cable bag 7, which is then also placed in this case, only with the help of the Vorseils 10, on the roller 15th is rolled up, wind up, finally, an arrangement with the safety rope 6 as in Fig. 1 and 9 shown to reach.
- the two free ends of the foresail 10 are in a deeper area, approximately at a height between 1 m and 1.5 m, so that access to these Vorseil-ends after Opening the cover 14 without any lift aids is possible.
- Access to the two ends of the leader 10 only by means of a ladder or the like. Possible to thereby provide increased security against unauthorized access.
- a modified deflecting device 8 is shown for the present security system, wherein Fig. 10a a view Fig. 10b a top view and Fig. 10c a side view illustrated. It is off Fig. 10b Also, the attachment to a corner post 3 of a not shown in detail wire mast 1 can be seen, with a per se conventional clamping system 40 for fixing a holder 41 for the deflection 8 is shown.

- Each of these guide pins 42 is in a vertical longitudinal slot 43 (s. Fig. 10a ) mounted vertically displaceable, and against one only very schematically in Fig. 10c
- the two guide pins 42 according to arrow 45 in Fig.
- the guide pins 42 thus form camber-damping elements and pressure limiter.
- the guide pins 42 may be coated with plastic, so as to make the cable guide as frictionless as possible.
- a rotatable roller instead of this plastic sheath, a rotatable roller (42 'in Fig. 11b ) be provided.
- Fig. 11 is in the partial presentations Fig. 11a (View), 11b (top view) and 11c (side view) of a deflection 8 according to Fig. 10 very similar deflection shown, extending from the deflection 8 according to Fig. 10 basically differs only in that instead of the safety riser 4 with end-sided helical hanger 5 now a simple eyebolt 4 'is attached to the holder 41.
- the holder 41 can thereby as based on the Fig. 10 already described be attached to a corner post 3 by means of a clamping system 40.
- the ring pin 4 ' has at its freely projecting end a one-piece, formed by bending closed ring, through the the safety rope 6 (and previously the Vorseil 10, see, for example Fig. 2 and 3 ) is pulled.
- the guide pins 42 are corresponding Fig. 10 trained and stored, so that a new description and a more accurate representation may be unnecessary.
- Fig. 12 is, again in corresponding partial views, namely view ( Fig. 12a ), Top view ( Fig. 12b ) and side view ( Fig. 12c ), a particularly simple deflection device 8, which is formed by a mere safety riser 4 with end-side helix as Einhhurinate 5 for the safety rope 6 (and of course for the front mounted cable 10). Side guide pins or rollers are not provided. Otherwise, the embodiment corresponds to the deflection device 8 according to FIG Fig. 12 according to those Fig. 10 and 11 , so that a new description of this can be unnecessary.

Diese Sicherheits-Steigsprossen haben sich in der Praxis bestens bewährt, jedoch ist bei diesem System ebenso wie bei ähnlichen Systemen, etwa mit Karabinern an den Steigsprossen zum Einhängen des Sicherungsseils, von Nachteil, dass die den Mast besteigende Person das Sicherungsseil beim Aufsteigen mit sich tragen und sukzessive in die jeweiligen Einhängösen oder dergl. einhängen muss. Dabei ist zu beachten, dass die Masthöhe durchaus beispielsweise 50 m und mehr betragen kann, sodass das Gewicht eines so langen Sicherungsseils außerordentlich hoch ist. Darüber hinaus ist im Fall eines Abrutschens und Sturzes der aufsteigenden Person auch eine gewisse Fallhöhe - entsprechend dem Abstand zur nächst-unteren Einhängöse - gegeben, was durchaus eine wesentliche Belastung der abstürzenden Person trotz Sicherung bedeuten kann. Dieses Risiko ist insbesondere auch beim jeweiligen Einhängvorgang beim Aufsteigen, einer zusätzlich anfallenden Tätigkeit, gegeben.These safety risers have proven themselves in practice, but is in this system as well as similar systems, such as with carabiners on the risers for hanging the safety rope, disadvantage that the person ascending the mast person carry the safety rope with the ascent and successively in the respective suspension eyes or the like. Hang. It should be noted that the mast height may be, for example, 50 m and more, so that the weight of such a long safety rope is extremely high. In addition, in the event of slippage and fall of the ascending person also a certain drop height - in accordance with the distance to the next-lower hanger - given, which may well mean a significant burden on the person falling despite security. This risk is in particular also given the respective Einhängvorgang when ascending, an additional incidental activity.
Es ist nun Ziel der vorliegenden Erfindung, hier Abhilfe zu schaffen und ein Sicherungssystem vorzusehen, bei dem für eine aufsteigende Person nicht nur die Gewichtsbelastung durch ein mitzunehmendes Sicherungsseil entfallen kann, sondern insgesamt die Tätigkeiten erleichtert werden. Die Erfindung sucht dabei auch eine zweckmäßige Lösung, bei der eine bleibende Anbringung eines Sicherungsseils am jeweiligen Leitungsmast oder dergl. Bauwerk vermieden wird, um so ein Entwenden derartiger doch relativ aufwendiger und kostspieliger Sicherungsseile ebenso wie das Anbringen von aufwendigen Sicherungsseilen in großer Zahl, an allen Leitungsmasten oder dergl. Bauwerken, in einer bleibenden Form zu vermeiden. Andererseits soll ein - vergleichsweise leichtes und preiswertes - Vorseil am Bauwerk verbleiben können, wobei ein unbefugtes Abnehmen dieses Vorseils nach Möglichkeit verhindert werden soll.It is now an object of the present invention to remedy this situation and to provide a security system in which not only the weight load can be omitted by a safety rope to be taken for a rising person, but overall the activities are facilitated. The invention also seeks an expedient solution in which a permanent attachment of a safety rope on the respective pole or the like. Construction is avoided, so as to steal such but relatively expensive and costly safety ropes as well as the attachment of complex safety ropes in large numbers, at all Pylons or the like. Structures to avoid in a permanent form. On the other hand, a - relatively easy and inexpensive - Vorseil can remain on the building, with an unauthorized removal of this Vorseils should be prevented if possible.

In entsprechender Weise ist das erfindungsgemäße Verfahren durch die in Anspruch 14 definierten Merkmale gegeben.In a corresponding manner, the method according to the invention is given by the features defined in
Weiters sieht die Erfindung einen Leitungsmast mit dem erfindungsgemäßen Sicherungssystem vor, mit Steigsprossen an einem Mast-Eckstiel, die an den frei auskragenden Enden Einhängösen aufweisen.Furthermore, the invention provides a pole with the security system according to the invention before, with risers on a mast corner handle, which have hooks on the freely projecting ends.
Vorteilhafte Ausführungsformen und Weiterbildungen sind in den abhängigen Ansprüchen angegeben.Advantageous embodiments and further developments are specified in the dependent claims.
Beim vorliegenden Sicherungssystem wird ein vergleichsweise dünnes, einfaches, kostengünstiges Vorseil, z.B. ein Kunststoffseil, bleibend am Bauwerk, insbesondere Leitungsmast oder dergl., angebracht, wobei es durch Ösenelemente bzw. Einhängösen hindurchgeführt wird. Dieses Vorseil weist eine derartige Länge auf, dass es sich im angebrachten Zustand am Bauwerk, insbesondere Leitungsmast oder dergl., in einem Aufwärts-Trum aufwärts bis zu einer oberen Umlenkstelle und von dort in einem Abwärts--Trum wieder nach unten erstreckt. An der Umlenkstelle wird eine Umlenkeinrichtung für das Vorseil bzw. Sicherungsseil angebracht. Das Vorseil hat im Aufwärts-Trum ein freies unteres Ende, das im Bedarfsfall mit einem herantransportierten Sicherungsseil verbunden wird, wozu entsprechende Verbindungselemente, wie insbesondere Haken und Schlaufen, vorgesehen sein können. Das andere (vordere) Ende des Vorseils, das das untere Ende des Abwärts-Trums ist, wird im unteren Bereich des Bauwerks bzw. Leitungsmasts oder dergl. fixiert.In the present security system, a comparatively thin, simple, low-cost overhead rope, e.g. a plastic rope, permanently attached to the structure, in particular pylon or the like., Attached, wherein it is passed through loop elements or Einhängösen. This pre-rope has such a length that it extends in the attached state on the structure, in particular pylon or the like. In an upward Trum up to an upper diverter and from there in a downward Trum back down. At the point of deflection, a deflection device for the pre-cable or safety rope is attached. The foresail has a free lower end in the upward strand, which is connected in case of need with a transported safety rope, for which purpose connection elements, such as in particular hooks and loops, can be provided. The other (front) end of the pre-line, which is the lower end of the down-run, is fixed in the lower part of the structure or line mast or the like.
Demzufolge kann das jeweilige Sicherungsseil im Bedarfsfall antransportiert und mit Hilfe des Vorseils auf das Bauwerk bzw. den Leitungsmast, Handymast oder dergl. wie gewünscht aufgezogen werden. Zu diesem Zweck ist eine Antriebseinrichtung mit einer Rolle für das Vorseil vorgesehen, die das Vorseil beginnend mit dem unteren Ende von dessen Abwärts-Trum im Betrieb aufrollt, um so auf der anderen Seite mit Hilfe des Aufwärts-Trums des Vorseils das Sicherungsseil hochzuziehen und über die Umlenkeinrichtung zu ziehen. Ein wesentlicher Vorteil dieses Systems ist, dass das Sicherungsteil mit Hilfe des Vorseils automatisch durch die Ösenelemente (Einhängösen) gezogen wird, so dass sich ein nachträgliches gesondertes Fixieren des Seils in den Ösenelementen erübrigt.Accordingly, the respective safety rope can be transported in case of need and reared with the help of the Vorseils on the building or the mast, mobile mast or the like. As desired. For this purpose, a drive means is provided with a role for the Vorseil, which rolls up the Vorseil starting with the lower end of the downstream Trum in operation, so as to pull up on the other side by means of the upward run of the Vorseils the safety rope and over to pull the diverter. An essential advantage of this system is that the securing part is automatically pulled by means of the pre-cable through the eyelet elements (suspension eyes), so that a subsequent separate fixing of the rope in the eyelet elements is unnecessary.
Die beiden unteren Enden des Vorseils können, wenn dieses am Bauwerk bzw. Leitungsmast oder dergl. angebracht wurde, durch eine insbesondere verschließbare Abdeckung vor einem unbefugten Zugriff gesichert werden.The two lower ends of the roughing rope, if this has been attached to the building or pylon or the like. Be secured by a particular lockable cover against unauthorized access.
Als Umlenkeinrichtung können beispielsweise bogenförmige Gleitelemente oder aber - bevorzugt - eine Umlenkrolle, oder aber mehrere Umlenkrollen hintereinander vorgesehen werden; weiters kann die Umlenkeinrichtung einfach einen Bolzen mit einem daran vorgesehenen Ösenelement aufweisen, wobei der Bolzen mit Vorteil durch eine Steigsprosse mit wendelförmigen Ösenelementen gebildet ist. Vorzugsweise ist beidseits des Bolzens jeweils eine Führungsrolle oder ein Führungsbolzen für das Sicherungsseil angebracht ist, wobei es weiters günstig ist, wenn die Führungsrollen oder -bolzen in Längsschlitzen in einem am Bauwerk angebrachten Halter verschiebbar gelagert sind.As a deflection device, for example, arcuate sliding elements or - preferably - a deflection roller, or a plurality of deflection rollers are provided one behind the other; Furthermore, the deflection device can simply have a bolt with an eyelet element provided thereon, wherein the bolt is advantageously formed by a climbing rung with helical eyelet elements. Preferably, a guide roller or a guide pin for the safety rope is mounted on both sides of the bolt, wherein it is further favorable if the guide rollers or bolts are slidably mounted in longitudinal slots in a holder attached to the structure.
Als Antriebseinrichtung kann beispielsweise im einfachen Fall eine Handkurbel dienen, die mit der Rolle für das Vorseil gekoppelt ist, vorzugsweise wird jedoch ein Motor, insbesondere ein Elektromotor vorgesehen.As a drive device, for example, in the simple case serve a hand crank, which is coupled to the roller for the Vorseil, but preferably a motor, in particular an electric motor is provided.
Damit nach dem Absteigen der Person vom Bauwerk bzw. Leitungsmast oder dergl. das Sicherungsseil wieder eingeholt werden kann, ist es zweckmäßig, das Vorseil bzw. das Sicherungsseil in der umgekehrten Richtung anzutreiben, und demgemäß kann die Antriebseinrichtung gegebenenfalls ein dem Motor nachgeschaltetes Wendegetriebe aufweisen.Thus, after the person descends from the structure or pylon or the like. The safety rope can be retrieved, it is expedient to drive the Vorseil or safety rope in the reverse direction, and accordingly, the drive means may optionally have a reversing gear downstream of the engine.
Im Fall eines Elektromotors für die Antriebseinrichtung, wie dieser besonders bevorzugt wird, kann eine Batterie zur Energieversorgung dieses Elektromotors vorgesehen sein. Dabei ist es auch denkbar, eine aufladbare Batterie, einen Akkumulator, vorzusehen, wobei auch eine Photovoltaikanlage zur Speisung dieser aufladbaren Batterie im Bereich des Bauwerks bzw. Leitungsmasts oder dergl. vorgesehen werden kann.In the case of an electric motor for the drive device, as this is particularly preferred, a battery for powering this electric motor can be provided. It is also conceivable to provide a rechargeable battery, an accumulator, wherein a photovoltaic system for feeding this rechargeable battery in the area of the building or line mast or the like. Can be provided.
Um beim Einholen des Sicherungsseils dieses in Abwärtsrichtung zwangsweise anzutreiben, kann auch eine Rolleneinrichtung vorgesehen sein, die bevorzugt mit derselben Antriebseinrichtung gekoppelt ist, mit der die Antriebs- und Aufwickel-Rolle für das Vorseil verbunden ist.In order to forcibly drive in the downward direction when the safety rope is being retrieved, a roller device may also be provided, which is preferably coupled to the same drive device with which the drive and take-up roller for the pre-cable is connected.
Zur Speicherung des Sicherungsseils kann ein Seilsack vorgesehen werden, der den Transport des Sicherungsseils zu und von dem Bauwerk in einer kompakten Einheit ermöglicht, und der gegebenenfalls auch in einer versperrbaren Einhausung am Bauwerk - zumindest vorübergehend - gelagert werden kann.For storing the safety rope, a cable bag can be provided be, which allows the transport of the safety rope to and from the building in a compact unit, and if necessary, in a lockable housing on the building - at least temporarily - can be stored.
Zur Sicherung der Vorseil-Enden sowie gegebenenfalls der Antriebseinrichtung, wenn diese an Ort und Stelle verbleiben soll, kann beispielsweise ein öffenbares Gehäuse, insbesondere mit abwärts klappbaren Gehäuseteilen, am Bauwerk bzw. Leitungsmast angebracht werden, um so im geschlossenen, versperrten Zustand die Vorseil-Rolle sowie gegebenenfalls die Antriebseinrichtung, eventuell samt der Sicherungsseil-Rolleneinrichtung, gegen einen unbefugten Zugriff zu sichern.To secure the pre-cable ends and possibly the drive device, if this is to remain in place, for example, an openable housing, in particular with downwardly foldable housing parts, be attached to the structure or mast, so as in the closed, locked state the pre-cable Roll and possibly the drive device, possibly together with the safety rope roller device to secure against unauthorized access.
Die Erfindung betrifft auch einen (Strom-)Leitungsmast mit einem Sicherungssystem wie vorstehend angegeben. Dabei weist dieser Leitungsmast Steigsprossen an einem Mast-Eckstiel auf, die an den frei auskragenden Enden Einhängösen aufweisen. Weiters ist an diesem Leitungsmast bleibend ein Vorseil wie vorstehend angegeben, mit einem Aufwärts-Trum und einem Abwärts-Trum, angebracht, wobei das Vorseil sich über eine obere Umlenkeinrichtung erstreckt, die am Leitungsmast oben angebracht ist. Im unteren Bereich des Leitungsmasts ist eine Antriebseinrichtung mit einer Antriebs- und Aufwickel-Rolle für das Vorseil angeordnet, wobei das untere Ende des Abwärts-Trums des Vorseils mit dieser Rolle verbunden wird, sodass beim Drehen dieser Rolle das Vorseil auf dieser Rolle aufgewickelt und dabei mit dem Aufwärts-Trum hochgezogen werden kann. Das Vorseil weist an seinem freien Ende am Aufwärts-Trum bevorzugt ein Verbindungselement in Form eines Hakens auf, der mit einer Schlaufe am Ende des Sicherungsseils zusammenwirkt, um so das Sicherungsseil im Bedarfsfall auf den Leitungsmast aufziehen zu können.The invention also relates to a (power) pole with a safety system as indicated above. In this case, this line mast climbing rungs on a mast corner handle, which have hooks on the freely projecting ends. Furthermore, a pre-rope as indicated above, with an up-run and a down-run, is attached to this mast permanently, wherein the pre-rope extends over an upper deflector, which is mounted on the top of the pole. In the lower part of the line mast, there is a drive means with a drive and take-up roll for the fore rope, the lower end of the downtrend of the fore rope being connected to this roll, so that when this roll is turned, the fore rope is wound on this roll and thereby can be pulled upwards. The pre-cable has at its free end on the upward strand preferably on a connecting element in the form of a hook, which cooperates with a loop at the end of the safety rope, so as to raise the safety rope on demand on the pole.
Mit dem vorliegenden Sicherungssystems ist eine Person, die auf das Bauwerk, wie etwa einen Leitungsmast, aufsteigen will, von der Gewichtsbelastung durch das Sicherungsseil befreit. Die Person kann dabei einfach unter Benutzung eines herkömmlichen Absturz-Sicherungsgeräts oder Sturzfanggeräts, auch kurz (mitlaufendes) "Auffanggerät" genannt, am Sicherungsseil nach dessen Aufziehen gesichert werden, wobei beim Aufsteigen bei jeden Einhängöse, durch die sich das Sicherungsseil erstreckt, das Sicherungsseil kurz aus dieser Einhängöse ausgehängt (bzw. allgemein gelöst) wird, um so ein Passieren des Auffanggeräts zu ermöglichen. Unmittelbar danach wird das Sicherungsseil sofort wieder in die Einhängöse eingekoppelt, um so die gewünschte Sicherheit zu gewährleisten. Im Fall eines Sturzes stoppt ein derartiges Auffanggerät unmittelbar, ohne Fallhöhe, diesen Sturz und damit die Person, die daher bei einem derartigen Sturz kaum einer körperlichen Belastung ausgesetzt wird und im Vergleich zu den früheren Systemen ein schonendes Auffangen erfährt.With the present security system, a person who wishes to ascend the structure, such as a pylon, is relieved of the weight load by the safety rope. The person can easily be secured by using a conventional fall-arrest device or fall-arrest device, also called a "fall arrester" for a short time, on the safety rope after it has been put on, and when it ascends at each Hanging loop through which the safety rope extends, the safety rope is briefly posted (or generally released) from this hanger, so as to allow passage of the fall arrester. Immediately thereafter, the safety rope is immediately coupled back into the hanger, so as to ensure the desired safety. In the event of a fall, such a fall arrest device immediately, without drop height, stops this fall and thus the person, who is therefore hardly exposed to physical strain in such a fall and learns in comparison to the previous systems, a gentle catch.
