In Fig. 1 bezeichnet die Hinweisziffer 1 den Teleskopausleger eines an sich bekannten, selbstfahrenden Pneukrans, an dessen Enden.die beiden Umlenkrollen 2 und 3 für das nicht dargestellte Kranseil angebracht sind. Die den Kranausleger 1 seitlich überragenden Drehachsen 4 der Um- lenkrollen 2 und 3 sind oben und unten abgeflacht und mit Bohrungen 6 zur Aufnahme von Steckbolzen 7 durchsetzt.In Fig. 1, reference numeral 1 denotes the telescopic boom of a self-propelled pneumatic crane known per se, at the ends of which the two deflection rollers 2 and 3 for the crane rope (not shown) are attached. The axes of rotation 4 of the guide rollers 2 and 3 projecting laterally beyond the crane boom 1 are flattened at the top and bottom and penetrated with bores 6 for receiving plug pins 7.

Ein Adapter 8 weist zwei übereinander, angeordnete Armpaare. 9 sowie einen Tragrahmen 10 auf. Die Arme jedes Armpaares greifen zu gegenüberliegenden Seiten am Auslegerende vorabei und über- bzw. untergreifeh dabei mit ihren gegabelten Enden die seitlich herausragenden Enden der Drehachsen 4 der Umlenkrollen 2 und 3 und sind mit den Boh- rungen 6 entsprechenden, koachsialen Bohrungen versehen. Durch in die Bohrungen eingeschobene Steckbolzen 7 ist der ''Adapter 8 am Ausleger 1 befestigt. Werden die Steckbolzen 7 an einer Auslegerseite herausgezogen, so kann der Adap- . ter 8 um eine erste Schwenkachse 5, gebildet durch die Steckbolzen 7 der anderen Auslegerseite, wie ein Türblatt nach hinten 'umgeschwenkt werden. Am oberen Ende des Tragrahmens 10 sind zwei koachsial ausgerichtete Rohrschellenlager 11 angeordnet, die der Aufnahme eines Rohrstückes 12 dienen. Jedes Rohrschellenlager 11 weist eine mit den Tragrahmen 10 fest verbundene untere Halbschale sowie eine obere, wegschwenkbare Halbschale auf. Am unteren Ende des Tragrahmena 10 sind zwei koaohsial ausgerichtete Rohrschellenlager 13 angeordnet, die der Aufnahme eines Rohrstückes 14 dienen. Die Rohrstücke 12 und 14 sind durch eine Strebe 15 fest miteinander verbunden, an der eine obere und eine untere Gelenkstrebe 16 bzw. 17 angelenkt sind. Die anderen Enden der Gelenkstreben 16 und 17 sind an einem Schwenklagergehäuse 18 angelenkt, das eine zweite Schwenkachse 19 bildet. Im Schwenklagergehäuse 18 ist eine Schwenkwelle 20 drehbar gelagert, welche oben und unten fest mit Laschen 21 verbunden ist. Mit den Laschen 21 fest verbunden ist weiter ein Rahmen 22, an dem eine Arbeitsplattform 23 befestigt ist. Die Arbeitsplattform 23 ist vom Rahmen 22 und von zwei Seitengeländern 24 und einem Frontgeländer 25 eingezäunt. Die Seitengeländer 24 sind (vql. Fig. 3 bis 5) bei 26 lösbar mit dem Frontgeländer 25 verbunden und am Rahmen 22 angelenkt, derart, dass sie gegen den Rahmen 22 und in dessen, zur Achse 19 parallele Ebene schwenkbar sind. Das Frontgeländer 25 ist bei 27 an der Arbeitsplatt- form 23 angelenkt und kann, wie die Fig. 4 und 5 zeigen, gegen die Arbeitsplattform 23 umgelegt werden. Die Arbeits- plattform 23 ihrerseits ist bei 28 gelenkig mit dem Rahmen 22 verbunden und kann zusammen mit dem Frontgeländer 25 in eine zum Rahmen 22 parallele Lage geschwenkt werden (Fig. 5), Sind die Geländer 24 und 25 und die Arbeitsplattform 23 in der beschriebenen Weise zusammengeklappt, kann der Rahmen 22 um die Achse 19 um 90° verschwenkt werden, so dass er parallel zu den Gelenkstreben 16 und 17 liegt. Werden die Steckbolzen 7 auf einer Seite des Auslegers 1 herausgezogen, können die Gelenkstreben 16 und 17 zusammen mit dem Rahmen 22 nach hinten um die erste Achse 5 in eine zum. Ausleger 1 parallele Lage verschwenkt werden, wie dies Fig. 6 zeigt. In dieser Transportstellung der Arbeitsplattform 23 lässt sich diese ohne besonderen Massnahmen am Ausleger 1 transportieren.An adapter 8 has two pairs of arms arranged one above the other. 9 and a support frame 10. The arms of each pair of arms reach on opposite sides at the end of the boom and, with their forked ends, overlap or underneath, the laterally protruding ends of the axes of rotation 4 of the deflection rollers 2 and 3 and are provided with the corresponding coaxial holes 6. The '' adapter 8 is fastened to the boom 1 by means of plug pins 7 inserted into the bores. If the socket pins 7 are pulled out on one side of the boom, the adapter can. ter 8 about a first pivot axis 5, formed by the socket pins 7 of the other side of the boom, like a door leaf can be swung backwards. At the upper end of the support frame 10, two coaxially aligned pipe clamp bearings 11 are arranged, which serve to receive a pipe section 12. Each pipe clamp bearing 11 has a lower half shell firmly connected to the support frame 10 and an upper half shell which can be pivoted away. At the lower end of the support frame 10 are two coaxial pipe clamps camp 13 arranged, which serve to accommodate a pipe section 14. The pipe sections 12 and 14 are firmly connected to one another by a strut 15 to which an upper and a lower articulated strut 16 and 17 are articulated. The other ends of the articulated struts 16 and 17 are articulated on a pivot bearing housing 18, which forms a second pivot axis 19. In the pivot bearing housing 18, a pivot shaft 20 is rotatably mounted, which is firmly connected to tabs 21 at the top and bottom. A frame 22, to which a work platform 23 is fastened, is also firmly connected to the tabs 21. The work platform 23 is fenced by the frame 22 and by two side railings 24 and a front railing 25. The side railings 24 (see FIGS. 3 to 5) are releasably connected at 26 to the front railing 25 and articulated on the frame 22 such that they can be pivoted against the frame 22 and in its plane parallel to the axis 19. The front railing 25 is articulated on the work platform 23 at 27 and, as shown in FIGS. 4 and 5, can be folded against the work platform 23. The work platform 23 in turn is articulated to the frame 22 at 28 and can be pivoted together with the front railing 25 into a position parallel to the frame 22 (FIG. 5), if the railings 24 and 25 and the work platform 23 are described in FIG When folded together, the frame 22 can be pivoted through 90 ° about the axis 19, so that it lies parallel to the articulated struts 16 and 17. If the socket pins 7 are pulled out on one side of the boom 1, the joint struts 16 and 17 can be put together with the frame 22 to the rear about the first axis 5 in a. Boom 1 parallel position can be pivoted, as shown in FIG. 6. In this transport position of the working platform 23, it can be transported on the boom 1 without any special measures.

Die beiden Gelenkstreben 16 und 17 sind gelenkig durch eine Qüerstrebe 29 verbunden, welche die obere Gelenkstrebe 17 in zwei Teile teilt, von denen der eine Teil 30 teleskopartig längenverstellbar ist und aus einer hydraulischen Zylinderkolbeneinheit 30 besteht. Durch eine Längenverstellung des Gelenkstrebenteils 30 kann die Neigung der Arbeitsplattform 23 verändert werden. Durch eine an der Strebe 15 einerseits und an der Gelenkstrebe 16 anders eits angreifende hydraulische Zylinderkolbeneinheit kann die Neigung der Gelenkstreben 16 und 17 verstellt werden. Durch eine Betätigung der Zylinderkolbeneinheiten 30 und 31 kann (bei vollständig eingefahrenem Kranausleger 1) die Arbeitsplattform 23 in horizontaler Ausrichtung bis auf den Boden abgesenkt werden, wodurch das Betreten der Arbeiteplattform 23 durch eine Arbeitsequipe erleichtert wird.The two hinge struts 16 and 17 are connected in an articulated manner by a cross strut 29 which divides the upper hinge strut 17 into two parts, one part 30 of which is telescopically adjustable in length and consists of a hydraulic cylinder piston unit 30. The inclination of the work platform 23 can be changed by adjusting the length of the articulated strut part 30. The inclination of the articulated struts 16 and 17 can be adjusted by means of a hydraulic cylinder-piston unit which acts on the strut 15 on the one hand and on the articulated strut 16 in another way. By actuating the cylinder piston units 30 and 31 (with the crane boom 1 fully retracted), the work platform 23 can be lowered to the floor in a horizontal orientation, which makes it easier for a work trail to enter the work platform 23.

Wie Fig. 7 zeigt, sind bei den beiden oberen Rohrschellenlagern 11 die festen Lagerschaltenhälften liegend angeordnet, wogegen die festen Lagerschalenhälften 33 der unteren Rohrschellenlager 13 stehend angeordnet sind. Dadurch kann die Arbeitsplattform 23 in einfacher Weise am Adapter 8 befestigt werden, indem bei leicht angehobener Arbeitsplattform (Fig. 7) zuerst das obere Rohrstück 12 in die liegenden, festen Lagerschalenhälften 32 eingelegt und alsdann der ganze Träger nach unten geschwenkt wird, bis das Rohrstück 14 in den unteren, festen Lagerschalenhälften 33 liegt. Danach können die beweglichen Lagerechalenhälften geschlossen und mit den festen Lagerschalenhälften verschraubt werden.As shown in FIG. 7, in the two upper pipe clamp bearings 11 the fixed bearing shell halves are arranged horizontally, whereas the fixed bearing shell halves 33 of the lower pipe clamp bearings 13 are arranged in an upright position. As a result, the working platform 23 can be attached to the adapter 8 in a simple manner, by lifting it slightly Working platform (Fig. 7) first the upper pipe section 12 is placed in the lying, fixed bearing shell halves 32 and then the entire support is pivoted down until the pipe section 14 lies in the lower, fixed bearing shell halves 33. Then the movable halves of the storage rack can be closed and screwed to the fixed halves of the bearing shell.

Beim Ausführungsbeispiel nach Fig. 8 bis 11 sind . gleiche oder aequivalente Teile mit gleichen Hinweisziffern versehen.8 to 11 are in the embodiment. Identical or equivalent parts with the same reference numbers.

Bei diesem Ausführungsbeispiel sind die Seitengeländer 24' bei 26' schwenkbar um eine Achse am Frontgeländer 25' angelenkt und am freien Ende durch einen Steckstift 35 mit dem Rahmen 22' fest verriegelbar, wobei der Steckstift durch entsprechend koachsiale Oesen am Seitengeländer 24 und am Rahmen 22' gesteckt wird. Das Seitengeländer 24' kann um die Achse 26' gegen das Frontgeländer 25' verschwenkt werden, wobei die Schwenkachse '26' soweit gegenüber der Ebene des Frontgeländers 25' versetzt ist, dass sich das umgeschwenkte Seitengeländer 24' flächig gegen das Frontgeländer 25' anlegt, d.h., mit seiner Innenseite auf die Innenseite des Frontgeländers 25' zu liegen kommt. Sind nach dem Herausziehen der Stifte 35 die beiden Seitengeländer 24' gegen das Frontgeländer 25' geschwenkt wor-den, kann das letztere, zusammen mit den ersteren um die Achse 27'-verschwenkt werden, wobei deren Abstand zur Arbeitsplattform.23 so gewählt ist, dass die Seitengeländer 24' mit ihrer Aussenseite gleichmässig auf der Plattformoberseite aufliegen, so dass sich die Arbeitsplattform 23', die Seitengeländer 24' und das Frontgeländer 25' bei paralleler Ausrichtung gegenseitig berühren. Danach wird die Arbeitsplattform'23' um 90° um die Achse 37 gegen den Rahmen 22' verschwenkt, wobei die Versetzung der Achse 37 wiederum derart gewählt ist, dass das Frontgeländer 25' mit seiner Aussenseite parallel an den Rahmen 22' zu liegen kommt. Beim Hochklappen der Arbeitsplattform 23' werden zwei klappbare Tragstreben gleichzeitig zusammengeklappt. Diese sind mit einem ihrer Enden am Rahmen 22' und mit dem anderen an der Arbeitsplattform 23' angelenkt und weisen in der Mitte ein Knickgelenk auf. Beim Hochklappen der Arbeitsplattform 23' kommen die Streben 38' seitlich neben den Rahmen 22' zu liegen.In this exemplary embodiment, the side railings 24 'are pivoted at 26' about an axis on the front railing 25 'and can be firmly locked at the free end by a pin 35 to the frame 22', the pin being correspondingly coaxially eyelets on the side rail 24 and on the frame 22 'is stuck. The side railing 24 'can be pivoted about the axis 26' against the front railing 25 ', the pivot axis' 26 'being offset so far from the plane of the front railing 25' that the pivoted side railing 24 'lies flat against the front railing 25', that is, its inside comes to lie on the inside of the front railing 25 '. If the two side railings 24 'have been pivoted against the front railing 25' after the pins 35 have been pulled out, the latter, together with the former, can be pivoted about the axis 27 ', their distance from the working platform. 23 being selected such that that the side railings 24 'lie evenly on the upper side of the platform with its outer side, so that the working platform 23', the side railings 24 'and the front railing 25' touch one another in parallel alignment. Thereafter, the working platform '23' is pivoted 90 ° about the axis 37 against the frame 22 ', the offset of the axis 37 again being chosen such that the front railing 25' comes to lie parallel to the frame 22 'with its outside. When the work platform 23 'is folded up, two foldable support struts are folded together at the same time.
