Abstract

A mobile telescopic crane has three extending sections (2, 3, 4) which are braced by external cables (7) which pass over the tips (5) of external side-struts (6). The side-struts swivel as required between a first transport position parallel to the crane base (2) and a second operational position, powered by jacks. The cable (7) top zones esp. have fixed sleeves. The side-struts have cable locking traps which engage with the sleeves in the retracted mode.

1. Telescopic boom of a crane with a pivoting section ( 2 ), telescopic sections ( 3 , 4 ) telescopic sections ( 3 , 4 ) and a guy ( 5 ), the two on one of the sections ( 2 , 3 , 4 ) articulated from the articulated section ( 2 ) span support (6), of these supported guy cables (7) and a pressure medium device (15) for pivoting the guy supports (6) has, wherein the guy supports (6) parallel from one another substantially at one of the sections (2, 3, 4 ) folded transport position can be pivoted into an erected operating position, characterized in that the guy ropes ( 7 ) have thickening pieces ( 25 ) towards their ends and rope locks ( 22 ) are provided on the guy supports ( 6 ) which are connected to the thickening pieces ( 25 ) can be brought into positive engagement.
2. Telescopic boom according to the preceding claim, wherein the compression pieces consist of pressed-on cable clamps ( 25 ).
3. Telescopic boom according to one of the preceding claims, wherein each of the guy ropes ( 7 ) has a plurality of spaced-apart thickening pieces ( 25 ) and a cable lock, which can pass through the respective guy rope with one or more of the thickening pieces ( 23 ) or one of the thickening pieces ( 23 ) captures, is provided.
4. Telescopic boom according to the preceding claim, wherein the cable lock ( 22 ) has a movably mounted locking piece ( 23 ) which is movable in and out of the way of the guy rope ( 7 ), preferably the locking piece ( 23 ) pivotally mounted and a power lift ( 24 ) for actuating the locking piece ( 23 ) is provided.
5. Telescopic boom according to one of the preceding claims, wherein on the guy supports ( 6 ), preferably inside the guy supports ( 6 ) rope storage ( 16 ) for the guy ropes ( 7 ), in particular storage bottles ( 16 ), into which the guy ropes ( 7 ) can be confiscated, are provided.
6. Telescopic boom according to one of the preceding claims, wherein at the ends of the guy ropes ( 7 ) auxiliary ropes ( 20 ) for catching the guy ropes ( 7 ) are fastened, preferably inside the guy supports ( 6 ) auxiliary winches ( 21 ) for winding the auxiliary ropes ( 20 ) are provided.
7. Telescopic boom in particular according to one of the preceding claims, wherein each of the guy supports ( 6 ) about two pivot axes ( 11 , 12 ) is pivotable such that the guy supports ( 6 ) from the substantially parallel to each other on one of the shots ( 2 , 3rd , 4 ) folded trans port position in an erected operating position in which the guy supports ( 6 ) are spread out in a V-shape, are pivotable, and each of the guy supports is assigned only a single pivot cylinder ( 15 ), with the help of which the respective guy support ( 6 ) about its two pivot axes ( 11 , 12 ) is pivotable.
8. Telescopic boom according to the preceding claim, wherein the guy supports ( 6 ) are pivotable separately about each of the pivot axes ( 11 , 12 ).
9. Telescopic boom according to one of the preceding claims, wherein each of the two pressure medium cylinders ( 15 ) with its guy support end and its boom end can be pivoted in multiple axes, in particular special gimbal.
10. Telescopic boom according to one of the preceding claims, wherein at least one of the pivot axes ( 11 , 12 ) of each guy support ( 6 ), before preferably each of the pivot axes ( 11 , 12 ) has a pivot axis lock, with the aid of which the pivotability of the guy support ( 6 ) is lockable about the respective pivot axis ( 11 , 12 ).
11. Telescopic boom according to one of the preceding claims 1 to 6, wherein each guy support ( 6 ) is assigned a plurality of pressure medium cylinders for pivoting the respective guy support about a plurality of pivot axes ( 11 , 12 ).
12. Telescopic boom according to one of the preceding claims, wherein the tensioning supports are hinged to bearing brackets ( 10 ) which are rigidly attached to one of the shots ( 2 , 3 , 4 ) on opposite sides thereof, preferably on the collar ( 9 ) of the Articulation shot ( 2 ) are arranged.
