Definitions

  • the invention relates to a vehicle telescopic crane with a jib which is detachably arranged at the outer end of the last telescopic part.
  • Such cranes are equipped, inter alia, with a luffing jib, which, as a pure jib extension, is fastened in alignment with this at the end of the outer telescopic part.
  • This increases the outreach or height of the crane by the length of the luffing jib compared to the version, which is not provided with it, without the need for a further telescopic part with its considerable manufacturing effort and weight.
  • An increase in the permissible load capacity of the crane is not associated with this, however, since the telescopic boom of the crane is loaded with the weight of the jib. This weight is considerable because the luffing jib is designed as a bending beam.
  • an adapter for attachment to the end of the telescopic part an optionally fixed on the adapter or pivotable against the tilting direction of the telescopic boom, and an optionally fixed on the adapter and the trestle or on the adapter in the tilting direction of the telescopic boom has pivotably articulated luffing jib.
  • the trestle can be braced with respect to the telescopic boom and the luffing jib with respect to the trestle, and thus both or at least the trestle or luffing jib can only be designed as a pressure support, that is to say much more easily.
  • the previous use for the luffing jib as a pure jib extension remains within the limits that are drawn by the lighter design when used as a bending beam. At higher loads, the guying is used with the trestle tilted.
  • the trestle is held in the pivoted-out position, acting as a pressure support, by means of an anchoring guided from its tip to the outer end of the penultimate telescopic part.
  • This bracing can already be made and adjusted according to the expected operating conditions when the jib is installed on the ground.
  • the distance between the anchor point of the guying on the penultimate telescopic part and the tip of the crane remains fixed if the extension of the last telescopic part from the penultimate does not change, for example as a result of a lock.
  • the tilt position of the trestle can also be changed by changing the extension.
  • the basic telescopic part is laterally provided with holders for receiving the luffing jib pivoted against the basic telescopic part or detached from the end of the telescopic part in its folded position.
  • the foldability of the two parts of the luffing jib allows the luffing jib to be dimensioned to practically twice the length of the basic telescopic part. If the luffing jib remains articulated on the outer telescopic part when moving to the transport position, the retrofitting can be carried out with the least possible equipment and time. If the luffing jib is detached, it can be placed on the basic telescopic part in the best possible assignment.
  • the telescopic boom has a basic telescopic part 1, a second telescopic part 2, a penultimate telescopic part 3 and an outer telescopic part 4.
  • an adapter 7 is detachably fastened via pivot bearings 5 and fixed points 6.
  • a trestle 10 is arranged via tilting bearing 8 and optionally additionally via locking points 9, the tip of which supports the lower block 11 of a block and tackle 12.
  • the tip of the tilted trestle 10 is anchored via a tension cable 13 to the end 14 of the penultimate telescopic part 3.
  • the upper bottle 15 of the block and tackle 12 is attached to the end of a flat iron 16, the other end of which is articulated at the tip 17 of the luffing jib consisting of two parts 18a and 18b is.
  • the traction cable 19 of the block and tackle 12 is guided to the superstructure of the vehicle telescopic crane.
  • the two parts 18a and 18b of the luffing jib can be folded against one another about the folding point 20.
  • the luffing tip 18a, 18b is in turn pivotally articulated in the locking points 9 on the adapter 7.
  • the luffing jib For the transport of the vehicle telescopic crane, the luffing jib is erected, its attachment point 21 is connected to the tip of the trestle 10, the telescopic jib 1, 2, 3, 4 is telescoped and lowered, the luffing jib is folded up and the jib is pivoted against the basic telescopic part 1 via the swivel bearing 5, so that it bears against it.
