Definitions

  • the invention relates to a crane vehicle with a boom articulated on its uppercarriage, preferably a telescopic boom, which can be rocked by a rocking cylinder articulated on this and the uppercarriage, with extendable sliding spars arranged on the opposite end regions of the longitudinal sides of the undercarriage, which extend at their ends with extendable ones Support feet are provided, and with an overload protection device that generates a signal and / or stops the crane operation when the crane approaches or exceeds its stability-threatening limits.
  • the stability of a crane vehicle with a telescopic boom depends not only on the size of the load hanging on the telescopic boom, but also on the luffing angle and extension length of the telescopic boom, on the deflection of the telescopic boom and in particular also on the angle of rotation of the uppercarriage with the telescopic boom to the undercarriage and through the support feet of the sliding beams defined stand square. Relative to the quadrilateral defined by the extended sliding beams and support legs, the stability of the crane is greatest when the boom points in the direction of the most extended sliding beam. When the sliding spars are retracted with the support legs extended, the stability in the longitudinal direction of the undercarriage is greater than in the direction of its transverse axis. The overload protection must therefore always take into account the extension status of the sliding spars, which can be problematic in that the stability changes even with different extension lengths of individual sliding spars.
  • the object of the invention is therefore to create a crane vehicle of the type specified at the outset, in which the overload protection device takes into account the different extension lengths of the sliding beams in a simple and reliable manner.
  • this object is achieved in a crane vehicle of the type specified at the outset in that a monitoring device is provided which detects the extension state of the sliding spars, which supplies the overload protection device with signals corresponding to the respective extending state of the individual sliding spars, and in that the overload protection device when determining the limits endangering stability for all sliding beams, the minimum extension length of one of the sliding beams is assumed.
  • the invention is based on the knowledge that when the limits jeopardizing the stability of the crane are detected, it will always and reliably remain on the safe side if, irrespective of the different extension lengths of the sliding spars, only the smallest extending length of a sliding spar is assumed, which then, independently of the larger extension lengths, the other sliding spars are also taken as a basis, so that only a smaller standing square is taken into account than may be the case due to the longer extending lengths of individual sliding spars.
  • a device monitoring the bolting of the sliding beams can be provided, which emits a signal to a central monitoring unit when a sliding beam is not bolted.
  • an undercarriage 1 of a crane vehicle can be seen schematically, from which sliding beams 2 can be extended, which support legs 3 at their ends, which can be extended vertically against the ground by hydraulic cylinders at right angles to the sliding beams.
  • the sliding beams 2 are located in the end regions of the two long sides of the undercarriage 1 and can be extended at right angles to its longitudinal center plane.
  • the sliding beams can be extended in three stages, in which they must each be bolted in their guides.
  • the sliding beams 2 are in their middle extended state.
  • the sliding beams located on the left-hand side of the vehicle are extended to their middle position, while the sliding beams located on the right-hand side are fully extended.
  • the stability it is therefore assumed that there is only one state in which all the sliding spars are only extended to their middle position, as can be seen from the right sketch in FIG. 2a.
  • the left-hand column in turn extends the sliding spars to different extents, one sliding spar in each case being in its shortest extended position or retracted position. Therefore, as can be seen from the right-hand side of FIG. 2, only one state is assumed for the determination of the standing square to be taken into account in the safety analysis, in which all the sliding beams are in their retracted position.
