Definitions

  • the invention relates to a loader crane which can be attached to a truck and which has a boom which can be pivoted about a horizontal axis relative to the stand of the crane, with a tilt arm which can also be pivoted about a horizontal axis at its outer end, and an extension arm which extends coaxially to the tilt arm, wherein form on both sides of the boom and rocker arm pivoted levers with these quadrilaterals on which a hydraulic unit for pivoting the rocker arm engages, which continues the boom in a horizontal position in plan view including an angle, so that the pivoted rocker arm in the folded-down position of the boom laterally next to the stand runs.
  • DE-AS 2 012 145 proposes a loading crane in which the side walls of the boom and of the tipping arm run parallel to one another over their entire length.
  • this is paid for by the measure of arranging the articulated axis connecting the boom and the tilt arm at an angle to these two parts which continue in a straight line in plan view.
  • the normal vertical movement of a load is only possible if the angle between the boom and the tipping arm remains unchanged, that is to say the pivoting only via the boom is done.
  • the facility described last has therefore not been used in practice.
  • the invention is now based on the objective of enabling a simple construction of the boom used and of the tilt arm used, the rocker arm at the same time being supposed to be articulated on the end face of the boom.
  • the length of the rocker arm should not be limited by the distance of its pivot axis to the stand of the loading crane and the coaxial arrangement of the extension arm in the rocker arm should be possible.
  • the invention achieves this goal in a device of the type outlined at the outset in that the pivoting levers leading from the boom on both sides to the hydraulic unit on the rocker arm are offset in relation to the pivoted levers leading from the rocker arm to the hydraulic unit in the direction of the deflection of the rocker arm in the horizontal position relative to the boom, so that the side walls of the boom also run parallel to one another in the end region of the boom adjoining the articulation point of the swivel arms.
  • the asymmetrical arrangement of the swivel levers allows the entire boom to be designed as a simple, sloping box section.
  • the required lateral displacement of the pivot axis of the rocker arm can be achieved with the inclination of the boom remaining the same everywhere, which is also less than before, which leads to a constant distribution of the torsional forces.
