  • Patent number: 7744334
    Abstract: The present invention relates to a semi-trailer, comprising a gooseneck chassis and a container lifting device with at least one crane part displaceable along the chassis. The chassis comprises frame portions which are vertically displaced relative to each other, where the available vertical space for driving the displaceable crane part is limited particularly in the transition between said frame portions. The displacement of the crane part on one frame portion of the chassis takes place by means of a linearly operating, longitudinally variable elongate actuator, which both in the retracted and in the extended state is positioned substantially within the height limits of the chassis and has a substantially constant angle to the chassis. A vertically articulated link arm is at one end connected to a driving part of the actuator and at the other end articulated to said displaceable crane part.

  • Publication number: 20070140818
    Abstract: The present invention relates to a semi-trailer (1) for transporting containers which is connected to a tractor unit, comprising a gooseneck chassis (4) and a container lifting device with at least one crane part (3) displaceable along the chassis (2). The chassis comprises frame portions (4, 5) which are vertically displaced relative to each other, where the available vertical space for driving the displaceable crane part (3) is limited particularly in the transition (6) between said frame portions. The displacement of the crane part (3) on one frame portion of the chassis (2) takes place by means of a linearly operating, longitudinally variable elongate actuator (7), which both in the retracted and in the extended state is positioned substantially within the height limits of the chassis and has a substantially constant angle to the chassis (2).

  • Patent number: 4019642
    Abstract: Loading device arranged on a vehicle in order to carry out a side-wise transfer of a load onto or away from said vehicle, said device comprising two lifting means spaced from each other and movable substantially in parallel planes, each lifting means having a supporting leg which can be pivoted outside of the outer contour of the vehicle, said supporting leg being pivotably carried in a pivot bearing close to the outer contour of the vehicle, a piston-cylinder unit for pivoting said supporting leg having one end pivotably connected to the free end portion of said leg, the other end of said unit being pivotably carried in a bearing positioned further inside the contour of the vehicle and at a higher level than the pivot bearing of said supporting leg, and said supporting leg having a supporting surface extending substantially along the main portion of said leg whereby to make it possible to adjust the position of the device with respect to supporting foundations on different levels.
