Definitions

  • the gripping element is vertically divided into two parts which are joined together by two linkage arms so that in the quadrangle delined by the pivot points of the linkage arms at least two opposite sides are non-parallel, and that the parts are furthermore interconnected lby a pressure cylinder for moving the lower part in relation to the upper part.
  • a ship in harbor often has a list.
  • An object of the present invention is to provide an extraordinarily simple solution to the above-mentioned problem.
  • the invention is characterized in that the gripping element is vertically divided into two parts which are joined together with two linkage arms so that in the quadrangle defined by the pivot points of the linkage arms at least two sides are non-parallel, and the parts are furthermore interconnected by means of a pressure cylinder for the purpose of moving the parts relative to each other. It is immaterial which pair of opposite sides of the said quadrangle are non-parallel.
  • the lower part of the gripping element is tilted when it is displaced with reference to the upper part.
  • FIG. 1 shows the gripping element in elevational view
  • FIG. 2 shows the same gripping element with its lower part tilted with reference to the upper part.
  • the gripping element shown in the drawing is intended to be suspended from ropes attached to rings 1 in a harborsde crane.
  • the gripping element is used to hoist containers.
  • FIGS. 1 and 2 the ends of the long body 3,544,149 Patented Dec. 1, 1970 ice engaging the container, or of the lower part 2 of the gripping element, have not been shown.
  • the gripping element is vertically divided into two parts 2 and 3, which are joined together with linkage arms 4 and ⁇ 5.
  • the lower part 2 and upper part 3 are furthermore interconnected by a pressure cylinder 6.
  • the cylinder 6 is mounted on the upper part 3 and its piston rod 7 is attached to the lower part 2.
  • the quadrangle defined by the pivot points of the linkage arms 4 and 5 is a trapezoid in which the linkage arms 4 and 5 are non-parallel.
  • The'- lower ends of the linkage arms 4 and 5 are connected to a carriage 8, which is provided with rollers 9.
  • the rollers 9 support the lower part 2 of the gripping element by means of the rail 10 which rests on rollers 9.
  • the lower part 2 of the gripping element may thus be longitudinally displaced in relation to the carriage 8.
  • a gripping element adapted for being suspended from the hoisting ropes of a crane and positioned at various inclinations, said gripping element comprising a first element adapted for support by the ropes of the crane, a pair of linkage arms pivotably connected to said iirst element and depending therefrom, a carriage pivotably connected to said linkage arms such that the pivotal connections between said linkage arms and the rst element and carriage deiine a quadrangle with two opposite non-parallel sides, a second gripping element supported by said carriage and adapted for gripping a load, and a pressure cylinder connected to said rst and second elements for moving the second element in relation to the first element.
  • a gripping element as claimed in claim 1 comprising means supporting said second element for displacement on said carriage.
  • a gripping element as claimed in claim 2 wherein said means comprises wheels on said carriage rollably supporting said second element thereon.
