Definitions

  • the invention relates to a spreader with a center of gravity compensation device, preferably for loading containers into or out of ships.
  • Cranes with single or double-hooked surfaces are increasingly used for container handling.
  • swivel or rotating devices are provided between the crane hook and the spreaders attached to them, with the aid of which a load hanging underneath can be moved from the cockpit of the crane to any angular position about the vertical axis.
  • the disadvantage of these cranes is that when an eccentrically loaded container is picked up, the container is skewed due to the off-center position of the center of gravity. Such skewed containers are difficult or impossible to insert into the narrow ship's cells of the container ships or impossible to lift out of the ship's cells due to jamming.
  • spreaders are known, e.g. B. DE-A 2 839 069, in which a suspension tower on a spreader frame is arranged displaceably in its longitudinal direction, the suspension tower being displaced until the suspension point lies exactly above the center of gravity of the container.
  • the invention has for its object to provide a construction in which the disadvantages of the known spreader design are avoided.
  • the present invention is based on a spreader with a spreader frame and a suspension tower which can be displaced on the frame by means of a piston / cylinder construction, the characteristic features being that an intended piston / cylinder version with one end on the displaceable suspension tower and with the the other end is attached to a displaceable cross member, at the ends of which there is a further piston / cylinder version, which are attached at one end to the spreader frame.
  • the invention provides a spreader with which loads with an eccentric center of gravity can be moved effortlessly and which is characterized by a simple and robust construction.
  • each of the two outer piston / cylinder designs are selected to be half as large as the pressure-pressurized surfaces of the internal piston / cylinder design, in order to adjust the displacement speed of the suspension tower both in one and the same size in the other direction.
  • the suspension tower 2 has a plurality of sliders 3 which grip around two T-beams 4 in their upper region and which allow the hanging tower 2 to be moved on the T-beams 4.
  • the T-beams 4 are welded onto a spreader frame 5.
  • the cylinder of a piston-cylinder version 6 is articulated on the suspension tower 2.
  • the piston of the piston / cylinder version 6 is on a cross member 7 which is also displaceable on the T-members 4, at the ends of which a piston of another piston / cylinder design 8 or 9 is articulated.
  • the cylinders of the piston-cylinder versions 8 and 9 are articulated on the spreader frame 5.
  • the piston / cylinder version 6 has two pressure medium connections 10 and 11. Pressure medium connections 12 and 13 are provided in the piston / cylinder version 8 and pressure medium connections 14 and 15 in the piston / cylinder version 9.
  • the operation of the spreader according to the invention is as follows: With the pressure medium supply to the pressure medium connection 10 of the piston / cylinder version 6 and simultaneous blocking of the pressure medium connections 13 and 15 of the piston / cylinder versions 8 and 9, the suspension tower 2 moves to the left. In this situation, the displaceable cross member 7 remains in its position. The suspension tower 2 is returned to the central position by supplying the pressure medium to the pressure medium connection 11 of the piston-cylinder version 6.
  • the pressure medium connections 12 and 14 of the piston / cylinder versions 8 and 9 are supplied with pressure medium.
  • the pressure medium connection 11 of the piston / cylinder version 6 is blocked, so that when the cross member 7 is moved to the right, the suspension tower 2 is also moved to the right.
  • the execution of the suspension tower 2 in the middle position happens in that the pressure medium connections 13 and 15 are supplied with pressure medium. In the middle position of the suspension tower 2, all pressure medium connections 10, 11, 12, 13, 14, 15 are blocked, so that the suspension tower 2 is firmly locked in this position and an unwanted displacement is impossible.

2. Cadre de levage selon la revendication 1, caractérisé en ce que les dispositifs à piston/cylindre (6 ; 8 ; 9) et la traverse (7) sont disposés dans un seul et même plan horizontal.
3. Cadre de levage selon la revendication 1, caractérisé en ce que les surfaces, soumises à l'action du fluide sous pression, de chacun des deux dispositifs extérieurs à piston/cylindre (8 ; 9) sont deux fois moins grandes que les surfaces, soumises à l'action du fluide sous pression, du dispositif intérieur à piston/cylindre (6).
