Definitions

  • the invention relates to a load lifting system with at least one cable drum mounted on a lifting frame for a plurality of lifting cables, each of which is guided to a fixed point around pulleys of a traverse and the lifting frame.
  • a load lifting system of this type according to DE-PS 29 17 588, two cable drums for each lifting cable are available for lifting and lowering the cross member connected to the load. These pulleys are arranged coaxially with each other and can be connected to each other to maintain synchronism.
  • a stabilizing cable drum is available to prevent pendulum movements of the traverse and is connected to the lifting cable drum by means of a drive. From the stabilizing cable drum, stabilizing cables lead diagonally via pulleys of the lifting frame to pulleys of the traverse, where they are guided to fixed points via tensioning and damping devices. These tensioning and damping devices are complex and can yield, so that pendulum movements of the traverse with the load are not prevented in an intended manner.
  • the object of the invention is therefore to make a load lifting system of the type described cheaper and safer.
  • This object is solved by the features of the main claim.
  • the hoisting ropes are initially guided vertically from the rope drum to the rope pulleys on the inner longitudinal members of the traverse and thus take over the lifting function.
  • the cables are guided vertically or approximately vertically between the cable drum and the crossbar, both when the crossbar is raised and when it is lowered, so that there are no large cable deflections on the cable drum and the pulleys.
  • the lifting ropes are then after deflection to vertical to the rope pulleys arranged horizontally on the crossbar Rope pulleys guided, which are arranged approximately in the middle of the longitudinal and cross members.
  • the eight hoisting ropes are guided in opposite rope grooves in only one rope drum, the rope outlet side of which is arranged in the longitudinal center axis of the crossmember.
  • the lifting ropes can be attached to the fixed points of the crossbar via length adjustment devices. Since all hoisting ropes are always loaded equally, no different rope lengthening is to be expected and subsequent adjustment is not necessary.
  • Fig. 1 it can be seen that pendulum movements transverse to the cable drum 1 by the hoisting ropes 30, 60; 40 and 50 can be prevented.
  • Pendulum movements in the longitudinal direction of the rope drum are prevented by the inclined ropes 10, 20, 70 and 80 which can be seen in FIG and 85 back down to the lower fixed points 16, 26, 76 and 86 on the side member 6T.
  • Fig. 2 opposite arrows are entered in the cable drum 1, which indicate the opposite directions of the cable groove.
  • the rope 10 runs from the height-dependent run-off point 11 from the rope drum 1 and leads around the rope pulley 12 on the inner longitudinal member 7T of the crossmember 5 around the rope pulley 13, which can be seen in FIG. 3 as a horizontal disc. From there, the cable 10 continues around the middle cable pulley 14 shown in FIG. 2, from there around the upper cable pulley 15 and back again to the fixed point 16 on the longitudinal beam 6T of the traverse 5. In an analogous manner, all other lifting cables are also guided and formed the pulley required anyway.
  • the entry angle on the rope drum and on the rope pulleys 12 to 82 on the inner lower longitudinal member 7T of the crossmember 5 changes only slightly, caused by rope migration on the rope drum 1, as can be seen in FIG. 2.
  • This rope migration is small, however, so that the traverse 5 can be lowered far without excessive rope deflections occurring inadmissible.
  • This invention thus allows pendulum-free load transport by means of a rope guide even with larger lifting heights.
