Definitions

  • the present invention relates to a crane, in particular a suspended slewing crane, having the features of the preamble of claim 1.
  • the implement can be moved in a generic crane by a vertical pivoting device from a vertical. But such cranes have a disadvantageously large design.
  • the object of the invention is to provide a generic crane, which has a more compact design.
  • the at least one hydraulic line coming from the crane arm can pass between the pivot bearings, space is created for the articulation of the vertical pivoting device, which allows a compact design.
  • FIG. 1 and FIG. 2 (equals to FIG. 1 with partially broken away swivel head 9) show a crane designed as a suspended crane according to the invention.
  • a crane arm 1 On a crane arm 1 (which is usually telescopically mounted in a further crane arm, not shown) is a Kranarmkopf 8 fixed.
  • a device body 7 of a trained here as a gripping device see also FIG.
  • the bracket 17 may be formed integrally with the swivel head 9 or attached thereto.
  • Hydraulic lines 3 run from the crane arm 1 coming (where they can be mounted by means of brackets on Kranarmende) to a rotary distributor 6 to allow a transport of hydraulic fluid to the implement 2 without being affected by the rotational movement. This allows an endless rotation of the implement 2. Because the hinge has two spaced pivot bearing 10, with a split pivot pin 11 a, 11 b, the hydraulic lines 3 can run protected in the pivoting head 9. At the swivel head 9, a cover, not shown, - preferably releasably - be attached, which improves the protection of the hydraulic lines 3. Further hydraulic lines 3 run from the crane arm 1 coming (where they can be mounted by means of brackets on Kranarmende) to the rotary motor 4 to supply them.
  • a pivot pin connecting the spaced-apart rotary bearing 10 could also be used, provided that its diameter is small enough that the hydraulic lines 3 can run between the pivot bearings 10.
  • the rotary distributor 6 is installed head-down relative to a standard installation position and protrudes into the device body 7 substantially as far as a gripper cylinder 14 (see FIG FIG. 3 ).
  • the grippers 13 are movable in a conventional manner.
  • the gripper cylinder 14 is supplied via the rotary distributor 6 away leading hydraulic lines 3 'and the rotary distributor 6 leading hydraulic lines 3 regardless of a rotational and vertical pivot position of the implement 2 with hydraulic fluid.
