Problems solved by technology

[0008] However, in the lifting devices of this type known on the market, the mechanical alternating stress of the belt is still relatively large when it is wound on or unwound from the lifting drum

Embodiment Construction

[0024] exist figure 1 The lifting device shown in a schematic perspective view and generally designated 1 comprises a lifting drum 2 , which is itself rotatably mounted on a mounting platform 5 via bearings 3 , 4 . The lifting drum 2 can be rotated in both directions by means of an electric motor 6 which is likewise fastened to the mounting platform 5 . The installation platform 5 is arranged at a certain height above the floor of the room, for example by means of a steel structure not shown for the sake of clarity.

[0025] A load, shown schematically as plate 7 , is suspended on lifting drum 2 via a steel belt 8 . To this end, the steel belt 8 has at its lower end a safety hook 9 which can be inserted into a lifting lug 10 of the load 7 . The upper end of steel band 8 is fixed on the lifting reel 2. When the lifting drum 2 rotates, the steel strip 8 is wound on the lifting drum 2 more or less in mutually superimposed turns, or is unwound from this drum depending on the di...

Abstract

A lifting device (1) for lifting and lowering a load (7) in a known manner comprises a lifting drum (2) drivable in both directions and at least one strap (8) used as a traction device ), said strap is fixed at one end to the lifting drum (2) and has a holding device (9) for the load on the other end. The tape (8) can be wound on the drum (2) by rotating the lifting drum (2) in such a way that one loop is superimposed on the other. In order to reduce the mechanical alternating stress at the step formed by the end (15) of the strap (8) fixed on the circumferential wall of the lifting drum (2), on the circumferential wall of the lifting drum (2) At least one spacing element (17) is provided against which the first turn of the strap (8) rests.

Description

technical field [0001] The invention relates to a lifting device for lifting and lowering a load, which has [0002] a) a lifting drum; [0003] b) a driving device, by means of which the lifting drum can be rotated in two directions; [0004] c) at least one strap used as a traction device, said strap being fixed at one end to the lifting drum and having a holding device for the load at the other end; [0005] in, [0006] d) The belt can be wound on the drum by rotation of the lifting drum in such a way that one turn is superimposed on the other. Background technique [0007] Lifting devices are known in various configurations which work with a lifting drum and at least one flexible traction device wound on the lifting drum. In particular ropes, chains and belts are used as traction means. The belt has the advantage that it can be wound on the lifting drum in a particularly well-defined manner and has a relatively high load-bearing capacity, while still remaining suff...
