Abstract
The description refers to a damping and positioning device for the active damping of the swinging motion of loads suspended from cranes, said device comprising guide ropes running between the crane and the load to dampen the swinging motion of the load. The proposal according to the invention is to provide at least two guide ropes (6a, 6h) for each swinging motion plane, and to arrange guide rope drums (5) on the crane attached to a frame (3, 14) suspended from the latter. The guide ropes (6a, 6h) are loaded by a tensile force which acts constantly against the swinging motion of the load. The tensile force is produced by a drive unit whose driving force is controlled independently of the speed of the guide rope drum. The length of the guide ropes (6a, 6h) is independent of each other and is variable while the crane is in operation.
