ABSTRACT:
A cable drive for a hoisting mechanism, including a carrying element having a recess, at least one of a top block and a cable end attachment, each of which has a horizontal swivel axle having two ends, and bearing elements swivelably mounted at both ends of the axle so that each of the bearing elements is rotatable by 180 degrees relative to its vertical central plane. The bearing elements are arranged in the recess of the carrying element, each bearing element having a laterally offset bearing bore in which the swivel axle is mounted so that movement of the bearing element causes a lateral parallel movement of the swivel axle.
