ABSTRACT:
The invention relates to an arrangement for placing crane mechanisms, the crane comprising lifting mechanisms (1) with lifting drums (2), lifting ropes (3) in the lifting drums, a lifting trolley (4), a loading element (5) suspended from the lifting trolley (4) by the lifting ropes (3), four auxiliary mechanisms (10) controlling the swaying and twisting of the loading element (5) and the load (9) fastened to it, auxiliary ropes (12) in the rope drums (11) of the auxiliary mechanisms (10), and turning sheaves (13) of the auxiliary ropes (12) in the loading element (5). The lifting mechanisms (1) and lifting drums (2) are fixed to the frame of the crane, the auxiliary mechanisms (10) with their rope drums (11) are located in the lifting trolley (4), and the auxiliary ropes (12) are led from the turning sheaves (13) to a storage drum (14) for the auxiliary ropes in the lifting trolley (4), the storage drum being equipped with an additional mechanism (15) that is independent of the lifting mechanisms (1).
