Arrangement for placing crane mechanisms

An arrangement for placing crane mechanisms, the crane comprising

• lifting mechanisms (1) with lifting drums (2),
• lifting ropes (3) arranged to the lifting drums (2),
• a lifting trolley (4),
• a loading element (5) suspended from the lifting trolley (4) by the lifting ropes (3) and having turning sheaves (8) for the lifting ropes for guiding the lifting ropes back to the lifting trolley,
• four auxiliary mechanisms (10) independent of the lifting mechanism (1) and each other for controlling the swaying and twisting of the loading element (4) 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 (9), through which the auxiliary ropes that are led to them diagonally from the rope drums (11) of the auxiliary mechanisms are directed back to the lifting trolley (4), wherein
• 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) of the auxiliary ropes to a storage drum (14) for auxiliary ropes in the lifting trolley (4),
• characterized in that
• the lifting mechanisms (1) with their lifting drums (2) are fixed to the structural frame of the crane, and
• the storage drum (14) is equipped with an additional mechanism (15) that is independent of the lifting mechanisms (1), but can be controlled in a synchronized manner with them.
