Active suspension adjustment mechanism for use in a crane with a three point hoisting mechanism wherein three hoist cables run in a multiple fall arrangement to an object suspension device. In respectively a one-fold, twofold and threefold actuated configuration, the mechanism comprises one, two or three interconnected pairs of sheaves for accommodating the hoist cables in opposite directions. The sheave pairs are movable as a unit along a motion axis of the sheave pair parallel to the direction of the hoist cables by associated adjustment actuators for establishing movement of the object suspension device.
