Abstract: A method and assembly for operating at least two lifting gears in a group operation, where each lifting gear has a hoist via which a respective cable or chain can be raised or lowered. The hoists are first operated in a synchronous operating mode to perform a common lifting procedure to move a load supported by the hoists. At least one of the hoists involved in the common lifting procedure is then deactivated to switch from the synchronous operation into an individual operation or a multi-operation, with at least one of the hoists remaining activated to carry out a lifting or lowering process relative to each deactivated hoist. A load value is then determined for the at least one deactivated hoist and compared to a predetermined threshold value of the at least one deactivated hoist.

A pendulum swing angle of the load corresponding with the ideal sequence of lifting carriage accelerations is calculated. The swing angle calculation and a geometric model of the swing damping system are used to determine a swing damping system control signal which makes the swing damping system follow the swing angle of the load.
