For a method and device for raising and lower and for swiveling an object (21) having at least one preferred direction of extent, for example a rod, a plate, in particular an acoustic panel, the device comprising at least one support element (22) for raising and lowering the object (21) and at least one further support element (26) for swiveling the object, the at least one support element (22) for raising and lowering the object and the at least one support element (26) for swiveling the object (21) are or can be coupled to a common drive (24), wherein the support elements (22, 26) can be wound on a common rope drum (23) and can be unwound from said common rope drum, the rope drum (23) is coupled to the common drive (24), and at least one sub-section (23', 23'') of the rope drum for acting on the support element for swiveling can be decoupled from a sub-section that interacts with the support element for raising and lowering so that a reduced number of drives (24) and a simplified controller can be sufficient for raising and lowering and for swiveling an object (21).

Abrégé

The invention relates to a method and system for balancing forces or torques in a point-hoist system or flybar system or coupled point-hoist and flybar system having a plurality of actuators (30) for moving an object (6) hanging on ropes, wherein the following elements are provided: a sensor (18) associated with each actuator (30) for determining the force or the torque of each actuator (30) during the motion of the object (6) to be transported, a fixing device for fixing at least two actuators, the respective determined values of the force or the torque of which are defined as reference variables, an additional open- or closed-loop control device (16) for controlling the force or the torque of at least one actuator different from the actuators used to define the reference variables in approximation of one of the reference variables in an open- or closed-loop manner. Thus it is possible, in particular, to avoid overloading individual actuators or motors (30) during the motion of an object (6) hanging on ropes.
