Cable winch hoisting device for stages

A cable winch hoisting device for theatrical stages, comprising:

• a plurality of elongated, rod-like holding girders, said holding girders being adjustable in height between two end positions without mutual hindrance in clearance spaces that do not overlap mutually and are allocated to the holding girders;
• at least two cables, each cable being uniformly adjustable by a cable-operating device, said cables acting on the holding girders and distributed over their length, wherein said holding girders are suspended on said cables and are adjustable in height by altering a free cable length between a cable suspension and the holding girder, determining the position of the respective holding girder;
• a cable drum within each cable-operating device, wherein said cables acting on one of said holding girders are wound up side by side onto said cable drum of the respective cable-operating device with a same change in free cable length which determines the position of the holding girder, said cable drums being designed in a bowl shape and accommodating in their interior almost completely a drive device which is necessary for electric drive and is functional independently of the cable drums;
• wherein several cable-operating devices are each arranged in a stationary mount side by side horizontally in close proximity, and wherein the cable-operating devices are situated side by side in a direction of axes of their cable drums.
