  • Patent number: 6729605
    Abstract: A cable winch hoisting device for theatrical stages, whereby a plurality of elongated, rod-like holding girders are suspended on cables, and these holding girders are adjustable in height by varying the free cable length between the cable suspension and the holding girder, which determines the position of the respective holding girder. The holding girders are adjustable in height between two end positions without any mutual interference in the clearance spaces which do not overlap with one another and are provided for the holding girders. At least two cables which are uniformly adjustable by the same cable-operating device act on the holding girders and are distributed over the length of the girders. The cable-operating devices are each electrically driven cable drums. The cables acting on the same holding girder can be wound up side by side onto the cable drum of the respective cable-operating device with the same change in free cable length, which determines the position of the holding girder.
