ABSTRACT:
A traveling device for raising or lowering persons or objects for theater stages or the like has a two-part traveling carriage. The two traveling carriage parts (1 and 2) are connected by lattice girders 3 to form one unit. Elevating platforms 4 of different sizes can be suspended on the cable winches of the traveling carriage parts. The winch frames 9 are telescopic 10. The lowering device is consequently variable in terms of the size of its elevating platform and the lifting height. The modular concept permits easy transportation in the form of individual parts and simple set-up of the lowering device.
