PCT No. PCT/EP88/00390 Sec. 371 Date Nov. 28, 1989 Sec. 102(e) Date Nov. 28, 1989 PCT Filed May 6, 1988 PCT Pub. No. WO88/09764 PCT Pub. Date Dec. 15, 1988.In a lifting device for a platform for storage of motor vehicles wherein the platform is carried by carrying chains which are raised and lowered via driven chain wheels and are guided via deflection pulleys on the platform, in order to simplify the design and to enable lifting in the manner of a pulley block with only two carrying chains, it is suggested that there be arranged on each side of the platform a carrying chain, the one end of which is stationarily held in the region above a corner of a platform, from which it hangs downwards and passes over a first deflection pulley mounted for free rotation on a side of the platform, from which it runs over a second deflection pulley spaced from the first, thereby forming a loop in which the platform with the two deflection pulleys is suspended, is led upwards again where it passes over a stationarily mounted drive wheel, and with a gear which is connected to the second deflection pulley for common rotation with the latter and which meshes with a stationary toothed rack substantially parallel to the lifting path or with a stationarily held guiding chain, the respective one of which rests against the gear on the side thereof which faces away from the carrying chain.
