Abstract (en)
[origin: US4644873A] An electric overhead trolley conveyor is described whereby electric trolleys can drive automatically with reduced velocity in inclining, declining or vertical sections or in selected horizontal sections of the rail without a special control of the electric motor or the drive. For this purpose, chains or racks are provided in sections for reduced speed which mesh with sprocket wheels or gears of the electric trolleys. In the other areas of the rail the electric trolleys are driven by a drive wheel. The circumferential velocity of the drive wheel is greater than the circumferential velocity of the sprocket wheel or gear. In the slow movement sections the circumferential velocity difference is compensated by the drive wheel which has an outer ring, that may rotate relative to an inner hub which is fixedly connected with the drive shaft.
