Abstract
An electrically powered jack for raising a motor vehicle has a triangular base which supports a motor driving a vertical screwed shaft through bevel gears. The screwed shaft is supported on a ball bearing and engages a nut fixed to the lower end of a tube. The tube carries a pad at its upper end to take the weight of the vehicle. The driving motor is switched off by limit switches mounted on a rod and placed at the highest and lowest positions of an outer tube which surrounds the inner tube.
