The pairs of levers are connected to one another by downwardly curved crossbars. A drive mechanism is mounted preferably beneath the lifting platform and comprises a helical shaft (screw) connected by a chain drive to a motor and a reduction drive. Mounted on each end of the helical shaft are nuts that are connected to the levers by pairs of angled arms. The helical shaft is connected to the motor by an electromagnetic clutch.
