FIELD: lifting devices.
SUBSTANCE: invention relates to lifting devices for moving goods and people, has a simplified design, reliable in operation. The device comprises a loading platform and a lifting platform connected to each other by two pairs of scissor-type levers. Pairs of levers are interconnected by crossbars having a downwardly curved shape. The drive mechanism is preferably installed under the lifting platform and contains a screw shaft with multidirectional threads connected by a chain drive to the engine and gearbox. On both sides, nuts are installed on the screw, connected to the levers through pairs of jibs. The screw is connected to the engine through an electromagnetic clutch. The platform is made hollow and contains stops located at the corners, and its bottom has a recess for the electric motor.
EFFECT: simplification of the design of the screw lifting device, mainly its drive mechanism.
