A driving-type lifter of a load cell control-type non-gravitational electric motor with a self-movable function is provided to preclude the working load from falling and a worker from being hurt by controlling the brake unit through the off of the relay unit. A driving-type lifter of a load cell control-type non-gravitational electric motor with a self-movable function comprises a hand robot(400) containing a ball screw, a ball screw nut of the sliding part, a speed reducer(204) connected through a coupling, an electric motor(205), a knob(207) combined with a working sensing load cell(206), a controller, and a drive unit driving the electric motor and keeping the balance of the working load; and a self-movable cart(500) having a handle connection part(502), a cart driving body(503) placed with the driving part, a cart body(504) mounted with the hand robot, plural moving wheels(505), a horizontal body and the cart driving body, and a hand robot fixing unit(507) fixing the base of the hand robot. |
