The invention relates to a heavy-load elevator which comprises a hollow cylinder barrel, a lifting device and a lifting device. The lead screw extends in the vertical direction and is located in the cylinder barrel, and the lead screw rotates relative to the cylinder barrel around the axis extending in the vertical direction; the sliding seat is arranged on the screw rod and slides up and down relative to the screw rod; the sliding cylinder extends in the vertical direction and is fixedly connected with the sliding seat; the bearing piece is arranged at the upper end part of the sliding cylinder and is used for jacking and lifting a heavy object; the sliding part is fixedly arranged on the sliding seat; the sliding groove extending in the vertical direction is formed in the inner wall of the cylinder barrel, and the sliding piece is arranged in the sliding groove in a sliding mode; the limiting piece is fixedly arranged on the upper portion of the cylinder barrel, the limiting piece is in sliding contact with the sliding barrel, and the fit clearance between the limiting piece and the sliding barrel is smaller than that between the inner wall of the cylinder barrel and the sliding barrel; the motor is used for driving the lead screw to rotate relative to the cylinder barrel around the axis extending in the vertical direction.
