The invention disclose a magnetic force lifting appliance. The magnetic force lifting appliance comprises traction mechanisms, a lifting mechanism and a beam, wherein the traction mechanisms are arranged at the upper part of the beam and the lifting mechanism is arranged at the lower part of the beam. The lifting appliance is characterized in that the lifting mechanism at least comprises three U-shaped sliding blocks and a underframe, the three U-shaped sliding blocks are orderly sleeved, the inside U-shaped sliding block is arranged in a notch of the adjacent outside U-shaped sliding block in a sleeving manner, the distance between the top ends of the two adjacent U-shaped sliding blocks is H, and the top end of the inside U-shaped sliding block is lower than the top end of the outside U-shaped sliding block, the top end of each U-shaped sliding block is provided with a spring, the outermost U-shaped sliding block is arranged on the underframe, and a suspension arm is arranged in the innermost U-shaped sliding block; two sets of traction mechanisms are symmetrically arranged at two sides of the upper part of the suspension arm; each traction mechanism further comprises a traction chain, a magnet and a rotating shaft; the traction chain sleeves the rotating shaft, the magnet is fixed on the traction chain, the outer end of the magnet is provided with roller wheels, the outer end of the magnet is S pole, and the top end of the U-shaped sliding block is N pole. The attraction distance of the magnet is promoted through the combination of U-shaped sliding blocks and the movement of the traction mechanisms, thereby realizing the effect of hoisting articles.
