The invention discloses an anti-reverse-rotating material lifting device which includes five parts of a supporting assembly, a driving assembly, a lifting assembly, a shock absorbing assembly and a ratchet assembly, wherein the supporting assembly includes a base, a motor fixing seat fixed on the base and a pulley mounting plate fixed to one side of the base; the driving assembly includes a motorinstalled on the motor fixing seat; the ratchet assembly includes a ratchet, a brake lever and a pawl; the lifting assembly includes a first pulley arranged on the pulley mounting plate, a second pulley mounted coaxially with the ratchet, and a belt wound on the first pulley and the second pulley; and the shock absorbing assembly includes a shock absorbing support, three hydraulic shock absorbersfixed to the shock absorbing support, and pressure plates arranged on the hydraulic shock absorbers. By arranging the ratchet assembly, matched with a pair of pulley blocks and supplemented by the shock absorbing assembly, the anti-reverse-rotating material lifting device has the effects of anti-reverse rotation, shock absorption and large torque.
