The invention discloses accelerated lifting equipment. A first guide rail and a second guide rail are arranged at two opposite ends of a rack; a first lifting device and a second lifting device are arranged on the rack; the first lifting device is close to the first guide rail; the second lifting device is close to the second guide rail; each lifting device comprises a rewinding roller, a fixed pulley, guide wheels, a guide wheel bracket and a driving mechanism; the guide wheel bracket is arranged on the guide rail; and each driving mechanism can drive the guide wheel bracket to move along the guide rails. The accelerated lifting equipment provided by the invention is reasonable in structural design, two groups of lifting devices are arranged, and the guide wheels of each lifting device are arranged on the guide rail. When materials are lifted, the lifting speed can be adjusted according to the weight of the materials, and the working efficiency is improved; and moreover, the rope inlet angle of a movable pulley is kept invariable in the lifting process, the tension stressed by a pulling rope is maximized in the vertical direction, and the mechanical efficiency is improved.
