The invention provides an AC (Alternating Current) variable frequency speed regulating loading lift assembly. The AC variable frequency speed regulating loading lift assembly comprises a well and a lift car arranged in the well, wherein a buffer is arranged at the bottom of the well; a tractor is arranged at the top end of the well; the tractor is connected with a second guide wheel arranged at the bottom of the lift car through a steel wire rope; the second guide wheel is connected with a first guide wheel through a steel wire rope; a speed governor rope is connected with a speed governor; safety tongs and a safety mechanism are arranged at the bottom of the car frame of the lift car; a door-motor system and car top guard bars is arranged on the top end of the lift car; and a car door is arranged on one side of the lift car. According to the AC variable frequency speed regulating loading lift assembly disclosed by the invention, when a lift is overspeed; or the moving of the lift is out of control; or a hanging device is broken, in order to avoid personnel casualties and equipment damage accidents, automatic protection is performed through the safety tongs, the speed governor, a wire holder and the buffer; furthermore, a mechanical lock device, namely a door lock device is designed, and a safety switch is arranged, so that an action electrical signal of the lift car is fed back to a main program, and dangerous movement of the lift car caused by any accidental injury is avoided.
