Provided with wall-mounted supports, this kind of traction machine has its bearing structure consisting of four detachable drag links and have external rotor construction. The traction sheave is directly mounted on rotor yoke. Repulsion rectangular brake is fixed on upper drag link with rectangular cross-section, and it has unique design that makes it compact and light. Traction rope groove can be arranged in the middle or on one side. When the rope groove is arranged in the middle, double rope groove can be used so as to double the life of traction sheave. The traction machine can be installed on the top of the shaft way or at the bottom of the shaft way, and has handwinding function.
