Traction Gearless Elevators
The Traction Gearless Elevator utilizes a gearless machine, ropes, and a counterweight. The main guide rails are mounted on the side of the elevator car and two additional guide rails are mounted on one side or the rear for the counterweight. The gearless machine is generally located above the hoistway.
