Traction Machine Room Less (MRL)




Canton Elevator’s Traction MRL application replaces traditional hydraulic equipment with a gearless machine, ropes and counterweights.  Main guide rails will be installed on both sides of the elevator car with an additional set of counterweight rails being mounted either in the side or rear of the hoistway.  A GL Series AC Permanent Magnet Gearless Machine mounted on machine beams in the overhead eliminates the need for a machine room therefore resulting in lower construction cost.
