Drive device of the bull-wheel of a single carrying-hauling rope chair lift with fixed rope grips

摘要

A bull-wheel of a fixed carrying-hauling rope chair lift is driven by a geared motor mechanism having a coaxial shaft line extending perpendicularly to the bull-wheel in a substantially vertical direction. The geared motor mechanism is composed of an electric motor and a mechanical speed reducer forming two independent modules arranged on each side of the bull-wheel, which is fitted on a movable carriage to ensure mechanical tensioning of the rope.
