Linear wheel escalator handrail drive

摘要

A direct drive wheel to handrail contact drive assembly utilizes a pair of drive rollers which contact the handrail directly. The drive rollers are powered by a single drive shaft. A pair of pressure rollers oppose the drive rollers so as to press the handrail against the drive rollers. The pressure rollers are spring biased against the handrail. The drive assembly is used to drive the handrail of an escalator or moving walkway.
