ABSTRACT:
A handrail-drive for an escalator or moving walk drives the handrail through frictional contact with an outside surface of the handrail. Press-on rollers engaging the inside of the handrail may be employed to press the handrail against a drive-wheel of the drive. The force of the rollers may be adjustable. The drive-wheel may include a gas-filled tire on a rim and can be driven by a motor, a step-chain wheel, or a step-chain drive.
