Abstract: A passenger conveyor system is arranged along a path in a racetrack fashion. Drive members associated with lateral edges of each pallet step surface move with the pallets through straight sections of the path to avoid relative movement between the pallets and adjacent structure. During turnaround sections, where the pallets are beneath a floor surface, the drive members move relative to each other, with one set of drive members becoming temporarily disconnected from each other, to permit the pallets to make a transition and a turnaround. In the illustrated example, a drive mechanism cooperates with at least one set of the drive members to transmit a motive force to propel the pallets along the path.

Abstract: An escalator drive machine includes a motor output sheave connected to a drive motor through a belt reduction assembly including a main output sheave. A drive belt extends from the belt reduction assembly and is guided along a plurality of guide sheaves to engage the step chain and propel the escalator tread plates. In addition, by locating a pinch roller adjacent the handrail, the drive belt and handrail can be pinched together to provide a motive force to the handrail. The drive belt thereby synchronously drives the handrail. In another embodiment the drive machine includes a counter-rotating motor to drive a drive belt on each side of the escalator system.
