Abstract
A passenger conveyor system, such as an elevator or shuttle system, includes a drive system formed from a plurality of sequentially connected belts driven by a machine. Each of the belts is engageable with a car to move the car along a portion of the path, and adjacent belts are interconnected by a transmission. In a particular embodiment, the passenger conveyor system includes a counterweight that is also engaged with the plurality of belts. In another particular embodiment, the passenger conveyor system includes a first portion in which the belt driven car moves vertically and a second portion in which the belt driven car moves horizontally.
