摘要： An escalator having a conveyor constructed of rigid, pivotally interconnected toothed links, step axles, steps on the step axles, axle rollers on the axles, and step rollers on the steps. The guide arrangement for the conveyor includes a truss having axle and step roller guides. The guide portion of the truss includes movable, free-floating, self-adjusting, upper and lower turnarounds guided for rectilinear movement, and a fixed intermediate portion. Sliding joints which permit mis-alignment without binding interconnect the movable and fixed portions of the axle and step roller guides.
