ABSTRACT:
A guiding device (30) for an elevator system (20) facilitates guiding a cab (22) along guide rails (24). The guiding device (30) includes a roller mount (34) that supports rollers (36) such that the rollers remain a fixed distance from each other. A biasing member (44) urges the mount (34) in a direction that maintains contact between the guide rail (24) and the rollers (36) and facilitates centering the guiding device (30) and the cab (22) relative to the guide rails (24).
