Abstract

An assembly for controlling a vertically extending member includes a device (22) having a stop member (34) and a speed control member (36) for controlling movement of the vertically extending member such as an elevator load bearing member (32) during a roping procedure. In a disclosed example, the stop member (34) is biased into a stop position where the vertically extending member (32) is locked between a brake pad (60) and a guiding member (54) so that the vertically extending member (32) cannot move relative to the device (22). An example input member for moving the stop member (34) out of the stop position comprises a foot pedal (70) that can be manipulated to control a position of the stop member (34). Absent manual manipulation of the input member, the stop member (34) prevents movement of the vertically extending member (32). In a disclosed example, a speed control member (36) comprises a pad (80) that selectively engages a vertically extending member (32) responsive to manual manipulation of a handle (84) for moving the pad (80) relative to a base (40) of the device (22).
