  • Method of installing a vertically extending member in an elevator system
    Patent number: 10364128
    Abstract: An assembly for controlling a vertically extending member includes a device having a stop member and a speed control member for controlling movement of the vertically extending member such as an elevator load bearing member during a roping procedure. In a disclosed example, the stop member is biased into a stop position where the vertically extending member is locked between a brake pad and a guiding member so that the vertically extending member cannot move relative to the device. An example input member for moving the stop member out of the stop position comprises a foot pedal that can be manipulated to control a position of the stop member. Absent manual manipulation of the input member, the stop member prevents movement of the vertically extending member. In a disclosed example, a speed control member comprises a pad that selectively engages a vertically extending member responsive to manual manipulation of a handle for moving the pad relative to a base of the device.

  • Assembly for roping an elevator
    Patent number: 9604823
    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).
