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.

Method of installing a vertically extending member in an elevator system

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

A clamp device () includes a plurality of arms (). One of the arms supports a securing member (). The other arm includes a curvilinear surface () that directly engages a curved wall of an article at a location in line with a centerline of the securing member. The curvilinear surface () allows for the clamp device to reliably engage an article having a curved wall for a lifting operation. One example use of a disclosed example device is for lifting tubes associated with a hydraulic elevator system.
