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.

First claim

We claim:

1. A method of installing an elongated member in an elevator system, comprising the steps of:
(A) positioning a device in a selected position relative to at least one component of the elevator system, the device comprising:
a base;
a speed control member that is moveable relative to the base;
a stop member biased into a stop position in which the stop member is configured to prevent movement of the elongated member relative to the base absent an input force applied by a user to overcome the bias;
a first manual input member comprising one of a foot pedal or a handle configured to be manually moved by the user to overcome the bias and move the stop member out of the stop position; and
a second manual input member comprising the other of the foot pedal or the handle configured to be manually moved by the user to control a position of the speed control member;

(B) manipulating the elongated member into a position wherein a portion of the elongated member is engaged by the stop member in the stop position;
(C) selectively manipulating the first manual input member to overcome the bias and move the stop member out of the stop position to thereby allow a selected amount of movement of the elongated member relative to the device;
(D) installing the elongated member into a desired installed position relative to elevator system components; and
(E) selectively manipulating the second manual input member to move the speed control member to selectively contact the elongated member and to control the speed of movement of the elongated member during at least some of the selected amount of movement.

2. The method of claim 1 , wherein the stop member has an exterior contour corresponding to an exterior of the elongated member to avoid deflecting the elongated member when the elongated member is engaged by the stop member in the stop position.

3. The method of claim 2 , wherein the elongated member comprises a flat belt elevator load bearing member and the stop member comprises a generally planar contour for engaging the flat belt.

4. The method of claim 2 , wherein the elongated member comprises a round rope elevator load bearing member and the stop member comprises a concave contour for engaging a correspondingly convex exterior of the round rope.

5. The method of claim 1 , wherein the stop member locks the elongated member relative to the base and prevents any movement of the elongated member relative to the base absent an input force applied by a user to overcome the bias and move the stop member out of the stop position.
