Abstract

A fall arrest assembly that includes a rotational drum, at least one pawl and a catch is provided. The rotational drum is configured to rotate in response to a movement of a lifeline. The least one pawl is in rotational communication with the rotational drum. The at least one pawl is further configured to pivot about a pivot connection in response to select rotational velocities of the rotational drum. The at least one pawl is also configured to engage the catch when the at least one pawl pivots in response to the select rotational velocities of the rotational drum to stop the rotation of the rotational drum and movement of the lifeline. An elastic bushing for each pivot connection is also used. Each elastic bushing is positioned about an associated pivot connection of an associated pawl. The elastic bushings deform in shape as an associated pawl engages the at least one portion of the catch.

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority to U.S. Provisional Application Ser. No. 61 / 196,716, entitled “Climb Assist System,” filed on Mar. 2, 2009, and Provisional Application Ser. No. 61 / 167,459 entitled “Climb Assist System,” filed on Apr. 7, 2009, which are both incorporated in their entirety herein by reference. This Application is further related to U.S. Utility application Ser. No. ______ (Attorney Docket No. 221P249USU1), entitled “Climb Assist System,” filed on even date herewith which is also incorporated in its entirety herein by reference.BACKGROUND[0002]The ability to service devices that are elevated requires a system for getting a service technician to the device. One common system used to reach elevated locations is a ladder. However, when the distance to reach the device is significant, the use of a ladder is restricted to only those individuals that are physically capable of climbing the distance of the ladder. Safety issues als...
