Patent abstract
A fall arrest safety device for workers on transmission towers and the like includes a “matched” safety rail and brake trolley. The rail has a profile which includes a non-symmetrical profile portion and the trolley has a passageway of complimentary profile so that the trolley cannot be installed on the rail up-side down. A full body harness worn by a user of the device is clipped to the trolley and the trolley incorporates a brake which is spring-biassed into frictional engagement with the rail. The brake can be disengaged from the rail only by the user deliberately overriding the biassing effect.
