Abstract
An energy absorber for a horizontal lifeline protection system is provided. The energy absorber comprises a pair of independent shock absorbing units of similar construction. Each unit comprises a strip of woven webbing material and a strip of tear-ply webbing material. Each pair of corresponding ends of these strips are secured to each other and to a ring for securing to a portion of the horizontal lifeline fall protection system. The corresponding pairs of rings at each end are secured to each other. The woven webbing and tear-ply webbing of the units are folded and encased within a tearable envelope. The absorber is constructed so as to be secured to a horizontal lifeline within a fall protection system so that when a predetermined force is applied to the rings, the envelope tears and the tear-ply webbing separates, resulting in an overall elongation of the absorber. In the event the tear-ply webbing separates completely, the remaining force is applied to the woven webbing.
