FALL ARREST SUPPORT

摘要

A fall arrest system has a top anchorage bracket (1), a bottom anchorage bracket (2) and a cable (3) between the brackets. Fixture ends (12, 22) of the brackets carry bosses (13, 23) in their bottom and top edges (14, 24) respectively. Cable tension pulls the distal ends of the brackets towards each other about the bolts B and the bosses react with the corner of the pylon. The bracket end (15) is dimensioned such that in the event of a fall and loading of the cable, the bracket (1) deforms plastically, peeling away from the face F. The bottom anchorage bracket (2) has an arm (25) with a bore for a clamp bolt (31), carrying a load transfer bracket (32) and a clamp nut (34). The bolt is engaged in a slot (35) in a slotted limb (36) of the bracket (32). Above the limb, the load transfer bracket (32) is integrally connected via a thin tongue (37) to a sleeve (38) locating the end of the cable. The cable (3) extends through the sleeve to a swaged on collar (40). A tensioning device is used to draw down the limb (36) and tension the cable, whereupon the brackets (2) and (32) are clamped together.
