Interlocking Abrasion-Protection Device for Linemen Fall-Prevention Systems

摘要

An interlocking abrasion-protection tool for linemen fall-prevention systems has multiple belay-assistance links which are formed into a chain. The belay-assistance links act as an abrasion-protection sheath for a section of rope that runs over a sharp edge. The belay-assistance links enable a user to lower a lineman who is incapacitated or stuck without endangering other linemen or damaging the linemen-support ropes. To accomplish this, each belay-assistance link has a pair of interlocking mechanisms and multiple rigging channels. The interlocking mechanisms are positioned on opposite sides of the belay-assistance link so that multiple links can be connected in series. The rigging channels traverse through the belay-assistance device to form a raceway for the linemen-protection ropes. The rigging channels prevent the linemen-protection rope from becoming tangled while supporting a lineman.
