Abstract
An anchorage assembly (100) is interconnected between a support structure (90) and a safety line (160, 161). The anchorage assembly (100) routes the safety line (160, 161) about a corner and accommodates passage of a slotted coupling device movably mounted on the safety line (160, 161).
Claims10
An anchorage assembly for routing an intermediate portion of a safety line about a corner of a support structure while accommodating passage of a coupling device, comprising:
- a first curved plate having a convex side and a concave side;
- an energy absorber attached to the concave side proximate each end of the first curved plate;
- an energy absorber attached the convex side proximate each end of the first curved plate;
- a second curved plate having a convex side and a concave side, wherein the concave side of the second curved plate is arranged to face the convex side of the first curved plate, and the second curved plate is bolted to the first curved plate;
- and
- a plurality of line supporting brackets to the convex side of anchored to the second curved plate, wherein the brackets are relatively more rigid than the energy absorbers.
