Abstract
A lifeline safety system is employed for anchoring a retractable lifeline system to a pre-cast deck panel to provide fall protection for workers. The lifeline anchor assembly employs a pair of clamp bars which are adapted and positionable for engaging opposing lifting notches of the pre-cast panel. The retractable lifeline is received in mounting shoes which are mounted to the top of a frame which extends across the top of the panel.
Claims21
An assembly for anchoring a safety lifeline to a pre-cast concrete panel having lifting notches disposed at opposite sides thereof comprising:
- frame means for forming a frame having a first end and an opposite second end and defining a longitudinal axis through said first and second ends;
- shoe means mounted to said frame means for receiving a lifeline;
- securement means for securing said lifeline in said shoe means;
- first clamp means mounted to said frame at said first end and comprising a first engagement member extending transversely to said axis substantially the width of said frame means for engaging a lifting notch;
- second clamp means mounted to said frame at said second end and comprising a second engagement member extending transversely to said axis substantially the width of said frame means for engaging a second lifting notch;
- and
- lock means for locking said first and second clamp means clamped relationship at said notches so that said lifeline is anchored to said panel.
