Safety system for person working on sloping surface or steep bank has anchoring point for safety wire, and incorporates radio-controlled motor-driven winch

摘要

The end of the safety wire may be attached to the person and the anchor point may incorporate a winch driven by an electric motor. The person carries a radio transmitter which sends control signals to a radio transmitter on the winch, to make it let out the wire at a slow rate or reel it in as required.
