Abstract
A height safety system includes an elongate semi-rigid element (310) suspended from its end under tension between a pair of fixed anchors and is supported by intermediate guides (331). Shuttle means (360) are installed on the element (310) and are adapted for movement therealong between the fixed anchors. The shuttle means (360) are provided with attachment devices (365) for receiving a suspended load or a personnel safety line. The intermediate guides (331) are designed to grip the element (310) with a predetermined clamping force that allows limited slippage of the element (310) therethrough in response to an applied tensile load exceeding the clamping force. Slippage no longer occurs when the tensile load equals the predetermined clamping force. In this way, the tensile load is partially transferred to an adjacent span of the element (310).
