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).

[ In accordance with the present invention, I claim:] [1.]1. A height safety system comprising a flexible elongate element, said element being pretensioned between support brackets at intervals to stiffen its linear form, and shuttle means coupled to said elongate element adapted for movement therealong, said shuttle means including attachment means for receiving a suspended load or a personnel safety line;said elongate element having primary and secondary track formations independent from each other, said primary track formation providing a continuous path along which said shuttle means is able to traverse without interruption, and said secondary track formation providing attachment points for said support brackets at any point along the extent of the element without obstructing said primary track formation.
