CA 2280326

A height safety system comprises an elongate semi-rigid element (310) suspended from its ends under tension between a pair of fixed anchors (not shown) and is optionally supported by intermediate guides (331). Shuttle means (360) are installed on the element (310) and are adapted for movement therealong between said fixed anchors. The shuttle means (360) are provided with attachment means (365) for receiving a suspended load or a personnel safety line. The intermediate guides (331) may be so 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 said 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).

L'invention concerne un système de sécurité d'altitude comprenant un élément allongé semi-rigide (310), suspendu sous tension par ses extrémités entre deux dispositifs d'ancrage, cet élément pouvant éventuellement reposer sur des rails intermédiaires (331). Des organes coulissants (360) sont installés sur cet élément (310), ces organes étant conçus pour coulisser le long dudit élément entre les dispositifs d'ancrage. Ces organes coulissants (360) sont pourvus d'attaches (365), destinées à recevoir un poids en suspension ou un câble de sécurité pour le personnel d'entretien. Les rails intermédiaires (331) peuvent être conçus pour saisir l'élément (310) avec une force de serrage prédéterminée, ce qui permet de limiter tout glissement dudit élément (310) le long des rails, en réponse à l'application d'un effort de traction supérieur à ladite force de serrage. Il est donc impossible pour ledit élément de glisser si l'effort de traction correspond à la force de serrage prédéterminée. Ainsi, cet effort de traction est partiellement transféré vers une travée adjacente dudit élément (310).
