<p num="1"><br/>A traveller for a fall arrest system comprises a body having a passage <br/>therethrough, a slot <br/>narrower than the passage linking the passage to the exterior of the body, and <br/>a load member <br/>suitable to attach the traveller to fall safety equipment. The slot is formed <br/>between an inner gate <br/>extending outwardly relative to the passage and an outer gate extending <br/>inwardly relative to the <br/>passage, the inner gate and outer gate having respective opposed convex <br/>surfaces defining the <br/>slot between them. The traveller is arranged such that when the traveller is <br/>mounted on a support <br/>the inner gate and outer gate lie on a common radius of respective concentric <br/>circles about the <br/>support.<br/> |
