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

A traveller for a fall arrest system comprising:
- a body having a passage therethrough, a slot narrower than the passage linking the passage to the exterior of the body, and a load member suitable to attach the traveller to fall safety equipment, the slot being formed between an inner gate extending outwardly relative to the passage and an outer gate extending inwardly relative to the passage, the inner gate and outer gate having respective opposed convex surfaces defining the slot between them, the traveller being arranged such that when the traveller is mounted on a support the inner gate and outer gate lie on a common radius of respective concentric circles about the support.
A support for a safety line in a fall arrest system comprising a support section suitable for retaining a safety line and attachment means for attaching the support to a structure, the supporting section and the attachment means being connected by an arm, the arm having a tangential section narrower than the safety line and extending substantially tangentially relative to a safety line retained in the supporting section.
A fall arrest system comprising a safety line, at least one support and a traveller, in which the support comprises a support section retaining the safety line and an attachment means for attaching the support to a structure, the support section and attachment means being connected by an arm having a tangential section narrower than the safety line and extending substantially tangentially relative to the safety line, and the traveller comprising a body having a passage therethrough, a slot narrower than the safety line linking the passage to the exterior of the body and a load member suitable to attach the traveller to fall safety equipment, the slot being formed between an inner gate and an outer gate having respective opposed surfaces defiming the slot between them, the inner gate and outer gate being arranged such that when the traveller is mounted on the support within the passage the tangential section of the arm can pass through the slot.
