Zusammenfassung: | A safety line traveller (3) for use in fall safety equipment has a longitudinal bore (24) through which the safety line (1) passes. The safety line (1) is supported by intermediate supports (2) having a tubular support section (4) through which the safety line (1) passes supported by a narrow arm (5). In order to allow the traveller (3) to pass along the safety line (1) over the intermediate supports (2) automatically the bore (24) is sufficiently large to pass over the support section (4) of the intermediate support (2) and the body of the traveller (3) is broken by a slot (25) connected to the bore (24), the slot (25) being wider than the arm (5) of the intermediate support (2) but narrower than the safety line (1). The traveller (3) has a centre of gravity located so that the traveller (3) automatically rotates about the safety line (1) due to gravity into an orientation where the slot (25) is in line with the arm (5). The traveller (3) is connected to personnel fall safety equipment through a flexible lanyard connected to a load handle (23) on the traveller (3). The load handle (23) is pivotally connected to the traveller (3) so that the traveller (3). The load handle (23) is pivotally connected to the traveller (3) so that the traveller (3) can rotate about the safety line (1) independently of the forces applied to the traveller (3) through the load handle (23). Further, the traveller (3) has cam members (28) and the intermediate support (2) has guide surfaces (12), the cam members (28) and guide surfaces (12) being arranged so that if the slot (25) and arm (5) are not correctly oriented, the cam members (28) and load surfaces (12) will cooperage as the traveller (3) moves towards the intermediate support (2) to rotate the traveller (3) about the safety line (1) until the slot (25) and arm (5) are correctly aligned. |
