Abstract: A traveller for a fall arrest system including a body having a bore and a slot narrower than the bore linking the bore to the exterior of the body. A load member is connected to the body for pivotal movement relative to the body and suitable for attachment to fall safety equipment. The body has a center of gravity positioned so that when the traveller is supported on a safety line passing through the bore, the body will be urged by gravity to rotate about the safety line towards a position in which the slot has a predetermined orientation relative to the safety line.

Abstract: A removable load transfer device 100 for use in height safety apparatus comprises: spaced-apart rotary members 101, 102 supported for rotation with respect to each other about a common axis of rotation along which the axle extends continuously between the rotary members; a slipper 110 defining a space 150 for receiving elongate element 250 on which the device 100 travels; an attachment 300 for attaching a load to the device 100, and an access for element 250 includes at least one notch 117, 118 in the hub of each rotary member 101, 102 and attachment 300 includes a moveable link assembly operable between blocking and release positions with respect to notches 117, 118 by said element 250, without movement of the rotary members away from each other along the common axis, such that the attachment prevents unintended release of the load from the device.

Abstract: A fall arrest device (100) for use on an elongate support (180) including locking cams (132, 133, 134, 135) embodied by first and second independent actuable cam elements (133, 135), said cam elements (133, 135) being biased by a bias (132, 133, 134, 135) into locking engagement with the elongate support (180) and being actuated by a common arrester (128) in response to a sudden change in load experienced by the device (100) such that said first cam element (133) traps the elongate support (180) relative to a chassis (102) when the elongate support (180) slopes in a first direction and such that said second cam element (135) traps the elongate support (180) relative to said chassis (102) when the elongate support (180) slopes in a second direction.

Abstract: A support for an elongate element comprises a body portion adapted to restrain a supported elongate element against lateral movement. The body portion has a plurality of partial shells extending therefrom, each partial shell having a cross section substantially conforming to a part of the profile of the elongate element to be supported. Adjacent partial shells extend in opposing lateral directions relative to the longitudinal axis of the support. The support may be a split cylinder having a helical groove extending longitudinally of the support, the width of the groove 16 being at least equal to the diameter of the elongate element to be supported.

Abstract: A personal safety device (10) adapted for longitudinal movement relative to an elongate support element (50) comprises a body (11) having a bore (12) for receiving the element (50), a slipper (20) mounted on the body (11) the slipper (20) having a surface (21) oriented substantially parallel to the longitudinal axis of said bore (12), and connector (30) connected to the slipper (20) and being adapted at its other end (31) for connection to a personal safety harness. Slipper (20) is movable between first and second positions in response to sudden loading of the connector (30). In the first position, surface (21) allows free passage element (50) through the bore (12). When slipper (20) is in the second position, surface (21) clamps element (50) firmly to body (11).

Abstract: 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).
