20120132481 | Fall Arrest System - A fall arrest safety system has a traveller arranged to travel along a safety line and including a securing arrangement deployable in response to a fall event to secure the traveller in fixed position on the safety line. An energy absorber device is connected intermediately between the traveller and the user, the energy absorber device including a plastically deformable energy absorber deployable in response to a fall event to plastically deform from a stowed orientation to a deployed orientation. The energy absorber may have a coil-form portion and an elongate tongue portion extending in a linear direction at the periphery of the coil-form portion, the elongate tongue portion of the energy absorber being arranged to extend to project from the housing for connection to a karabiner, lanyard or other connection device. | 05-31-2012 |
20120217092 | Safety Line Traveller - A traveller for safety line for a fall arrest system has a slot extending to the exterior of the traveller and a safety line locating shuttle provided on-board the traveller wherein the safety line locating shuttle is movable relative to the slot along a predetermined path in a direction across the slot. This aids in accurate positioning of the safety line with respect to the traveller. The slot can be defined between opposed slot edges which are movable relative to one another to reconfigure the slot. | 08-30-2012 |
20120267194 | Bracket Fixing For A Safety Line - A bracket fixing for securing a safety line to a structure, has a safety line receiving portion and a fixing portion connected to the safety line receiving portion, the fixing portion having a captive mechanical fixing, arranged to engage with and secure the bracket to the structure. | 10-25-2012 |
20130193293 | Vacuum Anchor System - A vacuum anchor for securing a fall protection system to a surface has a gas inlet to receive pressurised gas from a gas container and generates a vacuum to secure the anchor to a surface. An attachment enables a fall protection system to be connected to the anchor, the attachment being rotatably mounted to the anchor. A container mounting device is provided for mounting the gas container to the anchor in connection with the gas inlet, the container mounting means being rotatable with the rotatable. Alternatively or additionally, the gas inlet is coaxial with the axis of rotation of the attachment means. | 08-01-2013 |
20130248291 | Rescue Descender System - A descender system, typically for use in a fall arrest system, for enabling a suspended body to be lowered includes a rotatable descent line drum, and a release element arranged in a restraint configuration to inhibit the descent line from being deployed and in a release configuration to permit the descent line to be deployed. A rotating brake applies a braking force to the rotatable descent line drum; a gear train connects the brake to the drum. The gear train is provided in a substantially watertight sealed space. Typically, a substantially watertight seal is provided between a backplate of the rotating drum and a chassis of the device. Typically, the substantially watertight seal is of a material that is deformable/compressible, preferably at temperatures at or below −20 Celsius. | 09-26-2013 |
20140008148 | Safety Line Traveller and Support - 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. | 01-09-2014 |
20140041960 | Rescue Descender System - A descender device, typically for use in a fall arrest system, for enables a suspended body to be lowered, and includes a descent line and a release element to be actuated by a person. The release element is arranged in a restraint configuration to inhibit the descent line from being deployed and in a release configuration to permit the descent line to be deployed. A restraint arrangement is arranged prior to deployment of the descent line, to clamp or pinch a length of flexible line thereby to inhibit deployment of the descent line, the restraint arrangement being reconfigurable upon release of the release element to permit the descent line to be deployed. | 02-13-2014 |
20150217151 | Fall Arrest System Safety Device - A safety device for use in a fall arrest system, has a safety line drum mounted for rotation and a speed responsive engagement mechanism responsive to the speed of rotation of the drum, which is activated above a predetermined rotational speed of the drum to deploy an energy absorber. A rotational transmission member (which may be in the form of a shaft) is coupled, via the speed responsive engagement mechanism, when activated, to rotate with the drum. The energy absorber is deployed in response to operation of the rotational transmission member. The speed responsive engagement mechanism may be mounted intermediate the drum and the energy absorber for ease of replacement. | 08-06-2015 |
