A fall arrest device comprises a guide for a track member which, in use, passes through the device, a cam member including a cam portion, and a clutch responsive to at least one of the relative speed and relative acceleration of the fall arrest device and the track member. The clutch serves to determine when the relative speed and/or acceleration is at least a predetermined value. The clutch includes a trigger arm connecting to the cam member so as to move the cam portion of the cam member toward the guide so as to lock the track member between the cam member and the guide when at least the predetermined value is attained.

An improved safety system in accordance with the disclosed and claimed concept connects directly with the rail and advantageously provides both a fall resistance apparatus as well as a fall protection apparatus. The fall resistance apparatus provides a support that is movably situated on the rail and that can be manually grasped by the worker during the maintenance operation and which provides physical support in all directions to the worker. The fall resistance apparatus thus resists the likelihood that a fall will occur. In the unlikely event of a fall, the fall protection apparatus connects the worker directly to the rail and supports the worker from the rail at a location spaced above the floor, thus protecting the worker from injury in the event of a fall.

The present system for fall restraint includes a mounting frame connected to a trigger mechanism and firing blocks, with a trigger cable extending through apertures in the mounting frame and trigger mechanism. Sudden movement by a user, such as a fall, actuates the trigger mechanism to trigger the firing blocks. The firing blocks are loaded with anchors and firing cartridges. Triggering the firing blocks causes the cartridges to fire, propelling the anchors into an anchoring surface, such as a roof. Because the user is connected to the trigger cable, once the anchors deploy the user is anchored to the roof and their fall arrested.

A rigid rail assembly for a fall protection system comprises a rigid rail segment and a hanger. The rail segment comprises an upper portion defining an elongate slot and a lower portion. The hanger includes a hanger body adapted to be connected to a support member and a hanger coupling member extending downwardly from said hanger body and which is adapted to be received in the rail segment slot. The rail segment lower portion has opposed elongate side walls extending downwardly and outwardly and a flange extending inwardly from each of said side walls. The flanges define a track for the wheels of a trolley.

The present invention is directed to a climbing wall comprising a climbing surface and a climbing assistance assembly that provides a disabled child with an opportunity to utilize the climbing wall. The climbing assistance assembly comprises a track mounted above at least a portion of the climbing surface and spanning at least a portion of the length of the climbing surface. A trolley, from which a rope is suspended, is configured to travel along the track. The rope is coupled both to the trolley and to a harness. The climbing assistance assembly may further include a fall arrest device configured to lower an end of the rope coupled to the harness from an elevated position to a rest position in a controlled manner. Because the trolley is configured to travel with a user wearing the harness as the user traverses a length of the climbing surface, the fall arrest device is positioned substantially directly above the user throughout the user's climbing experience, ensuring that if the user falls, the descent will occur in a safe and controlled manner.

A fall arrest system for arresting the fall of a user. The system may arrest movement of a worker after falling from an elevated work surface. The system may include a rail; a trolley having a body in rollable contact with the rail, a brake sub-system, and a plurality of wheels. The brake sub-system may include a brake rod, a brake pad connected to the brake rod, a lanyard connector connected to the brake rod, and a resilient element. The brake rod may be slidably coupled to the body so that the brake sub-system is alterable between: (1) a free state in which the brake pad is spaced a distance above the rail; and (2) an arrest state in which at least a portion of the brake pad frictionally engages the rail. The resilient element may bias the brake sub-system into the free state.

A height safety trolley and modular rigid rail system for construction and maintenance personnel working at height is designed to allow continuous, smooth and fail-safe operation, for fall restraint and fall arrest, rope access and abseil. The height safety trolley has a connection arm, a clip body and a main chassis operably interfacing a rail engagement mechanism, movable between a rail engagement position to engage a rigid rail, and a disengagement position to disengage the rigid rail. The rail engagement mechanism may comprise integral pivot arms which close simultaneously inwards to engage the rigid rail and outwards to disengage the rail. As such, the trolley is easily and safely attachable and detachable at any position along the rigid rail.

A fall protection safety rail system has a rail defining a trolley channel therein. The rail also defines exterior side and top attachment channels. The system has a support which engages the side attachment channels to support the rail either side thereof. One type of support may comprise a hanger channel bracket having a web and flanges spaced apart so that the flanges fit against the sides of the rail. The side and top attachment channels may be dual-purposed for connecting rail sections together using respective splices. Furthermore, the side attachment channels may overlap with the trolley channel along a vertical axis but not along a horizontal axis to confer a low profile rail configuration having enhanced resilience and capability.
