Abstract: 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.

Abstract: A fall arrest anchor trolley for arresting the fall of a user. In one embodiment, the invention can be a system for arresting movement of a worker after falling from an elevated work surface comprising: a rail; a trolley in rollable contact with the rail, the trolley having a body, a brake sub-system, and a plurality of wheels, the brake sub-system comprising 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 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 biasing the brake sub-system into the free state.

Abstract: A fall arrest anchor trolley for arresting the fall of a user. In one embodiment, the invention can be a fall arrest trolley comprising: a body a brake sub-system, and a plurality of wheels rotatably coupled to the body, wherein bottoms of the plurality of wheels collectively define a rolling plane; the brake sub-system comprising 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 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 rolling plane; and (2) an arrest state in which at least a portion of the brake pad is located within the rolling plane; the resilient element biasing the brake sub-system into the free state.

Abstract: A trolley and fall arrest safety system is disclosed for movement along an elevated track to support a person who has fallen off of a structure adjacent the track. The trolley is arranged to roll on along a surface of the track in a longitudinal direction to suspend a person therefrom in the event that the person falls from an elevated position adjacent the track. The trolley includes an immobilizing assembly including a flexible strap. The strap is arranged to be pulled by the suspended worker to releasably fix the trolley at a longitudinal position on the track, so that the person can swing himself/herself to move the trolley to a desired safety position.

Abstract: An enclosed track system comprising an enclosed track having at least one curve and a trolley for negotiating the curve. The trolley includes an externally located drive section and a rolling section having first and second roller portions located within the track. The first roller portion includes rollers for rolling on flange portions of the track. The second roller portion includes a driven wheel and a pair of support rollers. The driven wheel rolls on an inner surface of the top of the track. The pair of support rollers roll on flange portions of the track and are mounting on respective rods for pivoting action about vertical axes. The drive section includes a motor, a drive sprocket and associated chain for positively driving the driven wheel. The drive section also includes an articulated joint coupling the first and second roller portions together.
