A fall arrest assembly includes a pole that is mountable to a tree. A pair of mounts is provided and each of the mounts is mountable to the tree. Each of the mounts engages the pole for mounting the pole to the tree. A body harness is provided that is wearable on a user. A slide is slidably positionable on the pole when the pole is mounted to the tree. The slide frictionally engages the pole when more than a trigger force is exerted on the slide such that the slide resists sliding on the pole. A lanyard is removably attachable between the body harness and the slide. The slide is exposed to a force that exceeds the trigger force when the lanyard supports the weight of the user. In this way the slide inhibits the user from falling rapidly to the ground when the user falls from the tree stand.

An anchorage assembly including first and second plates that are slidably movable relative to each other, each plate comprising an upper head with an outwardly-extending flange, and the first plate including at least one spreader ramp positioned in an upper portion of the first plate.

A fall control system is described. The fall control system comprises an elongate guide rail extending along an axis, one or more than one trolley for moving along the elongate guide rail, a tether attached to the trolley at a first end, a second end of the tether for attaching to a user, and a speed control system for controlling a speed of the trolley along the elongate guide rail. The speed control system comprises one or more than one speed control track attached to the elongate guide rail and extending along the axis, a background speed controller coupled to the trolley and engaged with the one or more speed control track when the speed control system or the trolley is in a travelling orientation and controlling the speed of the trolley along the elongate guide rail to not exceeded a maximum walking speed.

A vertical fall arrest safety device travels along a rail of a vertical track and is configured for quick attachment and detachment anywhere along the rail. The device has a mounting body having side rail engagements configured for slidably engaging behind the edges of a rail of the vertical track in use. The engagements are spaced and staggered so as to receive the rail therebetween when the mounting body is at an angle, and then slidably attach to the rail when the mounting body is twisted into alignment with the rail. The device also has a lever pivotally coupled to the mounting body at a fulcrum. As such, when a downward force is applied to a connection point of a distal end of the lever, an opposite distal end of the lever frictionally engages the rail.

A safety check apparatus and method for testing a lanyard system prior to entering a challenge course. The apparatus comprises a track arranged at an entrance of the challenge course. The track includes a first position and a second position above a supporting surface. A moveable member is supported by and displaceable relative to the track. The track is connected to a course track that traverses the challenge course such that the moveable member is displaceable therebetween. A lanyard is attached to the moveable member and extends a length from the moveable member. A user harness is coupled to the lanyard. When at least a portion of a user's weight is supported by the harness, the connection point between the harness and the lanyard is positioned higher above the supporting surface at the second position of the track than at the first position of the track.

A system for physical mobility activity of a person includes at least one fixed support member and at least one contact member to be worn by a person in motion. The support member and the contact member include at least one support surface and at least one contact surface, respectively. The support surface and the contact surface constitute the respective components of a hook-and-loop fastening connection including of hooks and loops, wherein the hooks have hook stems and hook openings. The hook openings on the support surface or contact surface in question are at least substantially all situated at the same side of the hook stems in question, when considered in a first direction parallel to the support surface or contact surface in question.

A module for a fall protection system comprises a structural sheet having a ridge and an attachment panel extending laterally therefrom and one or more attachment sections. The attachment panel can be secured to a structure. The module has one or both of: (i) an anchorage connector attached to the ridge at an attachment section; and (ii) a rail clamp having a sleeve portion and a leg portion attached to the ridge at an attachment section; a rail extending through and supported by the sleeve portion; and a slider supported on the rail. The slider is slideably movable along the rail and has a slider anchorage connector. The ridge may be received in a flashing ridge having a flashing extending laterally therefrom to provide coverage for the attachment panel. A person may be attached to the anchorage connector or the slider anchorage connector via a safety line.

A fall control system is described. The fall control system comprises an elongate guide rail extending along an axis, a trolley for moving along the elongate guide rail, a tether attached to the trolley at a first end, a second end of the tether for attaching to a user, and a speed control system for controlling a speed of the trolley along the elongate guide rail. The speed control system comprises one or more than one speed control track attached to the elongate guide rail and extending along the axis, a background speed controller coupled to the trolley and engaged with the one or more speed control track when the speed control system or the trolley is in a travelling orientation and controlling the speed of the trolley along the elongate guide rail to not exceeded a maximum walking speed. The speed control system also includes a speed controller coupled to the trolley and engagable with the one or more than one speed control track, the speed controller displaceable from a first position when the speed control system or the trolley is in the travelling orientation, and the speed controller is not engaged with the speed control track, to a second position when the speed control system or the trolley is in a falling orientation and the speed controller is engaged with the speed control track. The speed controller for controlling the speed of the trolley along the guide rail in the falling orientation to not exceed a maximum fall speed.

The present application relates to the technical field of linkage mechanisms, and provides a linkage operation assembly, a fall protection device and a fall protection system. The linkage operation assembly includes a fixed main body configured to be installed on an outer support surface of a rail and move along the rail; a second wheel body assembly installed on the fixed main body for rolling along an inner support surface of the rail and including a second wheel set and a drive rotary shaft; a third wheel body assembly installed on the fixed main body for rolling along an inner support surface of the rail and including a third wheel set and a driven rotary shaft; and a linkage member disposed between the drive rotary shaft and the driven rotary shaft. When the drive rotary shaft of the linkage operating assembly rotates, the second wheel set is driven to rotate, and the driven rotary shaft and the third wheel set are driven to rotate through the linkage member. Therefore, during the installation process of the linkage operation assembly, only the drive rotary shaft needs to be rotated to switch the state of the linkage operation assembly, so as to facilitate the installation of the linkage operation assembly. Similarly, when the linkage operation assembly is disassembled, only the drive rotary shaft needs to be rotated.

A system for monitoring a fall arrest device, where said fall arrest device is a lifeline of a flexible rope or track type, comprising: a first sensor (15) for measuring the oscillations of said fall arrest device; a control unit (13) being electrically connected to said first sensor (15); said control unit (13) being electrically connected to a control centre (45); said control centre (45) being designed to evaluate whether an event selected from among a series of predefined events has occurred, based on the measurements carried out by said first sensor; in the case of a positive outcome said control centre (45) being designed to warn of the occurred event, with a signal.
