The present invention is directed to a shuttle device for a height safety system, the device including a first member having an inner wall defining a recess, the inner wall terminating at two sides to define a first opening. The device further includes a second member received in the recess of the first member, the second member being slidable relative to the first member to facilitate movement of the device between a locked condition and an unlocked condition. In the locked condition, the second member and a side of the inner wall define a second opening, the second opening being smaller than the first opening.

A load indicator includes a first connector, a second connector arranged such that pulling the first connector and the second connector in opposite directions applies tension across the load indicator, a fastener structured to attach the first connector to the second connector, a first spring structured to apply bias to the fastener to pull the first and second connectors together, and a moveable member disposed between the first and second connectors and around the fastener. When the tension across the load indicator is at or above a predetermined tension level, the first spring compresses allowing the moveable member to spin freely about the fastener. When the tension across the load indicator is below the predetermined tension level, the first spring pulls the first and second connectors together such that the moveable member cannot spin freely about the fastener.

A safety system includes (a) a rope or lanyard; (b) a safety hook attached to the rope or lanyard; (c) a load detection sensor retrofit to the hook without altering the structural integrity of the hook; and (d) a transmitter arranged to convey a load status signal.

An aerial lift that is interlocked with a fall-protection safety apparatus and may be further interlocked with at least one additional safety apparatus. The aerial lift is equipped with a monitoring system that is configured to detect whether a connector of a safety line of the fall-protection apparatus appears to be connected to a safety harness of a user of the aerial lift.

A tether system for a safety line has an elongate guide track and stay elements arranged to move along the guide track and be carried at spaced positions along the length of a tether line. The system is typically employed in a fall arrest or protection system mounted to a structure, having an ascent/descent ladder fixed to the structure, the system including a self-retracting safety line device including a safety line, mounted at height.

A Decelerator Packed Tether constructed with a Bungee Section and a Deployment Section in a combination of materials which, when combined as herein described, and a fall is experienced by the user, the maximum arrest force is one that will present the least amount of impact on the user conventional safety harnesses.

One aspect relates to a tensioning device comprising a pulley including a drive spindle and a pulley wheel connected to the drive spindle, a lifeline passing, in use, around the pulley wheel; a locking member configured to engage, in use, with a part of said lifeline to prevent relative movement of the lifeline with respect to the locking member in a first direction; and a handle assembly connected to the drive spindle, the handle assembly being moveable between a first, disengaged position in which rotation of the handle assembly does not cause rotation of the drive spindle and a second, engaged position in which rotation of the handle assembly rotates the drive spindle, rotation of the drive spindle rotating the pulley to move the lifeline in a second direction relative to the locking member, thereby tensioning the lifeline.

A rescue strap assembly comprising a connector, an adjuster, a mechanical advantage assembly, and a strap having a first end, an intermediate portion, and a second end. The first end is operatively connected to the connector and the mechanical advantage assembly, the intermediate portion is routed through the adjuster, and the mechanical advantage assembly is configured and arranged to engage at least a portion of the intermediate portion.

A generally flat safety hook body having a central portion with a proximal end and a hook-shaped distal end opposite the proximal end, a generally flat nose portion extending from the distal end of the central portion, and a generally flat connector portion extending from the proximal end of the middle portion. The connector portion is separated from the nose portion by an opening or gate such that the hook body has a general C shape. A flange is formed about the perimeter of the body, and a thinner web extends across to connect the inner surfaces of the flange. In one embodiment the web is flat, while in another embodiment the web is concave. In one embodiment the thickness of the flange is uniform, while in another embodiment the thickness of the flange varies to correspond to different anticipated loads along the perimeter of the hook.

A fall arrest lanyard (10) is provided for arresting the fall of a user from an elevated worksite and includes a connector (16) having a rigid frame (30) and a load bearing pin (32) extending along a longitudinal axis (34). The pin (32) has a central span (36) extending between first and second end portions (38, 40) and is mounted in the frame (30) to translate along the longitudinal axis (34) between an open position wherein at least one of the end portions (38, 40) is spaced from the frame (30) to allow a length of webbing (41) from a fall protection harness (17) to be loaded into the connector (16), and a closed position wherein the first and second end portions (38, 40) of the pin (32) are supported by the frame (30) with the central span (36) of the pin (32) being free from engagement to trap the length of webbing (41) between the pin (32) and the frame (30) for load bearing engagement with the central span (36).
