A case or support cradle (10) for a fall arrest device has a shape or configuration enabling rolling of the case or cradle (10) along an arcuate path. The rollable case or cradle (10) allows the fall arrest device received therein to smoothly follow a user's movements around a work site, thereby protecting the device from damage due to dragging or scraping along a floor surface.

Locking systems and method of manufacturing the same are provided. A locking system for fall protection includes a braking lever. The braking includes a shock absorber. The shock absorber includes a plurality of coils. The shock absorber also includes a plurality of breakaway interfaces coupling the plurality of coils together. Each of the plurality of breakaway interfaces are configured to decouple two of the plurality of coils at a different force. At least one of the breakaway interfaces defines at least one deformable finger defined on one of the plurality of coils of the shock absorber interfacing with another coil of the shock absorber.

A locking system is provided for fall protection. The locking system includes a housing. The housing defines a guide path through which the housing is slideably attached to a guide member. The locking system also includes a braking lever having a braking surface and an attachment end. The braking lever is configured to rotate so as to allow a braking surface to engage the guide member. The locking system further include a locking lever that is rotatably coupled to the braking lever. The locking lever is rotatable such that it rotates from an unlocked position to a locked position. In the unlocked position an activation end of the locking lever is positioned in a first location that is proximate to the attachment end and in the locked position the activation end is positioned in a second position distant to the attachment end.

A multifunction NFPA escape and ladder belt having multiple functions for firefighter and rescue worker work. The belt includes a front buckle and right and left side buckles, straps coupling the left and right side buckles to the front buckle and to one another. At least one of said straps includes a stitched loop portion formed with a stitching pattern configured to fail, and for the loop portion to unfold, when the side straps are under a sufficient tension load exceeding the breaking strength of the stitching pattern; that failure will occur before a structural failure in any other element or component of the belt.

A harness includes a belt and two separate thigh loops, in which at least one element selected from the belt and the thigh loops includes a first lower support strip to which at least, firstly, a first portion of an open coil and, secondly, a first upper cover strip are bonded. The at least first portion of the open coil is positioned between the lower support strip and the upper cover strip, the open coil having a single structural yarn wound on itself to form a number of yarn turns. The number of yarn turns of being greater than or equal to two, the two ends of the single structural yarn being independent of each other, the yarn turns of the open coil making it possible to distribute the tensile forces exerted on the single yarn in wound form.

Systems and methods according to one or more embodiments are provided for a variable length self-locking lifeline system that prevents a user from falling off an elevated surface. In one example, a variable length self-locking lifeline system includes a processor and a lanyard. The lanyard is coupled between an anchor point and a user. One or more sensors determine, in real time, a current length and orientation of the lanyard as the lanyard responds to a user moving on an elevated surface. The processor is configured to trigger a locking mechanism to selectively lock the lanyard from further extension when a determined current length and current orientation exceeds a predefined safety perimeter of the elevated surface.

A fall protection and buffering device includes a retaining strip, a buffer strip, and a compensating arrangement. The buffer strip includes first and second textile layers overlappedly affixed with each other. The first and second textile layers are separated at one end of the buffer strip at the first strip section thereof and are affixed to top and bottom ends of the retaining strip respectively. The first and second textile layers are torn from each other sequentially along the buffer strip in response to a falling force applied to the retaining strip. The compensating arrangement has at least a binding section provided at the retaining strip to fasten the retaining strip in a folded state, such that the binding section compensates a tensile strength of the buffer strip for resisting a tearing between the first and second textile layers.

A device may include an anchor point operationally connected to a rebar, an E-clamp coupled to the anchor point, and a forcing handle configured to tighten the E-clamp to the rebar.

Provided is a safety hook fastening condition prediction system. More particularly, provided is a safety hook fastening condition prediction system that provides a central axis to a conventional safety hook zone, attaches a safety hook fastening case to the central axis, senses a safety hook fastening condition using sensor values of a pressure sensor, a movement sensor, and an altitude sensor in the safety hook fastening case, and predicts a risk.

Systems and methods for monitoring elevations of a set of workers at a job site include reference devices for capturing barometric pressures at different installation elevations on a structure and portable barometric pressure sensors carried by the workers. An atmospheric pressure offset may be calculated using the reference barometric pressures and installation elevations. The atmospheric pressure offset may be applied to atmospheric pressure measurements captured by the barometric pressure sensors carried by the workers to determine worker elevations. The worker elevations may be converted to corresponding floors of the structure.
