A ratcheting strap adjuster comprising a bracket, a webbing plate, and one or more captive members. The webbing plate is rotatably coupled to the bracket. Each of the one or more captive members is moveable between an engaged position and a disengaged position, wherein the one or more captive members restrict rotation of the webbing plate in one direction when the one or more captive members are in the engaged position and allow rotation of the webbing plate in the one direction and in an opposite second direction when the one or more captive members are in the disengaged position.

A fall arresting/prevention safety protection device for aerial lifts that delivers notifications and warnings to individuals who are subject to accidental falls or other safety hazards when performing construction or the like or when operating elevating construction machinery such as aerial lift work platforms, bucket trucks and similar type elevating work platforms. The invention further provides a load sensor that when activated transmits an emergency signal to operators, supervisors and emergency personnel. The present invention further provides a remote control to access and control movement of the aerial lift through a wireless transmission in the event the lift operator falls out of or is ejected from the bucket or work platform.

A preferred embodiment suspension trauma relief strap assembly for use with a full body harness includes a pair of straps connectable in two configurations. The first configuration is formed by engaging a hook of one strap with one of a plurality of closed loop arrangements of the other strap to form a sling upon which a person donning the full body harness may stand. The second configuration is formed by engaging the hook of the one strap with one of the plurality of closed loop arrangements of the one strap and engaging the hook of the other strap with one of the plurality of closed loop arrangements of the other strap to form two slings upon which a person donning the full body harness may stand.

A safety apparatus for personnel on an oil drilling rig includes a cylindrical quick disconnect switch having a receptacle and a plunger. The receptacle has an open circuit pair of electrical wires. The plunger is configured to attach to a derrick man. The plunger and the receptacle are configured to mate when the plunger is inserted into the receptacle and to remain frictionally mated until pulled apart. The mating results in closing the circuit between the pair of electrical wires.

A method for detecting a fall of a worker attached to an anchor device includes steps for: a) measuring an orientation of a worker, using an orientation sensor with six axes on board a fall detection apparatus secured to the worker; b) calculating statistical properties representative of the measured orientation; and c) comparing statistical properties of reference values, a fall being considered to be detected only if the statistical properties correspond to the reference values according to predefined criteria, the comparison being done using an automatic classifier.

An adjustable lineman safety belt having a body secured to a user with a belt tongue. A primary strap and auxiliary strap, each separately and independently adjustable, extend along the body spaced apart from one another and secured at each terminal end to a different D ring. The belt tongue shares D rings with the primary strap. Each strap includes an adjustment member permitting selective adjustment of the strap length, such as by sliding. Strap length adjustment similarly varies the distance between corresponding D rings, maintaining the weight distribution and balance of the overall device. Safety straps connect the auxiliary strap to the body while also permitting adjustment of the length. Drop straps connect the belt tongue to the body and safety strap for added safety in case of a fall. Covers also protect each of the adjustable members to prevent from accidental adjustment while the belt in is use.

A combination leg pad and trauma strap comprises a trauma strap and a leg pad. The trauma strap includes an intermediate portion interconnecting a proximal end and a distal end. The proximal end includes a loop forming a first portion and a second portion. The leg pad includes a pad, a pad cover, and a housing panel. The first portion is positioned proximate the housing panel and the second portion is positioned between the pad cover and the pad. The pad cover and the housing panel form a channel through the loop between the first and second portions configured and arranged to receive a leg strap of a safety harness thereby connecting the trauma strap to the safety harness when installed on the safety harness.

The portable fall protection device essentially comprises a force reduction device that gradually absorbs a tensile force created within a safety line as a user falls from a height. One aim of the portable fall protection device is to gradually arrest the descent of the user falling in a gradual controlled manner to prevent injury to the user. Furthermore, the portable fall protection device is compact such that it can be constantly worn and carried on the back of the user without impinging on the tasks of the user. As a result of the structure of the portable fall protection device, each portable fall protection device can be individually tested prior to use and can be re-used (and/or reset), if necessary after a fall. In addition, the capacity of the portable fall protection device is adjustable and can be set by a manufacturer and/or operator to produce a bespoke device.

Embodiments relate generally to systems and methods for quickly detecting a fall and alerting appropriate parties of the fall. A fall protection device may comprise a fall detection module operable to sense when a fall occurs and generate wireless beacon, where the beacon may be received (or picked up) by any number of wireless devices, including wireless gateways, monitoring stations, and mobile devices.

A wearable harness has a first strap overlapping a second strap, with each of the first strap and the second strap having a longitudinal axis extending in a direction of a major longitudinal length. The wearable harness further has a reinforced opening extending through each of the first strap and the second strap. The reinforced openings have a pivot axis extending in a direction substantially perpendicular to the longitudinal axis of each of the first strap and the second strap when the reinforced openings overlap each other. The first strap and the second strap are pivotally movable relative to one another about the pivot axis of the central openings.
