A weight bearing fall protection connector includes a first connection member configured to attach the connector to a piece of fall protection equipment, and a second connection member configured to attach the connector to another piece of all equipment, with the connection members fixed to each other to transfer the weight of a worker in a fall event and for movement relative to each other between a ready position and a fall position. The connector further includes a breakable component having a retaining condition wherein the component maintains the members in a ready position and broken condition wherein the component allows the members to move to their fall position. The connector further includes a wireless fall indicator including a wireless transmitter and a switch configured to activate the wireless transmitter in response to movement of the members from the ready position to the fall position.

A buckle structure includes a hook-shaped buckle body and a movable bolt. The hook-shaped buckle body includes a question mark-shaped body and a blocking section provided at an upper end thereof, a receiving cavity is formed between the movable bolt and the question mark-shaped body. The lower end of the movable bolt is hinged at the lower end of the question mark-shaped body, the upper end of the movable bolt is elastically contacted with the upper end of the question mark-shaped body. the contact point of the movable bolt and the hook-shaped buckle body is located in the middle of the hook-shaped buckle body, so that the buckle can be easily mounted on the buckle structure as long as the buckle is sleeved on the blocking section and the buckle is moved in the direction of the receiving cavity.

A self-locking device for hanging objects on a mounting surface is disclosed. The self-locking device includes a mounting bracket and a locking arm member engaged with a track portion of the mounting bracket. The track portion comprising a pair of guide portions, a pair of lip portions extending from a lower end of the guide portions, a pair of rotation portions extending from an upper end of the guide portions, and a slot extending between the pairs of guide portions, lip portions and rotation portions. The arm member being mated with the track portion such that the arm member is translatable along the track portion. The arm member comprising a tip portion, a base portion positioned at least partially within the slot, and at least two pairs of projections extending from the base portion that engage with one of the pairs of guide portions, lip portions and rotation portions.

A lockable safety hook such as used for lifting loads and the like wherein the locking mechanism features a double locking function by way of a lock securing device arranged to prevent movement or unintentional activation of the locking mechanism by locking the lock.

Devices formed from interconnected components. Each assembled device comprises a yoke component, a boss component and an axle bolt. The yoke component comprising: a. carabiner body that includes a back, an opening, and a yoke formation. The yoke formation is constituted by a U-shaped section that is open to the outside of the body, and which defines a space between two legs, the legs having bearing surfaces through each of which a respective axle bore is formed. The back extends from the yoke formation to an end at a first limit of the opening. A spur extends from the yoke formation to an end at a second limit of the opening. A gate on the body can pivot between a closed position, in which it closes the opening, and an open position in which an object can be passed through the opening into a space within the body. The boss component has flat, parallel external bearing surfaces, an axle bore extending through the boss component, the axle bore opening at each bearing surface. The axle bolt passes through the axle bores in the yoke and boss component.

A tandem pulley includes a support bracket having the shape of an inverted U. The support bracket defines a through hole. A pair of sheaves is arranged in line inside the support bracket. Each sheave is mounted rotating freely around a spindle fixed to the support bracket. A carabiner is fitted in the through hole. A connector is configured to connect the support bracket with the carabiner. The connector is configured in such a way as to allow rotation of the carabiner around an axis parallel to the spindles of the pair of sheaves. A spring is connected to the support bracket, the spring being arranged to exert a force on the carabiner biasing the latter to a rest position by rotation of the carabiner.

Techniques are described for monitoring and controlling fall protection equipment. For example, the techniques of this disclosure may be used to monitor the connection status of fall protection equipment, e.g., whether or not the fall protection equipment is connected to a support structure. The techniques described in the disclosure may determine whether the fall protection equipment is connected to a support structure based on changes in a resonant frequency of an electronic circuit of an inductive sensor within the fall protection equipment. The inductive sensor may be formed from sets of one or more coils, where a first set of one or more coils and a second set of one or more coils are wound in opposite directions.

A weight bearing fall protection connector includes a first connection member configured to attach the connector to a piece of fall protection equipment, and a second connection member configured to attach the connector to another piece of all equipment, with the connection members fixed to each other to transfer the weight of a worker in a fall event and for movement relative to each other between a ready position and a fall position. The connector further includes a breakable component having a retaining condition wherein the component maintains the members in a ready position and broken condition wherein the component allows the members to move to their fall position. The connector further includes a wireless fall indicator including a wireless transmitter and a switch configured to activate the wireless transmitter in response to movement of the members from the ready position to the fall position.

A quick-connect connection system assembly for attaching attachments or tools to industrial and construction equipment for purposes of moving and placing materials and items, particularly heavy items, at varying heights relative to the ground. The connection system can have a mounting mechanism that generally comprises a rotatable latch that can be selectively retained in at least one of an open position and a closed position, including through the use of a magnet coupled with the mounting mechanism. The rotatable latch can be selectively rotated between the open and closed positioned via interaction with a cross member of the industrial equipment and the effect of forces acting upon the rotatable latch member, and with limited interaction by an operator of the industrial equipment.

A carabiner includes a (a) a hook, (b) a gate including a cantilever spring and (c) a first pivot connecting the gate to the hook. A second pivot also connects the distal or free end of the cantilever spring to the hook.
