Harnesses for supporting a person working at height are disclosed. They include a back, leg loops, two forward connection arrangements and a flexible load-bearing member that extends between the connection arrangements, the forward connection arrangements serving to transferring load from the back and the leg loops to the load-bearing member. Each forward connection arrangement includes: a base that is permanently connected to the harness and retention components that can be removably and rigidly connected to the base to removably secure the flexible load-bearing member to the body.

A rope locking apparatus includes a main shaft and a friction wheel pair having friction surfaces used for clamping a rope. A centrifugal member is switches between a centrifugal state and a reset state as the rotation speed of the friction wheel pair changes The centrifugal member drives the main shaft to rotate when it is in the centrifugal state, and is separated from the main shaft when it is in the reset state. The two friction wheels are respectively installed at two ends of the main shaft. A lock located between the two friction surfaces and arranged on the main shaft is adapted to rotate along with the main shaft, to make the lock switch between a locked state and an unlocked state. In the centrifugal state, the main shaft drives the lock to the locked state; and in the reset state, the lock is in the unlocked state.

A rope anchor with a J-shaped a body having a hook and spine. The end of the spine has an attachment hole for a rope and an elongated, teardrop-shaped rope slot that is either enclosed or gated. The gate is biased closed to span the open side of the rope slot and pushed opened to allow access for a rope. A tip, composed of a flat chip of metallic material, fits into a slot at the end of the hook. The tip is generally triangular with two or three sharp corners, or square or rectangular with four sharp corners. The slot orients the tip so that only one of the sharp corners is exposed, or so that two adjacent sharp corners are exposed. When an exposed sharp corner is not suitable for use, the tip can be reoriented to expose a different sharp corner.

Described herein is an assembly and methods of use thereof for controlling or governing the relative speed of motion between the assembly parts via eddy current formation. The assembly and methods also may minimize the number of parts required and may minimize the number of moving parts thereby increasing the mechanical durability of the assembly compared to art designs that may have more moving parts and greater part complexity.

A fall arrest connector is used to connect at least a safety belt with a snap hook and a wearable harness for a user to wear. The fall arrest connector includes a retaining ring, a buckle ring, and a breakable connection. The retaining ring, including the first connecting portion, is connected to the wearable harness. The buckle ring, including the second connecting portion, is hooked by the snap hook. The breakable connection connects the second connecting portion and the first connecting portion. When the retaining ring or the buckle ring is pulled by a predetermined external force, the breakable connection is broken to separate the first and the second connecting portion. The retaining ring and the buckle ring could respectively be connected to the substitute protection device, which could provide the user an instant protection when the first connecting portion and the second connecting portion are separated.

A fall arrest device includes a braking device, a frame, and a rotating member connected to the frame. The rotating member includes a main body and a plurality of pawls which are pivotally connected to a mounting portion of the main body. Each of the pawls has an abutting portion, a pivot, and a body portion. The braking device has a plurality of abutted portions. When a rotation speed of the rotating member is greater than or equal to a predetermined rotation speed, the abutting portions abut against the abutted portions to stop a rotation of the rotating member. When the rotation speed of the rotating member is smaller than the predetermined rotation speed, the body portion of each of the pawls touches a periphery of the abutted portions and swings as an outer diameter of the abutted portions of the braking device changes.

A fall protection system includes an elevation mechanism including a base end and an elevated end, and that is configured to permit a user to scale the elevation mechanism. The first channel is disposed at a first side of the elevation mechanism and extends between the base end and the elevated end, and is configured to anchor a first shuttle to the elevation mechanism and permit the first shuttle to transition between the base end and the elevated end of the elevation mechanism. The second channel is disposed at a second side of the elevation mechanism and extends between the base end and the elevated end, and is configured to anchor a second shuttle to the elevation mechanism and permit the second shuttle to transition between the base end and the elevated end of the elevation mechanism.

A connection arrangement for use with a wearable body harness includes a first connector having a first body component, a second body component, and an attachment element connected to each other by a rod having a longitudinal axis. The connection arrangement further includes a second connector removably connectable to the first connector. Each of the first body component, the second body component, and the attachment element are independently movable relative to each other about the longitudinal axis of the rod. The first connector and the second connector are removably connectable to each other via a locking and release mechanism between a first, locked configuration, where the first connector and the second connector are connected to each other, and a second, unlocked configuration, where the first connector and the second connector are disconnected from each other.

A weight-activated anchoring and alerting apparatus which serves as both (a) an anchoring device or anchoring extension for a fall arrest or other fall protection system and (b) an automatic alarm system which notifies rescue personnel or others when the worker, hunter, or other person wearing the fall protection system has fallen and is in need of rescue.

A wireline traversal device may include an outer housing having a longitudinal slot, and an inner housing rotatably disposed within the outer housing. The inner housing includes a helical slot, a forward end of which is aligned with the longitudinal slot in the outer housing when the inner housing is in a home position. A forward end cap having a longitudinal slot and an inclined engagement surface is attached to a forward end of the outer housing. The longitudinal slot on the outer housing is aligned with the longitudinal slot on the forward end cap. At least two bearing members are rotatably disposed within the outer housing, with one bearing member attached to each end of the inner housing. The wireline traversal device may be used in a variety of applications in connection with a wireline, such as a zip line or safety line.
