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.

A cable sleeve comprises a housing, a locking cam, and a locking pawl. The housing has an elongate member passage configured to slidably receive an elongate member and has a cavity. The locking cam and the locking pawl are pivotally connected to the housing within the cavity. The locking cam has a radial edge with a constant radius relative to a pivot connection between the locking cam and the housing and is configured to move from a first cam position to a second cam position configured to engage the elongate member in the elongate member passage with the radial edge. The locking pawl is configured to move from a first pawl position to a second pawl position configured to move the locking cam into the second cam position to engage the elongate member.

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 runner 7 has a housing 21 with two runner wheels 23 attached to the housing. The housing includes a sleeve 25 that can freely turn around the longitudinal axis 27 in a channel 29 present in the housing. The sleeve constitutes an elongated guide opening by which the runner can be moved over the guide cable. Longitudinal slots extending in axial direction are present in the walls 21A, 25A of the channel 29 and of the sleeve 25. Each slot has a middle section 31A, 33A. The width 34 of the middle section 33A of the longitudinal slot in the sleeve is smaller than the width 32 of the middle section 31A of the longitudinal slot in the housing, and, furthermore, the width 34 of the middle section 33A of the slot 33 in the sleeve is smaller than the diameter of the guide cable 3 the runner 7 is suitable for.

The connection device (1) comprises a coupling connector (5) in the form of an open ring (5a) with a closure finger (5b), which is rendered permanently integral, by means of an articulated connection or by means of a rigid connection, with a connection apparatus (4) which can ensure the selective connection to a rope (3). The manipulation of the connection device is thus facilitated, and the risks of incorrect relative positioning of the coupling connector (5) and the connection apparatus (4) are avoided.

A fall control system is described. The fall control system comprises an elongate guide rail extending along an axis, a trolley for moving along the elongate guide rail, a tether attached to the trolley at a first end, a second end of the tether for attaching to a user, and a speed control system for controlling a speed of the trolley along the elongate guide rail. The speed control system comprises one or more than one speed control track attached to the elongate guide rail and extending along the axis, a background speed controller coupled to the trolley and engaged with the one or more speed control track when the speed control system or the trolley is in a travelling orientation and controlling the speed of the trolley along the elongate guide rail to not exceeded a maximum walking speed. The speed control system also includes a speed controller coupled to the trolley and engagable with the one or more than one speed control track, the speed controller displaceable from a first position when the speed control system or the trolley is in the travelling orientation, and the speed controller is not engaged with the speed control track, to a second position when the speed control system or the trolley is in a falling orientation and the speed controller is engaged with the speed control track. The speed controller for controlling the speed of the trolley along the guide rail in the falling orientation to not exceed a maximum fall speed.

A trolley for use with a fall arrest system, the trolley providing active control of both downward movement of a body attached to a rope or cable and horizontal position along a track.

An anti-torque safety hook includes a main body, a gate member, and a detent member. The main body has a hook opening passing through the front and back sides thereof, a passage communicating to the right side of the hook opening, a female buckle arranged on the passage, a connection unit arranged below the hook opening, and an energy absorption area arranged on the left side of the hook opening. The gate member has a first end mounted on the main body and a second end comprising a male buckle, adapted for detachably coupled with the female buckle, so as to allow the gate member to open and close the passage. The detent member is coupled on the main body and maintained at a first position, so as for ensuring that the gate member closes the passage, while when the detent member is operated and switched to a second position, the safety is disarmed. The present invention mainly utilizes the detent member to ensure the gate member to close the passage. When the main body bears the designated torque, the energy absorption area allows the main body to distort in response while the gate member may still close the passage, so as to prevent the risk of decoupling and in order to meet the standard of ANSI/ASSP Z359.12-2019.
