There is provided a slider device that includes: a slider main body that can move in the extending direction of a handrail while holding the handrail; and a plurality of pairs of rollers that are provided on the slider main body in a plurality of places apart from each other in the extending direction of the handrail, grasp side surfaces of the handrail, and can travel on the side surfaces of the handrail. One of the rollers facing each other across the handrail is a fixed roller fixed to the slider main body and the other of the rollers facing each other across the handrail is a movable roller supported in such a manner as to be able to get farther or closer with respect to the handrail, and each movable roller is biased toward the handrail by a biasing member.

A cable holder and a running element for a cable system of an anti-fall device, wherein the cable holder is reversibly rotatably mounted and the axis of rotation of the cable holder is offset parallel to a cable.

A connector apparatus includes a first connector and a second connector. A housing defines a first channel and a second channel and a locking mechanism configured to secure one of the first and second connectors within the first channel or the second channel. The locking mechanism includes a disk with a rotational stop, and a latch arm pivotable between at least a latched position and an unlatched position. When the first connector is secured within the first channel by the disk and the second connector is inserted into the second channel, the second connector actuates the latch arm towards the unlatched position such that the disk is enabled to pivot and secure the second connector to the housing while simultaneously releasing the first connector from the housing.

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.

A safety restraint system for a person comprising two carabiners configured to receive at least one restraint element, each of the carabiners comprising a hook for receiving the element, a gate comprising a first branch forming a door and a second branch for actuating the door, a first means for locking the gate in a holding configuration. The system further comprising a transmission device connecting the carabiners together, the device arranged to make it impossible to switch from a state in which each of the carabiners is secured to an element to a state in which neither of the carabiners are secured to an element.

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.

A safety line anchor device with a first component, the first component having a connection part at first end and a gripping element at a second end, a second component, the second component having a first opposed end portion, a second end portion, and a pin fixed in position and protruding from the second component, and the first component is slidably mounted to the second component and the gripping element separates the first opposed end portion and the second end portion.

There is provided a climbing locking system for climbing ladders in particular of a wind power installation. The climbing locking system has at least one climbing ladder segment having a longitudinal direction and at least one open end for accommodating a fall arrester which can move back and forth as a climbing protection system along the longitudinal direction. The climbing locking system also has at least one climbing locking unit at the at least one open end of the climbing ladder segment. The climbing locking unit is fastened pivotably to the climbing ladder segment and has a locking position for locking a movement of a fall arrester along a direction of the climbing ladder segment and a passing position for allowing a movement of the fall arrester along the longitudinal direction of the climbing ladder segment in both directions.

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.

A safety line traveller (1) for a fall protection system has a first component (2) in sliding engagement with a safety line (40), and a second component (3) which hinders sliding contact of the traveller with the safety line (40). The first and second components (2,3) are normally held in a sliding configuration in which the second component (3) is spaced from the safety line (40) and the first component (2) provides sliding contact with the safety line. The first and second components (2,3) are reconfigurable to an alternative configuration in which the second component (3) engages with the safety line (40) in order to hinder sliding of the traveller (1) on the safety line (40).
