Embodiment Construction

[0018] The system comprises a fall protection device (1) and a climbing aid (10).

[0019] In the depicted description, both the fall protection device (1) and the climbing aid device (10) are fastened to a safety belt (4) used eg by workers performing maintenance on a wind turbine.

[0020] The fall arrest protection device (1) is fastened to the safety belt (4) by means of a snap hook (2), which is connected to a hinge (5) on the fall arrest protection device. In the illustrated embodiment, the fall arrester is coupled to a wire (3) that acts as a guide, and the fall arrester and wire are constructed and co-operate so that when the hinge is subjected to one direction (in the illustrated exemplary The fall arrester is able to slide on the wire when affected by a force in an upward direction in an embodiment, and locks securely on the wire when the hinge is affected by a force in the other direction.

[0021] The safety belt (4) is also fastened to another line (14) by anothe...

Abstract

The invention relates to a system for protecting individuals during work on ladders with steps. The system comprises an anti-fall protection device and a ladder climbing assistance device. The anti-fall protection device and ladder climbing assistance device are attachable to an individual by means of lines, safety harness or the like. The anti-fall protection device comprises a hinge for being secured on a guide means and anti-fall protection device and guide means are adapted to each other so that the anti-fall protection device is able to slide on the guide means when the hinge is influenced by a force in one direction and is securely locked on the guide means when the hinge is influenced by a force in another direction. The system comprises a breaking piece for insertion between worker and climbing assistance, which breaking piece and climbing assistance are adapted such to each other that the breaking piece is able to resist the force that occurs in normal use of the climbing assistance, but is broken in case of the increased force exercised on the climbing assistance by an individual when falling.

Description

technical field [0001] The invention relates to a system for protecting persons during work on a ladder with rungs, the system comprising a fall protection device and a ladder climbing aid, said fall protection device and a ladder climbing aid The device can be attached to the person by a cord, harness or similar. The fall arrester includes a hinge for fastening to the guide, the fall arrester and guide cooperating so that when the hinge is subjected to a force in one direction, the fall arrester is able to rest on the guide slides upward, while the fall arrester locks securely to the guide when the hinge is subjected to a force in the other direction. Background technique [0002] When it is necessary to perform work at very high places, such as when performing wind turbine maintenance, workers are often required to stand on internal or external ladder structures for extended periods of time. On the one hand, people performing such tasks usually have to climb long distanc...
