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.
