Abstract: The invention relates to a system for limiting horizontal movements in a lift for humans or equipment in eg. a wind turbine tower or the like. The lift is to be provided with one or more sliding devices which, during the movement of the lift, guide(s) the lift by cooperating with a cable or the like. The system further includes a securing device for direct or indirect anchoring of the cable to the wind turbine tower. The sliding device and the securing device include tubular units that are adapted to each other to the effect that the tubular unit of the securing device is able to slide within the tubular unit of the sliding device.

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.
