Abstract

A fall arrest device for blocking a rope when a relative speed between the rope and the device reaches a threshold value comprises a blocking mechanism for blocking the rope, and a trigger mechanism configured for triggering an activation lever of the blocking mechanism for activating the blocking mechanism for blocking the rope when the speed reaches the threshold value, wherein the trigger mechanism comprises a drive axis rotated by the rope upon relative movement between the rope and the fall arrest device, the drive axis carrying a centrifugal weight holder, wherein at least one centrifugal weight is held acting against a restoring force of a spring, wherein the at least one centrifugal weight is movable between an inactive position and a trigger position for triggering the activation lever when the speed reaches the threshold value. The centrifugal weight holder is arranged rotatably relative to a release gear that comprises a toothing engagable by an actuator member of the at least one centrifugal weight, when the at least one centrifugal weight is in the trigger position.

Abstract

The invention relates to a slider for a climbing protection system as fall protection for persons on ladders having a C-profiled guide rail. The slider comprises a slider body (14), a detent pawl (11), and a first and second roller pair (15, 21) for guiding the slider (10) in the guide rail. The first roller pair (15) can be twisted relative to the slider body (14). In order to be able to attach the slider in any position to the guide rail and to ease operating both by left-handed and right- handed persons, the second roller pair (21) is mounted on a slider carriage (30) connected to the slider body (14) tiltably about a tilt axis running parallel to the rotation axis of the second roller pair (21), and/or in that the rollers (21A) of the second roller pair (21) are arranged on a shaft (27) mounted floatingly on the slider (10).
