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.

Abstract: The invention relates to a lift cage, in particular a lift cage for persons, for navigating towers, cranes, wind energy plants, pillars of wind energy plants or the like, with a floor 4, with a plurality of side walls 11 rigidly connected thereto and with a lateral opening 12 which can be closed by means of a door 20 between two opposing side walls 11, the door 20 having two door wings 21 which are displaceable parallel to each other. In order to allow secure locking of the door and convenient entry, according to the invention one door wing 21 is displaceably supported by the other door wing by means of a plurality of longitudinal pullouts and guided by means of first guide means in guides 15 parallel to the lateral opening 12 and by means of second guide means in guides 16 parallel to one of the side walls 11.
