  • Publication number: 20140124296
    Abstract: A combination of a drive mechanism associated with a fall arrest device. The drive mechanism includes a drive motor, a rope drive wheel, and a freewheel having a sleeve with axial recesses and clamping faces on an inner surface, which the clamping bodies are guided in a cage and are located in the recesses. The fall arrest device includes a drum onto which a safety rope is wound, a return spring configured to be tensioned during the unwinding of the safety rope from the drum, and a locking device configured to lock the drum against rotation in the safety rope in an unwinding direction in the event of a fall of a person carried by the safety rope.

  • Patent number: 8579086
    Abstract: The invention relates to a crash safety device having a safety rope (105) wound onto a drum, a recuperating spring tensioned by the drum during the winding of the rope, and a locking device for blocking the drum from rotation in the rope unwinding direction during the crash of a person secured by the rope. A rope drive mechanism is provided in order to unwind the rope (105) from the drum and to slowly move the rope end having a hook (290) attached thereto toward such that a person can hook onto the safety rope (105). The drive mechanism has a motor (140) driving a rope drive wheel (210) via a freewheel (200) for lowering the rope end having the hook (290). In order to rewind the rope, the motor (140) is operated in a reverse direction of rotation at a controlled rotational speed in order to limit the speed at which the rope (105) is pulled up by the tensioned recuperating spring.
