An automatic rappel fall prevention device is a piece of personal protection equipment; it should be allocated to a single user (it can only be used by one person at a time). When the user moves (up or down), the cable winds onto and unwinds from a pulley. The cable is kept taut by means of a return spring. In the event of a fall, a system locks the cable and prevents it unwinding, thus stopping the fall instantly.

User safety relies on the effectiveness of the equipment and full understanding of the safety instructions contained in this leaflet. Product markings should be checked periodically for legibility.

L’émerrillon haut is linked to an anchor point by a connector (EN362) and the other end (cable or strap) is attached onto a safety point on a harness. Sharp edges, small diameter structures and corrosion should be avoided as they may affect the performance of the cable or strap; or they should be adequately protected.
