Performing a work on top of a ladder constitutes an important factor of risk. The Sekurcable Sekuralt system aims to secure the users when ascending up the ladder. The cable is placed over the length of the ladder then can be used as an anchorage support with a mobile fall arrest device anchoraged to the front or lateral anchorage point of the harness. The fall arrester circulates over the cable, while the user is ascending or discending and automatically locks in case of a fall.
