Avanti Wind System has developed a safe and easy Fall Protection System with a safety rail installed as part of the ladder. Avanti Fall Protection can be used by several technicians at the same time contrary to most other systems based on wires. Throughout the length of the ladder a technician can connect himself to Avanti’s system for every 6 meters. The technician carries a special click-on runner in his safety harness. The click-on runner is fastened to his harness with a snap hook like the ones used by mountain climbers. When entering the ladder – anywhere in the tower – the technician clicks the runner onto the safety rail in the center of the ladder. The click-on runner follows the user up and down. If he loses his foothold, the runner will immediately lock, and he will be hanging in the safety system until he gets a foothold again or until his colleagues can help him.
