Work cages allow technicians to avoid climbing up and down the tower using the ladder (left). The cage takes them and their tools to the nacelle. Cages can be stopped in case there is work to be performed within the tower itself.
One training exercise (above) consists of a trainee playing the role of an unconscious worker. His colleagues fasten him to safety equipment and then lower the unconscious worker and themselves to the ground.
Cages can be stopped at any point in case there is work to be performed on the tower. When the doors open, the drive mechanism is disabled.
Many towers also include a ladder system with a pre-mounted fall protection system. The system should stop the technician after he or she falls a few inches. It remains locked until the technician can continue alone or can be helped by colleagues.
