Beyond 6.50 metres between the tower and the blade of the wind turbine, a wire-rope guidance system keeps the blade away from the tower.

2 wire-ropes are stretched from the collar of blades to the ground, parallel to the blade to be cleaned, in order to allow the platform to slide on an inclined plane.

The tension of wire-ropes is ensured by 2 traction winches with cable passage: HIT 16.
