The first mobile rotor blade workshop

Wind turbine class from V90 to V136
expandable up to V150
Max. distance between blade tips 15.2 m
Max. wind speed 14 m/s
Rotor blade dimensions from 4.3 m x 2.2 m

Flexible rotor blade access with a spacious work place

The integrated cabin of our access system is mounted with a flexible joint so that it can rotate to follow the twist of the rotor blade. As a result, the gaps between the blade and the roof/floor of the cabin can be minimised at every point along the rotor blade. This enables optimised 360° access to the rotor blade and provides effective protection against the elements.

  • Simple sealing against the effects of weather
  • Maintenance cabin rotates to follow the twist of the rotor blade
  • Optimised rotor blade access
  • Spacious work place with workshop-like conditions for working

Keeping you safe while you work

No system overloading. No tipping. For turbines of all sizes.

Dependable. No job too big.

The triple winch system and the integrated crosswind detection function keep the System terra 1.1 safe even in high winds and on large wind turbines and prevent the cabin from tilting over sideways. Anchoring points for attaching an overhead safety harness mean increased safety for your service engineers.

  • Adaptive 3-winch system
  • Crosswind detection function automatically initiates safety procedures
  • Frame swivels to position the chamber around the blade tip at the push of a button
  • Automatic slope correction function keeps the chamber level at all times
  • Operator anchoring points available on the cabin ceiling
  • Integrated uninterruptible power supply (battery) ensures the safe return of the chamber to ground level even if a power outage occurs
  • Frame rolls safely over joints between segments of hybrid towers
  • Lighting for the working area and for the entire upward/downward travel zone
  • Tailored lighting concept
