Rotor blade inspections on wind turbines

We inspect the rotor blades of your wind turbine right from production up to smooth operation!

Rotor blades must withstand enormous loads during the operation of a wind turbine.
They are permanently exposed to an extremely dynamic load spectrum and are directly exposed to constant environmental influences such as temperature changes, rain, UV light and lightning.

Due to their shape and size, rotor blades are costly to produce and maintain. If damage to rotor blades is discovered too late, it will result in high repair costs and long downtimes. Continuous monitoring of the rotor blades – during manufacturing and operation – prevents this. With regular inspections for condition-based maintenance, initial damages can be detected within reasonable time and can usually be repaired with little effort. Repairs can thus be planned and carried out under favourable conditions. This also reduces costly downtimes! Continuous monitoring ensures trouble-free operation and reduces maintenance costs.

We "go the distance" and climb high for you with our innovative rope access technology for rotor blades! This allows quick and flexible responses to individual needs:

  • Suitable for any turbine type, size and hub height
  • Applicable everywhere – for onshore and offshore turbines
  • Optimum access to all outer areas of the rotor blade
  • Low technical effort
  • Short downtimes
