Machining Solutions For On- & Offshore Wind Turbines

Uptower machining solutions for yaw teeth segments, rotor locks, bolts and threads. Repair instead of replacing the component, minimizing downtime and eliminating heavy logistics.

Uptower Solutions

Keep Turbines Running. Minimize Downtime. Avoid Costly Replacements.

When a critical component fails uptower, the traditional answer is component exchange: heavy lifting equipment, extensive logistics and prolonged downtime. We bring precision machining into the turbine instead - the damaged component is repaired where it sits, with no unnecessary disassembly.

Portable, high-precision equipment restores damaged yaw ring teeth, worn rotor locks, broken bolts, damaged threads, generator shafts and housings directly in the nacelle - restoring functionality and extending component lifetime.

  • No crane mobilization, no nacelle disassembly, no transport logistics or workshop dependencies
  • Back in operation in 3-7 days, versus 3-4 weeks for crane-based options
  • Around 80% lower total cost than component replacement, at OEM-certified tolerances
