LT5002-1 Blade Eagle

The Blade Eagle is one of our advanced remote-controlled blade yokes for offshore installation. Ideal for electric-pitch turbines, the Blade Eagle installs each blade between +/- 30° from horizontal. No turning gear is required, as the yoke itself is used to turn the rotor. Only the yaw motor is used. A built-in sensor informs the operator when the crane hook is directly above the yoke, which ensures safe release of each blade with no swerving of the yoke.


  • Enables installation of all three blades without using turning gear
  • Gust winds up to 18 m/s
  • Duplicate electrical components (two independent systems)
  • Duplicate hydraulic pumps and directional valves
  • Camera system eases grabbing and ungrabbing sequence
  • Interactive user manual on tablet
  • Prepared for Liftra Tagline System
  • Blade pressure equalization system, minimizing loads onto blade
  • DNV approved

Installation procedure
The first blade is installed and is then lowered to a -60° angle supported by the yoke. This positions the next blade bearing horizontally opposite, ready to receive blade number two.
The turbine is then yawed 180°, and the second blade is installed in horizontal position. The blade is raised to a 30° angle to position the final blade bearing. The turbine is yawed back 180°, after which the third blade is installed.
