Major Component Exchange
Removal and replacement of gearboxes, generators, main shafts and blade bearings, executed with engineered lift plans, precise rigging and minimal downtime.
Protect asset life and production targets.
Major Component Exchange is a critical service for maintaining the long-term performance and safety of wind turbines. Using advanced rigging techniques, engineered lift plans, and crane coordination, we execute exchanges with precision and minimal downtime.
Whether it’s a planned replacement or an emergency swap due to catastrophic failure, Aegis Onshore ensures each MCE is performed safely, efficiently, and in full compliance with OEM standards.
- Gearboxes & generators, uptower or with crane support
- Main shafts & blade bearings
- Engineered lift plans with pre-lift inspections and NCCCO operators
- OEM platforms including GE, Siemens Gamesa and Nordex/Acciona
Heavy lift, coordinated end to end.
From nacelle swaps and blade replacements to structural lifts, we coordinate engineered lift plans, rigging, transport logistics and on-site operations, with crawler, all-terrain and hydraulic truck cranes.

Aegis field photoMCE questions
Which components does an MCE cover?
High-value turbine components such as gearboxes, generators, main shafts, and blade bearings.
Can some exchanges be done without a crane?
Yes. Many corrective repairs, especially for gearboxes, bearings, and generators, can be completed uptower without cranes, reducing cost and downtime.
Do you handle the crane and lift planning?
Yes. We coordinate engineered lift plans, rigging, crane transport, setup and permitting, with NCCCO-certified operators.
Do you respond to emergency failures?
Yes. Whether it’s a planned replacement or an emergency swap due to catastrophic failure, we mobilize crews and lift planning fast.
Component down? Let's plan the swap.
Planned maintenance, a failed component or storm damage: tell us the site and the problem and the right crew responds.
