LIFT SYSTEM FOR OPENING A TOP PORTION OF A NACELLE

A lift system for lifting an openable top portion of a nacelle of a wind turbine has first and second laterally spaced apart jacks pivotally connectable to a bottom portion of the nacelle and the top portion proximate a rear end of the nacelle. The first and second jacks are actuatable to raise and...

Zusammenfassung:	A lift system for lifting an openable top portion of a nacelle of a wind turbine has first and second laterally spaced apart jacks pivotally connectable to a bottom portion of the nacelle and the top portion proximate a rear end of the nacelle. The first and second jacks are actuatable to raise and lower a rear of the top portion. The lift system further has a support member pivotally connectable to the bottom portion and the top portion proximate a front end of the nacelle. A front of the top portion is pivotable on the support member when the first and second jacks are actuated without raising or lowering the top portion where the support member is pivotally connected. The lift system permits opening the top portion where the top portion has a U-shaped lip into which a complementary inverted U-shaped lip of a rotor fairing is inserted, and permits opening substantially rectangular or non-rectangular nacelles.
