Abstract
A wind turbine has a nacelle frame and a first hoist substantially permanently mounted on the frame. The method comprises the processes of hoisting a second, more powerful hoist and crane on the frame with the first hoist; removably mounting the second hoist and the crane on the nacelle frame; hoisting a winch using the second hoist and the crane on the frame, and removably mounting the winch on said frame; performing operations involving handling heavy parts employing said winch; and removing and lowering said winch, crane, and second hoist from the frame.
Claims18
A method of providing heavy lift capability to a wind turbine having a nacelle frame and a first hoist substantially permanently mounted on said nacelle frame for maintenance operations, said method comprising:
- utilizing said first hoist to lift a second hoist on said nacelle frame, said second hoist capable of lifting a heavier load than said first hoist;
- mounting said second hoist on said nacelle frame;
- mounting a crane proximate a rear portion of said nacelle frame;
- utilizing said second hoist and said crane to lift a winch to said nacelle frame;
- mounting said winch to said nacelle frame;
- and,
- performing lifting and lowering operations with at least said winch that involve handling heavy parts of said wind turbine.
A method for performing operations on a wind turbine that involve handling heavy parts, said wind turbine comprising a nacelle frame with a first hoist permanently mounted on said nacelle frame such that said first hoist is capable of moving in at least a lengthways direction along said nacelle frame, said method comprising:
- lifting a second hoist to said nacelle frame using said first hoist, said second hoist capable of lifting a heavier load than said first hoist;
- mounting said second hoist on said nacelle frame;
- hoisting a cable winch on the nacelle frame by said second hoist;
- mounting said winch on said nacelle frame such that said winch is capable of moving along said nacelle frame parallel to said first hoist;
- performing operations with said winch that involve handling said heavy parts of said wind turbine;
- removing and lowering said winch from said nacelle frame using said second hoist;
- and
- removing said second hoist from said nacelle frame and lowering said second hoist using said first hoist.
A system for performing operations on a wind turbine nacelle frame comprising:
- a first hoist substantially permanently mounted along an upper section member of said nacelle frame;
- and,
- a second hoist adapted to be positioned along a lower section member of said nacelle frame by said first hoist;
- wherein said first hoist can translate in at least one direction relative to said second hoist.
A nacelle frame assembly for a wind turbine comprising:
- a nacelle frame having an upper section member and a lower section member;
- a first hoist substantially permanently mounted along said upper section member, said first hoist capable of movement along said upper section member;
- a second hoist temporarily mounted along said lower section member of said nacelle frame;
- a crane temporarily positioned at a rear portion of said nacelle frame and coupled to said second hoist;
- and,
- a winch temporarily mounted along said upper section member of said nacelle frame;
- wherein said winch is used to move heavy wind turbine parts to and from said nacelle frame.
