Method and system for wind turbine component replacement

摘要

The method may include coupling a spreader [150] to a wind turbine component, raising a hoist [102] into the nacelle [12], raising a spool of cable into a nacelle of the wind turbine, mounting the hoist on a member of the nacelle, routing the cable [192] from the spool of cable to the hoist, and routing the cable between at least one sheave disposed on the hoist and at least one sheave disposed on the spreader. The system [100] may include a spreader [150], the spreader adapted to couple to a wind turbine component, the spreader including at least one longitudinal member, a pair of transverse members, and at least one first sheave, and a hoist [102], the hoist adapted to couple to a member [14; 16] of the nacelle [12], the hoist including a frame, a motor, and at least one second sheave.
