Claims7
A repair system for repairing a gearbox of a wind turbine uptower, the gearbox having a gearbox housing formed, at least, of a first portion and a second portion, the repair system comprising:
- a lifting apparatus for removably coupling to the first portion of the gearbox housing of the gearbox, the lifting apparatus adapted for lifting the first portion of the gearbox housing relative to the second portion of the gearbox housing;
- at least one gearbox housing support member adapted for mounting to the second portion of the gearbox housing so as to provide a support surface for the first portion of the gearbox housing, during a repair procedure of the gearbox, that is offset from the second portion;
- and
- a safety support coupled to a ring gear of the gearbox, the safety support being oriented so as to divert the first portion of the gearbox during an unplanned descent, wherein the safety support comprises a mounting bracket and a force arm, the mounting bracket defining a plurality of fastener openings for coupling to the ring gear, the force arm comprising a first end and a second end, the first end adapted for perpendicularly coupling to the mounting bracket, the second end adapted for positioning below the first portion of the gearbox housing.
