LT998-1 Gearbox Rigging

Siemens 2.3 MW

The lifting system has been developed to lift the Winergy gearbox of the Siemens 2.3 MW wind turbine. The lifting system has two chain hoists, which allows adjusting the gearbox to the correct position for removing and installing it on the main shaft in the nacelle.

At every fourth attachment point on the gear box, a load cell ensures correct load distribution when gearbox is lifted. Additionally, the lifting system has two attachment points, which keep the gearbox in position when it is slid clear of the main shaft, and when the replacement gearbox is pulled onto the main shaft.
