Blade lifting tools and rotary hub tools for wind turbines

For her client Lagerwey, a Dutch manufacturer of wind turbines, MechDes designed a tool for lifting the generator and rotating the hub to the correct position. We also designed a lifting tool for placing the 66.5 meter long blades.

For the first tool, we designed two pinion drives to drive the wind turbine in the correct direction. The gear is made up of several thin plates of high-strength steel, which are clamped together. The shape of these plates differs slightly from each other, so that the force is well distributed.

For the other tools, we designed two lifting tools for assembling and disassembling the 66.5 meter long blades. These tools are clamped around the wick for sufficient grip. It is important to limit the pressure on the wick so that it is not damaged.

Both tools have now been used in the field to full satisfaction.
