Use a Fixture:When

Changing gear box.There is no space for rotor to be grounded (mountains, forrests, land owners etc.)

Gearbox is jammed.

WhySave time.

Save grounding costs.Minimize risks.

Work in higher wind velocities.

How Fixture is assembled within nacelle.

Ejector system pushes off the gear box.Change of gear box.

Fixture is removed from nacelle.

REDUCE MOBILIZATION COSTSA main shaft fixture can be assembled with the turbine crane. No need for early mobilization of external crane. No rotor dismantling required. Saving early mobilization of main crane.Main crane capacity is much lower since it must lift only the fixture and the gear box.

Ejector SystemAll fixtures have an ejector system, that pushes off the gear box with a force of up to 30 ton.

Custom fixtures can be designed on requestLIFTRA engineering team is specialized in lifting, transportation and handling of heavy components within the wind turbine industry. We are familiar with both components and their route through production to on-site installation and maintenance. Liftra is recognized by the international wind turbine industry as a specialist in lifting and transportation equipment. We guarantee excellent engineering and equipment production in our field.

Proven Technology Liftra has designed and produced more than 5 different main shaft fixtures and has more than 9 years of experience, and per-formed wind/load calculations for all rotor sizes and types. Liftra produces Main shaft fixture for all Siemens 2,3MW turbines, to fix the main shaft when the gearbox is changed. With the main shaft fixture the rotor does not have to be placed on ground, the gearbox can be changed in higher wind and the risk is reduced doing the operation. The ejector system ensures easy dismantle of the gearbox from the main shaft with a pushing force of up to 30 ton.

Complete with AccesoriesThe fixture is delivered in a transport box including ejector system, fittings and custom tools. This ensure that all parts needed for change of gearbox is in a single unit - minimizing waiting time on site. The transport box is weather proof and can be locked.
