Products & Projects
Explore our best-selling lifting, transportation, and maintenance products, including
main shaft fixtures, rotor yokes, and tower stacking frames. All are developed and
produced for a wide range of turbine parts and manufacturers. In order to ensure
our customers a short lead time, we have storage space in the US, Europe, and China
containing our high demand products.
Each Liftra project is unique and developed for a specific customer or task. Projects
may be initiated based on an idea, or based upon necessity, whether during development or through delivery. Liftra also performs structural analysis, certification, and
production of previously developed designs.

Liftra Self-Hoisting Crane
Changing major components without a mobile crane
The crane is designed for all turbines with gearboxes up to 24 ton and
where the roof can be moved back / removed without a mobile crane.
Only one 40 foot container is needed for transportation of the Liftra Self-Hoisting Crane, for installation and
replacement of a gearbox or generator.

nacelle using its own lifting wire

Fixture is assembled within nacelle
Ejector system pushes gearbox off main-shaft
A main shaft fixture can be assembled by the internal turbine hoist without the
need for an external main crane, and without dismantling the rotor. The main
crane capacity is significantly lower since it eliminates the rotor which is commonly the heaviest lift. All fixtures have an ejector system that pushes off the
gearbox with up to 30 tons of force.
Liftra has a growing selection of more than 10 different main shaft fixtures. For
additional information please contact us.

The fixture is delivered in a transport box and includes ejector system, fitting,
and custom tools. This ensures that all parts needed for replacement of the gearbox is in a single unit - minimizing down time on site. The transport box is weather proof and can be locked.
