Products & Projects
Liftra Products Explore our best-selling lifting-, transport- and maintenance
equipment, products like Main Shaft Fixture, Rotor Yokes and Tower tacking
Frames is developed and produced for a wide range of turbine brands and
parts. In order to ensure our customers short lead time, we have storage space
in USA, Europe and China containing the products that are high in demand.
Each of Liftra’s projects is unique and developed with a specific customer
or task in mind. Projects may be initiated based on an idea, or arise during
development all the way to delivery. Liftra also performs structural analysis
tasks, certification tasks, and production of already developed designs.

of nacelle, ready for use
Liftra Self-Hoisting Crane
Changeing 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 change a gearbox.
Liftra Self-Hoisting Crane is liftet from container to nacelle, on
its own lifting wire
Crane, just below Jib, ready for installation on base
Compatibility
If you change the crane base, it can change gearbox
on the following turbines:
Siemens 2,3MW.
NEG Micon/Vestas NM72, NM82, V82.
Suzlon S88,
Vestas V80.
All turbines where the roof can be removed, the Liftra
Self-Hoisting Crane can be used.
Advantages of the Liftra Self-Hoisting Crane:
Reduces mobilisation costs significantly
Is able to operate in higher wind velocities
(up to 18m/s)
Gearbox exchange
Generator exchange
Exchange of main shaft fixture
Nacelle maintenance without the use
of mobile crane
Rotor exchange

Minimising risks
Work in higher wind speed
Fixture is assembled within nacelle
Ejector system automatically pushes off the gear box
A main shaft fixture can be assembled with the turbine crane without any need for
external main crane, and without dismantling the rotor is required. The main crane
capacity is significantly lower since it merely has to lift the fixture and the gear box.
All fixtures have an ejector system that pushes off the gear box with a force of up
to 30 ton.
In LIFTRA PRODUCTS we have a growing selection of more than 10 different main
shaft fixtures. For additional information please contact us.
For all the Liftra Main Shaft Fixture:

Suzlon S88 (2,1MW)
The fixture is delivered in a transport box including ejector system, fitting and custom tools. This ensures 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.

Tower Stacking Frames
Each set consists of 4 support feet, 2 frames and ladders. Using a fork lift, two feet are
assembled on the top tower section, and ladders are subsequently mounted.
Bottom section is mounted with feet and frames, and lifted to stacking destination
on ship. Following this, the top section will be lifted and joined with the bottom

Offshore
From the outset, Liftra has been part of the offshore turbine industry. Today, Liftra is one
of the major suppliers of Davit Cranes- Special lifting yokes for Blades, Nacelles, Towers and
platforms for several offshore projects. To read more about this in detail, visit the pages for
the specific offshore areas, and should you need further information, please contact us.
Liftra offshore projects comply with international standards and can be approved by DNV,
GL, LLOYD’S (and others). It is possible to modify most projects to be applied for offshore
purposes. Please contact us to get further information regarding this.
