The continuing rise in size of wind turbine components has prompted Mammoet to buy its first ultra-wide onshore wind tower clamp set. The flexibility of these units will allow onshore wind transport projects to proceed with fewer modifications to verges, street furniture or bridges. 

It also allows new, larger designs of wind turbine generator to reach remote wind farm sites – where winds are strongest and most reliable – much more efficiently.

Mammoet will receive additional three ultra-wide onshore wind tower clamp sets from the fabricator Greiner before the end of the first quarter of 2022.

As developers seek to make the most of wind farm locations, turbines have grown taller to reach stronger, uninterrupted winds. Consequently, the base tower sections of these turbines have widened, from around 4.5 metres just a few years ago to over six meters today.

So, their center of gravity during transport has risen higher and higher from the ground; as much as 1.5 metres above earlier models. Beyond 4.5 metres, conventional trailers are considered not stable enough to perform transport of the largest tower models safely.

For these larger tower sections, the only alternative has been to transport them on top of a trailer with hydraulic suspension. However, this combination needs crane loading and unloading, is far less manoeuvrable and has a ride height 1.2 higher than a clamp solution; well within striking distance of bridges.

Ultra-wide clamp sets

This new system, fabricated by Greiner, is installed on turntables between a mixture of an air suspension jeep-dolly and conventional multi-axle hydraulic trailers in the rear, forming a modular vehicle capable of completing narrow sequences of turns without leaving the road surface.

Like other clamp systems, the new system can receive tower sections directly from supports – no cranes are required at any stage of the journey. During projects, it will be used to transport the lower, wider tower sections, while higher, thinner sections will be transported by existing clamp systems.

The new system transports up to 6.3 metres wide tower sections at lower overall heights than conventional trailers, and is already in active use. As the world transitions to more sustainable energy sources, Mammoet’s will continue to invest in equipment that makes this work safer and more efficient to undertake.
