to grow. While the second- generation MWT-XL could already handle larger tower segments than the original MWT (it can accommodate segments with an inner diameter up to 5700mm), the third-generation MWT-XXL can transport an even wider range of segments, with inner diameters from 2850mm to 6100mm, without needing adjustments to the mounting frame. This is achieved through a
double, hydraulically height- adjustable A-frame. The load is clamped using a unique three-point system giving what Nooteboom claims to be the easiest operation and shortest loading/unloading times on the market. The load capacity is approximately 100t and the empty trailer remains well below four metres in height.
STABLE SUSPENSION Nooteboom has chosen air suspension for the new trailers – for good reason. As wind turbine components become larger the height of their centre of gravity also increases. This means additional trailer stability is needed for safe transport. Trailer suspension, therefore, becomes a key issue.
In addition to standard
theoretical calculations Noteboom also conducted stability tests at

the RDW test track in Lelystad in the central Netherlands to examine the differences in road behaviour between air suspension and hydraulic suspension. The tests revealed that the new 2.84m wide Nooteboom self-steered dolly with air suspension is at least as stable as a comparable trailer with hydraulic suspension and pendulum axles. Moreover, with air suspension,
the driver receives a visible warning in advance if the vehicle starts to lean over. In the case of a self-steered dolly with hydraulic suspension and pendulum axles the

MWT-XXL easy operation, low maintenance costs, and a low dead weight, says Nooteboom. The total weight of the loaded combination generally remains below 150 tonnes. Another advantage is that when an air-suspended axle compresses fully due to large road irregularities, pressure remains in the suspension system, allowing the other axles to continue bearing the load. In such situations with hydraulic suspension the pressure in the suspension system is lost and the compressed axle is much more overloaded. Lastly, air suspension is more environmentally friendly, simply because the vehicle uses less hydraulic oil.
