Wind blade transport system | DOLL Fahrzeugbau GmbH

The DOLL^® wind blade transport system

The process of transporting wind turbine components is just as impressive as the turbines themselves. Getting giant wind blades around tight bends takes real specialists with exceptional equipment. It is for precisely this reason that we have deployed the over 100 years of experience we have in self steering dolly trailer technology to develop the DOLL^® wind blade transport system. A system that meets the highest quality standards and is able to adapt to the future of the wind energy sector and the transportation challenges you are set to face. And even more importantly: a system that is compatible with wind blades made by any manufacturer, without the need for adjustments. Big-name transport companies throughout Europe are already using this technology of tomorrow – today. When will you choose the DOLL^® wind blade transport system?

Features + advantages

For wind blades up to 100 m in length and 35 t in weight
From Nordex and Siemens Gamesa to GE, Vestas, Enercon, Suzlon – there are interfaces and adaptations available for every type of wind blade
Close collaboration with our partner HAWART
Built with high-quality components and well-known brand products
Field-tested self steering dolly trailer technology with a hydraulic steering system developed by DOLL^®
Extraordinary ground clearance and outstanding manoeuvrability
Sophisticated system for transport vehicles within the four-metre mark
Hardly any changes to road infrastructure required

The self steering dolly trailer for the DOLL^® wind blade transport system is a rapid series model that is available at short notice.

“Using the innovative DOLL^® system allowed us to transport the longest rotor blades, something that simply wouldn't have been possible with standard trailer types. The total length of the combined vehicle was 87.5 metres.”

Vehicle details and equipment

Facts + components

self steering dolly trailers with 4 and 5 axles, can be extended with a dolly with 2 axles
You can choose between a fixed, mechanical or hydraulic adapter solution
Compatible with towing vehicles made by any manufacturer
Low hitching point with a fifth-wheel load of up to 32 t
The lifting adapter can be mounted directly on the lorry or on the dolly
Screw-in rocker bearing adapted to the slewing radius required
Hose package can be stowed in the lifting adapter to save space
A high-quality coating of your choice: two-layer paint finish or zinc spraying

Lifting adapter with exceptional slewing abilities

The lifting adapter with torque bearing and rocker bearing allows the blade to rock consistently in its longitudinal direction. Even high centres of gravity can be driven absolutely safely.

Perfect connections thanks to DOLL^® Powerboost

Easy-to-attach wire rope connections ensure efficient cable connection clamping. This ensures the battery is permanently charged – without any loss of voltage.

Fuel-efficient empty trips

The vehicle can be driven as a drawbar trailer, which saves you time and money and reduces fuel consumption. In addition, empty trips do not require special approval.

Field-tested self steering dolly trailer technology

Practically unlimited manoeuvrability thanks to a rotatable attachment and variable wind blade overhangs. Even driving offset to the side (known as “crab steering”) is possible.

Manual oversteering

In a tight spot? The radio remote control allows you to adjust your steering easily whenever you need to.

Option: add a dolly

This way, you can ensure your system is perfectly equipped for the future – and for even heavier blades. The lifting adapter is mounted directly on the dolly.
