The self-steering 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.”

Joachim Wiesiollek, Managing Director of Transannaberg sp. z o. o.

Our quality sets the standard – mile after mile, on any terrain.
First successful test loading of the prototype wind blade Enercon E-175 EP5 carried out by DOLL

The rotor blade of the E-175 EP5 turbine is the longest that ENERCON has ever developed and produced. DOLL was the first manufacturer of wind blade transportation systems to successfully carry out the transportation of the new ENERCON wind blade.

Successful test run at Vestas

DOLL wind blade transport system proves itself during test loading and test run and is officially certified by Vestas.

Facts + components
  • Self-steering trailers with 4 and 5 axles, can be extended with a 2 axle dolly
  • Compatible with trucks from any manufacturer
  • Bolted rocker bearing with individual adjustment of the swivel radius
  • Hose package is stowed on the lifting adapter to save space when running empty
  • A high-quality coating of your choice: two-layer paint finish or spray galvanising
  • Lowest loading height of the trailer on the market
  • No additional adaptations necessary: Modular design of the interface on the lifting adapter facilitates installation of the wind blade
  • User-friendly attachment of the power unit: The unit is mounted transversely on the lifting adapter so that there is maximum space when the wind blade is rotated through

Perfectly linked with DOLL Powerboost

Convenient, time-saving and secure wiring along the side of the wind blade protects the load from damage caused by vibrations of the wire rope.

Low wear and tear when travelling empty

Driving as a drawbar trailer saves time, money and reduces your fuel consumption. In addition, empty driving is possible without a separate special permit. Coupling is simple and efficient, even on uneven ground.

Field-tested self-steering trailer technology

A rotating attachment and variable overhangs give your trailer almost unlimited maneuverability. Even driving offset to the side (known as “crab steering”) is possible.

Manual oversteering

And if things do get tight? Then simply steer with the radio remote control at any time. You can also raise and lower the lifting adapter by remote control and rest it on the dolly when driving empty.

Option: Jeep dolly

This equips your system optimally for the future – and for even heavier blades. The lifting adapter is mounted directly on the dolly.

Smart battery charging system

The smart charging system with display via the app ensures that the battery in the trailer is charged and maintains the voltage. This means that the trailer remains operable and controllable even in emergency situations.

Unmatched low loading height

The trailer offers the lowest loading height of any transport system on the market.In combination with the low pendulum frame, you can make your wind blade transport easier and more efficient.

Modular adapter system

One adapter for every wind blade model. A special pattern of mounting holes in the adapter allows quick and easy attachment and replacement of the adapters.

Smart sensors

Increased safety thanks to earlier warning signals while steering prevents lateral forces in the blade. Visual warning 5° before reaching the end position to prevent damage to the wind blade.

Easier operation and more convenience

The adapted positioning of the hydraulic levers on the lifting adapter makes operation easier and creates an ergonomic advantage compared to the previous model. All operating elements are only one arm's length away.
