Vehicle details and equipment

Facts + components

• self steering jeep dolly trailers with 4 and 5 axles, can be extended with a 2 axle jeep 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 jeep dolly 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 jeep dolly when driving empty.

Option: Jeep jeep dolly

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

Pioneering steering technology

DOLL® turntable steering

Your vehicle responds quickly and directly to the steering movements of the towing vehicle. Two independent hydraulic circuits guarantee complete reliability in any situation.

Market-leading axle technology

DOLL vario®

Stable, robust and incredibly strong. The DOLL vario® axle is one of the most durable in the world.

In the world of wind power, the transport of blades is a crucial aspect. The sheer size and weight of each blade requires a customised trailer to ensure smooth transport. Wind turbine blade transport trailers are made for this purpose. They are specially designed to accommodate the transport of extra-long blades while ensuring safety and efficiency during transport. In this article, we’ll take a closer look at the design features and benefits of these trailers to help you better understand their importance in wind power projects around the world.

Wind Turbine Blade Transport Trailers are specialised transport vehicles designed to ensure the smooth running of wind power projects. They are usually of a telescopic design and can be adjusted in length to accommodate different blade sizes. In addition, these trailers are ruggedly constructed to withstand the enormous loads generated during transport. The trailers are also equipped with advanced steering systems and fastening devices to prevent the blades from shifting or being damaged during transport.

These trailers are now widely used in wind power projects around the world. Especially in situations where they need to cross complex terrains and inclement weather. Whether it’s long distance transport or urban street transport. These wind turbine blade transport trailers provide strong support to keep projects on schedule.

Telescopic design: The highlight of these trailers is their telescopic design. It can be flexibly adjusted to the actual length of the blades and can be extended up to 56 metres. No matter how long the blades are, the trailer can handle them with ease.

Sturdy frame: The frame is made of high-strength steel and is able to withstand great weight. It maintains excellent stability even under harsh road conditions.

Intelligent Steering System: To adapt to narrow city streets or rugged mountain roads, the trailer is equipped with an all-wheel steering system. This allows you to drive with ease and reduces difficulties when turning.

Three Suspension Options: We offer three different suspension options, including mechanical spring suspension, air suspension and hydraulic suspension. We will also recommend the most suitable suspension system for you to ensure that the blades are always stable during transport.

Reliable safety fixings: to avoid any accidents during the transport of the wind blades, the trailer is equipped with an efficient fastening system.

Trailer dimensions: Our trailers have base dimensions of 21,500 mm x 3,000 mm x 1,350 mm and can be extended to a maximum of 56 metres. It can be adapted to the different lengths required for wind blades and is flexible enough to cope with different transport tasks.

High load capacity: The trailer has a maximum load capacity of up to 60 tonnes, enabling safe and stable transport of extra-heavy wind turbine blades.

All-wheel steering system: Equipped with an all-wheel steering system with a 4-unit steering axle design. This allows the trailer to turn flexibly on narrow roads, greatly reducing transport difficulties.

Powerful: The trailer is equipped with a diesel-driven hydraulic power station to provide strong power. This ensures that the trailer is able to cope with all kinds of complex road conditions and guarantees transport efficiency.

Customised service: We offer a range of customisation options, including platform thickness, fastening devices, branding options, etc., tailored to your needs.

There are a number of factors to consider when choosing the right trailer for transporting wind turbine blades.

Firstly, make sure the size of the trailer meets the length and width requirements of the blades you are transporting. Depending on the size of the wind turbine blades, it is also important that the trailer is scalable.

Secondly, is the load carrying capacity, it is vital that you choose a trailer with a maximum load carrying capacity that matches that of the wind blades. The type of suspension is also a factor you need to consider. For long distances, air or hydraulic suspension will be more suitable to ensure smoothness during transport.

Furthermore, the design of the steering system should not be overlooked, especially in complex road conditions, where all-wheel steering can provide extra flexibility.

Don’t forget to choose the right customisation options to ensure the trailer performs well in all conditions.

The task of transporting wind turbine blades requires a trailer with the highest levels of stability and reliability, and Truckman Automobile’s low-bed trailers are optimised for this purpose. Our trailers provide the stability and flexibility to meet the most demanding transport requirements.

No matter how unique your needs are, we can provide individual customisation to ensure the most suitable solution for you. If you are interested in our products, please feel free to contact us for more information and support.
