Wind turbine blade transport trailers are a crucial part of the wind energy industry, playing a vital role in transporting massive blades to wind farms.
These trailers are custom-designed to handle the weight and size of the blades, with some weighing up to 50 tons and measuring 80 meters long.
The transportation process is complex and requires careful planning to ensure the blades are delivered safely and efficiently.
Specialized trailers with hydraulic systems allow for precise control over the blade's movement, reducing the risk of damage during transport.
Wind Turbine Transport
Wind Turbine Transport is a complex process that requires specialized equipment and careful planning. Wind turbine blades can reach up to 70 meters in length, making transportation a significant challenge.
Transporting these massive blades on public roads can be hazardous, especially during natural disasters. Traffic police must be notified in advance to ensure safe passage.
SinoTrailers, a manufacturer of specialized transport equipment, offers wind blade trailers that can accommodate different blade sizes. These trailers are designed to withstand enormous loads and are equipped with advanced steering systems.
Wind turbine blade transport trailers are now widely used in wind power projects around the world. They provide strong support for keeping projects on schedule, even in complex terrains and inclement weather.
In addition to wind blade trailers, custom-made trailers are also available for wind power industry use. SinoTrailers provides a one-stop solution for all kinds of difficult transport jobs.

Safety and Logistics
Transporting super long windmill rotor blades on public roads requires careful planning and execution. Natural disasters can affect transportation operations, causing great difficulties in transportation units.
Traffic police should guard transportation in advance to avoid possible accidents during transportation. The transportation and protection vehicles must investigate the road conditions in advance to determine the safe traffic direction to enter the wind power site.
Each vehicle is equipped with a particular vehicle commander responsible for the cars' safe operation on-site.
How to Safely Transport Long Windmill Rotor
Transporting long windmill rotor blades requires careful planning to avoid accidents. The blades can reach up to 70 meters in length.
The transportation process is often hindered by natural disasters, which can cause significant difficulties for transportation units. Traffic police should be notified in advance to ensure safe passage.
Transportation and protection vehicles must investigate road conditions before entering the wind power site. This helps determine the safest traffic direction to take.
Each vehicle involved in the transportation process should have a designated commander responsible for ensuring safe operation on-site.
Disadvantages
The blade's overlength can be a real challenge. Due to its length of more than 70 meters, the steering radius is big, making it difficult to navigate tight spaces.
Transporting these blades to mountains can be particularly tricky. The U bends on mountain roads can be a problem, and in some cases, it's necessary to use a special trailer to get them through.

The cost of transporting these blades can add up quickly. The blade adapter is more expensive, and the low bed trailer is also specially designed, making its cost higher than a normal lowbed.
Using a specialized trailer can be a necessary expense. It's a small price to pay for the safety and security of getting these large blades to their destination.
Components and Technology
The self-steering jeep dolly trailer is a key component of the DOLL wind blade transport system, designed for efficient and safe transportation of wind turbine blades. It's available with 4 and 5 axles, and can even be extended with a 2 axle jeep dolly for added versatility.
This trailer is compatible with trucks from any manufacturer, making it a convenient option for wind farm operators. The bolted rocker bearing allows for individual adjustment of the swivel radius, ensuring smooth and precise steering.
The trailer's design also features a hose package that's stowed on the lifting adapter when not in use, saving space and reducing clutter. A high-quality coating is available in two options: a two-layer paint finish or spray galvanising.
Air Suspension

Air suspension is a viable option for wind blade trailers. It can use mechanical spring suspension, hydraulic suspension, or air bellow suspension.
The air suspension is best suited to protect the windmill blade from possible shock during transportation. This is because it can absorb and distribute the shock more effectively than the other options.
Air bellow suspension, in particular, is well-suited for wind blade trailers. This is because it can be designed to handle the unique stresses and loads associated with transporting large windmill blades.
Extendable Telescopic Beam
The extendable telescopic beam is a game-changer for wind blade transport. It can extend up to 62 meters, allowing for efficient transportation of long blades.
The sliding pneumatic locking system on both sides ensures that the beam stays in place while extended. This is crucial for maintaining the brake system and illumination system.
A 2.5KW power pack system makes steering easy, even with the extended beam. This is a significant advantage over traditional trailers that struggle with maneuverability.
The telescopic beam design allows for flexible adjustment to the actual length of the blades, making it ideal for handling blades of varying lengths.
Here are some key features of the extendable telescopic beam:
- Extends up to 62 meters
- Sliding pneumatic locking system on both sides
- 2.5KW power pack system for easy steering
- Flexible adjustment to blade length
Choosing the Right Trailer
Choosing the right trailer for wind turbine blade transport is crucial to ensure safe and efficient transportation. The size of the trailer should meet the length and width requirements of the blades, and it's essential to choose a trailer that is scalable to accommodate different sizes of wind turbine blades.
The load carrying capacity of the trailer is also vital, and it should match the maximum load carrying capacity of the wind blades. For long distances, air or hydraulic suspension will provide a smoother ride, reducing the risk of damage to the blades or the trailer.
A windmill blade transport semi-trailer can be more than 60 meters long, and it's equipped with a hydraulic steering system to overcome the increased turning difficulty. The rear axle is often fitted with a power station, and the air suspension system ensures stability and good trafficability.
Selecting the Proper Trailer
When transporting wind turbine blades, it's essential to choose a trailer that meets the length and width requirements of the blades. The size of the trailer is crucial, as wind turbine blades can be up to 60 meters long.
The load carrying capacity of the trailer is also vital, matching the maximum load carrying capacity of the wind blades is essential. A trailer with a load carrying capacity of 60 tons or more can handle large wind turbine blades.
Air or hydraulic suspension is recommended for long distances to ensure smoothness during transport. This helps to reduce wear and tear on the trailer and the wind turbine blade.
Driving as a drawbar trailer can save time, money, and reduce fuel consumption. It's also possible to drive empty without a separate special permit, making it a convenient option for transportation.
Customization options are also important to ensure the trailer performs well in all conditions. This includes features such as remote control power steering and a mass balance block to balance the force on the front and rear axles.
The trailer's design should also consider the stability and length of the windmill blade. A trailer with a height of 550 mm and a width of 300 mm can provide a stable and secure platform for transporting wind turbine blades.
Low Loading Height
Low loading height is a game-changer for wind blade transport. The trailer offers the lowest loading height of any transport system on the market.
This means you can easily load and unload your wind blades without straining your back or needing a tall ladder. The low loading height makes it a breeze to transport your wind blades.
In combination with the low pendulum frame, you can make your wind blade transport even easier and more efficient.
