Chapter 1: What is an Extendable Wind Blade Trailer?

An extendable wind blade trailer, also known as a telescopic windmill blade transporter, is a special trailer for the transportation of wind turbine blades. These trailers can extend two times, three times, or even four times to transport 60 meters to 90 meters windmill turbine rotor blades or other super long items that common flatbed trailers can’t accommodate.

Chapter 2: Different Types of Extendable Telescopic Trailers

There are many types of extendable wind blade trailers in the world, now I just want to discuss China’s extendable wind blade trailer, why? because I’m from China extendable trailer manufacturer Hipotruk, and very familiar with China products. Alright, Let’s get straight to the point and dissect how many types of extendable trailers in China.

4 Axles Wind Turbine Blade Trailer (70m, 62m, 56m):

Unlike your common flatbed trailers, the 4-axles extendable wind blade trailer has extendable frames that can enable the trailer to stretch from 24 meters to 56 meters,62 meters, and even 70 meters. This adaptability makes it perfect for transporting windmill blades of varying lengths

The trailer is equipped with hydraulic turntable steering systems. This system allows the axles to achieve a steering angle of 25-45 degrees, making it easier for the trailer to steer, especially on curvy paths or narrow lanes. You can choose manual or remote control to control the steering systems.

For the suspension, there are mechanical suspension, air suspension, and hydraulic suspension for optional. The cost of mechanical suspension is budget-friendly, so you can choose according to your budget and your transport road condition.

When it comes to payload, this trailer doesn’t disappoint. In its closed state, it can handle loads over 40 tons – 60 tons. If fully extended, it can also carry 30 tons of cargo, making it easy to transport wind blades.

6 Axles Extendable Wind Turbine Trailer (Extendable from 60m to 70m):

Due to the different load requirements on axles across different countries, to meet load requirements, sometimes, the manufacturer has to increase the number of axles. That’s why the 6-axle extendable wind blade trailer comes into play.

This trailer can be stretched from 60 meters to a remarkable 70 meters after three or four-time extensions, making it easy to transport wind blades as long as 80 to 100 meters and weighing between 20 tons to 35 tons. It’s a perfect solution for those extra-long blades.

Its hydraulic turntable systems allow axles to achieve a 35-degree steering angle. This ensures the trailer can navigate even running on the most challenging routes, like narrow streets and sharp bends. Operators have the flexibility of manual or remote control for ease of operation.

The standard gooseneck is a popular choice for its low cost. However, there also has a hydraulic gooseneck for those who prefer it. For a suspension system, you have the choice between mechanical, air, or hydraulic suspension, depending on various load and terrain requirements and your budget.

8 Axles 10 Axles Telescopic Windmill Turbine Blade Trailer:

This trailer can stretch out to an impressive 63 meters after four-fold extension, it’s 24 meters when retracted. This versatility makes it ideal for carrying windmill blades ranging from 70 to 80 meters in length, and 20 to 30 tons in weight.

but why it has 8 axles and even 10 axles? because transporting heavy windmill components in countries with specific axle load limits can be challenging. For instance, some countries only permit a maximum of 10 tons per axle. To transport 80-ton cargo in such regions, a trailer with 8 axles and 10 axles becomes necessary.

Thanks to the hydraulic steering axles, the trailer can steer effortlessly, ensuring a smooth and secure transport of your wind blades or tower sections.

Hydraulic Modular Trailer with Telescopic Spacer:

This type of hydraulic modular trailer is equipped with a telescopic loading spacer for transporting massive wind rotor blades up to 100 meters in length and weighing 35 tons, as well as wind tower sections. It’s mainly used for transporting off-shore windmill turbine blades.

One of the standout features of this trailer is its advanced hydraulic suspension system, it can achieve a 45°- 55°steering angle, which is better than common extendable trailers ( can only achieve a 25°-35° steering angle), making it easier to navigate through challenging routes.

Besides, the loading platform height of the trailer is just about 0.7 meters in the Nicolas structure configuration. This is a considerable reduction compared to the 1.5-17 meters height typical of extendable wind blade trailers, greatly improving transport safety.

Chapter 3: The Specs and Designs of Hydraulic Modular Trailers

Chapter 3: Main Features & Components of Extendable Wind Blade Trailer

Okay, Now let me take you to explore the main structural features of the Chinese Extendable Wind Blade Trailer.

3.1 Gooseneck: Cranked, Straight & Hydraulic Gooseneck

Cranked Gooseneck: This design features a crank behind the front platform, allowing a lower height at the rear platform, and reducing load height.

Straight Gooseneck: Offers a uniform height between the front and rear platforms, ideal for specific transportation needs.

Hydraulic Gooseneck: It can be adjusted to accommodate various fifth-wheel heights on tractors. what’s more, when the truck steers, the hydraulic gooseneck can send the signal to the rear axles to steer in response to the truck’s movements, in other words, the axles will follow the truck’s movements, ensuring smooth navigation through tight bends and complex routes.

3.2 Construction Frame & Material:

The construction Frame of a telescopic trailer usually adopts high-strength steel like HG60, or Q550, so it can make sure the trailer’s telescopic beams remain stable and don’t sag when transporting heavy wind blades.

However, there some suppliers might go for cheaper steel, like Q456 or Q345 steel material which are mainly used for making normal trailers, to cut costs. Of course, it can save money upfront, and also appeal to some buyers who like cheaper prices, but it might not be the best in the long run. Cheaper steel could lead to problems like the telescopic beam bending over time, and you would have to spend more time and money to fix it.

3.3 Extension Mechanism:

Have you ever wondered why extendable trailers can handle various sizes of wind blades? The secret lies in their extension mechanism. This mechanism is a core technology for every manufacturer. In brief, it utilizes a combination of hydraulic and mechanical systems. This system allows the trailer’s extension beam to extend and retract to adapt to different sizes of wind blades.

Extension Beams (Telescopic Deck):
Wind blade extendable trailers stand out with their ability to stretch, offering three or four extension levels. This design allows them to transport rotor blades up to 90 meters long. Whether it’s triple or quadruple extending, the only Hipotruk trailer’s loading platform can extend beyond 70 meters in China, making it perfect for different lengths of windmill turbine blades. Below are components of extension beams for your reference.

Pulling Extension Platform:
Pulling it out with the towing vehicle, which is very simple to operate. You can extend it for longer blades or retract it for shorter ones, offering great flexibility.

Tail Extension Platform (Telescopic Deck):
This is located at the rear of the trailer and needs additional equipment, such as a truck head or forklift, to pull it out. Since it requires extra equipment to extend, the operation is more cumbersome.

Folding Extension Platform:
When not in use, this platform folds up neatly at the end of the trailer. If not needed, it can be removed.

3.4 Steering Systems:

When navigating tight spaces or tough terrains with wind blades, the steering system of your telescopic trailer is key. Here’s a look at the three primary steering systems in Chinese telescopic trailers.

Hydraulic Turntable Steering:

This is a common steering system for extendable wind blade trailers, This system can achieve 25° -35° steering angle. cust down on tire wear, easy to maintain, and also is a budget-friendly option for buyers. You can choose mechanical spring suspensions or air suspension combined with the turntable steering system according to your needs. The difference is air suspension can adjust the cargo platform’s height and also provide smooth driving experience.

Hydraulic Steering Axles:

Hydraulic steering axles can achieve 35° steering angle and make it great for making sharp turns without a hassle, but they have to wait for a command from trailer’s hydraulic gooseneck. When the truck turns, the gooseneck sends a single to the rear hydraulic steering axles, making the trailer’s axles work with the truck’s steering, helping the trailer follow along nicely. what’s more, these hydraulic steering axles it can adjust trailer’s platform height if it is equipped with hydraulic suspension.

Hydraulic Bogies:

Found on the bigger trailers with many wheels (multi-axle modular trailers), these help the trailer turn sharply, up to +/-55°, which is great for tight spaces. They also let you adjust the height of the load you’re carrying. While they’re super useful, they do cost a bit more than the other two systems.

3.5 Suspension System

The suspension system is vital for any telescopic wind blade trailer, as it absorbs bumps and shakes during transport, keeping those precious wind blades safe. There are several options to consider, based on what you need to carry, your local road laws, and how much you’re willing to spend. The most common ones include the leaf spring mechanical suspension, air ride suspension, and hydraulic suspension. Most Wind Blade Trailers go for mechanical suspension. Why? Because it’s cost-effective, durable, easy to maintain, and can handle tough roads like a champ.5

3.6 Braking System:

Transporting wind blades is no small task – they’re heavy and super important. That’s why you want a trailer with top-notch safety features. Think WABCO emergency relay valves and anti-lock braking systems (ABS). These aren’t just fancy extras; they’re lifesavers. They keep your trailer from skidding, making sure those blades stay put all the way.

3.9 Braking System:

These trailers are normally equipped with a compressed air brake system, including double brake chambers, WABCO relay valves, and ABS for safe operation. but please note that not all suppliers can use WABCO and ABS, to save cost, some suppliers would choose normal accessories to replace them, but you know it will reduce driving safety.

Chapter 6: How to find a reliable extendable trailer manufacturer from China.

As an overseas buyer, choosing a reliable wind blade extendable trailer manufacturer from China could not be an easy task. You can find many suppliers in the same industry easily, they provide the goods with different prices and quality. However it is not easy to figure out which supplier is better. Below are a few guides for you to find a reliable extendable telescopic windblade trailer manufacturer.

6.1 Visit supplier website:

Before sending an inquiry, you need to visit their website first, which provides relevant information about their company’s introduction, what products they produce, production experience, production capacity, what quality assurance systems they have, employee conditions, and material supply chain.

Please note that if a supplier is displaying too many different product categories on their website, then most probably they are a mediator( middleman) Your safest bet is to choose a supplier that specializes in specific areas.

6.2 Contact potential suppliers:

After you make the request, then you can see how the potential suppliers are interacting with you. It can save a lot time and energy to communicate with a professional supplier, with their rich export experience, they can provide the best solution and products to meet your requirement, and provide you with their successful cases, product videos, and technical drawings according to your transportation needs. So that means there are fewer chances of misunderstanding happening which speeds up the product delivery process if you contact a professional supplier.

But if you find a mediator, most times a mediator takes longer to respond because they have to check your requirements and details from the actual manufacturer. Then it is not only a waste of your time, but also delays the whole delivery process.

6.3 The Proper Trailer Solution:

Extendable Wind Blade Trailers from different factories have their features: advantages and disadvantages.

When extendable wind blade trailer vendors are bragging about their trailer advantages, think twice about whether the advantage caters to your needs and outweighs its downsides, if yes, it is relatively a good solution.

There is no Perfect & flawless design. You have to balance out its merits and flaws. Be level-headed and detect it when suppliers try to brainwash you. Tips for picking up the extendable wind blade trailer, Try to ask yourself a few questions next time.
1. Do I need it or do I just want it?
2. Is this necessary? Or it overconfigured?
3. Which part is more of my concern? What’s the benefit of it? What’s the downside of this solution(or this design)?
4. Can this solution save my total cost? Or just saving my purchase cost, but bringing me a lot of never-ending trouble in the future ( repair & maintenance & unexpected failures )?

6.4 Supplier Pricing:

You can find extendable wind blade trailers at different prices in China, but the quality of these trailers is not in the same line. High-price extendable wind blade trailer means higher quality Since price equates to quality in most cases. Especially when you buy something from China, to win an order, some bad suppliers or factories can offer you an unbelievably low price.

But we all know that the price does reflect quality, high-quality raw materials, and durable parts are often more pricey than ordinary parts. anything too low means poor quality or fraud, and the low price could turn out to be never-ending trouble ( high repair and maintenance costs or even having to buy a new one) in the future.

So it is best to make a comparison in prices of the same extendable wind blade trailer with different suppliers. you don’t need to compromise on the quality of the trailer when trying to save costs but try to balance quality and your budget.

6.5 Visit Factory, Quality level and Delivery time:

If you have one, two, or three potential suppliers, you still cannot decide which one to choose. Then it is best to visit the factory in person and test or inspect their wind blade extendable trailers. However, during the coronavirus pandemic, you may not visit China, but you can also make the video conference at least with your potential suppliers.

Be ready to ask for the information you want to know, communicate with their technical engineers about what type of wind blade extendable trailer they produce, and confirm whether their extendable trailer can meet your transportation needs. besides, ask your suppliers whether they arranged to make a quality test that their extendable trailer before delivery so that you can know whether their wind blade extendable trailer can meet your transportation needs.

What’s more, It is a good time to negotiate the price with your supplier when you visit them. you probably meet their top management to get a better price and shorter delivery time.

6.6 Check the supplier’s significant customers

If you find that the supplier has worked with a well-known company in your local area, it means that considerable customers trust this supplier and are very worthy of cooperation. Many factories in China produce high-quality products, but they usually cooperate with trading companies and sourcing agents, which means that these factories sell their products to abroad markets through third parties.

To protect their customers’ information, these third parties will certainly not share their customers’ information with these factories, so these factories are not able to provide their foreign customers information if you ask. but it doesn’t mean their product quality is not good, on the contrary, they not only can provide you with a high-quality product, but may also good price some time. (sometimes although you can find these factories, they may not provide a better price to you, because your purchase quantity may not be larger than their trading companies or agents at the beginning, and they have cooperated the the trading companies or agents for a long time, they don’t want to break their cooperation agreement )

In a word, if the supplier can’t provide customer cases or their customer’s contact information near your local areas, you still could ask them to provide what kinds of products they produced for their customers before and ask them to provide you with more product videos, product photos, production workshop video, and quality test video, etc.
