Features of extendable lowbed trailers
The wind blade trailer adopts the pulling structure to extend the length, and the wind blade lies flat on top of the trailer.
The significant feature of the wind blade transport extendable lowbed trailer is that it is super long and has longitudinal expansion and contraction. Due to the super length of the vehicle type, the turning difficulty is significantly increased. To overcome driving on the curve, the wind blade transport vehicle is generally equipped with a hydraulic steering system, and the rear axle is fitted with a power station.
Considering the stability and the length of the windmill blade, the rear axle adopts its air suspension system, drawing and pulling the longitudinal beam freely, and has good trafficability.
The windmill extendable low bed semi trailer of the blade can be more than 60 meters long. It has three or four axle balance type, remote control power steering, and a mass balance block is installed between the front and rear leaf springs, which can change the deflection of the front and rear leaf springs equally and balance the force on the front and rear axles.
The bearing capacity is designed as 60 tons or more, the height of the main chassis frame is 550 mm, the width is 300 mm, the girder is buckle box type, the side beam is 250 mm I-beam, and the minimum cargo loading surface is 850mm.

Hydraulic, air, and mechanical suspension can be options according to different road conditions and specific project requirements.
Suspensions of wind blade trailer could use mechanical spring suspension, hydraulic suspension, or air bellow suspension.
The air suspension would be best to protect the windmill blade from possible shock during transportation.
Hydraulic windmill blade is an extendable telescopic beam connect with a hydraulic modular trailer, axle numbers could be three or above to adapt different weights of the blades. In this case, the hydraulic wind blade trailer has a bigger steering angle compare to that of the airbag extendable trailer.
The hydraulic suspension blade trailer has a lower cargo platform height than that of the air suspension trailer, also the lifting stroke is wider. The hydraulic suspension has advantages so the cost is higher than the air and mechanical suspension blade trailer.
The mechanical suspension is strong and at low cost, hydraulic suspension is suitable for heavier cargo.
The photo shows the steerable axles(bogies). The hydraulic cylinders controlling the steering of the trailer.
Due to the length of the trailer(together with the blade) could reach up to 70 meters, the most suitable way to realize steering is by operator’s manually control.
Extendable telescopic beam
The telescopic beam blade trailer is extendable to 62 meters. Sliding pneumatic locking system for telescopic boom on both sides.
The reels of wire are air brake hose and electric wire, make sure the brake system and illumination system are working while the telescopic beam extended.
The wireless remote control panel enables the operator to steer the trailer in a safe and convenient way. Want to transport windmill on mountains? You need the blade adapter.
Wind-blade trailer vs. blade adapter trailer. Both trailers are using to transport windmill blades, but for different scenarios.
The extendable lowbed trailer has a longer length, we can lay down the blade on top of the trailer in a flat position. The cost of the trailer is lower.
Due to the overlength is more than 70 meters, so the steering radius is big. If we need to transport the blades to mountains, it will be difficult to pass the U bends. In this case, we have to use the help of the below blade adapter trailer.
Windmill blade adaptor trailer
Wind blade adaptor trailer is shorter, which means smaller turning radius, more suitable in mountainous terrain. Want to know more information about the blade adapter, please click here.
Need extra operator and observer to adjust the angle and position of the blade.
