Wind turbine trailer is a subdivision of special vehicles. It is mainly used to transport wind turbine blades. It is a semi trailer. Because it is super long, it generally adopts a drawing structure. The front section is drawn and the rear section is drawn. The longest Reach 45 meters. Because the whole vehicle is longer, hydraulic steering is generally used. The bridge system has two-line four-bridge structure and three-way bridge structure.
Extendable Wind Turbine Trailers for Sale in Vietnam
Wind turbine trailer, wind turbine blade trailer, wind turbine tower transport trailer, 35m, 42m, 45m, 56m hydraulic steering wind power equipment transporter, 16m-17.5m pull-out low flat semi trailer. Mountain blade transport tooling. The wind tuebine trailer, the 53-meter wind turbine blade trailer, as the name implies, is a vehicle used to transport wind power blades. The large feature of the wind turbine blade trailer is that it is super long and has a longitudinal expansion function. The super long model greatly increases the difficulty of turning. In order to overcome the difficulty of driving in curves, the vane transporter is generally equipped with a hydraulic steering system.
The extendable wind turbine trailer can be up to 50 meters in length, three-axis balanced, remote-controlled 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 by the same amount, and force on the front and rear axles Balance and so on.
The total length is 460,000/(17.5﹡22﹡6.5)X3000X1810m, it can be fully opened, the carrying capacity is designed according to 80 tons, the beam height is 550mm, the width is 300mm, the beam is buckle box type, the side beam is 250mm I-beam, the load surface is 850mm low, and the vehicle floor 4# tread plate, tire 11.00R-20.
This model is specially designed for transporting wind turbine blades and can be extended to 44 meters in length. Due to the length of the cargo itself, it greatly increases the difficulty of turning. In order to overcome the difficulty of driving in the curve, the rear axle is used, and the rear axle is used with the power station. At the same time, considering the stability requirements of the cargo, the rear axle is also developed by ourselves The suspension system cleverly solves the foreseeable difficulties in loading. This wind turbine adopts a secondary stretch of 23 meters and a rear pull of 5 meters to ensure a total length of 44.15 meters; it adopts a two-axis steering system, equipped with a small hydraulic station, manual operation to achieve steering, a large turning angle of 35 degrees; under the leaf spring Placement, low cargo table, easy drawing of the longitudinal beam, and good passability.
Wind turbine trailers include ordinary wind turbine blade trailer, axial wind turbine blade transport trailer, and lift-type wind turbine blade transport trailer. Let's introduce to you:
① Ordinary extendable wind turbine trailer is a bit similar to low bed transport vehicles, but the girder adopts a buckle box design. The girder is pulled to adjust the length of the vehicle to adapt to the transportation of vanes of different lengths. It is understood that the current domestic pumping The pull-type wind turbine trailer can be up to 50 meters long.
②The big difference between the axial wind turbine trailer and the ordinary wind turbine blade transport trailer is that the chassis adopts a hydraulic axis design, so that the vane truck has a lower cargo deck and more flexible steering.
③Blade lifter wind turbine blade transport trailer refers to a blade transport vehicle equipped with a hydraulic lifting device, which is mainly aimed at the transportation of blades in mountainous areas. In the case of flat roads, the blades are transported flat. In the case of extremely small turning radius in mountainous areas, the lifting device is used to raise the height of the transported items (usually 5-10 meters), and shorten the length of the vehicle to bypass obstacles.
The vigorous investment and construction of wind power generation in the national market has also driven the wind turbine blade and blade transportation industry, an alternative large-scale transportation industry. The semi trailers used for the transportation of wind blades generally include ordinary extendable wind turbine trailers, axial wind blade transport trailers and lift-type wind wind blade trailers.
The length of the wind blade is at least 30 meters, so the above-mentioned transportation method cannot be used in mountainous areas. What should I do? A semi-trailer specially designed to transport wind blades is a good solution to the transportation in the mountainous area of wind blades. It is different from the transportation on the vehicle "put" on it. This mode of transportation is similar to holding a big sword in your hand, which allows the wind blades to be transported. It moves in different directions up, down, left, and right to avoid various obstacles on the mountain road to meet the needs of wind blade transportation.
● Low center of gravity on the fixed base of the blades to ensure safety
Unlike conventional wind turbine trailers, this wind turbine trailer has a very short length, which is also to meet the requirement that the vehicle can normally run on mountain roads. You can think of it as a crane, with its walking part on the bottom and a turret on the top. The wind blades are like the boom of this crane.
The wind blades to be transported are fixed on the vehicle by bolts, and the wind blades and the base are firmly integrated. During the transportation process, the wind blades can move up and down and left and right without danger.
In order to ensure that the center of gravity is unstable when the blade is displaced, the back of the base can prevent counterweights to achieve the balance of the entire vehicle. The counterweights can be flexibly added according to the weight of the blades.
The trailer is equipped with 275/70R22.5 size tires, the purpose is to reduce the height of the entire vehicle, not only more convenient when loading and unloading, the lower height also ensures the stability of the vehicle during operation.
● Inspired by cranes, air conditioning improves comfort
The turret is fixed on the trailer, and the hydraulic motor drives the gear fixed under the turret to realize the rotation of the entire base. The turret can theoretically rotate 360° degrees.
With such a long blade, if the force generated by the front wind is very scary, if it is held high, it is very likely to overturn the transport vehicle. To solve this problem, the base can rotate along the axis of the blade under the premise of satisfying the lifting requirement, so that the windward side of the blade is always on the side with the smallest area.
