Wind turbine weighing between 100 and 130 tons, with a length of 8.5 to 9.5 meters, a width of 3.5 meters to 4.2 meters, and a height of 4.2 to 4.7 meters. Due to parameter limitations, the need for modular trailer to transport, generally adopts 10 axle multi axle trailer to use, when passing through the bridge and culvert, the transportation height can be fully reduced through the control of the hydraulic modular trailer, and when passing through the urban area, town, wind farm bend, through the hydraulic steering control, try to reduce the difficulty of transportation to reduce the cost of road construction, obstacle removal, etc.
● Hub
The wheel hub shape is like an irregular sphere, with a diameter of about 3.5 meters and a weight of 20 to 30 tons. Due to the small contact area with the body of the trailer, it is necessary to strengthen the lashing during transportation. The wire rope cannot be in direct contact with the equipment, and needs to be padded with linen cloth or rubber gasket.
● Wind Blades
In the 3.5MW to 5MW models, the blade length is between 60 meters and 82 meters, the tip diameter is about 2.8 meters, and the weight is about 25 tons. In the wind blade transportation of mountain wind farms, stretch trailer are generally used to centrally transport to the storage yard near the wind farm, and then the "blade lifter" is used for unified secondary transport. In the process of transport, the wind blade can rotate 360 degrees through the slewing bearing, and the maximum lifting angle of the rotor blade adaptor cylinder can reach 60 degrees, so that the blade can be raised, swinged, and rotated in the process of transportation, so as to avoid obstacles such as trees, mountains, cables, and buildings. The advantage of rotor blade adaptor is that the amount of road reconstruction work is reduced and the construction period is shortened.
● Generator
In the direct-drive wind turbine, the generator and the nacelle are separated, the direct-drive type is another technical route compared with the doubly-fed type. The 5MW model, the weight of the equipment is about 140 tons, the generator is cylindrical in shape, with a diameter of 6.6 meters.
● Wind Tower and Foundation Ring
Wind tower is generally divided into 3 to 4 ends, diameter 3.1 meters to 5 meters, length of 20 meters to 30 meters, weight of 30 tons to 90 tons, the use of wind tower trailer or tower adaptor transportation, due to the long distance between the prime mover and the wind tower trailer, in the mountain need to 480 horsepower or 540 horsepower prime mover to drive In the case of no high-power truck, the wheel loader is generally used to pull and assist to climb. In the process of wind tower transportation, climbing up the hill is the most difficult, because the wind tower body does not have an attached hanging point, the bundle can only be bundled with canvas belt or wire rope, when going uphill, it is easy to cause the tower to slide backward due to the slope is too sharp, and even cause it to fall off when the situation is serious.
