Wind power is the use of air flow through wind turbines to mechanically power generators for electric power. Wind power, as an alternative to burning fossil fuels, is plentiful, renewable, widely distributed, clean, produces no greenhouse gas emissions during operation, consumes no water, and uses little land. The net effects on the environment are far less problematic than those of nonrenewable power sources.
Wind blade trailer is used for transporting wind turbine blade, which the biggest characteristic of having a longitudinal telescopic function. Usually, there are ordinary telescopic (extendable) wind blade trailer, multi-axle line wind blade trailer and lifting type ( see windmill mountain blade trailer on detail.)
The multi-axle wind blade trailer is three stretching to 19m in the front and pulling to 7m at rear to meet the total length of 42m. It adopts two axle lines steering system, is equipped with a small hydraulic station, manual operation to achieve the maximum steering angle 40 degree. It can transport single blade, two blades and three blades with short length.
