Advantage of Telescopic Extendable Trailers:
Reliable and Efficient. Constructed of high yield strength material, telescopic trailers are reliable in terms of safety and general transportation needs.
It’s easy to use. The extendable truck trailer comes in a simple design that is easy to use and operate either hands-on or remotely. Loading and offloading cargo are made safe and simple for operators to manage the operations in an effortless manner.
It can transport other kinds of oversized cargoes, not only the blades and tower. Therefore, the user can put the extendable container chassis into many other uses other than for transporting wind turbine blades.
The wind turbines are getting bigger, so the blades are becoming longer as well. So far the wind blades can reach up to 70 meters. Natural disasters affect the progress of transportation operations, causing great difficulties in transportation units. The traffic police should guard transportation in advance to avoid possible accidents during transportation. After the wind power equipment is transported to the site, the transportation and protection vehicles must be required to investigate the road conditions in advance to determine the safe traffic direction to enter the wind power site.
