[Effects] In this embodiment as described above, the towing vehicle pulls the trailer 1 to transport the pole transformer bodies 4 and 5 in the container 3 to the construction site. Then, once transported to the construction site, no tow truck is required. That is, the work vehicle equipped with the construction transformer does not always stop in the construction site where the repair and replacement work of the distribution line and the pole transformer is performed. As a result, the number of vehicles required for the construction can be reduced, the working space and the number of workers can be reduced, and traffic obstruction near the construction site can be eliminated and the setup work can be shortened.

Further, even if the trailer 1 of the present embodiment is separated from the towing vehicle, the trailer 1 can be moved independently by pushing or the like by an operator. Therefore, the construction transformer can be easily moved even when the construction site is narrow and the construction site is narrow.
Moreover, according to the present embodiment, since the towing vehicle for towing the trailer 1 is not equipped with a construction transformer, there is no work to be performed on the construction site after the trailer 1 is carried to the construction site. Therefore, other work can be performed. Therefore, the degree of freedom of the work is increased, and the work can be speeded up.

As described above, according to the trailer-type construction transformer of the present invention, the trailer is towed by an extremely simple structure in which a container accommodating the pole transformer main body is mounted on the trailer. By transporting the container to the construction site and separating the trailer and trailer after transport, it is possible to ensure a reduction in the working space and the number of workers. Further, even when the construction site is narrow, the trailer can be easily moved by the worker. Further, since the towing vehicle for towing the trailer does not have the construction transformer, it can be engaged in other work, and the degree of freedom of work is increased, which can contribute to speeding up work.
