されない。In recent years, steel pipes having a diameter of more than 3 m are sometimes used. In the case of a steel pipe press-in / draw-out apparatus intended for such steel pipes, their vertical and horizontal outer dimensions are used. If the smaller one is the width, it is difficult to make even the smaller width less than 3.2 m. On the other hand, under the current law, the width of the moving object on the road must be 3.2 m or less, and the same as in the case of the small-sized steel pipe press-in / draw-out device, it can be used as a carrier for trucks and trailer vehicles. Simply loading the steel pipe press-in / draw-out apparatus having a large width described above does not permit transportation.

法が採られている。On the other hand, in this steel pipe press-in / draw-out apparatus, a portion for rotating the steel pipe has a structure using a large gear which is a precision part and a small driving gear which meshes with the outer teeth of the large gear. These assemblies require high dimensional accuracy. Therefore, there is a problem that it is difficult to assemble the apparatus even when disassembling the apparatus and transporting each part so as to be within the above-mentioned dimension of 3.2 m. For this reason, at present, the parts that can be easily disassembled and assembled, such as the deck attached to the device, are removed, the height of the device body is reduced as much as possible, and then the device is mounted on the carrier of a transport vehicle equipped with a tilting base. A method is adopted in which the main body is inclined and fixed so that the apparatus main body is transported so as not to protrude from the carrier of the carrier vehicle.

There's a problem. In addition, the main body, which is a heavy object, is placed at about 45 ° on the carrier of the transport vehicle.
It is necessary to lift the device body in an inclined state from this loading platform and install it horizontally at the destination,
There is a problem that it requires difficult crane operation.
