Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a utility pole carrier for transporting long utility poles.

[0002]

2. Description of the Related Art In a conventional utility pole carrier 1, as shown in FIG. 5, a utility pole 3 is placed on the ground parallel to the side surface of a vehicle 2, and ropes 4 and 5 are hung on the front and back of the utility pole 3, respectively. 4,
By winding 5 on the winches 6 and 6, the utility pole 3 is pulled up along the side surface of the vehicle 2 while rolling on the road plate 7 and placed on the front and rear rests 8, and further on the rest 8 in the lateral direction. It is moved to a predetermined position while pulling. The front and rear rests 8 are connected by a connecting rod 9.

[0003]

The conventional utility pole carrier 1 has the following problems. 1. Since the electric pole 3 is pulled up or lowered while rolling along the side surface of the vehicle 2, there is a risk of dropping the electric pole 3 during work, which is a safety problem. 2. As the utility pole 3 rolls, the surface is scratched. 3. Since the thickness of the utility pole 3 is different between the base and the tip, the moving distance after one rotation is different, and it is difficult to move the utility pole 3 in parallel. The ropes 4, 5 are sandwiched between the electric pole 3 and the vehicle 2 and are therefore easily damaged. 5, since the weight of the base of the electric pole 3 is larger than that of the tip,
The weight of most of the electric pole 3 is applied to the rope 5 on the rear side. 6. It is difficult to align the front and rear positions of the loaded utility poles 3 uniformly. Since the 7 and the rest 8 move while the electric pole 3 is being pulled on the upper surface portion, the strength must be large so as to withstand this stress. 8. Since the front and rear rests 8 are connected by the connecting rod 9, it is not possible to place a load on the central portion of the loading platform.

The present invention has been made in view of the above circumstances, and an object thereof is high safety and easy operation.
The purpose of the present invention is to provide a utility pole carrier that does not damage the utility pole.

It is characterized by having a mounting device.

[0006]

According to the present invention, the mounting tables are provided on both sides of the crane device. On the mounting table located between the electric pole storage area on the ground and the crane device, if the crane device suspends the utility pole and lowers the position of the utility pole according to the mounting table,
Utility poles are placed directly on the platform from the utility pole yard. When a utility pole is placed on the mounting table on the opposite side of the crane device, the utility pole once mounted on the mounting table is moved. That is, the crane device is adjusted to the horizontal state. The elevating parts of the front and rear transfer devices are interlocked with each other to raise the electric pole mounted on the mounting table to a position higher than the crane device. Next, the front and rear transfer devices are moved over the crane device to the mounting table on the opposite side. Therefore, if the elevating part is lowered, the telephone pole is placed on the placing table on the opposite side.
