Next, the use based on the configuration of the embodiment of the present invention will be described below. Since the folding slope 1 for a forklift vehicle is folded, the overall length is reduced to about half, it is possible to put it on a small truck, and put it on a small truck at a necessary place, for example, unload a luggage from a marine container. Or, it can be easily transported to the place where cargo is loaded on the marine container.

The folded slope 1 for traveling on a forklift vehicle that is placed on a light truck and conveyed to a predetermined place is lowered using a crane integrated with the light truck. Since the folded foldable slope 1 for running a forklift vehicle has a total length of about 3 m, it can be lowered using a crane provided in a small truck without using a large crane or the like.

The folded slope 1 for traveling on a forklift truck that has been lowered to the storage location of the marine container is returned to a predetermined length using a crane provided on a small truck.

That is, the crane provided on the small truck is used to rotate the bent intermediate inclined road surface 12 and the lower inclined road surface 13 while pulling them up in the full length direction. The intermediate running slope 12 is rotated downward with the center turning portion 2 as a turning fulcrum and returns from the upside down state to the original state, and the lower running slope 13 is set with the lower turning portion 3 as a turning fulcrum. It returns to its original state while rotating upward.

At about the same time, the crane provided on the small truck rotates the bent overhanging horizontal road surface 14 while pulling it up in the full length direction. The overhanging traveling horizontal road surface 14 rotates downward with the upper end folded portion 4 as a pivot, and returns from the inverted state to the original state.

The folding slop 1 for traveling on a forklift vehicle, which has been folded in this way, is then moved by the crane provided on the small truck to the upper traveling slope 11, the intermediate traveling slope 12, and the lower traveling slope. The inclined road surface 13 becomes straight with the same inclination gradient, and the horizontal road surface 14 for overhanging traveling is in a horizontal state, and a slope having a predetermined inclination gradient is formed.

Using the folding slope 1 for running a forklift vehicle that has been returned to its original state, the forklift vehicle travels thereover to carry out work to unload luggage from a marine container or load luggage into a marine container. Will be

When the unloading operation from the marine container or the loading operation to the marine container using the forklift truck is completed, the folding slope 1 for running the forklift truck is folded using a small truck crane. A small truck is placed and transported to a predetermined location.

The present invention is not limited to the embodiment of the present invention, and it is needless to say that various modifications can be made without departing from the spirit of the present invention. In the above-described embodiment, the case of bending at three places has been described, but the present invention is not limited to this.

[0045]

[Effect of the invention]

 As is clear from the above description, according to the folding slope for traveling a forklift vehicle according to the present invention, the folding slope for traveling a forklift vehicle becomes approximately half as long as it is folded. This makes it possible to place the cargo on a small truck and easily transport it to the required location, for example, to unload cargo from a marine container or load cargo into a marine container. In addition, when the folding slope for forklift trucks is mounted on a small truck or lowered from a small truck, it can be carried out using a crane integrated with the small truck. This eliminates the need for a crane and significantly reduces costs, which is an extremely practical and beneficial effect.
