Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for loading cargo onto a truck, in which the interior of the surgery box is horizontally partitioned into multiple stages according to the size of the cargo, and the cargo is efficiently stored. It is.

Conventionally, the inside of a cargo box in a freight vehicle is formed of only one space, and when loading small cargo, it is necessary to gradually load the cargo from the back of the box, and to maximize the space above. It was necessary to stack stable items at the bottom in an orderly manner.

This makes the loading process into the drop box extremely complicated.
It takes a lot of work, and furthermore, if the packages are not of the same shape, there are many gaps, that is, a dead base between the plums and the package, which reduces the amount of cargo to be loaded, resulting in poor work efficiency.
Furthermore, since the loading work is carried out in a narrow space within the guard box, many workers cannot do it all at once, which poses the problem of requiring a very large amount of time. Therefore, attempts have been made to store pallets in multiple stages within the cargo box of the car body (for example,
No. 644), each stage is a fixed stage, and there are still problems to be solved in order to raise and lower the pallet while it is housed in the guard box.

Another idea is to install a floor plate inside the bridge box of the vehicle body so that it can be raised and lowered, and to lock the floor plate in the middle of the cargo box (
For example, Tsubaki Sekisho No. 49-196412) does not consider solving the problem of storing loaded floor boards in a shipping box because the floor boards have a structure that makes it difficult to carry them in and out. The present invention has been made in view of this point, and after loading the loaded items all at once on a loading platform approximately the same size as the floor surface of the plum box at a loading/unloading area outside the loading box, To provide a method for loading cargo onto a freight vehicle, in which the platform is directly carried into a cargo box via a transfer device, and the carried cargo platform is hoisted and locked so that it can be stored in a plurality of stages.
