BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a work for loading and unloading cargo at a stepped portion, for example, a work for unloading cargo from a container car to a platform in a refrigerated warehouse,
The present invention relates to an apparatus for transporting cargo or the like, which is preferably used to form a forklift passage, a conveyor passage, or the like in a cargo loading operation from a platform into a container vehicle or a cargo loading operation into a platform during conventional cargo handling.

[0002]

2. Description of the Related Art Conventionally, a forklift passage is formed for transporting cargo between a platform and a container vehicle in a cargo loading operation from a container vehicle to a platform and a cargo loading operation from the platform to the container vehicle in a cold storage. If you do, as shown in Figure 8,
A horizontal table base D is arranged on the platform E in close proximity to the cargo loading surface C of the container B of the container vehicle parked in the truck yard A, and a slope base F is arranged on the platform E in succession to the table base D. The table base D and the slope base F are arranged and used as a forklift passage. Above table stand D
The slope table F is an assembly type, which is stored in another place when not in use, assembled when used, and installed in a predetermined place.

Further, as shown in FIG. 9, a power-driven slope mechanism G is also installed on the platform E. The slope mechanism G includes a slope plate H and an elevating device I for elevating the tip side of the slope plate H by power. The slope mechanism G is of a fixed type, and when not in use, the tip side of the slope plate H is lowered so that the upper surface of the slope plate H and the floor surface of the platform E are flush with each other. Then, at the time of cargo transportation, the tip end side of the slope plate H is raised to the height of the cargo loading surface C of the container B by the lifting device I, and the upper surface of the slope plate H is used as a forklift passage.

[0004]

The means for forming the forklift passage shown in FIG. 8 is installed after the table base D and the slope base F are carried to the installation location during use and assembled according to the height of the cargo loading surface C. Therefore, it takes a long time to form the forklift passage, and a storage space for the table base D and the slope base F is required. Therefore, an extra space is required. Further, when the drum can is carried out from the container B, a reach type forklift with a small turning ability is often used. However, the reach type forklift has a low climbing ability, so that the slope stand F having a steep slope may not be able to climb.

In the means for forming the forklift passage shown in FIG. 9, since the formed forklift passage has no horizontal portion, the cargo cannot be conveyed horizontally near the exit of the container B. Therefore, when the cargo is loaded near the ceiling inside the container B, the cargo J is inclined near the exit of the container B during transportation as shown in FIG. 9, and the upper surface of the cargo J may be inclined depending on the inclination angle. It may be difficult to load cargo when it hits the ceiling, or the container B
It was sometimes difficult to load cargo near the exit inside.

In a refrigerated warehouse, cargo may be transported between a container car and a platform by using a van ejector and a van eject conveyor. In order to enter the interior, it was necessary to match the level of the entrance floor of the van unloader with the cargo loading surface inside the container car by using a dedicated lifting device. Also, in conventional cargo handling, cargo received on the truck yard may be transported to the cargo sorting work area inside the platform using a forklift.However, since the passage of the forklift is cut at the step, the forklift is It was necessary to transfer cargo between each other or to transport cargo by a wheeled cart.

As described above, in the cargo transportation work in the refrigerated warehouse, conventionally, the equipment is selected according to the type of work to form the forklift passages and the conveyor passages of various modes. The process of forming the passages is complicated, and problems may occur in the formed forklift passages and conveyor passages.

The present invention has been made in view of the above circumstances, and conveys cargo or the like in which it is possible to form a forklift passage or a conveyor passage of an optimum mode corresponding to the type of work by one device. An object is to provide a device for use.
