Description

DETAILED DESCRIPTION OF THE INVENTION This invention enables containers and the like to be easily unloaded to a position lower than the normal unloading position (for example, a position lower than the ground level in a pit, etc.). Examples of the present invention will be described below. To explain this with a diagram, as shown in FIG. 1, 1 is a vehicle body, 2 is a cargo handling arm mounted on the vehicle body 1 so that it can be raised and lowered freely by a hydraulic cylinder (not shown), and the base is pivoted on the vehicle body 1 so that it can be raised and lowered. A base boom 4, a sliding boom 5 slidably inserted into the boom, a vertical arm 6 erected from the tip of the sliding boom 5, and a hook portion 7 fixed to the tip of the vertical arm 6. It is what it is.

8 is a container equipped with a moving roller 9 on the back side and an engaging tool 10 on the front side, and the engaging tool 10 has sliders 1 on both sides.
1, and can be slid up and down along a guide frame 12 provided on the front surface of the container 8, and is appropriately fixed at a desired position up and down with pins 13 or the like (FIGS. 2 and 3).

14 is a pit, which provides a loading/unloading area for the container 8.

Hereinafter, the operation of the present invention will be explained. When the container 8 is on the ground plane of the vehicle body 1, the engaging fitting 10 is attached to the guide frame 1.
However, when the container 8 is in the pit 14 as shown in Fig. 4, the position of the container 8 is too low compared to the car body 1. Even when rotated, the tip hook portion T does not reach the engaging fitting 10 of the container 8.

Therefore, when the slider 11 of the engaging tool 10 is moved upward along the guide frame 12 and fixed, the hook part 7 can be engaged with the engaging tool, so the cargo handling arm is moved counterclockwise in FIG. When it is rotated, it is pulled up from inside the pit 14.

If the container 8 is pulled up above the vehicle body 1 in this locked state, the container 8 will be in a floating state because the engagement position is high, so the front bottom of the container 8 will be in the bit as shown in FIG. 14 end or the rear end of the vehicle body 1, the container 8 is held in that position, the cargo handling arm 2 is adjusted to expand and contract, and at the same time, the engaging fitting is made slidable and shifted downward along the guide frame 12. When the container 8 is fixed at a predetermined position and the cargo handling arm 2 is rotated again, the container 8 is pulled up onto the vehicle body 1, stably installed, and transported in a running state.

Also, in the case of unloading, the purpose can be achieved by performing the above operations in reverse.

As described above, the present invention is significant because it enables operations such as lifting a container from a pit or unloading a container into a pit by a simple means of selectively moving and fixing the engaging fittings 10.
