BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a freight vehicle, and more particularly, to a freight vehicle that allows a small number of people to easily carry in and install a cargo at a consignee.

[0002]

2. Description of the Related Art Today, with the development of road networks, transportation by freight cars has become the mainstream of land transportation. Transportation by freight car is especially advantageous for transportation of freight such as precision machinery, electronic equipment, industrial robots, vending machines, etc. that are prone to malfunction or misalignment due to vibration, because it can be transported to the recipient without reloading. is there.

Furthermore, in recent freight vehicles equipped with an air suspension and a seismic isolation mechanism, vibrations are hardly transmitted to the cargo during transportation, so that adjustment work of the equipment after installation can be simplified or omitted. I have to.

For example, for cargo such as precision machinery, electronic equipment, industrial robots, vending machines, etc., the basic frame and the like are carried to the consignee together with the main body of the equipment, and at the consignee, first the basic frame is lowered to construct the foundation. After that, the equipment body is brought to the installation site, lifted using a lifting machine such as a crane or hoist, and lowered and installed while being aligned with the foundation.

[0005]

By the way, in the case of relying on human labor for the installation work of such equipment, a large number of workers are required in order to carry the cargo into the predetermined installation position at the consignee. In addition, since the weight is heavy, the work load on the worker is heavy.

[0006] In the present age of labor shortage, it is not easy to gather a large number of workers with such a heavy work load, and in order to solve the problem of labor shortage, it is preferable to use a carrier such as a forklift. It is common.

[0007] When there is no carrier such as a forklift at the receiving destination like in a new factory, a carrier or an installer carries a forklift in another freight car to handle the loading work.

Further, when there is no hoisting machine at the installation site, an installation company or a transportation company brings in a mobile crane to process the installation work.

For this reason, the carrier or the installation company has a freight vehicle for transporting the equipment body to the recipient, and
It may be necessary to dispatch a lorry for transporting forklifts, a crane truck, and a vehicle for transporting technical equipment for installation work.

Further, in this case, in order to carry-in and install at the destination, four drivers of these vehicles, two workers for loading and unloading forklifts, and slinging of a crane vehicle You must dispatch one hand.

Furthermore, about two engineers are required to direct and supervise the installation work, and one of them often serves as the driver of the vehicle for transporting the technical equipment for the installation work. .

That is, a lorry for transporting the equipment body,
In addition to the need for four vehicles, a lorry for transporting heavy goods for transporting trolleys, a crane truck, and a vehicle for transporting technical equipment, there may be a need for about nine people.
It is not uncommon to find it difficult to recruit this amount of staff due to lack of manpower.

Moreover, since the driver of each vehicle and the sling of the crane vehicle require a license, it becomes more difficult to secure human resources.

The present invention has been made in view of the above technical circumstances, and it is an object of the present invention to provide a freight vehicle that enables a small number of people to easily carry in and install a cargo at a consignee. To do.
