BACKGROUND ART Conventionally, there have been cargo vehicles such as trucks with simple cranes attached to them. The simple crane had a mounting location between the operator's cab and the loading platform, and the simple crane was attached to the frame at this mounting location. Although it is possible to remove this simple crane, in reality it was not possible to remove it. In particular, although a simple crane is not required depending on the type of cargo on the loading platform, the crane is always mounted on the axle during operation.
This results in extremely uneconomical transportation conditions, which is a major problem.
