2. Description of the Related Art In the first stage of transportation of materials for construction / civil engineering work sites, major transportation is performed by mechanical force such as large trucks, cranes, and lifts. When it reaches the transportation stage, it relies on human power transportation, and a unicycle called a cat with one pneumatic tire and a trolley with four solid tires are commonly used. Cats have a deep-bottomed bucket shape and are suitable for transporting fluid materials such as concrete, mortar, sand and gravel, and formwork hardware, and small parts such as nails and bolts. On the other hand, the carrier truck is suitable for transporting finishing materials such as plywood and ceiling walls, and plate-shaped or lump-shaped materials such as concrete blocks.

Since a cat is a unicycle and requires a skill to run, it becomes easier to handle it if it gets used to it, and since it is equipped with pneumatic tires, it can be used on scaffolding boards or on concrete concrete. It can run in a fairly wide range such as on a roadbed that has been compacted. Since the carrier is a four-wheeled vehicle, it is easier to drive more stably and does not require any learning, but on the other hand, it does not turn small and it is a solid tire.
Suitable for running on a solid, smooth plate such as a skeleton concrete.

[0004]

On the other hand, in the case of traveling on an uneven terrain, a soft ground, a sandy ground, etc., the transportation means of both the cat and the carrier may have tires buried or tires removed. Therefore, there is a problem in running. In addition, running on vegetation such as vegetation or lawn has an adverse effect on vegetation and vegetation, and therefore cannot be run without protection.
For these reasons, scaffolding boards, plywood, etc. are usually laid and run on top of them, but the work of laying and removing the scaffolding boards, plywood is required, which requires materials and labor. Furthermore, when these materials are spread, a step is formed at the overlapped portion, and the traveling becomes unstable when passing through the portion.

These defects have a width of usually about 1,5 m which is provided in the middle of the slope in the height direction in order to maintain and inspect the slope and prevent the slope from collapsing. This was remarkable when working on the horizontal part, so-called small steps, and its solution was desired. Vegetation such as grass and trees is placed on the small tier, and drainage channels are generally installed. Therefore, both the cat and the carrier are required to be lined up with scaffolding boards for protection of vegetation and running over drains in the small transportation work on the small steps, and the work of laying and removing them is necessary. Therefore, it requires materials and labor, and traveling on the step of the overlapping portion of the scaffolding plates laid out is unstable and hinders. Therefore, it is desired to solve the problem.
