2. Description of the Related Art In the construction of buildings and the like, it is necessary to carry in and take out long construction materials such as long board materials, light iron materials or aluminum sliding (ALC). A plurality of trolleys are arranged in a line according to the length of the material, and the long material is lifted and transferred to the trolley by a hoist or a freight lift, and then the trolley is pushed and pulled manually. To move the long material.

[0003] A bogie is generally known in which wheels are provided at four corners of a flat base, and so-called casters are used for the wheels so that they can move freely.

[0004] For example, Japanese Patent Application Laid-Open No. Hei 8-1199591 (B66F 9/06) discloses that a long material is placed on a special long pallet, which is lifted by a hand pallet and a bogie is inserted into a gap below. In addition, a technique is disclosed in which the pallet is pulled by the hand pallet.

[0005]

However, such a conventional bogie has the following problems:
Arranging multiple carts in a row according to the length of the long material is time-consuming, and the work of inserting and setting the carts in the gaps lifted by hand pallets is also time-consuming. There is a problem that a large amount of labor is required to move the robot manually, and the workability is poor.

When moving a train of trucks, the width of the passage may be sufficiently wide in an outdoor yard. However, since it is a construction site, it is often necessary to convey a narrow passage or a corner in a building. For this reason, when moving by human power, it is necessary to pay attention to contact etc. to prevent damage to the material, so the burden on the worker is large, and if the attention is distracted, the worker may pinch his hands or hurt his lower back There was a risk of causing accidents and injuries.

[0007] In view of the above-mentioned conventional problems, the present invention eliminates the need for manual work, saves labor, and makes it possible to carry out the operation of transporting long materials safely and easily with an operator on board. It is intended to provide a long material transport vehicle.
