A conveying device such as a forklift, a cart, and the like has a structure having a wheel or the like in contact with the ground, and thus has an advantage that a carrying area of the article is relatively relatively free. However, in the case where the size of the article is large or the shape of the article is a large- And the transportation efficiency is extremely lowered due to the difficulty itself.

Further, when a large-sized article is transported due to a frictional force acting between the lower surface and the floor at the time of transporting the article, a transportation device such as a forklift, a cart, etc. requires a great amount of force during transportation due to its frictional force, There is a disadvantage in that the vertical load is excessively applied to the conveying device which causes damage or breakage of the conveying device.

For example, Korean Patent Registration No. 10-0163352 comprises a plurality of support elements for supporting the outer surface of a cylindrical article such as a cable reel, wheels provided on the lower surface of the support element, and the like so as to stably transport the cylindrical article.

However, according to this conventional technology, as described above, since the wheels are in direct contact with the ground, a great amount of force is required in transportation, and a vertical load is excessively applied to the supporting elements moving in the horizontal direction, There is a disadvantage that the wheels may be damaged or damaged.
