Accordingly, the pallet transport system and transport method using the rotating unit according to the present invention include a rotating unit that can collect/supply circulating pallets instead of using a lifter device of the prior art, thereby improving manufacturing convenience and maintenance. By improving the structure of the rail/roller frame considering the convenience, there is an effect of shortening the working time and improving the performance of the facility by the rotating unit that collects/supplys the circulating pallets.

That is, according to the present invention, the operating time of the entire facility can be shortened by shortening the time delay by the recovery/supply rotation unit of the circulating pallet instead of the lifting process by the lifter of the prior art, and in this way, the reduction of the operating time This has the effect of increasing production efficiency.
