When low height cargos occupy the truck bed, wasted space is created on the upper part of the truck bed. So, a container that can load low cargos in two tiers has been developed. Its outer dimension allows placing the content in 2 tiers × 2 rows in a 10-ton truck and its inner dimension can be applicable to the most of the pallets. Therefore, the new system can reduce the number of trucks for transportation and CO₂ emissions.
