Distribution methods using ground lifters

The present invention relates to a logistics transportation method using a ground lifter, and more particularly, usually buried underground, and when the vehicle arrives at the corresponding position, ascends to the ground and replaces the vehicle for transporting the container. For this reason, the present invention relates to a logistics transportation method using a ground lifter to support a container in a state of being lifted into the air.

In general, logistics is short for physical distribution and refers to the flow of water from producers to consumers.

In recent years, the logistics industry has been recognized as an important driving force of the national economy, promoting fast, accurate, convenient and safe logistics activities, and the logistics industry should be systematically developed by harmonizing the government's logistics-related policies. In 2007, the Korean government became interested in logistics by enacting and implementing the Basic Law on Logistics Policy for the purpose of contributing to the development of the national economy by making the logistics system more efficient, strengthening the competitiveness of the logistics industry, and advancing and internationalizing logistics. It is increasing.

Transportation methods of such logistics include land transportation, sea transportation, air transportation, multimodal transportation, and the like. Logistics transportation in Korea is mainly performed by land transportation.
