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 ensuring that the logistics industry is systematically developed by harmonizing the government's logistics-related policies. In 2007, interests in logistics were enacted, which enacted and enforced 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 improving 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.

In this case, the land transportation means the transportation of cargo and passengers carried out by land or lake, river, harbor, etc., mainly by air transport using a freight vehicle to transport logistics through a road, and rail transportation using a railway vehicle. First of all, air transportation has the advantages of excellent maneuverability and quickness, easy to cope with various cargo characteristics, and flexible distribution, which is suitable for short-distance transportation.However, there is a high risk of accident and environmental pollution due to traffic jam and soot. There is a problem in that it is unsuitable for long distance mass transportation due to the high fare in the long distance transportation.

In addition, rail transport has the advantages of low risk of accidents, all-weather transportation, and low freight rates, making it suitable for medium and long-distance mass transportation, but consistent transportation of door to door Impossible, transshipment is required, there is a problem that is unsuitable for emergency transport and short-haul transport because the elasticity of the dispatch is low.

Therefore, the Modal Shift Policy (Truck Shift Policy) proposed to solve the problems of the domestic logistics transportation system, which is excessively dependent on air transportation, such as causing traffic jams and environmental pollution caused by vehicles. It is necessary to use a new concept of logistics transportation system that can improve the problems of railway transportation while complying with the policy of converting cargo used on the road by railroad or ship.

In addition, in the case of transshipment work for door-to-door transportation, the container must be lifted and moved one by one by using a crane, etc., and thus a lot of time is required for transshipment, and an accident may occur during the transshipment process. There was a problem such as a concern.

The present invention has been made to solve the above problems, the object of the present invention is usually buried underground, and when the means of transportation to reach the position to rise to the ground transport means for transporting the container It is to provide a ground lifter to support the container in the air lifted for reasons such as replacement.
