Currently, maritime trade volume is increasing due to inter-country trade or inter-regional cargo transportation, and container-based logistics transportation is continuously increasing by such transportation or trade.

In general, the way of transporting containers is divided into land transportation and maritime transportation, while land transportation is divided into transportation through merit and transportation through rail. At present, the merit is in a saturated state, and effort and research are actively carried out to increase the amount of transportation through the railway due to accidents caused by long-time operation of the trailer and environmental pollution caused by soot. In this way, transportation through the railway is cheap and reliable, but there is a disadvantage that the connection area with the railway is limited. Also, in order to transport a container using a railroad, there is a problem that it is difficult or impossible to carry out direct delivery (door to door) and real-time delivery (JIT (Just in time)) because containers must be stored in a loading or docking station.

On the other hand, in the current iron bill, most of the cranes are used for loading / unloading containers between the trailer and the freight car. However, since the electric wires are installed in the work place due to the transfer of the locomotive, The development of the method is urgently required.
