A container crane (also container handling gantry crane or ship-to-shore crane) is a type of large dockside gantry crane found at container terminals for loading and unloading intermodal containers from container ships. Container cranes consist of a supporting framework that can traverse the length of a quay or yard on a rail track. Instead of a hook, they are equipped with a specialized handling tool called a spreader.
A ship-to-shore container crane that is able to load and unload vessels that are up to 25 container rows wide and lift to a height of 46 metres.
RTG is especially used to pile containers, with the character of flexibility. RTG (Rubber Tyred Gantry Cranes) can be used to file container in the docts, at inland transits and at railway container yards. Up to now, RTG’s theoretical work effiency would be 30 to 40 containers per hour.
