20ft / 40ft Container Lifting RTG Gantry Crane 40t 50t With Telescopic Spreader

A container crane is a large quayside gantry crane found in container terminals for loading and unloading intermodal containers from container ships. Container cranes consist of a support frame that can run the length of a quay or yard on rail tracks. Instead of hooks, they come with specialized handling tools called spreaders. The spreader can be lowered onto the top of the container and locks onto the container at four locking points using a twist lock mechanism. Cranes typically transport one container at a time, but some newer cranes are capable of picking up two to four 20-foot containers at a time.

The crane is driven by an operator sitting in a cab on the crane. The trolley runs along rails located on top or on the side of the boom and girder. Operators place trolleys on board to lift cargo, usually containers. Once the spreader is locked onto the container, the container is lifted, moved across the dock, and placed on a truck chassis (trailer) for delivery to the yard. The crane also lifts the container from the dock's chassis to load it onto the ship. A straddle carrier, side lift, reach stacker or container truck maneuvers under the crane base and collects the container, moving it quickly from the dock to the storage yard. Flatbed or well trucks can also be loaded directly under the crane base.
