Rail-mounted Gantry Cranes

Rail-mounted gantry cranes (RMG) are specialized yard container handling machines.

An RMG travels on rails to lift and stack 20, 40 and other iso containers in the yard area of the container terminal. The container is lifted by a spreader attached to cables. Rail mounted cranes come in a variety of models with different spans and overhangs.

These cranes are specifically designed for intensive container stacking due to its automation and less need for human handling. Compared to the crane (RTG), the RMG has the advantages of being driven by electrical power, cleaner, bigger lifting capacity, and higher gantry traveling speed with cargo.

A container crane (also container handling gantry crane ) is a type of large dockside gantry crane found at container terminals for loading and unloading intermodal containers from container ship.
