Rubber tyred gantry crane

A rubber tyred gantry crane (RTG crane) (also transtainer) is a mobile gantry crane used for stacking intermodal containers within the stacking areas of a container terminal. RTGs are used at container terminals and container storage yards to straddle multiple lanes of rail/road and container storage, or when maximum storage density in the container stack is desired.^{[citation needed]}

A normal container crane runs on steel rails, instead of rubber-tyres. The side-view appearance of a RTG and a straddle carrier are fairly similar, but the top of a RTG also features a movable crane.

Different kind of RTGs

• The first electrified rubber-tyred gantry cranes (ERTG) in the United States was unveiled by The Georgia Ports Authority (GPA) in December 2012. The new technology reduces fuel consumption by an estimated 95 percent. The new ERTG system was developed with the help of Konecranes, Conductix-Wampfler and Georgia Power.
