A rubber tyred gantry crane (US: rubber tired gantry crane)/ RTG (crane), or sometimes transtainer, is a wheeled mobile gantry crane operated to ground or stack intermodal containers. Inbound containers are stored for future pickup by drayage trucks, and outbound are stored for future loading onto vessels. RTGs typically straddle multiple lanes, with one lane reserved for container transfers. [1] Advantages:its mobility gives a rubber tyred gantry crane wide appliance
Being mobile, RTGs are often powered by diesel generator systems (gensets) of 100 to 600 kW (134 to 805 hp). Due to the lack of an electrical grid to dump energy when containers are being lowered they often have large resistor packs to rapidly dissipate the energy of a lowering or decelerating container. [2] Diesel-powered RTGs are notorious polluters at ports, as each burns up to 10 US gallons per hour (8.3 imp gal/h ; 38 L/h ) of diesel fuel. [3]
There are also electric rubber tired gantry cranes. [4] The first electrified rubber-tyred gantry cranes (ERTG) in China was unveiled by the She Kou container terminal (SCT) in Shenzhen in Aug 2008. Rubber-tired gantry cranes are also being electrified at the Port of Long Beach to improve air quality, with funding from the California Energy Commission. [3]
Aside from the intermodal industry, RTGs also are extensively used in industry. Applications include erecting large unbalanced structures, assembling large manufacturing components, positioning pipelines, and bridge construction.
Some RTGs use automation technology at ports to reduce human involvement in processing and handling cargo. Automation technology is used to optimize, track, or communicate container movements (e.g., automated gate systems), as well as automated cargo handling equipment to load, unload, and move containers.

A port is a maritime facility comprising one or more wharves or loading areas, where ships load and discharge cargo and passengers. Although usually situated on a sea coast or estuary, ports can also be found far inland, such as Hamburg, Manchester and Duluth; these access the sea via rivers or canals. Because of their roles as ports of entry for immigrants as well as soldiers in wartime, many port cities have experienced dramatic multi-ethnic and multicultural changes throughout their histories.
A crane is a machine used to move materials both vertically and horizontally, utilizing a system of a boom, hoist, wire ropes or chains, and sheaves for lifting and relocating heavy objects within the swing of its boom. The device uses one or more simple machines, such as the lever and pulley, to create mechanical advantage to do its work. Cranes are commonly employed in transportation for the loading and unloading of freight, in construction for the movement of materials, and in manufacturing for the assembling of heavy equipment.
Intermodal freight transport involves the transportation of freight in an intermodal container or vehicle, using multiple modes of transportation, without any handling of the freight itself when changing modes. The method reduces cargo handling, and so improves security, reduces damage and loss, and allows freight to be transported faster. Reduced costs over road trucking is the key benefit for inter-continental use. This may be offset by reduced timings for road transport over shorter distances.
A sidelifter is a specialised vehicle or semi-trailer used to hoist and transport ISO standard intermodal containers over longer distances.
A container crane is a type of large dockside gantry crane found at container terminals for loading and unloading intermodal containers from container ships.
Rail freight transport is the use of railways and trains to transport cargo as opposed to human passengers.
Belfast Harbour is a major maritime hub in Belfast, Northern Ireland, handling 67% of Northern Ireland's seaborne trade and about 25% of the maritime trade of the entire island of Ireland. It is a vital gateway for raw materials, exports and consumer goods, and is also Northern Ireland's leading logistics and distribution hub.
A gantry crane is a crane built atop a gantry, which is a structure used to straddle an object or workspace. They can range from enormous "full" gantry cranes, capable of lifting some of the heaviest loads in the world, to small shop cranes, used for tasks such as lifting automobile engines out of vehicles. They are also called portal cranes, the "portal" being the empty space straddled by the gantry.
