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, and positioning pipelines.

Diesel fuel, also called diesel oil or historically heavy oil, is any liquid fuel specifically designed for use in a diesel engine, a type of internal combustion engine in which fuel ignition takes place without a spark as a result of compression of the inlet air and then injection of fuel. Therefore, diesel fuel needs good compression ignition characteristics.

A radioisotope thermoelectric generator, sometimes referred to as a radioisotope power system (RPS), is a type of nuclear battery that uses an array of thermocouples to convert the heat released by the decay of a suitable radioactive material into electricity by the Seebeck effect. This type of generator has no moving parts. Because they don't need solar energy, RTGs are ideal for remote and harsh environments for extended periods, and because they have no moving parts, there is no risk of parts wearing out or malfunctioning.

<span class="mw-page-title-main">Crane (machine)</span> Type of machine

A crane is a type of machine, generally equipped with a hoist rope, wire ropes or chains, and sheaves, that can be used both to lift and lower materials and to move them horizontally. It is mainly used for lifting heavy objects and transporting them to other places. The device uses one or more simple machines to create mechanical advantage and thus move loads beyond the normal capability of a human. 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.

<span class="mw-page-title-main">Intermodal freight transport</span> Cargo transport using multiple containers

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.

<span class="mw-page-title-main">Railway electrification</span> Conversion of railways to use electricity for propulsion

Railway electrification is the use of electric power for the propulsion of rail transport. Electric railways use either electric locomotives, electric multiple units or both. Electricity is typically generated in large and relatively efficient generating stations, transmitted to the railway network and distributed to the trains. Some electric railways have their own dedicated generating stations and transmission lines, but most purchase power from an electric utility. The railway usually provides its own distribution lines, switches, and transformers.

A cargo ship or freighter is a merchant ship that carries cargo, goods, and materials from one port to another. Thousands of cargo carriers ply the world's seas and oceans each year, handling the bulk of international trade. Cargo ships are usually specially designed for the task, often being equipped with cranes and other mechanisms to load and unload, and come in all sizes. Today, they are almost always built of welded steel, and with some exceptions generally have a life expectancy of 25 to 30 years before being scrapped.

A fuel tank is a safe container for flammable fluids, often gasoline or diesel fuel. Though any storage tank for fuel may be so called, the term is typically applied to part of an engine system in which the fuel is stored and propelled or released into an engine. Fuel tanks range in size and complexity from the small plastic tank of a butane lighter to the multi-chambered cryogenic Space Shuttle external tank.

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.
