Intermodal container
An intermodal container, often called a shipping container, or a freight container, (or simply "container") is a large metal crate designed and built for intermodal freight transport, meaning these containers can be used across different modes of transport – such as from ships to trains to trucks – without unloading and reloading their cargo. Intermodal containers are primarily used to store and transport materials and products efficiently and securely in the global containerized intermodal freight transport system, but smaller numbers are in regional use as well. It is like a boxcar that does not have wheels. Based on size alone, up to 95% of intermodal containers comply with ISO standards, and can officially be called ISO containers. These containers are known by many names: cargo container, sea container, ocean container, container van or sea van, sea can or C can, or MILVAN, or SEAVAN.[citation needed] The term CONEX (Box) is a technically incorrect carry-over usage of the name of an important predecessor of the ISO containers: the much smaller steel CONEX boxes used by the U.S. Army.
Intermodal containers exist in many types and standardized sizes, but 90 percent of the global container fleet are "dry freight" or "general purpose" containers: durable closed rectangular boxes, made of rust-retardant weathering steel; almost all 8 feet (2.4 m) wide, and of either 20 or 40 feet (6.1 or 12.2 m) standard length, as defined by International Organization for Standardization (ISO) standard 668:2020. The worldwide standard heights are 8 feet 6 inches (2.6 m) and 9 feet 6 inches (2.9 m) – the latter are known as High Cube or Hi-Cube (HC or HQ) containers. Depending on the source, these containers may be termed TEUs (twenty-foot equivalent units), reflecting the 20- or 40-foot dimensions.
Invented in the early 20th century, 40-foot intermodal containers proliferated during the 1960s and 1970s under the containerization innovations of the American shipping company SeaLand. Like cardboard boxes and pallets, these containers are a means to bundle cargo and goods into larger, unitized loads that can be easily handled, moved, and stacked, and that will pack tightly in a ship or yard. Intermodal containers share a number of construction features to withstand the stresses of intermodal shipping, to facilitate their handling, and to allow stacking. Each has a unique ISO 6346 reporting mark.
In 2012, there were about 20.5 million intermodal containers in the world of varying types to suit different cargoes. Containers have largely supplanted the traditional break bulk cargo; in 2010, containers accounted for 60% of the world's seaborne trade. The predominant alternative methods of transport carry bulk cargo, whether gaseous, liquid, or solid—e.g., by bulk carrier or tank ship, tank car, or truck. For air freight, the lighter weight IATA-defined unit load devices are used.
Containerization has its origins in early coal mining regions in England beginning in the late 18th century. In 1766 James Brindley designed the box boat 'Starvationer' with ten wooden containers, to transport coal from Worsley Delph (quarry) to Manchester by Bridgewater Canal. In 1795, Benjamin Outram opened the Little Eaton Gangway, upon which coal was carried in wagons built at his Butterley Ironwork. The horse-drawn wheeled wagons on the gangway took the form of containers, which, loaded with coal, could be transshipped from canal barges on the Derby Canal, which Outram had also promoted.
By the 1830s, railways were carrying containers that could be transferred to other modes of transport. The Liverpool and Manchester Railway in the UK was one of these, making use of "simple rectangular timber boxes" to convey coal from Lancashire collieries to Liverpool, where a crane transferred them to horse-drawn carriages. Originally used for moving coal on and off barges, "loose boxes" were used to containerize coal from the late 1780s, at places like the Bridgewater Canal. By the 1840s, iron boxes were in use as well as wooden ones. The early 1900s saw the adoption of closed container boxes designed for movement between road and rail.
The first international standard for containers was established by the Bureau International des Containers et du Transport Intermodal in 1933, and a second one in 1935, primarily for transport between European countries. American containers at this time were not standardized, and these early containers were not yet stackable – neither in the U.S. nor Europe. In November 1932, the first container terminal in the world was opened by the Pennsylvania Rail Road Company in Enola, Pennsylvania. Containerization was developed in Europe and the US as a way to revitalize rail companies after the Wall Street crash of 1929, in New York, which resulted in economic collapse and a drop in all modes of transport.
In April 1951 at Zürich Tiefenbrunnen railway station, the Swiss Museum of Transport and the Bureau International des Containers (BIC) held demonstrations of container systems for representatives from a number of European countries, and from the United States. A system was selected for Western Europe, based on the Netherlands' system for consumer goods and waste transportation called Laadkisten (lit. "Loading chests"), in use since 1934. This system used roller containers for transport by rail, truck and ship, in various configurations up to 12,100 pounds (5,500 kg) capacity, and up to 10 ft 2 in × 7 ft 6+1⁄2 in × 6 ft 6+3⁄4 in (3.1 m × 2.3 m × 2 m) in size. This became the first post World War II European railway standard of the International Union of Railways – UIC-590, known as "pa-Behälter". It was implemented in the Netherlands, Belgium, Luxembourg, West Germany, Switzerland, Sweden and Denmark.
