18-459: It was built in 1973–74 and could lift 1,500 tonnes (1,476 long tons ; 1,653 short tons ). The gauge of crane's rails was 174 metres (571 ft) and the rail length 710 metres (2,329 ft). The crane was used to build about 75 ships. Its last use in Malmö was in mid-1997, when it lifted the foundations of the high pillars of the Öresund Bridge . The crane was first sold in the early 1990s to

36-677: A ton typically refers to a short ton of 2,000 lb (907.2 kg) and to a lesser extent to a long ton of 2,240 lb (1,016 kg), with the term tonne rarely used in speech or writing. Both terms are acceptable in Canadian English . Ton and tonne are both derived from a Germanic word in general use in the North Sea area since the Middle Ages (cf. Old English and Old Frisian tunne , Old High German and Medieval Latin tunna , German and French tonne ) to designate

54-519: A large cask, or tun . A full tun, standing about a metre high, could easily weigh a tonne. See also the common German word de:Mülltonne (literal translation: garbage drum ). The spelling tonne pre-dates the introduction of the SI in 1960; it has been used with this meaning in France since 1842, when there were no metric prefixes for multiples of 10 and above, and is now used as the standard spelling for

72-582: A weight at one standard gravity of 2,000 pound-force (lbf) . In the United States , a short ton is usually known simply as a "ton", without distinguishing it from the tonne (1,000 kilograms or 2,204.62 pounds), known there as the "metric ton", or the long ton also known as the "imperial ton" (2,240 pounds or 1,016.05 kilograms). There are, however, some U.S. applications where unspecified tons normally mean long tons (for example, naval ships) or metric tons (world grain production figures). Both

90-453: Is a measurement unit equal to 2,000 pounds (907.18 kg). It is commonly used in the United States , where it is known simply as a ton; however, the term is ambiguous, the single word " ton " being variously used for short, long , and metric tons. The various tons are defined as units of mass. They are sometimes used as units of weight , the force exerted by a mass at standard gravity (e.g., short ton-force). One short ton exerts

108-481: Is a unit of mass equal to 1,000  kilograms . It is a non-SI unit accepted for use with SI . It is also referred to as a metric ton in the United States to distinguish it from the non-metric units of the short ton ( United States customary units ) and the long ton ( British imperial units ). It is equivalent to approximately 2,204.6 pounds , 1.102 short tons, and 0.984 long tons. The official SI unit

126-445: Is an established spelling alternative to metric ton . In the United States and United Kingdom, tonne is usually pronounced the same as ton ( / t ʌ n / ), but the final "e" can also be pronounced, i.e. " tunnie " ( / ˈ t ʌ n i / ). In Australia, the common and recommended pronunciation is / t ɒ n / . In the United States, metric ton is the name for this unit used and recommended by NIST; an unqualified mention of

144-438: Is little need to distinguish between metric and other tons, and the unit is spelled either as ton or tonne with the relevant prefix attached. A metric ton unit (mtu) can mean 10 kg (22 lb) within metal trading, particularly within the United States. It traditionally referred to a metric ton of ore containing 1% (i.e. 10 kg) of metal. The following excerpt from a mining geology textbook describes its usage in

162-424: Is significant, and use of other letter combinations can lead to ambiguity. For example, T, MT, mT, are the SI symbols for the tesla , megatesla, and millitesla, respectively, while Mt and mt are SI-compatible symbols for the megatonne (one teragram) and millitonne (one kilogram). If describing TNT equivalent units of energy, one megatonne of TNT is equivalent to approximately 4.184 petajoules . In English, tonne

180-400: Is the joule . One tonne of TNT is approximately equivalent to 4.2 gigajoules. In the petroleum industry the tonne of oil equivalent (toe) is a unit of energy : the amount of energy released by burning one tonne of crude oil , approximately 42 GJ. There are several slightly different definitions. This is ten times as much as a tonne of TNT because atmospheric oxygen is used. Like

198-509: Is the megagram ( Mg ), a less common way to express the same amount. The BIPM symbol for the tonne is t, adopted at the same time as the unit in 1879. Its use is also official for the metric ton in the United States, having been adopted by the United States National Institute of Standards and Technology (NIST). It is a symbol, not an abbreviation, and should not be followed by a period . Use of lower case

216-481: Is the mass of one cubic metre of pure water at 4 °C (39 °F). As a non-SI unit, the use of SI metric prefixes with the tonne does not fall within the SI standard. For multiples of the tonne, it is more usual to speak of thousands or millions of tonnes. Kilotonne, megatonne, and gigatonne are more usually used for the energy of nuclear explosions and other events in equivalent mass of TNT , often loosely as approximate figures. When used in this context, there

234-466: Is used as a proxy for energy, usually of explosions (TNT is a common high explosive ). Prefixes are used: kiloton(ne), megaton(ne), gigaton(ne), especially for expressing nuclear weapon yield , based on a specific combustion energy of TNT of about 4.2  MJ / kg (or one thermochemical calorie per milligram ). Hence, 1 t TNT = approx. 4.2  GJ , 1 kt TNT = approx. 4.2  TJ , 1 Mt TNT = approx. 4.2  PJ . The SI unit of energy

252-921: The Danish company Burmeister & Wain but the company went bankrupt before the crane could be moved. The crane was a landmark of Malmö from its time of construction until its dismantling in the summer of 2002, when it was shipped to Ulsan, after being sold to Hyundai Heavy Industries for $ 1. The Koreans have dubbed the crane 말뫼의 눈물 (Tears of Malmö), because the residents of Malmö reportedly wept when they saw their crane being towed away.

270-406: The gram and the kilogram, the tonne gave rise to a (now obsolete) force unit of the same name, the tonne-force, equivalent to about 9.8 kilonewtons . The unit is also often called simply "tonne" or "metric ton" without identifying it as a unit of force. In contrast to the tonne as a mass unit, the tonne-force is not accepted for use with SI. Short ton The short ton (abbreviation tn )

288-702: The crane is located on a tongue of land within the Bangeo-dong quarter right at the mouth of the Taehwa River . Additionally a second gantry crane with a lifting capacity of 1,600 tonnes (1,575 long tons ; 1,764 short tons ) was subsequently erected nearby. The two cranes share a common working area. "Tears of Malmö" is the more southern of the two. 55°36′52″N 12°59′23″E  /  55.6144615°N 12.9896602°E  / 55.6144615; 12.9896602 Tonne The tonne ( / t ʌ n / or / t ɒ n / ; symbol:  t )

306-522: The metric mass measurement in most English -speaking countries. In the United States, the unit was originally referred to using the French words millier or tonneau , but these terms are now obsolete. The British imperial and United States customary units are comparable to the tonne and the spelling of ton in English is the same, though they differ in mass. One tonne is equivalent to: A tonne

324-482: The particular case of tungsten: Tungsten concentrates are usually traded in metric tonne units (originally designating one tonne of ore containing 1% of WO 3 , today used to measure WO 3 quantities in 10 kg units. One metric tonne unit (mtu) of tungsten (VI) contains 7.93 kilograms of tungsten. In the case of uranium , MTU is sometimes used in the sense of metric ton of uranium (1,000 kg [2,200 lb]). The tonne of trinitrotoluene (TNT)
