- Terex Titan
The Terex Titan 33-19 was a prototype off-road earth hauler built by the Terex Division of
General Motors Corporation . It was first shown to the public in Las Vegas at theAmerican Mining Congress . Built in General Motors'London, Ontario ,Canada plant, the 33-19 was the largest in the Terex 33 series of off-road haulers, others being the 33-03, 33-05, 33-07, 33-09, 33-11 and the 33-15. It had an operating capacity of 320ton s, an empty weight of 235, and a maximum loaded weight of 553. At the time of its construction, it was the largest truck ever built, but the size record was broken by theCaterpillar 797B in 1998.Characteristics
The Titan was powered by a 10,343 cid, 16-cylinder 3300/3000 hp
locomotive engine coupled to a EMD AR10-D14 generator. This Electro-Motive Division engine, as the 16-645E4 prime mover, was aftercooled and turbocharged. The generator then powered 4 electrictraction motor s located at each rear wheel. The Terex featured large 40.00x57tire s made of rubber. It is 66 feet (20 m) long and 22.6 feet (6.9 m) tall; or 56 feet (17.1 m) tall with the dump body raised.History
Terex assembled the Titan for
Kaiser Steel in its Eagle Mountain iron mine in late 1974. At this mine the Titan suffered fromdowntime problems but eventually hauled some three-and-a-half million tons of earth until 1978.In late 1978 it was then brought to Kaiser Steel's Sparwood mine in
Canada . In 1980 the mine changed hands as B.C. Resources acquired all of the Kaiser property, and was renamedB.C. Coal . In 1983 the mine was again renamed, toWestar Mining , and the Titan also changed colors from lime green to Westar's blue and yellow. Shortly after, Westar directly purchased the Titan from General Motors, for US$200 thousand and $1 million in spare parts. In the following six years the Titan had a uptime rate of over 70% as it hauled loads of over 360 tons during this time. Westar finally retired the Titan in 1991.Public display
Teck Corporation bought the Sparwood mine in late 1992 and offered it for preservation as a public monument in 1993; the Sparwood Chamber of Commerence subsequently established a fundraising effort for the restoration of the Titan. It currently sits on Highway 3 in Sparwood as a public display and Sparwood promotes it as a tourist attraction [ [http://www.sparwood.bc.ca/titaninf.htm "The TEREX TITAN"] , retrieved 14 June 2008.] . The engine has since been removed.Other earth-haulers
Wabco also built the 3200/3200B during the 1970s, another 3-axle hauler, which was smaller than the Titan but similar-looking.The modern
Liebherr T 282B truck has slightly smaller dimensions and smaller empty weight, but larger load capacity and a more powerful engine. Unlike the Titan, it is a commercially available model, rather than a prototype.References
