The Terex Titan where it currently stands in Sparwood, B.C.

In his book "Euclid and Terex Earthmoving Machines" Eric Orlemannn has Chapter 6 on the 33-19 from pages 92-103. The Terex Titan 33-19 was a large 350 ton off-highway hauler built by the Terex Division of General Motor.It was first shown to the public in Las Vegas at the AMC American MIning Congress.It was built in GMs London,Ontario,Canada plant.It was the largest in the Terex 33 Series of off-highway haulers.Others were the 33-03,33-05,33-07,33-09,33-11 and the 33-15 It had an empty weight of 235 tons, and a maximum loaded weight of 1,220,400lbs; at the time of its construction, it was the largest truck ever built.The 33-19 was the second largest off-highway hauler in the 20th Century behind the Caterpillar 797. It was powered by a 10,343 cid 16 cylinder 3300/3000hp locomotive engine coupled to a EMD AR10-D14 generator.This Electro-Motive Division engine as the 16-645E4 prime mover which was aftercooled and turbocharged. The generator then powered 4 electric traction motors located at each rear wheel. The 33-19 featured the large 40.00x57 tire which Terex used for rubber.It is 66 feet (20 m) long and 22.6 feet (6.9 m) tall. It is 56 feet (17.1 m) tall with the dump body raised.Terex shipped the 33-19 to Kasier Steel's Eagle Monutain mine in southern Californina very late in 1974.At this mine the 33-19 hauler 3 and 1/2 million tons of earth despite it being down alot. In late 1978 it shipped to Kaiser's Resources Sparwood,B.C. mine.In 1980 the mine changed hands as B.C.Resources acquired all of the Kaiser property. The Sparwod mine was renamed B.C Coal LTD.In 1983 the name was changed to Westar Mining,LTD.The truck also changed colors from lime green to Westar's blue and yellow.Shortly after Westar purchased the 33-19 from General Motors for 200 thousand and $1 million in spare parts.For a period of six years the 33-19 had a uptime rate of over 70% as it hauled loads over 800,000 pounds during this time.Westar retired the Terex 33-19 Titan in 1991.Teck Corporation in late 1992 bought the mine the this big hauler worked in and came to the realization that its days were numbered.In the mean one year later in 1993 the company offered Sparwood for preservation as a monumentIt was during this time in 1993 that the Sparwood Chamber of Commerence established a fundraising effort for the restoration of this big off-highway hauler.It currently sits on Route 3 in Sparwood for all passerbys to see.. The engine has since been removed.Wabco also built the 3200/3200B during the 1970s which was also 3 axle hauler like the 33-19 which was smaller but similar in looks.

The modern Liebherr T 282B truck has slightly smaller dimensions and smaller empty mass, but larger load capacity and a more powerful engine. Unlike the Titan, it is a normal, commercially available model, rather than a prototype.
