The Terex 33-19 "Titan" is a prototype off-highway, ultra class, rigid frame, three-axle, diesel/AC electric powertrain haul truck designed and built by the Terex Division of General Motors in 1973.[1] Only one 33-19 was ever produced. After 13 years in service, the 33-19 was restored and is now preserved on static display in Sparwood, BC, Canada
Public Debut
The 33-19 "Titan" was first shown to the public in October, 1974 at the American Mining Congress in Las Vegas, NV.[2] The 33-19 "Titan" was the largest in the Terex 33 series of off-road haulers, which also included the 33-03, 33-05, 33-07, 33-09, 33-11 and the 33-15.
Development
General Motors developed the 33-19 "Titan" in response to open pit mine operators need for more efficient haul trucks and because GM believed that a general decrease in mineral ore quality combined with an projected need to mine oil shale and tar sands would increase the quantity of ore hauled by mine operators world wide.[3]
Assemby
The 33-19 "Titan" was assembled at the GM Diesel Division's London, Ontario, Canada assembly plant.[4]
Powertrain
The 33-19 "Titan" was powered by an Electro-Motive Division model 16-645E4, 16-cylinder, gross 3,300 hp (2,461 kW), 10,320 cubic inches (169.1 L), intercooled and turbocharged locomotive engine prime mover directly coupled to an Electro-Motive Division model AR10-D14, 10-pole, AC electric alternator sending DC power via a rectifier to General Motors model D79CF traction motors at each of the four rear wheels.
Specifications
The 33-19 "Titan" has a payload capacity of 350 short tons (320 t), a net vehicle weight of 509,500 pounds (231,100 kg) and a gross vehicle weight of 1,209,500 pounds (548,600 kg). At the time of its construction in 1973, the 33-19 was the largest, highest payload capacity truck ever built.[5] The 33-19 "Titan" remained the highest capacity haul truck in existence until the September, 1998 debut of the 360 short tons (330 t) payload capacity Caterpillar 797 .[6]
Fully loaded, the 33-19 "Titan" has a top speed of 29.8 mph (48.0 km/h)
The 33-19 required ten 40.00x57 tires.[5]
Service History
Terex placed the 33-19 "Titan" into service with Kaiser Steel at the Eagle Mountain, CA iron mine in late 1974. The 33-19 "Titan" suffered frequent downtime problems but over the course of its four years of service at the Eagle Mountain mine, the 33-19 "Titan" hauled approximately 3.5 million tons of earth.
In late 1978 the 33-19 "Titan" was sent to Kaiser Steel's Sparwood Canada mine. The mine was acquired from Kaiser Steel by B.C. Resources in 1980. The mine was subsequently acquired by Westar Mining in 1983 and the 33-19 "Titan" was repainted from its original lime green to Westar Mining's blue and yellow livery. Shortly after, Westar Mining directly purchased the 33-19 "Titan" from General Motors, for US $200,000 and $1 million in spare parts. During Westar Mining's ownership, the 33-19 "Titan" had an uptime rate of more than 70%, regularly hauling loads exceeding 350 short tons (320 t). Westar Mining retired the 33-19 "Titan" from service in 1991.
Public Display
After acquiring the Sparwood mine in late 1992, Teck Corporation offered the 33-19 "Titan" for preservation as a public monument in 1993. The Sparwood, BC Chamber of Commerce completed a fund raising effort for the restoration of the 33-19 "Titan". The 33-19 "Titan" is now promoted as a tourist attraction and is currently on static display on Highway 3 in Sparwood, BC. [7] Although the 33-19 "Titan" was restored, the engine has been removed.
