Excerpt: The Caterpillar 797 is a series of off-highway, ultra class, two-axle, mechanical powertrain haul trucks developed and manufactured in the United States by Caterpillar Inc. specifically for high-production mining and heavy-duty construction applications world-wide. In production since 1998, the 797 series represents Caterpillar's largest, highest capacity haul trucks. The current, third-generation model, the 797F, offers one of the largest haul truck payload capacities in the world, up to 400 short tons (363 t) and is the world's largest, highest payload capacity, mechanical drive haul truck. In 1997, Caterpillar decided to begin development of a 360 short tons (327 t) payload capacity haul truck to meet the demand from large-scale mine operators wanting to reduce operating costs at mines using 80 to 90 short tons (73 to 82 t) per pass shovels. Engineers at Caterpillar's Mining & Construction Equipment Division in Decatur, Illinois, created a new design for the 797 using computer-aided design technology. This was the first time CAD tools had been used extensively to design a Caterpillar truck. Caterpillar first unveiled a completed 797 on September 29, 1998, at its assembly plant in Decatur, Illinois. The first two 797s produced were transported to Caterpillar's Arizona proving grounds for testing. In the second quarter of 1999, the third and fourth 797s produced were the first to be placed in service with a customer at the Bingham Canyon Mine in Utah. Caterpillar put 18 additional 797s into service with mine operators world-wide as production development units. Caterpillar began marketing the 797 in North America in 2000, with full world-wide marketing following in 2001. Caterpillar introduced the 797B in spring of 2002, replacing the first-generation 797. Caterpillar increased the power output of the Cat 3524B engine to cope with the 797B's higher payload capacity of up to 380 short tons (345 t), a 20 short tons (18 t) improvement over the 797.
