The Caterpillar
®
797, which features many patented innovations, was developed using a clean-
sheet approach. But the design also draws on the experience gained from hundreds of thousands
of operating hours accumulated by more than 35,000 Caterpillar construction and mining
trucks working worldwide. The 797 builds on such field-proven designs as the mechanical
power train, electronics that manage and monitor all systems, and structures that provide dura-
bility and long life. Engineers from various fields, including mechanical, electrical, structural,
hydraulic, and mining, collaborated to design the Caterpillar 797 mining truck.Caterpillar 797
