793C Mining Truck
Engineered for performance, designed for comfort, built to last.Mechanical Power Train 4 Starting with the high torque rise, Caterpillar® 3516B, Electronic Unit Injection (EUI) diesel engine, through the electronic, six-speed power shift transmission, the mechanical power train is designed and built by Caterpillar, assuring the highest standards for quality, performance, efficiency and reduced operating costs. pg. 4-5

Engine Power Train Integration TheCaterpillar intelligent power train combines engine, transmission and brake information over the CAT Data Link to optimize overall truck performance. The CAT Data Link allows the engine and transmission to electronically exchange information so the components work together as a system for increased component life and improved operator comfort. The Electronic Technician (ET) software program can accessstored diagnostic data to significantly reduce downtime and improve troubleshooting. pg. 6-7

Oil-cooled Disc Brakes Caterpillar four-wheel forced oilcooled, multiple disc brakes are continuously cooled for exceptional, non-fade braking and retarding. The Integrated Braking Control (IBC) system integrates the Automatic Retarder Control (ARC) on all wheels and Traction Control System (TCS) on thedrive wheels into one system to enhance truck performance and productivity, and improve operator confidence. pg. 8

Total performance. The 793C is designed for high production, assuring lowest cost-per-ton hauling in mining applications. Reliable, durable operation. Rugged construction and easy maintenance guarantee extended life with low operating costs.

Operator’s Station The 793C operator’s station has been significantly improved over previous models by ergonomicallydesigning for total machine control in a comfortable and productive environment. All controls, levers, switches and gauges are positioned to maximize productivity and minimize operator fatigue. Electronic hoist control provides ease of operation. The integral ROPS structure provides superior operator protection. pg. 12

Vital Information Management System (VIMS) VIMS monitors vital machinesystems and functions. It helps coach the operator in the operation of the machine and alerts him to out of specification conditions. Down time is reduced by allowing service personnel to access machine data for faster, more accurate diagnosis. VIMS provides information to enhance equipment management, increase productivity and reduce cost per ton. pg. 13-14

Engine
The fieldproven 3516B EUI engine delivers the power and reliability necessary to perform in the world’s most demanding mining applications.

The Caterpillar Electronic Unit Injector (EUI) diesel engine is a four-stroke design that uses long, effective power strokes for more complete fuel combustion and optimum efficiency. The 3516B is a high displacement and low operating rpm engine, designed for extendedhours of service between scheduled overhauls and reduced operating costs. The 23 percent torque rise provides high lugging force during acceleration and less down shifting on grade or in soft underfooting for faster cycle times. Torque rise effectively matches the transmission shift points to maximize efficiency and yield higher performance. The 3516B engine provides unmatched combustion...
