Power Train - Engine

The Cat 3516B High Displacement engine is built for power, reliability and efficiency for superior performance in the toughest applications. The field-proven engine delivers high horsepower, superior fuel efficiency, lower emissions, reduced engine noise and lower operating costs.

Power Train - Merchandising Arrangements

The 793D is available in four different normal altitude configurations and one arrangement for high altitude operations. All configurations include key components matched to performance requirements in specific applications and conditions.

Power Train - Transmission

The Cat six-speed power shift transmission and mechanical power train, matched with the electronic unit injection 3516B high displacement engine, provides consistent power and efficiency for peak power train performance.

Engine/Power Train Integration

The Cat Data Link electronically combines engine, transmission, brake and operational information to optimize overall truck performance. Stored diagnostic data can be accessed via the Electronic Technician (Cat ET) to improve troubleshooting and reduce downtime.

Caterpillar Brake System

Cat oil-cooled, multiple disc brakes offer exceptional, fade-resistant braking and retarding for maximum performance and productivity in all haul road conditions. Integrated Braking Control combines retarding and traction control into one system for optimum braking efficiency.


Caterpillar truck frames are built to optimize torsional load displacement. Mild steel provides flexibility, durability and resistance to impact loads. Castings and forgings in high stress areas provide exceptional strength and durability for long life.

Monitoring System

The VIMS™ monitoring system provides operators, service technicians and mine personnel with vital machine health and payload data to keep the 793D performing at peak efficiency and top production levels while lowering cost-per-ton.

Truck Body Systems

A variety of Caterpillar designed and built truck bodies ensure optimal performance and reliability in tough mining applications. Cat dealers can help build an optimum hauling system to maximize truck payloads and extend body and truck wear life.

Customer Support

Caterpillar dealers provide unmatched product support, anywhere in the world. With the best part availability in the world and a wide range of maintenance and service options, Cat dealers have what it takes to keep your mining machine productive.

Operator's Station

The ergonomic cab is designed for operator comfort and ease of operation to allow the operator to focus on production. Controls and gauges are positioned within easy reach for optimum efficiency and superior control.


The 793D is designed for quick and easy servicing. Simplified service and maintenance features reduce downtime, allowing the machine to spend less time being serviced and more time on the haul roads.


Caterpillar sets the standard when it comes to safety in the design and manufacturing of heavy equipment for the mining industry. Safety is not an afterthought at Caterpillar, but an integral part of all machine and systems designs.
