793D Mining Truck

The Cat® 793 Mining Truck was introduced more than three decades ago, and every model has continued to deliver excellent speed on grade, class-leading payload and long life — making it one of the most popular trucks in the mining industry. The 793D is no exception. The 793D delivers more power and performance for an increase in productivity, a class-leading empty weight that leads to optimized payload, and longer life for high operating hours, reduced costs and the opportunity to rebuild for multiple lives. The 793D is available in five configurations, making it the ideal choice for a wide variety of applications. It hauls more every load, every cycle and every shift. And it delivers a better bottom line to the most important mine in the world: yours.

PRODUCTIVITY

  • The Cat 3516E quad turbocharged and aftercooled diesel engine produces 2,415 hp with over 12% increase in life compared to the previous 3516B HD engine, and enhanced power management capability for maximum hauling performance in the most demanding mining applications.
  • The 23% net torque rise provides unequaled lugging force during acceleration, on steep grades and in rough underfoot conditions. Torque rise effectively matches transmission shift points for maximum efficiency and fast cycle times.
  • 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
  • The 793D has an empty machine weight advantage over competitive machines. It hauls more with every load while improving tire life, and reducing fuel burn and delivering faster cycle times during return hauls.
  • Common rail hydraulics deliver up to 4% additional power to the ground rather than to functions that are not needed at the time.

SAFETY

  • Access and egress are safer thanks to the 600-mm-wide (24-in-wide) stairway and walkways, slip-resistant surfaces and hand rails, plus optional powered access stairway. An optional rear cab access platform and handrail provide enhanced access to cab service panel and rear window.
  • Superior control is delivered by a patented braking system that provides immediate, fade-resistant braking and retarding.
  • The 793D is designed for excellent all-around visibility and clear sight lines, enhanced by wide-angle mirrors and the standard Cat MineStar™ Object Detection system, combines radar and camera systems to warn operators about light vehicles or stationary hazards within the immediate vicinity of their machines.
  • Dumping operations are safer thanks to a body raised indicator, body retaining cable and reverse neutralizer when dumping.
  • A secondary engine shutoff switch is located at ground level, and a battery disconnect switch is located directly above the front bumper, providing ground-level lockout of the electrical system.

OPERATOR COMFORT

  • Operators enjoy an ergonomic layout, excellent all-around visibility, and controls, levers, switches and gauges that are positioned for ease of use.
  • The cab has numerous features that enhance comfort and reduce fatigue, such as an air suspension seat, reduced vibration, heating and air conditioning, and sound suppression.
  • Caterpillar designed integrated steering and suspension deliver excellent maneuverability, safe operation, lower operating costs,
  • and a comfortable ride.
  • The 793D comes standard with the Cat Comfort Seat with 3-point harness, which can be adjusted for proper height over the operator’s left shoulder. The unique ride zone indicator feature allows the air suspension to compensate for the operator’s weight and keeps the seat adjusted for the most comfortable positioning and ride.

SERVICEABILITY

  • Time spent on regular maintenance procedures is reduced with easy access to daily service points and major components; ground-level access to tanks, filters, drains and engine shutdown; a maintenance platform that provides access to the engine engine, steering hydraulic tank and battery compartment; and an optional fast-fill service center, which enables high-speed fuel and oil exchange.
  • The modular design of the new generation modular radiator reduces removal & installation time because the stairway, cowling, radiator, fan and fan motor remove together as a single unit.
  • Enhanced serviceability and 500-hour service intervals are designed to increase machine availability and productivity.
  • Electric connectors are sealed to lock out dust and moisture, harnesses are braided for protection, and wires are color- coded for easy diagnosis and repair.
  • Individual cylinder heads are interchangeable for easy removal and visual inspection of internal parts.

DURABILITY AND LONG LIFE

  • The 793D frame uses a box-section design, incorporating two forgings and 24 castings in high-stress areas with deep penetrating and continuous wrap-around welds to resist damage from twisting loads without adding extra weight. The mild steel frame provides flexibility, durability and resistance to impact loads.
  • Resiliently mounted to the main frame to reduce vibration and sound, the integral ROPS is designed as an extension of the truck frame.
  • Component life is enhanced thanks to the standard rear-axle continuous filtration feature. Cleaner oil helps promote lubrication that leads to longer life.
  • The frame, powertrain, engine and components are built to be rebuilt — delivering multiple lives of like-new performance at a fraction-of-new price.

CAT BODIES

  • Cat bodies are the best choice for the 793D. They’re designed to be an integral part of the entire vehicle system, ensuring you achieve maximum chassis life.
  • The High Performance (HP) body features a lightweight, simplified and durable design that provides complete front machine coverage and extended overhead protection.
  • Available in several sizes, the MSD II body is ideal for mature mines with good operational and maintenance practices. It can be lined or unlined, with a site-specific body designed to maximize performance.
  • Intended for tough applications including greenfield sites and contracting mines, the Dual Slope body provides excellent load retention, maintains a low center of gravity with optimum load distribution and reduces shock loading.
  • The specialty combination body for coal and coal overburden accommodates light density material while maintaining payload potential.

SUSTAINABILITY

  • We’ve designed the 793D with a number of enhancements that lessen its impact on the environment. Features like oil renewal systems and continuous rear axle filtration decrease the amount of waste contributed to the environment.
  • We continue to research alternative energy sources such as biofuels and a liquefied natural gas-supplied Dynamic Gas Blending solution, and we’re implementing power options like electrification and trolley to find new ways to reduce emissions.
  • Cat engines are compatible with diesel fuel blended with lower-carbon intensity fuels such as biodiesel FAME (fatty acid methyl ester). They are also compatible with renewable fuels such as HVO (Hydrotreated Vegetable Oil) and GTL (Gasto-Liquid) alternative fuels that are drop-in replacements for diesel. HVO and GTL are acceptable for use in all Cat engines at any blend level and up to 100%.
  • By rebuilding machines and components, the Cat Rebuild and Cat Reman programs preserve raw materials, conserve energy and reduce emissions.

VERSATILITY

  • The 793D is available in five merchandising arrangements to meet your application needs: Standard, for balanced all-around performance; Extended Life Wheel Groups for long, uphill hauls; Extra Top Speed for long, flat hauls; Extra Retarding for long, downhill loaded hauls; and High Altitude Arrangement for operations above 2750 m (9,000 ft)
  • The Cat Dynamic Gas Blending™ (DGB™) Retrofit Kit allows the 793D to use both liquefied natural gas and diesel fuel for operation in areas where LNG is readily available.
  • The mechanical drive powertrain and power shift transmission provide unmatched efficiency and control on steep grades, in poor underfoot conditions and on haul roads with high rolling resistance.

TECHNOLOGY SOLUTIONS

  • MineStar Command for hauling, an autonomous hauling solution proven to increase productivity up to 30%, is offered as a retrofit kit for the 793D.
  • MineStar Fleet is a fleet monitoring system that can be used to measure, manage and maximize the overall hauling operation.
  • The MineStar Detect in-cab Driver Safety System intervenes when it detects fatigue or distraction
  • Machine health and condition monitoring solutions enable a proactive approach to maintenance.
