TECHNOLOGY SOLUTIONS
- The 793 is faster than competitive trucks and delivers optimal speed on steep grades, poor underfoot conditions and haul roads with high rolling resistance. More continuous torque and rimpull delivers more power to the ground and makes it possible to use a higher gear on grade.
- Forward momentum and torque are maintained through each shift, with optimum gear selection resulting in faster acceleration.
- The Cat six-speed transmission, with the latest Advanced Power Electronic Control Strategy (APECS) controls, is paired with the C175-16 engine to deliver optimum power over a wide range of operating speeds.
- An empty weight advantage of 13-19 tonnes (14-21 tons) over competitive electric drive trucks in its size class ensures you’re getting the full payload you expect.
- Features such as Enhanced Traction Control, Dynamic Stability Control (DSC), Anti-lock Brake System (ABS), Machine Speed Limiting and Cruise Control improve machine responsiveness and controllability while improving cycle times.
- Access and egress are improved by wide walkways, ladders, catwalks and service platforms; slip-resistant surfaces and guard rails; plus a wide secondary egress ladder and a rear service access ladder.
- Superior control is delivered by a patented braking system that provides immediate, fade-resistant braking and retarding.
- A 360 Surround View camera system gives the operator greater visibility to the ground around the truck. In addition, the standard Cat MineStar™ Detect Object Detection system combines radar and camera systems to warn operators about hazards within the immediate vicinity.
- The optional Driver Safety System alerts the operator if fatigue or distraction are detected.
- The cab can be equipped with High Efficiency Particulate Air (HEPA) filters to cut respirable dust penetration by 96% — reducing operator exposure to potentially hazardous substances.
- The cab provides 34% more operator space than D-Series models. It’s 17% wider, offers 11% more legroom and 19% more shoulder room.
- The cab is quieter and offers automated temperature control and cab filtration for a safer and more comfortable environment.
- Controls, levers and switches are positioned for ease of use.
- A walkthrough cab with fully adjustable center console, easy-to-adjust seat and increased leg room makes the cab ideal for operators of all sizes.
- The next generation seat is four-point-restraint ready and incorporates features like thigh tilt and extensions, 30% recline, air adjustable side and lumbar bolsters, and heated and cooled cushions.
- The optional Auto Hoist feature automatically raises the body and controls engine speed, minimizing cycle times.
- Speed coaching gives operators real-time feedback on how to operate the truck to maximize its productivity, and advanced speed controls allow the operator to quickly and easily set a desired machine speed and control it on-the-fly.
- The payload monitoring system comes with more accurate measurements, improved monitoring and an improved interface.
- Operator identification provides seamless integration of operator preference, with custom settings stored and restored to the saved settings upon log-in.
- Faster data transfers and higher resolution displays improve access to information. Machine data, controls and guidance information are consolidated onto two 10-inch screens.
- The new modular HVAC system consolidates components so the entire system can be removed and replaced quickly.
- A modular radiator reduces engine removal and installation time and enables rebuilds to be completed off the truck.
- New remote flash and remote troubleshooting capabilities reduce machine downtime due to software up to 50%.
- Time spent on regular maintenance procedures is reduced thanks to features such as extended service intervals; grouped ground-level maintenance and checkpoints; easy access to major components; the standard AutoLube system; and service platforms on the engine and transmission.
- A 100% airless electric start option eliminates air system maintenance from the machine and improves uptime.
- The 793 has been improved with longer-life components, extended service intervals and easier maintenance to deliver mechanical availability that is consistently greater than 90%.
- The 793 is built on the durable 240-tonne (266-ton) frame, backed by unprecedented levels of virtual and in-iron validation.
- A mild steel frame provides flexibility, durability and resistance to impact loads. Castings are used in high-stress areas and the integral 4-post ROPS cab provides increased strength.
- Component life is enhanced thanks to the standard rear-axle continuous filtration feature. Cleaner oil helps promote longer 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 are the best choice for the 793. They’re designed to be an integral part of the entire vehicle system, ensuring you achieve maximum chassis life.
- The Max Payload (MP) body is a lightweight, bolster-less design utilizing formed base plates in place of traditional structural members. It employs a convex canopy and a strong perimeter reinforcement in the top rail and rear rib.
- The High Performance (HP) body features a lightweight, simplified and durable design that provides complete front machine coverage and extended overhead protection.
- The 793 can be configured with our traditional body options, which are also specifically designed to work with the Cat frame for superior structural performance.
- The 793 is designed to use less fuel, which reduces engine emissions, and there is zero fuel burn during retarding. The optional Tier 4 Final engine reduces NOx and particulate matter.
- Features like rear axle filtration, extended life filters and longer maintenance intervals decrease the amount of waste contributed to the environment.
- Features such as the Centrifugal Oil Filter (COF) and Self-Cleaning Filter (SCF), combined with S•O•S Services, maximize the life of engine oil and minimize environmental impact.
- The 793 engine is compatible with diesel fuel blended with lower-carbon intensity fuels such as biofuels and renewable fuels.
- By rebuilding machines and components, the Cat Rebuild and Cat Reman programs preserve raw materials, conserve energy and reduce emissions.
- Next generation connectivity delivers faster data transfers, better access to data, consistent data communication, more actionable data, improved data analytics and new diagnostic capabilities.
- The backbone of the next generation machine is 100 Mbps two-wire ethernet communication across the machine controllers, sensors that are optimized for data analytics, and robust controls.
- Every machine from the factory comes standard with Product Link™ cellular connectivity as well as an option to communicate through dual-mode cellular 4G/LTE and satellite, or local Wi-Fi networks.
- Product Link Elite next generation hardware enables the truck to collect and transmit information into locally-hosted or cloud-hosted applications. The hardware delivers fast processing with enhanced onboard memory and storage capability.
- Designed for future updates, the 793 features an expandable platform and architecture and leaves the factory ready for full integration of standard and optional technologies.
- MineStar Fleet is a fleet monitoring system that can be used to measure, manage and maximize the overall hauling operation.
- MineStar Command for hauling, an autonomous hauling solution proven to increase productivity up to 30%, is a fully integrated factory offering.
- Machine health solutions such as Equipment Care Advisor, Health Equipment Insights and Health Office enable a proactive approach to maintenance.
