PRODUCTIVITYThe Advanced Power Electronic Control Strategy (APECS) enables faster cycle times thanks to more continuous torque and rimpull.Forward momentum and torque are maintained through each shift, with optimum gear selection resulting in faster acceleration.The 789 delivers a 6% higher TKPH /TMPH (tonne-kilometer-per-hour / ton-mile-per-hour) thanks to larger tire options that allow allow mines to take advantage of higher speeds, particularly in flat, long-haul, high-speed applications.Productivity-enhancing features such as Hill Start Assist with Anti-Rollback, 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 and reducing operator fatigue.SAFETYWide, slip-resistant surfaces and hand rails, plus an optional powered access ladder, improve access and egress.Superior control is delivered by a patented braking system that provides immediate, fade-resistant braking and retarding.Visibility is enhanced by an optional 360-degree Surround View camera, which offers a bird’s-eye view.The 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.The optional Driver Safety System alerts the operator if fatigue or distraction are detected.OPERATOR COMFORTThe cab provides 34% more operator space than D-Series models. It’s 17% wider and offers 11% more legroom and 19% more shoulder room. Controls, levers and switches are positioned for ease of use.With 40% less Sound Pressure Level (SPL), automated temperature control and cab filtration, operators enjoy a safer and more comfortable environment.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, air adjustable side and lumbar bolsters, and heated and cooled cushions.Operators enjoy a more comfortable ride thanks to smoother transitional shifting and reduced shift jerk levels provided by APECS controls.OPERATOR EFFICIENCY & PRODUCTIVITYHigher resolution displays improve access to information. Machine data, controls and guidance information are consolidated onto two ideally located 10-inch screens.The optional Auto Hoist feature automatically raises the body and controls engine speed, simplifying operation and minimizing cycle times.Speed coaching gives operators real-time feedback on how to operate the truck to maximize its productivity.The payload monitoring system comes with more accurate measurements, providing immediate feedback to the operator.SERVICEABILITYThe new modular HVAC (heating, ventilation and air conditioning) system improves reliability and 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 provide immediate access to the latest software updates and make it possible to troubleshoot the machine remotely.Time spent on regular maintenance procedures is reduced thanks to features such as extended-interval filters with ground-level access; grouped service points and optional centralized service center; cleaner hydraulic and electrical routings; SOS and pressure ports for faster, safer oil sampling and troubleshooting; and fluid-level sight glasses.A 100% airless electric start option eliminates air system maintenance from the machine and improves uptime.DURABILITY AND LONG LIFELonger-life components, extended service intervals and easier maintenance deliver consistently high mechanical availability.A reduction in torque spikes and fewer variations in engine speed, made possible by APECS controls, deliver longer engine and powertrain component life.The 789 frame uses a box-section design, incorporating two forgings and 21 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.Component life is enhanced thanks to the standard rear-axle continuous filtration feature. Cleaner oil helps promote lubrication that leads to longer lifeThe frame, powertrain, engine and components are built to be rebuilt — delivering multiple lives of like-new performance at a fraction-of-new price.CAT BODIESCaterpillar designed and manufactured bodies are integrated with the chassis as a unit to optimize performance and incorporate optional Tier 4 components, including body exhaust heat.The lightweight Mine Specific Design (MSD) body is designed with built-in carryback reduction features (front wall curved transition and corner pop-out plates) and is available with optional application-specific body liners.Intended for tough applications, the heavy-duty Dual Slope body provides excellent load retention, maintains a low center of gravity with optimum load distribution and reduces shock loading.SUSTAINABILITYThe 789 is designed to use less fuel, which reduces engine emissions, and there is zero fuel burn during retarding. The Tier 4 Final engine reduces NOx and particulate matter.The Cat 3512E engine’s 12-cylinder four-stroke design uses long, effective power strokes for more complete fuel combustion and optimum fuel efficiency.The 789 engine is compatible with diesel fuel blended with lower-carbon intensity fuels such as biofuels and renewable fuels.Features like oil renewal systems, continuous rear axle filtration, extended life filters and longer maintenance intervals decrease the amount of waste contributed to the environment.By rebuilding machines and components, the Cat Rebuild and Cat Reman programs preserve raw materials, conserve energy and reduce emissions.VERSATILITYThe 789 is available in a cold-weather configuration that makes it ideal for mines operating in frigid environments. It features automatic engine thermal management, a variable fan speed for low temperature operation, and an electric- or air-start option.The 3512E engine gives you the ability to select the power rating to match your current fleet performance or to achieve faster cycle times.The 23% net torque rise provides unequaled lugging force during acceleration, on steep grades and in rough underfoot conditions.Tire options allow you to select the tire that best matches your application, with a larger tire for flat, long, high-speed applications. The frame is designed to maintain the same turning diameter while accommodating larger tires.The 789 is available in two options to meet emissions standards. The optional Tier 4 Final engine meets the strictest standards while the LRC engine is available in those countries that are less regulated.TECHNOLOGY SOLUTIONSMineStar Fleet is a fleet monitoring system that can be used to measure, manage and maximize the overall hauling operation.Additional MineStar Detect offerings include Awareness, which can provide warnings, and the in-cab Driver Safety System, which intervenes when it detects fatigue or distraction.Machine health and condition monitoring solutions enable a proactive approach to maintenance.BETTER TO ACCESS DATANext 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.Advanced connectivity on the 789 truck is enabled by standard cellular 4G/LTE, optional dual mode 4G/LTE and Satellite Product Link™, or locally installed Wi-Fi.Every machine from the factory comes with Product Link Elite as a standard offering.
