Sustainability
MINING — FOR A — BETTER WORLD
Governments and regulatory agencies mandate that you establish and follow environmentally sound policies and practices as you meet the demand for mined materials. We’re focused on doing our part to make sure our trucks help you meet those regulations.
REDUCING EMISSIONS
We've designed our trucks to use less fuel, which reduces engine emissions and carbon footprint, and there is zero fuel burn during retarding. —The optional Tier 4 Final engine reduces NOx and particulate matter. Rear axle filtration, extended life filters and extended maintenance intervals decrease the amount of waste contributed to the environment.
We also continue to research alternative energy sources such as biofuels (B20) and a liquefied natural gas-supplied Dynamic Gas Blending solutions to find new ways to reduce emissions. In addition, we preserve raw materials, conserve energy and reduce emissions through the Cat Reman program, which returns end-of-life components to like-new condition.
DESIGNED FOR SUSTAINABLE OPERATIONS
The 785D Mining Truck offers oil renewal systems, continuous rear axle filtration, extended life filters and extended maintenance intervals which aid in decreasing the amount of waste contributed to our environment. — The engine provides additional retarding by running against compression on downhill hauls. During retarding applications the engine ECM does not inject fuel into the cylinders for exceptional fuel economy. — Advanced Surface Technology (AST) is a replacement for hard chrome coatings on some steel parts, including suspension and hoist cylinder rods. This technology improves wear resistance and reduces repair time. Chrome has been eliminated to reduce environmental impact.
BUILT TO BE REBUILT
Cat trucks are designed to last over 100,000 hours, and many are going well beyond that. The frame, powertrain, engine and components are built to be rebuilt — using new, remanufactured or rebuilt parts and components — so you can take advantage of multiple lives of like-new performance at a fraction-of-new price.
Operating Cost
OPTIMIZED PAYLOAD
The Caterpillar designed machine monitoring system provides critical machine health and payload information to the operator and service personnel. Max Payload Speed Manager is a feature that aids in managing the Caterpillar 10/10/20 Overload Policy.
Based on target payload weight and overload settings, the VIMS system logs and warns the operator when the truck reaches overload after second gear reweigh. The truck will be limited to second gear at 1,750 rpm, and the automatic retarder speed setting is reduced to 1,750 rpm until the load is dumped.
MORE POWER TO GROUND
Lock-Up Torque Converter Combines maximum rimpull and cushioned shifting of torque converter drive with the efficiency and performance of direct drive — engages at approximately 8 km/h (5 mph), delivering more power to the wheels.
OPTIMUM POWER
Transmission Chassis Control (TCC) TCC uses electronically transferred engine rpm data to execute shifts at preset points for optimum performance, efficiency and clutch life.

COMMAND FOR HAULING
This autonomous hauling solution helps improve productivity, efficiency and profitability while reducing overall costs.
What if your trucks could respond to calls to the shovel, move into position, haul to dump points and even report for maintenance — all without an operator on board? That's what Cat Command for hauling enables.
But this autonomous Cat MineStar solution is more than just an operator-free system. It takes advantage of the most sophisticated technologies available to deliver a next-generation haulage solution — one that boosts safety, productivity and availability on busy mine sites, especially those in difficult or remote locations. With autonomous hauling, the future is here — and we're there to help you bring it to your operation.
DETECT
With the MineStar Detect proximity detection system, you can equip your 785D with cameras to give your operators a better view of what's happening around their equipment — or combine cameras and radar into a true object detection system that automatically alerts operators to hazards.
You can even add satellite capabilities to provide proximity warnings and avoidance zones, seat-belt monitoring that encourages operators to buckle up, and in-cab systems that intervene when they detect fatigue or distraction.
Road Analysis Control (RAC)
Optional system monitors haul road conditions by measuring frame rack and pitch to improve haul road maintenance, cycle times, tire life and fuel efficiency.
