Caterpillar has introduced the new 789 Mining Truck, built to improve performance, connectivity, and comfort. Caterpillar says the new design offers a weight advantage to haul more material every load and deliver a cost-per-ton advantage.
CAT says the 789 moves more material with less fuel, offering up to 9 percent reduced fuel consumption compared to the Tier II design. The 789 is said to have an advanced powertrain that delivers better shifting and acceleration.
With a 3516E engine, the 789 offers the highest horsepower in its class, featuring 10 percent more payload and is over 5 percent faster on grade than other trucks, according to Caterpillar.
The new engine features design modifications to the camshaft and piston for better fuel efficiency, as well as changes to the cylinder head and crankshaft. Caterpillar says the new engine design delivers 12 percent more durability than the 3516C. A beefed-up engine improves power up steep grades and over rough terrain.
The 789 features Advanced Power Electronic Control Strategy (APECS) transmission technology that delivers easier gear transition leading to reduced cycle times. APECS offers more continuous torque and rimpull to deliver more power to the ground, making it possible to use a higher gear on grade to optimize fuel efficiency.
There are also body configurations to choose from for the 789 to meet the needs of different working conditions. The high-performance body maximizes payload by reducing weight by up to 5.5 tons.
The original standard, dual slope body, provides excellent load retention, and the X body features the latest structural designs and offers more volume at a lower weight.
The 789-mining truck has a larger cab aimed at making life easier on the operator. The cab is 17% wider, with a walk-through design, complete with an adjustable center console that offers 34% more operator space, 11% more legroom and 19% more shoulder room.
Caterpillar says the cab is a lot quieter and includes automated temperature control and cab filtration for a more comfortable environment.
Two screens provide important machine data, controls and guidance information, and applications like Cat MineStar to reduce the number of required displays.
Operators get real-time feedback on truck operation to maximize productivity, while more accurate measurements on the payload monitoring system deliver improved load tracking. Operators can also see all the eway around the truck with cameras complete with object detection technology.
All 789 trucks come with Cat Product Link Elite with standard connectivity via cellular 4G/LTE and available cellular/satellite radio for reliable data transfer.
The ability for operators to access accurate data quickly is a huge advantage to project operations. The information helps with maintenance, diagnostics, project strategy, and basic machine operation. New telematics connects cloud-based applications such as Cat MineStar Solutions. Available MineStar Fleet, Detect and Health Equipment Insights, along with standard haul road analytics, help to improve performance, maintenance and machine life.
Many components, including a new modular HVAC (heating, ventilation and air conditioning) system, decrease downtime when parts need to be replaced. A modular radiator enables rebuilds to be completed off the truck to reduce downtime.
Also, main access points for maintenance have been centralized and made easier to access and features an extended 12,000-hour coolant life and double the hydraulic and transmission filter life to 1,000 hours to reduce service time.
