CAT 798 AC Mining Dump Truck Specifications, 4000 hp, 410 Tons Payload

CAT 798 AC

CAT 798 AC Mining Dump Truck Overview:

The Cat 798 AC delivers powerful performance and it has a payload capacity of 410 tons. This Caterpillar machine is easy to maintain and provides more reliability than any other mining truck. You can read Cat 798 AC specifications by checking the table below.

It is built with Cat TorqueBoost technology, which makes it possible to work in the toughest conditions. You can access the Engine from both sides and this makes it easy to maintain the engine easier.

This 798 AC Truck model integrated FOPS, ROPS, and door sensor warning for safety concerns. Its optimized drive integration provides more power to the ground.

The components of this machine are made by Caterpillar including software and electronics components. This is the only single-source electric machine in its size class of dump truck and full support of Cat dealers and network around the globe with fast and efficient parts fulfillment.

The AC drive system of this truck is a high voltage system that runs at a lower voltage current than most of its capacity mining dump truck and it is equipped with an Enhanced Engine Oil Filtration package that eliminates the need for an engine oil filter change in frequent intervals.

The company is also doing research in alternative energy sources including LNG and biofuels. The engine is specially designed to use less fuel and emit less carbon and centrifugal oil filters and other filters are compulsory on all engines.

Cat extended life coolant protects the system up to -35°C. It is a 210 GPM fast fuel system and has different lighting signals including Headlights (4 high beams, & 4 low beams), Directional LED signals (rear & front), Stop tail LED lights, Engine compartment LED, Payload indicator, and payload digital display, Backup LED, and other hazard indicators.

CAT 798 AC Truck Engine:

The 798 AC is powered by a C175-16 engine and this engine is available in two horsepower options. This engine design delivers a long life. Its two side walkways, make it easy to maintain and easy to access different parts.

Its efficient design makes it possible to lower repair costs and move more weight per gallon and moves faster.

  • 3,500 hp (2,610 kW), 4,150 hp (2095 kW)
  • Turbocharging
  • More than one point oil pressure sensing
  • Charging alternator (225 amp)
  • 18% more torque
  • Self-cleaning & centrifugal oil filter

CAT 798 AC Cameras and Alerts:

You can place cameras to give your driver a wide view around the machine and you can also combine radar and cameras that alert the operator. You can also add satellite features to provide proximity warnings.

798 AC High Efficiency Body:

CAT vehicle bodies are specially designed to be an integral part of the entire vehicle system, which that confirms you achieve maximum chassis life.
