830E-5 Electric Drive Mining Truck

Komatsu’s 830E-5 offers an increase in payload with a 250 short ton payload mining truck with the proven durability and reliability found in its predecessor.

The 830E-5 offers the power of the SDA16V160 engine with U.S. EPA Tier 4 Final Certification and 2500 HP. With on-demand cooling for the Control Cabinet, Wheel Motors and Grids, the 830E-5 has improved load carrying capacity and reduced parasitic loss. With 4300 HP retarding, available KomVision all-around monitoring system and our improved automotive styled Operators Cab, this 830E-5 takes top of the class.


Tier 4 and Electrification

Evolutionary, not Revolutionary Design
Komatsu’s Tier 4 solution begins with a base engine which is very similar to the previous Tier 2 platform. In keeping the basic operation of the engine the same, durability is assured. Utilizing High Pressure Common Rail fuel delivery ensures atomization of the fuel/air mixture to a level which reduces particulate matter, meeting U.S. EPA Tier 4 standards.

Komatsu After-treatment
Removal of NOx is accomplished by treating the exhaust through Selective Catalytic Reduction (SCR). The introduction of Diesel Exhaust Fluid (DEF) into the SCR canister generates a chemical reaction which breaks down the oxides of nitrogen into oxygen and nitrogen, both nonpollutants. Internal cleaning of the SCR is performed through an automatic process.

On-Demand Cooling

  • Separate cooling circuits for control group and wheel motor systems
  • Allows intelligent control of cooling
  • Maintain optimal temperatures for each system

Alternator Self-Cooling Only

  • Reduced impeller size by 25%
  • Reduced cooling housing/impeller

As part of a complete service and support program, Komatsu equips every mining and quarry sized machine with KOMTRAX Plus 2®. By using a satellite-based communication system, KOMTRAX Plus 2® offers a new vision of monitoring your valuable assets. By providing insight to critical operating metrics the user can manage increased availability, lower owning and operating costs and maximize fuel efficiency.

The information available through KOMTRAX Plus 2® allows service personnel to review faults and trends, improve the quality of the troubleshooting process and reduce unscheduled machine downtime.


Structurally Enhanced Frame Design
By using advanced computer-aided design, finite element analysis, and full-scale dynamic testing, the frame has been designed to carry 227 metric tons 250 short tons and provides the high structural reliability Komatsu is known for.

Castings in High Stress Areas
To increase frame reliability, steel castings have been incorporated at key frame pivot points and critical load bearing portions of the structure. This includes the rear body pivot and horsecollar sections.

Simple and Reliable Hydraulic System
The hydraulic system is a proven and reliable design with fewer parts than other OEMs. The system utilizes a single tank, providing one common source of fluid for steering, braking, and hoisting. In-line, replaceable filtration elements provide protection from hydraulic system contamination, making the system easier to service.
