730E-10 Electric Drive Mining Truck

The Komatsu 730E-10 electric drive mining truck offers a payload increase, 205 short tons, and the durability and reliability found in all our electric drive trucks.

Powered by our dual stage SSDA16V159E-2 engine with 2000 GHP, available with U.S. EPA Tier 4 Final Certification, the 730E-10 also offers 3400 HP retarding, available KomVision all-around monitoring system, and our improved automotive styled Operator Cab.



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, the prior platform’s durability is continued. 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 non-pollutants. Internal cleaning of the SCR is performed through an automatic process.


PLM™ IV is an electronic system that monitors and records payload information for Komatsu’s off-highway mining trucks. The accurate and reliable payload measurement system is designed to help optimize payload, maximize productivity and reduce the life cycle cost of the machine. PLM™ IV tracks and records the following key production parameters:

  • Payload
  • Empty Carry-Back
  • Operator Identification
  • Haul Cycle, Loading, Dumping Time and Date
  • Distance Traveled (Loaded and Empty)
  • Cycle Time Information
  • Maximum Speeds (Loaded and Empty)
  • TMPH Estimate for Front and Rear Tires
  • Average Speed (Loaded and Empty)


Structurally Enhanced Frame Design
By using advanced computer-aided design, finite element analysis, and full-scale dynamic and static testing, the frame has been designed to carry 186 metric tons 205 short tons and provides the high structural reliability Komatsu is known for.

Castings Used 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.


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.
