1. The new arm interflow system more efficiently controls hydraulic fluid flow, and significant reduction of in-line resistance and pressure loss boosts fuel efficiency by about 16%*. The electronic-control common-rail engine features high-pressure fuel injection and multiple injection with improved precision.
  2. The highly efficient hydraulic system Improved Fuel Efficiency Contributes to High Performance minimizes fuel consumption while maximizing power. With nimble movement and superior digging power, this excavator promises to improve your job productivity.
  3. Structural design increases strength, while eliminating hydraulic problems. Enhanced durability takes productivity to a new level.
  4. A work environment that is quieter and more comfortable. A cab that puts the operator first is key to improved safety.
  5. KOMEXS uses satellite communication and internet to relay data, and therefore can be deployed in areas where other forms of communication are difficult. When a hydraulic excavator is fitted with this system, data on the machine’s operation, such as operating hours, location, fuel consumption, and maintenance status can be obtained remotely
