Top Features

Fuel Efficient Tier 4 Final Engine

  • The Komatsu SAA6D125E-7 EPA Tier 4 Final certified engine uses a lower exhaust gas recirculation rate, high efficiency combustion chamber design and high pressure common rail fuel injection system to help improve fuel efficiency.

  • Komatsu Variable Geometry Turbocharger (KVGT) with a hydraulic actuator delivers optimum air flow under all speed and load conditions to improve low speed engine response.

  • A Komatsu Diesel Particulate Filter (KDPF) and Selective Catalytic Reduction (SCR) system with a large capacity AdBlue/DEF tank provide clear engine emissions with a high degree of passive regeneration and minimal work cycle interruption.

  • An integrated vehicle sensor network coordinates engine and hydraulic control while enhancing vehicle monitoring and onboard diagnostic capabilities

Operator Comfort

  • A reinforced cab structure with integrated ROPS (ISO 12117-2) design, sound deadening materials and isolation cab mounts help maintain a quiet and comfortable operating environment.

  • An automatic climate control system and heated high back air suspension operator seat provides improved comfort. Console mounted armrests slide independently or together with the seat.

  • An auxiliary input allows operator to connect to an MP3 player and hear sound through the cab stereo speakers. 2 standard 12V outlets provide power for mobile devices.

  • A high resolution color LCD monitor panel displays vehicle information and provides integrated control of machine functions with easy navigation screens, and enhanced diagnostic capability.

  • A standard rearview monitoring system provides a view of the working area directory behind the machine

Advanced Hydraulic System

  • A closed center load sensing hydraulic system with quick arm return circuit improves efficiency and provides smooth operation, quick cycle times, and great multifunction operation while helping reduce fuel consumption.

  • Large displacement hydraulic pumps operate at lower engine RPM to reduce fuel consumption without impacting performance.

  • Variable Speed Matching logic manages engine power with hydraulic demand to optimize hydraulic power output across the entire speed and load range.

  • Easy to access control pattern change valve makes it easy to switch from excavator to backhoe control pattern.

Lift Capacity and Stability

  • The PC490LC-11 has a large machine design with increased operating weight and reinforced structures for good lift capacity and lateral stability.

  • Reinforced undercarriage design features strengthened track shoes, links, rollers, idlers, sprockets, track & center frames for added durability.

  • A heavy duty revolving frame and high capacity swing bearing provide added reliability. A heavy counterweight improves stability when working over side or in long reach applications.

  • An optional variable width undercarriage increases track gauge by 5.5% and provides up to 7% better over side lift capacity while keeping the machine easy to transport.

Improved Serviceability

  • Handrails on the upper structure provide a convenient and secure work area in front of the engine and a new step provides easier access for filling the AdBlue/DEF tank.

  • A battery disconnect switch cuts electrical power to the machine during service or electrical work. Sealed connectors in the electrical harness and O-Ring face seal fittings in the hydraulic system improve machine reliability.

  • Service points are grouped for convenience and filters are easily accessible in the engine compartment. A 24V fuel priming pump easily bleeds air from the fuel system.

  • KOMTRAX® provides GPS location and vehicle performance information to aid in better machine management. Komatsu Advanced diagnostic system does not require a laptop or additional software to use.

  • Komatsu Care Complimentary scheduled maintenance for 3 years or 2,000 hours Service is performed by factory certified technicians using komatsu Genuine parts and fluids (Low ash engine oil required).
