Komatsu PC55MR-5

Komatsu PC55MR-5

New Komatsu PC55MR-5 Excavator for Sale

The PC55MR-5 has a maximum track width of only 77” and a tight minimum swing radius, yet delivers outstanding performance in reach, digging depth, bucket break-out force and lifting capabilities. From the high strength X-Track frame to the ample castings in the boom and arm, the PC55MR-5 is made to deliver high performance for years to come.

  • NEW ENGINE TECHNOLOGIES: The PC45MR-5 is equipped with a clean engine that complies with the EPA Tier 4 Final emission regulations. The engine uses proven environment friendly technologies such as an exhaust gas aftertreatment system, an electronically-controlled cooled Exhaust Gas Recirculation (EGR) system, and an optimum fuel injection system using a common rail. These technologies, combined with Komatsu’s own electronic control system, minimize environmental impact and improve fuel economy.
  • ELECTRONIC CONTROL SYSTEM: The engine and hydraulic system are optimally controlled according to the operating conditions. The hydraulic loss reductions also help reduce both fuel consumption and environmental impact.
    • Fuel consumption: Reduced Up To 5% Fuel consumption

    • Comparison with Komatsu’s prior models: The average working pattern is analyzed by KOMTRAX. The above data may differ from actual fuel consumption depending on the type of work. The fuel consumption data is based on in-house comparison test results.

  • MULTI-FUNCTION MONITOR: Various alerts and machine information are displayed in a simple format. Useful information such as operation records, machine setting and maintenance data are also provided. The operator can easily switch screens.
  • EFFICIENT AND EFFECTIVE MAINTENANCE: The side opening engine hood and large side cover provide easy access for daily inspections. The cab or platform can be tilted up together with the operator’s seat to gain access for major maintenance or repair work.
  • MINIMUM SWING RADIUS: The extra-small swing radius with minimum rear protrusion from the tracks (60mm for PC45MR-5) allows the operator to concentrate on work in confined areas.
  • ENHANCED WORKING ENVIRONMENT: 
    • Mid back, suspension operator seat
    • Integrated ROPS cab design (ISO 3741:2008)
    • Cab meets ISO Level 1 Operator Protective Guard (OPG) top guard (ISO 10262)
    • Aux jack and 12V outlet
    • Radio-ready cab
