Features
A larger machine design and reinforced undercarriage provide up to 10% more lift capacity, improved lateral stability, and added reliability.
New engine and hydraulic pump control technology improves operational efficiency and lowers fuel consumption.
A powerful Komatsu SAA6D125E-6-A engine provides a net output of 268 kW 359 HP. This engine is EPA Tier 4 Interim and EU stage 3B emissions certified.
Komatsu Variable Geometry Turbocharger (KVGT) uses a hydraulic actuator to provide optimum air flow under all speed and load conditions.
Komatsu Diesel Particulate Filter (KDPF) captures 90% of particulate matter and provides automatic regeneration that does not interfere with daily operation.
Large displacement high efficiency pumps provide higher flow output at a lower engine speed and efficient operation.
Two boom mode settings provide power mode for maximum digging force or smooth mode for fine grading operations.
Komatsu Closed Center Load Sensing (CLSS) hydraulic system provides quick response amd smooth operation to maximize productivity.
Large LCD color monitor panel:
■ 7" high resolution screen
■ Provides "Eco-Guidance" for fuel efficient operation
■ Enhanced attachment control
Rearview monitoring system (standard) Enhanced working modes are designed to match engine speed, pump delivery, and system pressure to the application.
Enhanced working environment
■ High back, heated, and air suspension operator seat
■ Integrated ROPS cab design (ISO 12117-2)
■ Cab meets ISO Level 1 Operator Protective Guard (OPG) top guard (ISO 10262)
Equipment Management Monitoring System (EMMS) continuously monitors machine operation and vital systems to identify machine issues and assist with troubleshooting.
Komatsu designed and manufactured components
Hydraulically driven variable speed fan reduces parasitic load on the engine to improve fuel consumption and can be reversed to simplify cooler maintenance.
Guardrails (standard) located on the machine upper structure provide a convenient work area in front of the engine.
Battery disconnect switch allows a technician to disconnect the power supply before servicing the machine.
Heavy duty boom design with large one piece castings provide increased strength and reliability.
KOMTRAX® equipped machines can send location, SMR and operation maps to a secure website utilizing wireless technology. Machines also relay error codes, cautions, maintenance items, fuel levels, and much more.
