Features

Two counterweight options provide improved lifting performance as well as versatility to meet transportation requirements.

New engine and hydraulic pump control technology improves operational efficiency and lowers fuel consumption by up to 10%.

A powerful Komatsu SAA4D107E-2 engine provides a net output of 86 kW 115 HP. This engine is EPA Tier 4 Interim and EU stage 3B emissions certified.

Komatsu Diesel Oxidation Catalyst (KDOC) reduces particulate matter using 100% passive regeneration. No DPF is required.

Komatsu Variable Flow Turbocharger provides optimum air flow under all speed and load conditions.

Komatsu's Closed Center Load Sensing (CLSS) hydraulic system provides quick response and smooth operation to maximize productivity.

Enhanced working modes are designed to match engine speed, pump delivery, and system pressure to the application.

Large LCD color monitor panel:
■ 7" high resolution screen
■ Provides "Eco-Guidance" for fuel efficient operation
■ Enhanced attachment control
■ Aux jack and (2) 12V Outlets

Rearview monitoring system (standard)

Equipment Management Monitoring System (EMMS) continuously monitors machine operation and vital systems to identify machine issues and assist with troubleshooting.

Enhanced working environment
■ High back, heated, and airsuspension operator seat
■ Integrated ROPS cab design (ISO 12117-2)
■ Cab meets ISO Level 1 Operator Protective Guard (OPG) top guard (ISO 10262)

The standard counterweight increases lifting performance up to 5%, while an optional heavier counterweight provides up to 15% more lift capacity when compared to the previous series.

Wide access service doors provide easy access for ground level maintenance.

Guardrails (standard) provide convenient access to the upper structure.

Battery disconnect switch allows a technician to disconnect the power supply before servicing the machine.

Komatsu designed and manufactured components Swing out cooler design provides easy access to service and clean the cooler assembly.

Swing out cooler design provides easy access to service and clean the cooler assembly.

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.
