- PC18MR-2
Tight Tail Swing
The operator can focus on the work in front and worry less about rear swing impact in confined areas with 80 mm 3.2" overhang on the rear.
Large Operator’s Space
The operator can operate the machine comfortably due to a suspension seat with adjustable seat back. The operator can enter and exit easily from both sides due to increased foot space and two-post ROPS/FOPS (level 1) canopy.
Two-Post ROPS/FOPS Canopy/Cab
• Each canopy meets regulations for ROPS/FOPS (level 1)
• Excellent operator visibility
Digging Force
Komatsu Closed-Center Load Sensing System (CLSS) provides exceptional productivity combined with outstanding stability and superb fine control.
Adjustable Blade Width
Blade width may be adjusted manually to increase width from 980 mm 38.6" to 1300 mm 51.2".
Lifting Capacity
The MR-2 series excavators offer high lifting capacities and stability in a tight tail machine design.
Automatic Two-Speed Travel
In high speed mode, travel speed is automatically shifted from high speed to low speed according to the load on the machine.
Expandable Undercarriage
The PC18MR-2 is able to pass through narrow entry ways due to its retractable undercarriage. Once in position, the undercarriage may be expanded for greater stability.
Tilt Forward Operator’s Compartment
The operator’s compartment tilts forward allowing easy access to hydraulic and engine components.
