Features :- Komatsu Excavators
- PC78MR-6
Tight Tail Swing - Operators can focus more on the work in front of them and worry less about rear swing impact even in confined areas with only 6" / 150 mm protrusion over the tracks.
Powerful Engine With Turbocharger - Engine meets the EPA Tier 2 emissions regulations.
Swing Boom - The PC78MR-6 efficiently works against side walls by utilizing swing boom.
Two Working Modes provide a choice between extra workload and low fuel consumption.
Back Fill Blade - The PC78MR-6 features a standard back fill blade that can quickly and conveniently fill trenches and cleanup jobsites.
New Pressure-Compensated CLSS HydrauMind Hydraulic System - Even when two or more actuators are operated simultaneously, the PC78MR-6’s pressure - compensated CLSS system ensures each actuator works according to its control input regardless of the size of the load. This gives the operator precise control at all times.
Engine Speed Sensing = Optimum Power - Power utilized by main pump is adjusted automatically in accordance with the engine speed. That means this computerized system maintains optimum engine speed even under high load conditions.
Against Side Wall - PC78MR-6 works efficiently by utilizing swing boom.
Advantage Even in Confined Job Site - Road & Bridge Work
