Equipment Overview
The Komatsu PC78MR is an 8.27-tonne midi excavator specifically designed to work in tight spaces and hard-to-reach areas. It’s equipped with a swing offset boom, letting it work efficiently around obstacles, and can be supplied in customised configurations with special features and options to suit different applications. The compact footprint and manoeuvrability make it well suited to confined urban and utility work where a larger excavator wouldn’t fit.
Power comes from a Komatsu engine producing 40.5 kW (54 hp) at 1,850 rpm. The HydrauMind hydraulic system is a closed-centre design with load sensing, delivering a maximum pump flow of 160 L/min (2 x 80 L/min) for smooth, responsive digging and lifting performance. Bucket digging force reaches around 61 kN, and arm crowd force around 41.5 kN with the standard 1,650 mm arm, giving the machine solid performance for its size class.
