Features
Equipped with Komatsu 4D88 4-cylinder China IV direct injection engine, 28.9kW high power output with strong low-speed torque, 30% higher breaking & loading power than 3-ton mini excavators. Low vibration & noise fit residential and basement work, universal cheap spare parts cut maintenance cost.
Genuine MR zero-tail swing design with only 920mm tail swing radius, avoids wall collision in narrow alleys and indoor demolition; retractable track width down to 1400mm to pass underground garages and narrow doorways.
Standard 2.62m boom + 1.48m arm matched with 0.16m³ rock bucket delivers much larger digging depth & bucket volume than PC30MR. Optional short breaking arm & long deep-dig arm cover municipal trenches, landscaping, indoor demolition and light quarry breaking.
Bi-directional high-flow regenerative hydraulics support continuous heavy hammer work with ultra-smooth fine control for tree digging and slope finishing, friendly for new operators with seamless combined movements.
Reinforced heavy-duty boom & stick with thick high-strength steel, fully sealed dust-proof pins prevent oil leakage and abrasion during long-term stone & earth work, lower overall failure rate.
Factory pre-installed bi-directional auxiliary hydraulic lines support 45-class breakers, grapples & rakes without extra pipe refitting, multi-purpose for municipal breaking and yard excavation.
Basic Komtrax telematics enables real-time monitoring of working hours, fuel consumption and location via mobile devices for easy rental & small construction fleet management.
All ground-level service access points allow single-person daily maintenance without climbing work.
