Features
Equipped with turbocharged SAA4D95 China IV engine, 48.8kW net power & strong low-speed torque, 40% higher performance than PC56. Passive DOC regeneration without urea reduces maintenance cost.
Ultra-short US tail swing (1220mm) avoids wall collision in residential zones & factory sites. Optional offset boom enables trenching close to walls without repositioning the machine.
Standard 3.1m boom + 1.7m arm with 0.28m³ rock bucket delivers deeper digging & larger load capacity than 6-ton models. Optional short breaking arm & long deep-dig arm cover municipal, construction, landscaping & demolition work.
Dual regenerative main pumps + independent dozer pump ensure smooth combined movements, stable pressure during all-day hammer operation, fully compatible with 78-class medium hydraulic breakers.
Reinforced heavy-duty boom & stick with fully sealed dust-proof pins resist abrasion & deformation during long-term stone & heavy earth work.
Factory pre-installed bi-directional auxiliary hydraulics support breakers, grapples & rippers without pipe modification, multi-purpose for municipal breaking and foundation excavation.
Standard Komtrax telematics provides real-time tracking of working hours, fuel consumption & location for easy rental fleet management.
All ground-level service access points allow single-person daily maintenance without climbing.
