Features
Cat C4.4 ACERT Tier3 urea-free engine with 4.4L displacement & 68kW net power, reliable 4-cylinder design, abundant low-speed torque for municipal & small quarry jobs, compatible with low-grade diesel to cut total ownership cost.
13.5t extended 7-roller wide undercarriage with low ground pressure avoids sinking on soft muddy ground; heat-treated heavy-duty track components extend service life.
Upgraded regenerative load-sensing hydraulics with 3 power modes reduce fuel consumption by 9% vs Cat 312D, balancing high hourly production and fuel efficiency for digging & breaker tasks.
Reinforced thick wear-resistant boom & stick with strengthened welds reduce breakdown frequency on urban demolition and small rock sites.
Factory pre-installed auxiliary hydraulics support breakers, grapples and quick couplers without extra refitting.
Compact 7670mm transport length for easy flatbed haulage, perfect for municipal repair, villa renovation, small foundation and pipeline projects.
All ground-level service access points eliminate climbing work for fluid and filter replacement, shortening maintenance downtime greatly.
