Features
Cat C4.4 turbocharged Tier3 urea-free engine with 4.4L displacement & 68.5kW net power, low-pressure common rail fuel system compatible with low-grade diesel, stable low-speed torque for municipal & small quarry work, cutting total ownership cost without after-treatment consumables.
13.6t extended 7-roller wide undercarriage with low ground pressure avoids sinking on soft muddy ground; heavy heat-treated track components extend service life.
Upgraded regenerative load-sensing hydraulics with 3 power modes reduce fuel consumption by 7% vs Cat 312E, balancing high hourly production and fuel efficiency for digging & breaker tasks.
Reinforced thick wear-resistant boom & stick with full strengthened welds extend service intervals for urban demolition and small rock sites, reducing downtime drastically.
Factory pre-installed auxiliary hydraulics support breakers, grapples and quick couplers without extra refitting.
Compact 7730mm 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.
