Technical Description

The Komatsu PC220LC-7 is a robust hydraulic excavator designed for high productivity and durability in demanding construction and earthmoving tasks. It is powered by a turbocharged Komatsu SAA6D102E-2 engine delivering 167.7 hp (125 kW) at 2000 rpm, meeting EPA Tier 2 emission standards while maintaining fuel efficiency. The machine features a hydraulic system with a dual-pump configuration and 116 gpm flow capacity, providing smooth and powerful work equipment movements. The PC220LC-7 offers three boom/stick excavator options with varying arm crowd and bucket digging forces, maximizing versatility across different job requirements. For example, Option 1 provides an arm crowd force of 34,845 lbs (SAE) and bucket digging force of 44,287 lbs (ISO), with maximum digging depths up to 19.2 ft and maximum digging reach near 30.5 ft. Option 3 extends digging depth to 22.8 ft with slightly lower bucket and arm forces. Key operational specifications include a maximum digging height up to 32.9 ft, max dumping height around 23 ft, and a minimum swing radius near 130 inches, supporting efficient maneuvering and reach in confined spaces. The undercarriage supports a drawbar pull of 45,411 lbs with low ground pressure (7 psi), enhancing stability and mobility. Travel speed reaches up to 3.5 mph with automatic three-speed shifting. The cab is spacious and well-pressurized with air conditioning and low noise design, ensuring operator comfort. Maintenance is simplified via remote-mounted engine oil filters and extended lubrication intervals, reducing downtime. Enhanced frame rigidity and Komatsu components deliver long-term reliability, making the PC220LC-7 a powerful, efficient excavator built for heavy-duty applications.
