The Sumitomo SH220LC excavator is a robust mid-size hydraulic excavator with multiple boom and stick options optimizing reach and digging depth. It features a powerful 153 hp (114 kW) Isuzu 6BG1T engine with 396.1 cu in displacement, delivering reliable performance at 2150 rpm. The machine operates at an operating weight of approximately 51,808 lbs, balancing heavy-duty capability and mobility with a maximum travel speed of 3.5 mph and low ground pressure of 6.9 psi. The SH220LC supports bucket capacities ranging from 1.0 to 1.8 cubic yards, with a reference capacity of 1.2 cu yd, suitable for a wide range of excavation tasks. The excavator's hydraulic system comprises a high-capacity valve and electronically controlled pumps delivering smooth, energy-efficient operation with a relief valve pressure of 4550 psi. Enhanced features such as Spool Stroke Control (SSC), Boom-Down Energy Saving (BES), and Automatic Energy Saving (AES) maximize fuel efficiency and performance. Three boom and stick option configurations allow maximum cutting heights from 30.6 ft to 32.7 ft and digging depths from 20.8 ft to 24.3 ft, supporting vertical wall digging up to 21.9 ft and ground reaches over 35 ft. The robust undercarriage includes 23.7 in triple grouser shoes and a track gauge of 8.5 ft, providing excellent stability and maneuverability on tough terrain. Dimensions include a shipping length of 32.7 ft and height of 10.1 ft, with a cab height of 9.6 ft and ground clearance of 1.6 ft. The swing mechanism provides 10.4 rpm swing speed and a tight 9.9 ft tail swing radius, ideal for confined worksites. Fuel and hydraulic capacities are 81.9 gal and 58.2 gal respectively, ensuring sustained operation. Overall, the Sumitomo SH220LC integrates advanced engine technology, hydraulic sophistication, and versatile configurations to deliver reliable, efficient excavation performance for diverse construction demands.
