SUMITOMO SH300LC-2 CRAWLER EXCAVATOR

Technical Description

The Sumitomo SH300LC-2 is a heavy-duty hydraulic crawler excavator engineered for versatile earthmoving tasks with multiple boom and stick options. Its maximum cutting height ranges from 32 ft to 34.7 ft depending on the boom/stick configuration, while maximum digging depths vary between 20.9 ft and 26.9 ft. The machine offers a maximum reach along the ground up to 39 ft, and vertical wall digging depths reaching 23.4 ft, providing substantial operational range for trenching, loading, and excavation work. The excavator has a shipping height of 11.1 ft and a length of 35.7 ft in all configurations, facilitating transport. It is equipped with a 226.7 hp (169 kW) 6D22T diesel engine displacing 679.9 cubic inches, delivering robust performance at 1650 rpm. Fuel capacity is 153.3 gallons, with hydraulic fluid capacity of 84.6 gallons operating at a relief valve pressure up to 4622 psi, ensuring strong hydraulic power for attachments and boom articulation. The operating weight is approximately 72,973 lbs, supported by a wide track gauge of 8.6 ft and a ground clearance of 1.7 ft, balancing stability and mobility. Track shoes measure 23.7 inches, enabling travel speeds up to 3.2 mph while maintaining low ground pressure of 10 psi to minimize soil disturbance. The bucket capacities range from 1.5 to 2.1 cubic yards, with a referenced standard size of 2 cubic yards, suitable for large volume material handling. The machine features a tail swing radius of 10.6 ft and a cab height of 10 ft, combining operator visibility with maneuverability in confined spaces. Swing speed is rated at 9.5 rpm, facilitating efficient rotation during digging operations. Overall, the SH300LC-2 is a reliable mid- to large-sized excavator designed for demanding construction and mining applications requiring high digging performance, reach, and operational flexibility.
