KOMATSU PC220-6 EXCEL CRAWLER EXCAVATOR

Technical Description

The Komatsu PC220-6 EXCEL is a heavy-duty hydraulic excavator designed for versatile earthmoving and construction applications. It features a powerful SA6D102E engine with a displacement of 358.9 cubic inches, delivering a net power output of 152.9 hp (113 kW) at 2100 rpm. The machine operates at an impressive weight of 48,303 lbs, providing stability and robust performance on demanding sites. Its hydraulic system includes a pump flow capacity of 114.2 gpm with a relief valve pressure rated at 4620 psi, enabling precise and powerful boom, stick, and bucket operations. The excavator offers multiple boom and stick configurations, each optimizing reach and digging depth: Option 1 extends a maximum cutting height of 29.8 ft and a digging depth of 19.3 ft, whereas Option 4 enhances these capabilities to 31.6 ft in cutting height and 24.2 ft in digging depth, with corresponding maximum reach along ground up to 34.4 ft. Bucket capacities range from 1 to 1.7 cubic yards, with a reference size of 1.4 cubic yards suited for general excavation. Key dimensions include a ground clearance of 1.5 ft, cab height of 9.6 ft, and an 11.4 ft track length on the ground, providing maneuverability and operator comfort. The undercarriage delivers a max travel speed of 2.4 mph and maintains ground pressure at 8.3 psi, balancing traction and ground preservation. The swing mechanism rotates at 12.4 rpm enabling smooth operation. Transport dimensions vary slightly with configuration but maintain a shipping height near 10.3–10.8 ft and length just over 32 ft, supporting ease of transport between job sites. Overall, the PC220-6 EXCEL integrates power, precision, and flexibility for medium-to-large excavation projects.
