HITACHI ZX270 LC CRAWLER EXCAVATOR

Technical Description

The Hitachi ZX270 LC excavator is a mid-size hydraulic excavator engineered for versatile digging and loading operations. It features three boom/stick configurations that optimize reach and depth capabilities: Option 1 offers a max cutting height of 31.7 ft, digging depth of 21.5 ft, loading height of 22.2 ft, and max reach along ground of 32.4 ft; Option 2 increases these to 32.8 ft, 23.8 ft, 23.2 ft, and 34.6 ft respectively; Option 3 maximizes performance with a cutting height of 33.4 ft, digging depth of 25.9 ft, loading height of 23.8 ft, and ground reach of 36.4 ft. The excavator’s max vertical wall digging depth spans from 17.4 to 21.9 ft depending on the boom/stick selection. Bucket capacities range from 1.1 to 1.9 cubic yards, providing flexibility for various material handling tasks. The unit measures approximately 34 ft in length, with a shipping height between 10.5 and 11.3 ft and a track width of 10.5 ft, supporting stable operation on rugged terrain with a ground clearance of 1.7 ft and a track gauge of 8.5 ft. It operates on a powerful turbocharged, intercooled AA-6BGIT engine with a displacement of 396.3 cu in, delivering a net power output of 173 hp at 2150 rpm and a max torque of 470 lb-ft at 1800 rpm. The hydraulic system runs at a relief pressure of 5050 psi with a pump flow capacity of 110.5 gpm, ensuring efficient power transmission for digging and swinging functions. The swing drive operates at 10.6 rpm, and the excavator achieves a max travel speed of 3.1 mph with minimal ground pressure of 7.6 psi, reducing soil disturbance. The machine is equipped with 48 track shoes per side, 9 track rollers, and 2 carrier rollers, optimized for durability and track stability in various working conditions. Overall, the Hitachi ZX270 LC blends powerful performance with precise control for demanding excavation applications.
