HITACHI ZX225USRLC CRAWLER EXCAVATOR

Technical Description

The Hitachi ZX225USRLC is a medium-sized hydraulic excavator designed for high productivity and efficiency in varied construction and excavation tasks. It features three boom and stick configurations with differing reach and digging capabilities, where Option 1 provides a max cutting height of 30.1 ft, digging depth of 19.7 ft, and max reach along ground of 29.8 ft; Option 2 increases these values to 31.5 ft, 21.9 ft, and 32 ft respectively; and Option 3 further extends to a max cutting height of 33.6 ft, max digging depth of 26.8 ft, and max reach along ground of 36.5 ft. The machine supports bucket capacities from 0.7 to 1.6 cubic yards, with a reference capacity of 1.1 cubic yards. Its overall dimensions include a ground clearance of 1.5 ft, cab height of 9.7 ft, track length on ground of 11.1 ft, width across tracks at 9.2 ft, and a shipping length ranging from 29.6 to 31.1 ft depending on configuration. Powered by a turbocharged, intercooled AA-6BGIT engine displacing 396.3 cubic inches, the ZX225USRLC delivers 147 horsepower (110 kW) at 2100 rpm with a maximum torque of 405.7 lb-ft at 1600 rpm. The hydraulic system provides a pump flow capacity of 102.5 gpm and operates at a relief valve pressure of 4980 psi with a fluid capacity of 52.9 gallons. Operating weight is approximately 49,604 lbs. The undercarriage delivers a ground pressure of 6.9 psi and travels up to 3.3 mph. The swing mechanism operates at up to 13.3 rpm, with a swing fluid capacity of 1.7 gallons. Key dimensions include a tail swing radius of 6.6 ft and a track gauge of 7.3 ft. The excavator features a compact design with a relatively short rear-end swing radius allowing efficient operation in confined spaces while maintaining stability.
