HITACHI ZX120 CRAWLER EXCAVATOR

Technical Description

The Hitachi ZX120 is a compact hydraulic excavator engineered for versatile earthmoving and material handling applications. This machine features a turbocharged, intercooled Isuzu CC-4BG1TC engine delivering 88 horsepower at 2,150 rpm with maximum torque of 253 lbs-ft, providing robust power for demanding jobsite conditions. The excavator operates at 27,600 lbs with a compact footprint of 25 feet in length and 8.9 feet in width, facilitating maneuverability in confined spaces. The ZX120 accommodates three boom and stick configurations, offering maximum digging depths ranging from 16.9 to 19.9 feet and maximum reaches between 25.5 and 28.3 feet along the ground. Maximum cutting heights extend from 27.5 to 29.2 feet depending on configuration selection. The bucket system provides capacities from 0.3 to 0.9 cubic yards with a standard 0.7 cubic yard reference capacity. The hydraulic system operates at 4,980 psi relief pressure with a pump flow capacity of 55.5 gallons per minute, delivering efficient excavation force through variable-displacement axial piston motors. The swing mechanism rotates at 13.7 rpm via a shear-type ball bearing design. Ground pressure measures 4.2 psi with maximum travel speeds of 3.4 mph in high gear, enabling effective site mobility. With a 66.1-gallon fuel capacity and comprehensive fluid systems totaling 34.4 gallons of hydraulic fluid, the ZX120 sustains extended operational periods. The 24-volt electrical system includes a 50-amp alternator for powering auxiliary equipment, making this machine suitable for construction, demolition, and material processing applications.
