Technical Description

The Hitachi ZX170W-3 is a wheeled excavator engineered for versatile earthmoving and material handling applications. Powered by an Isuzu AI-4HK1X turbocharged, intercooled four-cylinder diesel engine rated at 143 horsepower (107 kW) and producing 398.3 foot-pounds of torque, this machine delivers robust performance in demanding job sites. The excavator operates on a two-speed power shift transmission with variable displacement axial piston travel motors, achieving a maximum travel speed of 21.8 miles per hour with impressive gradeability of 70 percent. The ZX170W-3 features three interchangeable boom-stick configurations, providing operators with digging depths ranging from 16.3 to 19.2 feet and maximum reach along ground from 27.9 to 30.7 feet, accommodating diverse excavation requirements. Operating at 36,600 pounds, this compact wheeled platform maintains an overall width of 8.4 feet and wheelbase of 8.4 feet, enabling maneuverability in confined spaces while supporting an outrigger spread width of 11.1 feet for enhanced stability. The hydraulic system incorporates two variable displacement axial piston pumps delivering 105.7 gallons per minute at a relief pressure of 4,974.8 PSI, coupled with a 63.5-gallon fluid capacity for sustained operational efficiency. Bucket options range from 0.7 to 1.1 cubic yards, with a reference capacity of 0.8 cubic yards, accommodating various material types. The 76.7-gallon fuel capacity supports extended working hours with minimal refueling interruptions. Additional features include a 14-degree oscillating axle angle for enhanced ground contact, 24-volt electrical system, and swing capability rated at 12.2 RPM, making this excavator suitable for construction, utility, and railway corridor applications.
