HITACHI ZX140W-3 CRAWLER EXCAVATOR

Technical Description

The Hitachi ZX140W-3 is a versatile wheeled excavator engineered for demanding construction and excavation applications. Powered by a turbocharged, intercooled Isuzu AI-4JJ1X diesel engine, this machine delivers 121 horsepower and 90.2 kilowatts at 2200 rpm, with maximum torque of 296.5 foot-pounds at 1800 rpm. The excavator features an operating weight ranging from 14,700 to 16,000 kilograms and accommodates bucket capacities from 0.3 to 0.9 cubic yards depending on application requirements. The machine offers three boom/stick configurations to optimize performance for various job sites. Option One achieves a maximum digging depth of 15.2 feet and reach of 25.8 feet, while Option Three extends capabilities to 18.2 feet digging depth and 28.6 feet reach with a maximum cutting height of 30.1 feet. The hydraulic system utilizes two variable displacement axial piston pumps with 83.3 gallons-per-minute flow capacity and 4974.8 psi relief pressure, ensuring responsive control and efficient power delivery. Mobility is facilitated through a 2-speed power shift transmission paired with a variable displacement axial piston travel motor, enabling maximum travel speeds of 21.8 miles per hour. The swing mechanism rotates at 13.7 rpm, while the oscillating axle angle of 14 degrees provides stability across uneven terrain. With a fuel capacity of 66.1 gallons and comprehensive hydraulic system capacity of 47.6 gallons, the ZX140W-3 demonstrates excellent operational endurance suitable for full-day excavation projects.
