HITACHI ZX210W CRAWLER EXCAVATOR

Technical Description

The Hitachi ZX210W is a versatile wheeled mobile excavator designed for medium to heavy-duty construction applications. Powered by a turbocharged, intercooled six-cylinder Isuzu engine, it delivers 147 horsepower and 110 kilowatts of rated power at 2,100 rpm, with maximum torque of 405.7 foot-pounds at 1,600 rpm. The machine operates at an impressive 89.9-gallon fuel capacity, supported by a robust hydraulic system featuring two variable displacement axial piston pumps delivering 113.1 gallons per minute at a relief valve pressure of 4,980 psi. Available in two boom and stick configurations, the ZX210W offers exceptional reach and digging capabilities. Option one achieves a maximum cutting height of 31 feet and digging depth of 18.8 feet, while option two extends these capabilities to 32.4 feet and 21.1 feet respectively, with ground reaches up to 32.7 feet. The compact wheeled design features a wheelbase of 9.1 feet and tail swing radius of 8.9 feet, enabling maneuverability in confined spaces. With an overall width of 8.3 inches and ground clearance of 1.2 feet, the excavator maintains excellent operational stability. The transmission system employs a two-speed power-shift mechanism with dual forward and reverse gears, enabling maximum travel speeds of 15.6 miles per hour. The swing mechanism rotates at 13.6 rpm with significant torque capacity. Operating weight ranges from 20,100 to 21,600 kilograms, depending on configuration, while bucket capacity spans 0.52 to 0.91 cubic meters. Enhanced hydraulic boost systems and optimized engine efficiency reduce fuel consumption during extended operations.
