HITACHI ZX225US-3 CRAWLER EXCAVATOR

Technical Description

The Hitachi ZX225US-3 is a compact hydraulic excavator engineered for demanding construction and earthmoving applications. Powered by a turbocharged and intercooled AI-4HK1X diesel engine, this machine delivers 164 horsepower (122 kW) at 2,000 rpm with maximum torque output of 483.2 lb-ft at 1,500 rpm, providing efficient power for sustained productivity. The excavator features an operating weight of 51,147 pounds and operates on a 24-volt electrical system supported by a 50-amp alternator. With its short-tail-swing design and 5.6-foot tail swing radius, the ZX225US-3 excels in confined worksites where space limitations are critical. The machine accommodates variable bucket capacities ranging from 0.7 to 1.6 cubic yards, with a reference bucket of 1.1 cubic yards. Depending on boom and stick configuration, maximum digging depth reaches either 20.4 or 22 feet, with corresponding maximum reach along ground of 30.6 or 32.3 feet respectively. The hydraulic system delivers 112.1 gallons per minute through a pump operating at 4,974.8 psi relief pressure, with 60.8 gallons of system fluid capacity. The undercarriage incorporates advanced low-ground-pressure technology, generating just 7.6 psi through 23.7-inch shoes with 46 shoes per side. Swing mechanism operates at 13.3 rpm with substantial torque for precise positioning. Travel speeds reach 3.5 mph maximum, while the cab provides climate control and an operator-focused ergonomic design suitable for extended work shifts in demanding conditions.
