HITACHI ZX270-3 CRAWLER EXCAVATOR

The Hitachi ZX270-3 excavator is a robust hydraulic machine engineered for heavy-duty excavation tasks, with an operating weight of 27,300 lbs (approximately 12,388 kg). Powered by the Isuzu AH-4HK1X turbocharged and intercooled engine, it delivers a net power output of 188 hp (140 kW) and a maximum torque of 69 lb-ft, ensuring efficient performance across demanding terrains. The engine displacement measures 316.9 cubic inches, supporting a fuel capacity of 132.5 gallons, enabling extended operation durations without frequent refueling. Cooling is managed by a fluid system holding 98 gallons and a separate 6-gallon engine oil capacity to maintain optimal thermal regulation and engine health. The hydraulic system features a flow capacity of 34 gallons per minute with a total fluid capacity of 76.8 gallons, permitting strong and responsive boom and arm movements. Its swing mechanism operates at 12.6 rpm, supplied with 3 gallons of swing drive fluid to smoothly rotate the upper structure for precise positioning. The excavator runs on a 24-volt electrical system with an 88-amp alternator to support onboard electrical components. The undercarriage includes 45 track shoes per side with 7 track rollers and 2 carrier rollers each, accommodating a shoe size of 23.7 inches and supporting a drawbar pull capacity of 55,303 lbs. The ground pressure stands at 8 psi, aiding stability and minimizing surface impact. The maximum travel speed is 3.5 mph (5 kph), making it suitable for various job site mobilities. This combination of power, hydraulic efficiency, and stable undercarriage design makes the Hitachi ZX270-3 a versatile choice for excavation projects requiring reliability and precision.
