HITACHI ZX330 CRAWLER EXCAVATOR

Technical Description

The Hitachi ZX330 is a mid-sized hydraulic crawler excavator engineered for demanding earthmoving and construction applications. Powered by a turbocharged, intercooled Isuzu six-cylinder diesel engine displacing 475.4 cubic inches, the machine delivers 247 net horsepower at 2000 rpm and maximum torque of 643.9 foot-pounds at 1700 rpm. The excavator features a robust two-pump hydraulic system with dual variable displacement axial piston pumps providing 153.3 gallons per minute of flow at a maximum relief pressure of 5050 psi, enabling powerful digging and loading operations. With an operating weight of 73,500 pounds, the ZX330 maintains exceptional maneuverability through its tractor-type undercarriage equipped with reinforced tracks featuring 45 shoes per side and dual carrier rollers. Ground pressure of just 9.2 psi minimizes ground impact for sensitive terrain. The machine accommodates three boom and arm configurations, achieving maximum digging depths ranging from 22.5 to 26.9 feet and horizontal reaches extending to 38.4 feet along ground level. Bucket capacity options span 1.2 to 2.2 cubic yards, accommodating various material handling requirements. The cab design prioritizes operator comfort and safety with adjustable armrests, retractable seatbelts, and short-stroke control levers reducing fatigue during extended operations. Key specifications include a 10.3-foot cab height, 10.5-foot track width, and minimal ground clearance of 1.7 feet. Maximum travel speed reaches 3.5 mph in high gear, while the swing mechanism rotates at 11.8 rpm. The 148-gallon fuel capacity and comprehensive 84.6-gallon hydraulic reservoir support extended operational periods, making the ZX330 an efficient, versatile solution for excavation, material handling, and site development projects.
