Technical Description

The Hitachi ZX450LC-3 is a heavy-duty hydraulic excavator engineered for demanding earthmoving and excavation applications. Powered by a turbocharged Isuzu engine, this machine delivers 348 SAE net horsepower at 1,800 rpm with maximum torque of 1,164 lb-ft at 1,500 rpm, providing substantial digging force across varied job sites. The unit weighs approximately 106,180 pounds operating weight and features a 3.06 cubic yard backhoe bucket with a 54-inch width, accommodating diverse material handling tasks. Dimensionally, the ZX450LC-3 boasts multiple boom and stick configurations offering maximum reach capabilities from 33.9 to 47.1 feet along the ground and cutting heights ranging from 33.7 to 40.2 feet depending on configuration selection. Maximum digging depths extend from 19.4 to 33.6 feet, with vertical wall digging depths reaching up to 30.9 feet on extended boom options. The machine maintains a compact ground footprint with an 11.46-foot width and 14.67-foot track length, facilitating access to confined work areas. The hydraulic system features dual variable-displacement axial-piston pumps delivering 200 gallons per minute combined flow at system operating pressures reaching 4,980 psi for travel circuits. Ground pressure averages 8.81 psi with triple semi-grouser shoes, minimizing surface damage on sensitive terrain. With a swing speed of nine rpm and drawbar pull of 79,590 pounds, the excavator provides responsive operation and powerful traction. The 192-gallon fuel tank and advanced cooling system ensure extended operational periods, making the ZX450LC-3 a versatile solution for mining, construction, and heavy material handling operations.
