HITACHI ZX450LC CRAWLER EXCAVATOR

Technical Description

The Hitachi ZX450LC is a heavy-duty hydraulic excavator engineered for demanding earthmoving and construction applications. Powered by a turbocharged AA-6WG1TQA engine producing 314 net horsepower at 1,800 rpm and generating 940.4 lb-ft of torque at 1,500 rpm, this machine delivers robust performance across diverse jobsites. The excavator features an operating weight of approximately 106,180 lbs and accommodates interchangeable bucket capacities ranging from 1.6 to 3.5 cubic yards, with a reference bucket of 2.8 cubic yards, providing operational flexibility for various material handling tasks. With multiple boom-and-stick configurations available, the ZX450LC achieves maximum digging depths from 18.8 to 33.6 feet, maximum cutting heights up to 40.2 feet, and maximum reach along ground extending to 46.9 feet, depending on the selected attachment option. The machine demonstrates a swing speed of 9 rpm with swing torque capability of 107,004 lb-ft, enabling efficient material positioning and placement. Ground pressure averages 11.1 psi with maximum travel speed of 3.5 mph, accommodating operation on soft and sensitive terrain. The hydraulic system incorporates two variable-displacement axial-piston pumps delivering 95.2 gpm maximum flow at 4,980 psi relief pressure, with total hydraulic fluid capacity of 134.8 gallons supporting continuous heavy-duty operation. Measuring 38.8 feet in shipping length and 11.1-11.5 feet in width, the ZX450LC balances transportability with substantial working capacity, making it suitable for quarrying, mining, demolition, and general construction applications requiring precision excavation and material movement capabilities.
