HITACHI ZX350LCK CRAWLER EXCAVATOR

Technical Description

The Hitachi ZX350LCK is a medium-to-large hydraulic excavator engineered for demanding construction and excavation applications. Powered by an Isuzu AA-6HK1X turbocharged, intercooled diesel engine, this machine delivers 247 horsepower at 2000 rpm with a maximum torque output of 643.9 foot-pounds at 1700 rpm. The engine features a 475.4 cubic-inch displacement and operates on a 24-volt electrical system supplied by a 50-amp alternator. With an operating weight of approximately 57,982 pounds and a track gauge of 8.5 feet, the ZX350LCK achieves a ground pressure of 9.2 psi, facilitating operation on soft ground conditions. The machine reaches a maximum digging depth of 24.3 feet and a maximum reach along ground of 35.8 feet, with a cutting height capability of 33.6 feet. The hydraulic system maintains a 153.3 gallons-per-minute pump flow capacity at a 5050 psi relief pressure, with an 84.6-gallon fluid capacity for sustained operation. The excavator accommodates bucket capacities ranging from 1.9 to 2.2 cubic yards, providing versatility for various material handling tasks. Its boom and stick configuration options, combined with a tail swing radius of 10.9 feet and maximum travel speed of 3.5 mph, enable efficient job-site maneuverability. The comprehensive cooling and lubrication systems include 9.3 gallons for engine coolant and 9.6 gallons for engine oil capacity, ensuring reliable thermal management during extended operational cycles. This configuration represents a balanced solution for mid-range earthmoving operations requiring precision and power.
