HITACHI ZX850 CRAWLER EXCAVATOR

Technical Description

The Hitachi ZX850 is a robust hydraulic excavator engineered for heavy-duty construction and mining applications, representing the 85-ton class of equipment. This machine is powered by a turbocharged, 4-cycle water-cooled direct injection engine delivering 532 horsepower (397 kilowatts) at 1,800 RPM, providing substantial power for demanding excavation tasks. The excavator weighs 185,120 pounds (approximately 83,969 kilograms) in operating condition, making it a substantial piece of equipment designed for stability and durability in challenging work environments. The ZX850 excels in terms of digging capacity and reach, featuring a maximum digging depth of 31 feet (9 meters) and an impressive maximum digging reach of 48 feet (15 meters), enabling operators to access deep excavation points and distant material deposits. With a monobloc boom configuration and advanced hydraulic systems featuring high-strength piston rods and cylinder cushion mechanisms, the machine absorbs shock effectively during operation. The excavator's bucket capacity ranges up to 6.1 cubic meters, accommodating various attachment requirements for different jobsite conditions. The ZX850 incorporates modern operational features including a multi-function LCD monitor for real-time monitoring of maintenance intervals, fuel consumption, and work modes, enhancing operator efficiency and equipment management. The cab is ergonomically designed with adjustable armrests, retractable seat belts, and short stroke levers to minimize operator fatigue during extended operations. The machine includes a theft deterrent system requiring an encryption code for engine start, alongside day/night shift display adjustment capabilities, positioning the ZX850 as a sophisticated solution for professional excavation contractors.
