HITACHI ZX270 CRAWLER EXCAVATOR

Technical Description

The Hitachi ZX270 is a robust mid-size hydraulic excavator engineered for demanding earthmoving and construction applications. Powered by a turbocharged, intercooled AA-6BGIT diesel engine with 396.3 cubic inches of displacement, this machine delivers 173 horsepower at 2,150 rpm and produces 469.9 foot-pounds of torque at 1,800 rpm, providing reliable performance across varied job sites. The excavator operates at 24 volts with a 50-amp alternator and maintains a 100.4-gallon fuel capacity for extended operational periods. The ZX270 features three configurable boom-and-stick combinations, accommodating diverse working requirements. Option 1 achieves a maximum cutting height of 31.7 feet and digging depth of 21.5 feet. Option 2 extends capabilities with a 32.8-foot cutting height and 23.8-foot digging depth, while Option 3 maximizes reach at 33.4 feet cutting height and 25.9-foot digging depth, with horizontal reach extending to 36.4 feet. Bucket capacity ranges from 1.1 to 1.9 cubic yards, with a reference capacity of 1.5 cubic yards. Weighing 59,524.9 pounds, the ZX270 maintains an extremely low ground pressure of 8 psi, enabling operation on sensitive terrain. Its compact footprint—10.5 feet wide, 10.3 feet tall to cab, and 12.3 feet track length—facilitates access to confined spaces. The hydraulic system circulates 110.5 gallons per minute at 5,050 psi relief pressure through 81.2 gallons of system fluid, while the swing mechanism rotates at 10.6 rpm. Maximum travel speed reaches 3.1 mph with a 9.7-foot tail swing radius, making this excavator suitable for precision excavation, foundation work, and utility trenching.
