Efficient hydraulics

Hitachi’s computer-aided Engine-Pump Control produces optimum efficiency from the engine and hydraulic pumps. This innovative system senses load demand and controls the engine and pump output for maximum operating efficiency.

Solid construction

Computer-assisted analysis is used to ensure the frame box can withstand heavy-duty excavation work. The machine’s track frame, which is used exclusively on large Hitachi models, is cast as a solid unit and includes a flange for improved reliability. Our shoes include roller guides for extended service life.

Flow-assist system

Using the meter-in valves, ample-capacity make-up valves, and flow-assisting pumps, the flow speed is increased in cylinders for dynamic actions. This is especially relevant between dumping and digging. The result is a short cycle time, not much longer than the smaller EX5500-6.

Lower rollers, track links and drive tumblers

The EX8000-6 features newly designed rugged lower rollers, track links and drive tumblers to sustain the excavator’s giant body for assets/increased durability and serviceability.

Ergonomically designed cab

You’ll love the cab for the EX8000-6.The ergonomic layout means you’ll do less stretching and reaching. The roomier seat and cab will make you feel comfortable and well supported, with plenty of leg room. And the high height and forward-sloping cab provides a view that boosts productivity. The cab is pressurized to keep out dust while maintaining a comfortable temperature.

Cab utility space

With an expansive cab area, you’ll have plenty of utility space behind the operator’s seat and training seat to hold a table, microwave and refrigerator. This allows for a full 24-hour-a-day operation for higher productivity.
