The big hydraulic excavators that deliver the demanded features - operator comfort, controllability, job efficiency, reliability, durability and safety. Thanks to Hitachi's advanced technology and years of experience, the EX550 and EX600H come equipped with many features. Their performance can be counted on when the going is tough.

The engine is designed to reduce pollutants (HC-hydrocarbons, CO-carbon monoxide and Nox-nitrogen oxides) is gas emissions for environmental protection, conforming to the Emission Stands in the USA and Japan.

With the increased radiator capacity and reduced cooling fan speed, air blowing noise is suppressed greatly.

Noise Levels:
75 dB(A) at operator's ear in cab
78 dB(A) at 7m (23'0") away

Wide-open engine covers gives specious inspection space, provifing direct access to the engine for easy maintenance.

The utility space, located behind the cab, is large enough for holding a spare grease can, pail can and tools.

The electric grease gun with hose reel is optionally available for easy greasing wihtout need for repositioning of the machine. Remote lubrication system is adopted for simple greasing for the front attachment and swing circle.

The track frames can be retracted for convenience of transport, and extended for increased stability at work. The LC type crawlers are increased in length for increased stability.
