Hitachi Compact Excavator Digs More Yards Per Hour

Wed September 27, 2006 - National Edition
CEG



The Zaxis 27u-2 compact excavator is ideally suited to a wide variety of applications.

Productivity receives a boost from numerous improvements, including increased operating speeds, 50 percent more drawbar pull and automatic shifting between high and low travel speeds.

Cycle times have been cut by 18 percent, allowing operators to dig more cubic yards per hour.

A long arm/counterweight option adds approximately 12 in. (30.5 cm) of dig depth and reach.

Powered by a Yanmar 3TNV88 engine, the 27u-2 engine displacement has increased from 1.496 L to 1.642 L. This engine also features a higher torque curve.

The operator’s station provides significant improvements that greatly enhance operator comfort.

The cab is 5 in. (12.7 cm) wider and both hand and foot control levers have been better positioned for easier operation and more room.

Foot room also has increased due to relocation of the speed selector switch and new foldable travel pedals.

The repositioned monitor provides better visibility. The cab door now features a bi-fold design that allows the operator to lock it back against the cab in the open position.

Factory-installed air conditioning is standard when the optional ROPS cab is ordered. A cup holder also is standard.

Several features enhance uptime in this machine such as an updated undercarriage that sheds dirt easily and reduces the time it takes to clean the machine.

Improved rubber tracks are harder and have a reshaped core to resist cracking.

The drive sprocket and track idler have increased in diameter.

The boom cylinder guard has reinforcement ribs that improve strength and reduce the likelihood of cylinder damage.

Front hoses in the swing post transition area can quickly be replaced without tilting the cab or routing the hoses to the control valve.

The Zaxis 27u-2 has been designed to be easily serviced and maintained. The operator station tilts forward 50 degrees for easy access to the control valve and front side engine components.

All service checks can be performed by opening just two covers. In addition, extended service intervals save both time and money, with a 500-hour interval for engine oil change and greasing, and 2,000-hour interval for hydraulic oil change.
