Zaxis Mini-Excavator Range Expands - Construction International

Close Move

The arrival of the new Hitachi Zaxis short-tail mini-excavator began in 2005 with the introduction of the ZX30U-2. This compact machine has already proved a popular extension to the range throughout Europe.

Hitachi is now expanding its line-up in this category with the launch of the ZX10U-2, ZX17U-2 and ZX22U-2. The new models will be unveiled to the public for the first time at Bauma.

The use of mini-excavators has traditionally been the solution for confined spaces. However, the development of short and zero tail-swing excavators has provided an alternative option in such restricted working conditions.

Hitachi engineers have used their vast experience and expertise to develop the ZaxisU-2 models, which combine the best of both product lines in one versatile package.

The series has been fitted with powerful - yet economical - and durable engines to maximise productivity on any job site. The new engines have been fitted with larger exhaust capacities to meet the latest emission regulations and noise suppression and ROPS/FOPS standards.

Each model has been designed with stability, durability, ease of maintenance, and operator comfort in mind.

Stability

Hitachi has designed the new ZaxisU-2 models with a number of stability-enhancing features. Each of these helps to improve on-site safety.

Features	Benefits
Standard additional counterweight when operated with heavy attachment Automatic travel speed - control at high speed	Minimised compromise between tail swing and stability Automatically adjusting travel speeds

Operator comfort

Like all new Zaxis machines, the safety and comfort of the operator have been prioritised and contribute to the user-friendliness of the ZaxisU-2 excavators.

Features	Benefits
Roof sun visor Ample leg room and foot space Air conditioning Folding seat Neutral engine start system Lock-lever Easy to read monitor Rubber mounted floor	Enhanced visibility Comfortable and variable interior working conditions Allows operator to easily shut off the front swing and travelling mode Neutral engine starting option Enhanced feeling of control Facility to check fuel levels, coolant temperatures and other indicators Improved resistance to shocks

Maintenance

The ZaxisU-2 series adopts the benefits associated with the larger excavators in the Hitachi range. These include unshakeable reliability and low and easy maintenance.

Features	Benefits
All major inspection points within easy reach Wide opening engine cover Hitachi-developed rubber crawlers	Allows easy cleaning of components Increased durability Ultimate reliability

Durability

All of the ZaxisU-2 models have been built to provide improved durability. Many innovative features have been introduced to help enhance residual value.
