HITACHI CONSTRUCTION MACHINERY

Following the successful launch of the ZX14-3 in 2008, Hitachi Construction Machinery (Europe) NV (HCME) has introduced two further new models to strengthen its range of mini excavators. The Japanese manufacturer has been at the forefront of the mini excavator market for two decades, and so the launch of the Hitachi ZX16-3 and ZX18-3 reinforces its commitment to this important sector of the construction industry.

Hitachi engineers have interpreted feedback from existing customers in conjunction with their extensive technical expertise to develop the new Zaxis models. The ZX16-3 and ZX18-3 are available with a cab or canopy, and are designed for light applications in confined spaces, such as utilities, gardening/landscaping and general purpose groundworks. They also provide better performance, ultimate comfort and safety, and benefit from reduced running costs.

HCME Assistant Manager Utility Products Joep van den Maagdenberg comments: “Every Hitachi mini excavator has been designed with durability, ease of maintenance and operator comfort in mind. The ZX16-3 and ZX18-3 are no exception. These new Zaxis models have already been tested extensively on a wide range of job sites. We are therefore confident that the enhanced performance of these machines will be well received by new and existing Hitachi owners, as well as rental customers.”

The Hitachi ZX16-3 and ZX18-3 are equipped with powerful and economical three-cylinder 10.7kW engines, which provide a significant increase in performance. Their superior power-to-weight ratios allow rapid acceleration and smooth operation in comparison with the previous models (ZX16 and ZX18).

The new Zaxis minis also have improved overall front speed and more precise handling capabilities, as well as an 18 per cent increase in digging force over their predecessors. The ZX18-3 has a more durable blade and an adjustable foot crawler for enhanced stability.

With operating weights of just 1,600kg and 1,770kg respectively, the ZX16-3 and ZX18-3’s lightweight characteristics enable them to be easily transported by trailer, driven under a standard EU driving license. This makes the machines ideal for transportation along narrow roads and helps to reduce logistical costs.

The Hitachi ZX16-3 and ZX18-3 have been designed with comfort and safety in mind. The wide opening door allows the operator to enter the spacious cab with ease. The canopy variants have a convenient walk-through design, which allows easy access to the controls from either side of the machine.

The fully adjustable fabric seat equipped with suspension absorbs vibrations during operation to reduce operator fatigue. In addition, the internal controls have been ergonomically designed and the speed selection switch has been placed on top of the blade lever grip for added comfort and convenience.

All ZX16-3 and ZX18-3 mini excavators can be fitted with an optional theft deterrent system, which requires the entry of a code to prevent illegal operation or vandalism. Other key features include the neutral engine start system and shut-off lever, which prevent accidental movements, and the single pin in the vertical swing post to minimise jerking.

Reduced running costs for the Hitachi ZX16-3 and ZX18-3 may be attributed to the use of highly durable components. The machines’ D-shaped frame provides additional reinforcement and helps to prevent damage caused by obstacles. The boom is reinforced with a strong, ribbed cylinder cover, which provides higher impact resistance. The counterweight also extends over both sides of the machine for further protection.

A new tread pattern has been applied to the rubber shoe for added durability. The short-pitch rubber crawler is also excellent in reducing vibration caused when traveling and its structure has been improved for stability.

With the engine cover open, parts such as the fuel and oil filters are easily accessible for quick servicing and inspection, therefore reducing operator downtime and maintenance costs. Side steel covers are easily detachable and repairable.

The easy-to-replace dustproof net also prevents foreign matter from entering the radiator and oil cooler, and causing damage to the machines’ internal components – avoiding unnecessary downtime. In addition, the ZX16-3 and ZX18-3 both benefit from a large 22-litre capacity fuel tank, which helps to increase productivity by working continuously without interruption.
