Hitachi develops tough wheel loader


Hitachi has announced the launch of wheel loader designed for the toughest of construction conditions.

Extensive research in Europe by the firm’s development team has led to the ZW330-6, featuring durable components and performance-enhancing technology to boost productivity.

Powered by a new Stage IV-compliant engine, the machine has 311hp at its disposal.

The traction force of the ZW330-6 has been improved by 26% for a more efficient loading operation compared with the previous model, the ZW-5. The new wheel loader also has a quick power switch that increases engine output when more power is instantly required, or when driving uphill.

Hitachi Construction Machinery (Europe) wheel loader product manager Vasilis Drougkas said, “The lift arm contributes to the reliable performance of the ZW330-6. It raises quicker than the ZW-5 model, stops smoothly thanks to the flow control system, and is easy to control using the auto leveller.

“Simultaneous movement of the lift arm and bucket ensures a smooth digging operation. The bucket is prioritized after unloading so that the wheel loader quickly returns to digging, helping to increase productivity.”

Fuel efficient
The lock-up transmission of the wheel loader reduces fuel consumption during traveling, which reduces running costs, also preventing energy loss in the torque converter by coupling the engine with the transmission.

To withstand working in tough environments, the ZW330-6 has been designed with a new rear grille that prevents material from the jobsite entering the radiator compartment. It is also equipped with high-quality radiators that offer improved resistance to corrosion.

A further example of its robustness is that the lift arm, and front and rear frame have been designed to handle the rigours of heavy applications. An optional belly guard provides added protection for the machine in challenging working conditions.
