The Hitachi ZW330-5 wheel loader has been designed to meet the requirements of European customers. It delivers a significant reduction in fuel consumption as well as excellent productivity, advanced technology, and a range of features for enhanced sustainability, comfort, safety and easy maintenance.
The ZW330-5 wheel loader complies with EU regulations on emission standards, but does not compromise on productivity. It has a 12.9-litre six-cylinder water-cooled turbo engine that enables a powerful digging performance, impressive travel speeds and a reduction in fuel consumption of more than 10%. The ZW-5 wheel loader is easier to manoeuvre than the previous model, which also results in higher levels of productivity. A clutch cut-off system controls the timing of the clutch for smooth operation when loading, regardless of the terrain. The model also benefits from a heavy-duty axle, renowned for high levels of performance and durability, making the ZW330-5 ideal for working on demanding job sites.
Two simple work modes provide an appropriate level of performance for a particular task. In Standard mode, the engine speed is controlled, which allows for smooth and efficient acceleration during loading, regular operations and travelling on level terrain. The P mode is useful when greater traction force is required for heavy-duty excavation and travelling quickly uphill.
When changing work modes, the ZW330-5 has a quick power switch, an example of its advanced technology, which boosts the power when required. The wheel loader also features a hydraulic circuit, which facilitates the combined operation of the bucket and lift arm for loading, and prioritises the use of the bucket for unloading.
The optional auto-engine shutdown function avoids fuel wastage while the wheel loaders are long idling. In addition to lowering fuel costs for the customer, this also enhances the sustainability of the ZW330-5. It also has a muffler filter to capture air pollutants, which are automatically burnt thanks to an oxidation catalyst and exhaust temperature control.
Comfort was a key factor in the design of the ZW330-5. The cab is more spacious than the previous model, because the heated air-suspension seat can slide further back, providing more legroom. The tilting telescopic pop-up steering column has also been repositioned to create additional space.
The air conditioning system regulates the temperature inside the cab, and an optional filter is available for dusty or industrial waste job sites. Sound insulation reduces noise levels from the local environment and improves the operator’s overall experience.
To enhance safety on the job site, the ZW330-5 offers greater visibility from the operator’s seat thanks to a pillar-less windshield and large sun visor. The counterweight is also visible from both sides of the machine. A multifunction LCD monitor with 7-inch screen displays the rear-view monitor and provides a wide range of technical information at a glance. The shift-up delay to third gear makes the wheel loader safer to operate in confined spaces, because it can perform excavating and unloading tasks more safely in first and second gear.
A variety of easy maintenance features have been incorporated into the design of the ZW330-5 to ensure maximum availability. For example, the redesigned engine and radiator cover can be opened fully, providing quick and convenient access for daily inspection. The greasing points, oil levels and fuel filters can all be accessed at ground level. It also has an automatic reversible cooling fan, which allows for easy cleaning of the radiator with its one-minute automatic reverse rotation every 30 operating minutes.
Vasilis Drougkas, Hitachi Construction Machinery (Europe) NV Product Specialist Wheel Loaders, says: “We believe that the ZW-5 wheel loaders not only meet our customers’ expectations of high quality and reliability, but also provide a safe working environment, a comfortable cab with easy-to-use controls, and overall, a machine that responds quickly and precisely.”
