Hitachi Construction Machinery (Europe) NV (HCME) will present the new ZW250-5 wheel loader at Bauma. After listening to feedback from European customers, Hitachi has designed the new wheel loader to satisfy their requirements for machines that offer an exceptional level of comfort, as well as excellent productivity, advanced technology, and a range of features for enhanced sustainability, safety and easy maintenance.
The comfort of operators was one of the most important considerations for the design of the new ZW-5 wheel loader range. The cab is more spacious than the previous range, because the heated air-suspension seat can slide further back, providing more leg room. The tilting telescopic pop-up steering column has also been repositioned to create additional space.
An air conditioning system has been installed that regulates the temperature inside the cab, and an optional filter is available for industrial waste job sites. Sound insulation reduces noise levels from the local environment and improves the overall user experience.
The ZW250-5 wheel loader complies with EU regulations on emission standards, but does not compromise on productivity. It has a 7.8-litre six-cylinder water-cooled turbo engine that enables a powerful digging performance, impressive travel speeds and excellent fuel consumption.
The new ZW-5 wheel loader is easier to manoeuvre than the previous model, which also results in higher levels of productivity.
It has two simple work modes that 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. Fuel consumption is reduced by up to 10%, enhancing its environmentally friendly performance.
A new clutch cut-off system allows for smooth operation when it is loading.
Furthermore, the ZW250-5 has a quick power switch, an example of its advanced technology, which boosts the power when required by changing work modes.
A new hydraulic circuit also has a positive effect on efficiency because it 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 loader is long idling. In addition to lowering fuel costs for the customer, this also has the advantage of enhancing the sustainable operation of the wheel loader. A further example of its sustainability is the muffler filter – it captures air pollutants, which are automatically burnt thanks to an oxidation catalyst and exhaust temperature control.
To enhance safety on the job site, the ZW250-5 offers greater visibility from the operator’s seat thanks to a pillar-less windshield and large sun visor. The counterweight is also now visible from both sides of the machine. 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 ZW250-5 to ensure maximum availability wherever the ZW250-5 is working. 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.
For operation in dust-filled environments, the ZW250-5 wheel loader can be equipped with an optional wide-pitch fin radiator to prevent clogging. Another useful feature for quick routine maintenance is the automatic reversible cooling fan, which allows for easy cleaning of the radiator with its one-minute automatic reverse rotation every 30 operating minutes.
Nobuhiro Suzuki, HCME Engineer for wheel loaders, is looking forward to the reaction of the European market to the launch of the ZW250-5. “We believe that the new wheel loader not only meets our customers’ expectations of high quality and reliability, but also provides a safe working environment, a comfortable cab with easy-to-use controls, and overall, a machine that responds quickly and precisely.”
