Hitachi Construction Machinery Australia recently announced the launch of the new Zaxis-5 mini excavator range, which it claims offer customers increased productivity and less fuel consumption.
There are five models in the range: ZX33U-5, ZX38U-5, ZX48U-5, ZX55U-5 and ZX65USB-5.
Hitachi says the Zaxis-5 excavators extends on the success of the predecessor model and features a number of customer inspired upgrades as well as new features.
The new range features Hitachi’s renowned compact swing radius and precise movement which Hitachi says will allow smooth, quick and responsive controllability in complex and challenging applications.
Factory standard hose rupture valves have been integrated in all mini excavator models to further enhance machine safety. The new excavators also feature a strengthened frame structure, designed for enhanced safety and greater machine durability.
Hitachi claims productivity has been increased by an average of 2.75 per cent across four of the new models and also an 11.5 per cent reduction in fuel consumption for some of the machines in the new range.
Like other Hitachi excavators, power-mode and eco-mode have been incorporated into the new mini-excavators, which Hitachi says is optimised for both performance and improved fuel efficiency.
Hitachi says the eco-mode selection gives operators the benefit of not only increasing efficiency by reducing the speed of the front attachment, but it also maintains a similar level of performance to conventional models on power mode.
The excavators also come with a newer; more energy efficient engine which Hitachi says will lead to a reduction in both fuel consumption and noise levels by suppressing excessive engine RPMs during light operations.
The stack muffler specification provides very low noise levels and reduces exhaust gas pollutants.
Auto idle comes standard, preventing unnecessary fuel consumption and exhaust gas emissions when the excavator is idling.
The intelligent transmission system in the new excavators automatically shifts between high and low according to load, particularly when moving from a flat surface to a slope where the transmission shifts to low for smooth climbing. Travel speeds can also be switched during blade operations.
The distance between the blade and the bucket has also been reduced to enhance front blade operations, such as asphalt removal.
Hitachi has also increased the total workspace of the new range to create a more comfortable and spacious operator environment for the user. The front windshield is larger and provides a wider field of vision for the operator. A newly designed multi-function monitor system displays information such as machine diagnostics, settings and warnings.
Hitachi says accessibility and serviceability have been improved for the new models. The oil cooler and radiator are conveniently positioned, with a newly designed cooler core and rounded frame structure helping to reduce material build-up thus making cleaning easy.
Machine inspection and maintenance was also made easier with engine covers that slide out of the way.
