The engine and radiator covers of Hitachi’s three new mini excavators have been redesigned to allow easy access
Said to be user-friendly, offering high levels of performance, comfort and durability, the new Zaxis-5 models are ideal for working in narrow or confined spaces.
The ZX17U-5 and ZX19U-5 are claimed by Hitachi to be more productive than other brands of mini excavators of this size. Due to their greater hydraulic efficiency, they are also said to be more productive than previous Zaxis models, using the same amount of fuel. The same high hydraulic efficiency is also said to ensure that the ZX26U-5 is more productive than previous Zaxis models of the same size, with the same fuel usage.
The versatility of the new ZX17U-5 and ZX19U-5 is highlighted by the expandable crawler tracks. They can be retracted or widened – depending on the requirements of the job site – from 98cm, for working in small spaces or being loaded on to a truck, to 128cm for greater stability.
Meanwhile, the extra piping and 1-2 way selector valve highlight the ZX26U-5’s versatility, allowing for the quick replacement of attachments. The model is also said to have the smallest front swing radius (at fully offset) in its class, making it ideal for working in tight job sites.
Several new and improved features have been incorporated into the ZX17U-5, ZX19U-5 and ZX26U-5 to enhance their durability. The front of each machine, for example, is fitted with a boom cylinder guard and has a new V-shaped boom cylinder cover with two bolts for added durability.
On the ZX17U-5 and ZX19U-5 models, the rubber crawlers have been upgraded and the undercover of the revolving platform frame has been lengthened. Hitachi says that the design of both models has changed to a D-frame for extra durability.
On the ZX26U-5 mini excavator, the double clamps on the piping is said to have increased the reliability of the piping connection and minimised oil leaks.
