Hitachi Construction Machinery will showcase a wide range of products and services at bauma 2019, including several new Zaxis-6 mini excavators (ZX17U-6 to ZX85USB-6), compact wheel loaders (ZW75-6 and ZW95-6), the ZX210X-6 ICT hydraulic excavator, and new special application machines.
Included in the Hitachi line-up is the new ZX210LC-6 super long front excavator, the ZX135US-6 with telescopic arm, and ZX135US-6 with sliding arm. These are the some of the smaller models in the special application range of Hitachi construction machinery, factory-modified to meet the demands of specific activities, such as slope finishing and deep excavation.
Hitachi’s first ICT hydraulic excavator with machine control in Europe, the ZX210X-6, can complete excavation tasks 50% faster than a standard excavator, facilitated by the semi-automatic operation of the boom and arm.
One of the features that enables the ZX210X-6 to work quicker than conventional models is the bucket angle retention. Slope finishing can be carried out with fewer movements, for example, as the angle of the bucket is maintained throughout. This also allows the operator to focus on the operation of the boom and arm.
Another feature is the overcut protection function, which enables operators to work quickly and easily, without worrying about over digging. The edge of the bucket is controlled by the ZX210X-6, so that it follows the target surface.
The sensors mounted on the body, boom, arm and bucket of the ZX210X-6 enable accurate measurement of the excavator’s incline, and the angle of the front of the machine. They work in harmony with the hydraulic control unit.
The accurate position of the ZX210X-6 can be determined with the 3D system. 3D civil engineering design data can be downloaded by the machine via the internet or a USB device, and its position and altitude are then ascertained by satellite positioning and the sensors.
Alternatively, the 2D system uses coordinates, calculated from design drawings, and data entered manually by the operator into the monitor. It uses the machine as a reference point, taking information from the sensors. Some staking is required for measuring on site when using the 2D system, whereas this is significantly reduced using 3D.
The 10-inch touchscreen monitor in the cab of the ZX210X-6, developed in cooperation with Trimble, is factory-fitted by Hitachi Construction Machinery and operates like a smartphone.
The operator can rotate the view of the machine 360°, and also zoom in and out of the view to monitor progress in more detail. The view can be customised according the operator’s preference, and it has a split-screen option to show two or three views simultaneously.
The introduction of the ZX210X-6 machine to the European market is a significant in the wider context of its development of ICT construction solutions and the increasing importance of BIM (building information modelling) in the construction industry.
