Since its introduction the success of the Komatsu excavator intelligent Machine Control system in delivering step changes in productivity, efficiency and cost saving for customers’ businesses has led to it being recognised as the benchmark technology in the construction industry. With the introduction of the PC360LCi-11, customers can now experience those benefits on large infrastructure and earthmoving projects.

“Since we introduced the PC210LCi-11, customers have seen the opportunities of using of our intelligent Machine Control technology on jobs that require higher volume excavation, and many have been asking for a larger machine to deliver those benefits,” says Rob Macintyre, Product Manager at Komatsu Europe. “In launching the new PC360LCi-11 we are responding to that customer demand, and we see huge potential for it to realise major productivity, efficiency and cost saving gains in these types of applications.”

Operating weights of the PC360LCi-11 range from 35.600 – 36.200 kg, depending on the configuration, and it has a maximum recommended bucket capacity of 2.66m³. The fuel efficient, EU Stage IV Komatsu SAA6D114E-6 engine puts out a net 192 kW / 257 HP @ 1.950 rpm.

The latest KOMTRAX telematics, and the Komatsu Care maintenance program for customers, offer top fleet management and support, protect the machine against misuse and guarantee maximum efficiency and uptime.

Innovative: Automatic Real Time Digging Control

With Komatsu’s unique intelligent Machine Control, the bucket is automatically limited from digging beyond the target surface. The control function maintains grade automatically, with real-time bucket edge positioning in relation to the machine and the job surface. Status is instantly displayed on the full colour, multi-function 12.1” control box monitor, eliminating the wait time associated with conventional sensors.

Integrated: Standard Factory- Installed Integrated Machine Control System

Fully factory-installed, Komatsu’s integrated intelligent Machine Control system includes stroke sensing hydraulic cylinders for the boom, arm and bucket, developed over two machine generations by Komatsu for precise real time bucket edge positioning. The IMU (Inertial Measuring Unit) gives provides machine orientation and determines machine angle from gyro and accelerometer data. High performance antennae send satellite signals to a GNSS receiver that processes them and provides real time position of the machine.

Intelligent: Enhancements for Optimized Performance

The Komatsu PC360LCi-11 intelligent Machine Control excavator lets the operator focus on moving material efficiently without worrying about digging too deep. The touch screen control box monitor, makes grading easy and accurate, providing the operator with real time information on bucket edge position in relation to design surface, “as-built” status, and customisable spilt screen views in profile, plan or 3D format.

By setting 3D design data on the control box monitor, the use of traditional guidance methods such as stakes and grade rails can be reduced or eliminated, as can surveying and final inspection. Safety is greatly improved, with less people needed on the job site and near the machine.

Intelligent ON/OFF switches for the semi-automatic function, and raise/lower of the design offset, are fully integrated in the joysticks. This further increases efficiency and safety for the operator.

Benefits

The unique benefits of the new Komatsu PC360LCi-11 combine the high productivity of a bulk earthmoving excavator with the renowned accuracy of Komatsu intelligent Machine Control. This is achieved by powerful hydraulics and breakout forces when excavating, fast cycle times when truck loading, and by completing grading automatically in just one pass. Fewer machine cycles are required and operator performance is improved, with vastly reduced risk of re-work, lower fuel costs and increased machine utilisation.

Incorporating the latest technological advancements from Hitachi Construction Machinery, the ZX210X-6 excavator is one of the most precise models on the market. The semi-automatic operation of the front of the machine ensures consistently high levels of accuracy. As a result, the amount of repetitive work on site is decreased and less time is needed to complete construction projects – leading to reduced running costs and fewer emissions.

The ZX210X-6’s highly accurate performance also contributes to enhanced safety on the job site. Designed for easy operation with user-friendly features, it supports the skills of operators.

Exceptional efficiency

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.

Unrivalled accuracy

The responsive sensors mounted on the body, boom, arm and bucket of the ZX210X-6 are among the fastest available. These enable accurate measurement of the excavator’s incline, and the angle of the front of the machine. They work in perfect harmony with the unique hydraulic control unit. When combined with the renowned hydraulics of Hitachi excavators, this gives the ZX210X-6 a competitive edge in the market.

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.

User-friendly operation

The easy-to-read 10-inch touchscreen monitor in the cab of the ZX210X-6 highlights its user-friendly appeal. Developed in cooperation with one of the global leaders of machine guidance devices, Trimble, it 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 milestone for Hitachi Construction Machinery, in the wider context of its development of ICT construction solutions and the increasing importance of BIM (building information modelling) in the construction industry.

Hitachi Construction Machinery (Europe) NV Product Manager Wilbert Blom says: “The ZX210X-6 excavator plays a pivotal role in Hitachi’s ICT construction solutions, which connect people, information, processes and technology to create safe and productive working environments. More accurate than its competitors, it is the most technologically advanced Hitachi excavator to date.”
