Komatsu’s 3D semi-automatic excavator
May 25, 2016 By Andrew Macklin
May 25, 2016 – Komatsu America Corp. introduced the new PC490LCi-11 hydraulic excavator, the largest 3D semi-automatic construction-sized excavator available.
Intelligent Machine Control features a unique sensor package, including stroke sensing hydraulic cylinders, an IMU sensor, and GNSS antennas. The machine utilizes 3D design data loaded into the machine’s monitor to accurately display machine position relative to target grade. When the bucket reaches the target surface, automation kicks in to limit over excavation.
Features that make the PC490LCi-11 a game-changing hydraulic excavator include:
- Auto Grade Assist – as the operator moves the arm, the boom adjusts the bucket height automatically, tracing the target surface and minimizing digging too deep.
- Auto Stop Control – during boom and bucket operation, the work equipment automatically stops when the bucket edge reaches the design surface, thus minimizing design surface damage.
- Minimum Distance Control – the machine controls the bucket by automatically selecting the point on the bucket closest to the target surface. If the machine is not facing a sloped surface at a right angle, it will still follow the target surface and minimize digging below it.
- Facing Angle Compass – the orientation of the facing angle compass’ arrow shows the operator the facing angle, relative to target surface. This allows the bucket edge to be accurately positioned square with the target surface.
- Realistic 3D Display – the machine and design surfaces are shown in realistic 3D. The angle and magnification of the views can be changed, allowing the operator to select the optimum view, depending on work conditions.
- Control Box – the Intelligent Machine Control monitor uses a large 12.1 screen for visibility and ease of use. The simple screen layout displays the necessary information in an easily understood fashion. A touch screen icon interface, instead of a multi-step menu, simplifies operation.
Other performance features include:
- A 11.04 litre, 359 horsepower, EPA Tier 4 Final, SAA6D125E-7 engine
- An up to 13 per cent productivity improvement, thanks to increased hydraulic flow in Power Mode
- Up to seven per cent more arm crowd force and bucket digging force, respectively, when the one-touch, Power Max function is engaged
- KOMTRAX level 5 technology feeds the operator machine data, such as fuel and diesel exhaust fluid (DEF) levels, Komatsu Diesel Particulate Filter (DPF), regeneration status, location, cautions and maintenance alert information.
The PC490LCi-11 excavator, whether rented, leased or purchased, is covered by the Komatsu CARE program for the first three years or 2000 hours, whichever comes first.
