Smart digging - Komatsu's intelligent control
By Lindsay Gale05 August 2014
Komatsu Europe International has launched a new version of its PC210LC-10, the PC210LCi-10, that is fitted with what the company says is the world’s first machine control and guidance system that is fully integrated with all the other features of the standard machine.
Operating weights of the new excavator range from 22.6 to 23.5 tonnes, depending on configuration, and it offers 123 kW (165 hp) at 2,000 rpm. The machine’s other specifications are identical to the standard PC210LC-10.
The intelligent control system ensures that the bucket is automatically limited from digging beyond the target surface. It maintains grade automatically, with real-time bucket edge positioning in relation to the machine and the work surface. Status is instantly displayed on the full colour, multi-function control box monitor, eliminating the wait time associated with conventional sensors.
The system includes stroke sensing hydraulic cylinders for the boom, arm and bucket. The Inertial Measuring Unit (IMU) gives precise machine orientation and determines machine angle from gyro and accelerometer data. High performance antennae send satellite signals to a GNSS receiver that processes them to provide real time machine position.
“This latest Komatsu technology is a revolution in how hydraulic excavators will be used in the coming years” said Mal McCoy, product manager for hydraulic excavators and intelligent machine control products. “The ability of the PC210LCi-10 to achieve and maintain grade with minimum effort from the operator is awesome."
