Komatsu’s automatic excavator
Machine control automates bucket dig depth
Komatsu has launched a new excavator with factory fitted machine control, heralding it as a world first. The PC210LCi-10 excavator, launched in Europe, has a Komatsu machine control and guidance system that is integrated with the features of a standard PC210LC-10.
“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 machine control. “The ability of the PC210LCi-10 to achieve and maintain grade with minimum effort from the operator is awesome”.
Machine control features means that the bucket will automatically not dig beneath a target surface, allowing the operator to quickly dig a trench or hole without fear of the bucket teeth going below or damaging the surface.
The machine control system uses integrated stroke sensing on the hydraulic cylinders to measure the boom, arm and bucket position. An IMU (Inertial Measuring Unit) gives precise machine orientation and determines machine angle from gyro and accelerometer data, while its antennae send satellite signals to a GNSS receiver that processes them and provides real time position of the machine.
The 3D design data is set on the control box monitor in the cabin, which displays information icluding a facing angle compass, a light bar, a real-time “as-built” status and a magnified fine grading view, or a 3D bird view. Use of machine control eliminates the need for staking or extra grade checking, reducing the number of staff needed, and improving safety with the checker not having to climb into the hole to measure depth.
Overall, cycle times and operator performance are improved with a reduced risk of error, and lower costs for fuel, labour and machine utilisation, said McCoy.
