Productivity is the driving force behind Komatsu’s intelligent Machine Control (iMC) technology, an integrated system for dozers and excavators that enables precision digging or grading work. This system eliminates the need for surveying equipment and pre-calculated terrain layout references prior to execution of the work. Global Navigation Satellite System (GNSS) technology guides the equipment operator in grading, sloping and laying out complex jobsite terrain.

The navigation system is integrated into the machine, meaning that the GNSS and radio antennas are mounted on top of the operator’s cab, away from jobsite hazards and free from exposed cables. The radio antenna enables the transmission of jobsite coordinates between the dozer and the base station, via UHF or 915 radio signals.

Stroke sensors are mounted to the cylinders that control blade position on iMC equipment. These stroke sensors also incorporate a reset sensor, which calibrates cylinder position on the cylinder retraction stroke. The sensors allow computer-controlled blade positioning to maintain precise grade control, thus enabling faster grading operations. This technology results in more efficient machine use with less rework, which, in turn, lowers machine operating costs.

The Inertial Measurement Unit (IMU) is mounted beneath the floor plate and measures 3-D positioning (X lateral, Y longitudinal and the Z vertical positions) of the machine on the jobsite terrain. It also detects movement in all three dimensions (roll, pitch and yaw) and the acceleration of the dozer to provide the most stable and responsive control system possible. The IMU ensures fine grading at high speeds with precise accuracy. Working with the machine’s sensors, computers and positioning controls, cutting-edge adjustments are completed 10 times faster than conventional systems.
