Komatsu has extended its PXi crawler dozers range with three new models 37PXi, 39PXi and 51Pxi to join D61PXi-23. The D61PXi-23 is powered by an engine with capacity of 168 hp and 37PXi, 39PXi and 51PXi - 89 hp, 105 hp and 130 hp respectively. All the new crawler dozers feature automatic blade control.
When rough dozing, the automatic blade control monitors blade load and changes blade elevation to avoid track slip and increase performance. Compared with add-on machine control dozers rough dozing efficiency was increased by 13 percent.
Komatsu typical add-on machine control system components have been replaced with factory installed cab top: Global Navigation Satellite System (GNSS), inertial measurement unit (IMU+) and sensing hydraulic cylinders. These systems are installed at the Komatsu manufacturing facility.
