Komatsu Europe International n.v. Launches D37EXi/PXi-23 Dozer Vilvoorde, June 2014 - Komatsu Europe International n.v. announces the introduction the D37EXi/PXi-23 dozer to the European market. Equipped with Komatsu’s latest intelligent Machine Control technology, the D37EXi/PXi-23 can perform both finish grading and rough dozing in full automatic blade control mode. This is the second intelligent Machine Control Komatsu dozer model available in Europe. Inside the cab, customer selectable dozing modes allow system response to be tailored to the current machine operation for optimized performance. Similarly, blade load settings are adjustable between pre-sets to match actual material conditions. Pass to pass, the intelligent Machine Control system can be left with the automatic blade control engaged because of its ability to precisely automate the lowering of the blade at the start of a pass and raise it at the end of a pass. Improvement in combination rough dozing efficiency is significantly higher compared to add-on machine control systems. Integrated: Standard Factory Installed Integrated Machine Control System Typical add-on machine control system components mounted on the blade are replaced on the D37EXi/PXi-23 with factory-installed cab top GNSS (Global Navigation Satellite System) antenna, enhanced inertial measuring unit (IMU+), and stroke sensing hydraulic cylinders. These components along with the machine control monitor and controllers mounted inside of the cab are installed at the Komatsu manufacturing facility during machine assembly. They ensure a quality installation and reliability. When the machine travels around the job site, the cab top GNSS antenna collects accurate surface data by measuring actual elevations. The stroke sensing angle cylinder measures the angle of the blade for high precision grading accuracy on cross-slope, blade angled or not. EU Stage IIIB with smart engine technology The dozers meet EU Stage IIIB regulations using smart engine technology, with operator-specific features bundled into a compact 89 horsepower package. Long track-on-ground standard (EXi) and low ground pressure (PXi) models are available to offer flotation and weight distribution options to customers and best match their applications. Operating weights range from 8,640 kg to 8,940 kg. depending on the configuration and model. At 2200 rpm, the D37EXi/PXi-23 pushes with a net 66,1 kW (89 HP). No need for a Diesel Particulate Filter The dozers come equipped with the Komatsu Diesel Oxidation Catalyst (KDOC), which has an integrated design that does not interfere with daily operation. This smart and simplified system removes soot using 100% “passive regeneration” without the need for a Diesel Particulate Filter (DPF). The KDOC has no scheduled replacement interval and is designed for long life with no required maintenance. For owners, this means lower owning and operating costs due to less complexity and seamless operation for the operator. A Variable Flow Turbocharger, direct flow air filter, high pressure common rail fuel injection, 16valve cylinder head and Exhaust Gas Recirculation (EGR) are used on the D37EXi/PXi-23, resulting in precise air flow management and more complete combustion, eliminating the need for a DPF.

Unrivalled blade visibility and ride The steeply sloped engine hood and forward cab design provide more room for operators while moving them closer to the blade, for improved blade visibility, ride quality, enhanced grading ability and overall comfort. The cab also has an integrated ROPS / FOPS structure and is designed with large glass windows for better visibility. Internal cab air pressure and air filters minimize dust entering the cab, and viscous cab damper mounts suppress noise and vibration when traveling over rough terrain making these new models quieter than their predecessors.
