Features1. Undercarriage steering hydraulic systemWe imported, digested and applied the updated steering valve of Komatsu, which lead to compact structure and easy operation.2. Electronic monitor systemThe 3-stage alarming & monitoring system is mounted in cabin, which can measure and monitor voltage, oil pressure, water temperature, oil temperature, engine speed. It also can monitor the status of fuel oil, cooling water and the condition of air filter. By the twinkling of light and buzzing of horn, the system can inform drivers the essential information of bulldozer and assure bulldozers working in normal, safe and high efficiency condition. There are also engine oil pressure gauge and water temperature gauge in the instrument panel to make parameters visible and own two-tier protection function.3. Transmission, hydraulic parts, undercarriage and working equipmentInter-changeable with same products of Komatsu as well as those products that are produced according to Komatsu technology.4. The operating system is designed to be reasonable, handy and comfortable and allow more working place for the driver.5. Final driveThe final drive gear is produced according to the imported technology strictly. Our imported specialized gear-processing equipment insure the high quality and the leading position in China.6. The cabin is hexahedron with wide view scope.Shanghai-PD220Y-1 bulldozer is the only one which import updated technology of Komatus D85A-21and occupy leading position in China.ModelItemPD220Y-1PD220YS (swamp type)Weight (kg) (including straight tilt blade and cab)Operation weight2550026300Shipping weight2500025500Ground pressure (MPa)0.0820.039EngineModelNT855-C280S10TypeVertical, four-stroke, water cooling, straight injection, turbochargedRated speed (r/min)18001800Rated power (HP/KW)220/164220/164Min fuel consumption ratio (g/kw.h)218218Transmission systemTorque converter3-element, single-stage, single phaseGear boxPlanetary gear, multiple-disc clutch, hydraulic actuated, forced lubrication by gear pump, (Electrical-hydraulic control for model PD220Y-3.)Bevel gearSpiral bevel gear, single-stage reduction, splash lubricatedSteering clutchWet, multiple-disc clutch, spring loaded and hydraulically released.
