ZD165YS推土机履带式牵引装置(18.2T4.4米3)

ZD165YS bulldozers are manufactured according to advanced technology of Komatsu D65A. The main characters are following:1. Engine The engine is DONGFENG G6135ZG57 manufactured by Shanghai Diesel Engine Co., Ltd., and according to customers’ requires the engine can also be CUMMINS NTA855 manufactured by Cummins Co., Ltd. 2. Torque converter According to the imported technology of Komatsu D65A-8 bulldozer, the torque converter used to be 2-turbine, 4-element type. However, shortly after technology import by China factory, Komatsu changed its design from 4-element to 3-element in order to make torque converter fit whole machine more perfectly. Now, Tianjin 6443 factory also use the torque converter of SINOCAT-165 bulldozer. 3. Final drive According to the imported technology of Komatsu, the final drive gear is drum spur type. We imported specialized gear-processing equipment that insures high quality for our products. This kind of final drive has the advantage of strong anti-burden and high reliability. 4. Transmission, hydraulic parts, undercarriage and working equipment Those parts are inter-changeable with same products of Komatsu, and produced according to Komatsu technology. 5. Braking system It is single-leg braking system, which means when a single leg stamps on pedal the both braking band of right & left working in the same time. This kind technology also occupies leading position in China. 6. Electronic monitoring system The 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. 7. ZD165Y bulldozer is equipped with good-looking hexahedron cabin with wide visual scope. ROPS and FOPS can be mounted at the option of customers. 8. ZD165Y bulldozer has the outstanding advantage of low fuel-consumption, strong draw power, high reliable, easy to operate and safe, comfortable. The machine has been greatly approved by specialist in construction mechanical industry. DESCRIPTIONSPECIFICATONEngineTypeStraight vertical, four-stroke, water cooling, direct injection type.
