high efficiency, high reliability and high durability of the Komatsu 390. Specifically, its high efficiency features benefit from a high-power engine and an efficient hydraulic system, the combination of which improves the operating efficiency of the equipment. In addition, the 1.9m ³~2.1m³ high efficiency rock bucket is configured to further improve the loading efficiency and operation volume. In terms of reliability and durability, the main components of Komatsu 390’s engine and pump are imported from Japan, which improves the reliability of the equipment. The improvement of manufacturing precision of rotary system and the use of large fuel pre-filter and fuel tank breather valve and other structures reduce the damage degree of impurities to the fuel system. At the same time, the hydraulic system adopts the combination of hydraulic tank breather valve and large hydraulic oil filter to improve the reliability and durability of the hydraulic system. In addition, self-discharging dust air pre-filter and large air filter are used to reduce the pollution of environmental dust on the intake air. Together, these designs and configurations ensure the high stability of the Komatsu 390, which is enhanced by the use of a 40-ton highly reliable chassis
