The advantages of the used Sany 305 excavator mainly include its powerful power system, high working efficiency, optimized hydraulic system, comfortable operating experience, excellent durability and low maintenance requirements. ‌

‌Powerful power system‌: The Sany 305 digger is equipped with an Isuzu 6HK1 engine with a rated power of 210kW, which meets the National IV emission standards, has a large displacement torque and strong power. The turbocharger adopts VGT (variable section turbocharger), which has a short response time, less speed drop, and reduces fuel consumption loss, especially in high-altitude areas. Excellent performance. In addition, the engine's usable speed range is increased, making it easier to operate in the economic fuel consumption zone ‌12.
‌High working efficiency‌: By adopting fully electronically controlled hydraulic technology, the oil return area of ​​the boom and dipper valve core is optimized, and the logic valve is adjusted to improve coordination and leveling performance. Add a boom buffer valve, optimize the oil return area of ​​the travel valve core, eliminate the impact of travel speed change, and thus improve work efficiency. Excellent durability and low maintenance requirements: The Sany 305 Heavy excavator has been optimized through structural parts design, stress testing, weld and plate research, durability testing, 100% UT flaw detection of key parts and two-axis fatigue testing and other advanced methods to comprehensively improve the life of key structures. By jointly conducting component life research with well-known research institutions, the life of core components is comprehensively improved. The oil dispersion system is enlarged, and the system operating temperature is 8-10℃ lower than that of ordinary used excavators, and the adaptability to high temperature environments is greatly improved. Cooperate with professional manufacturers to develop long-life engine oil, diesel filter, and hydraulic oil, the customer's maintenance cycle is extended by 1 times, and the product maintenance cost is reduced by 50% 3. These advantages make the secondhand Sany 305 excavator perform well under complex working conditions, can meet the various operating needs of different customers, and have good economy and efficiency, which has won the praise of many customers.Sany 30 tons mining excavator
