With superior performance and outstanding quality, it has won the "TOP50 Ma

With superior performance and outstanding quality, it has won the "TOP50 Market Performance Award" of China's construction machinery. The all-new generation SY365H-S National IV machine inherits the classic and is highly efficient and energy-saving

Comprehensive upgrade, reduced fuel consumption, equipped with multiple intelligent technologies, and significantly enhanced overall performance

High efficiency and low fuel consumption

Compared with the National III engine, the SY365H-S National IV engine has an efficiency increase of 3-5% in the main gears while maintaining the same fuel consumption. The bucket capacity has been increased from 1.6 cubic meters to 1.9 cubic meters, the operation efficiency has improved by 10%, and the overall energy efficiency has been enhanced. Adopting the "positive flow" system and Sany's independently developed "DMOS" engine-pump-valve integrated dynamic optimization intelligent control system, its efficiency far exceeds that of competitors, with an efficiency of 40 tons and a fuel consumption of 30 tons.

The original fully imported engine with enhanced power has a power and torque reserve of over 10%, providing strong performance and helping customers solve problems under heavy-load working conditions. National IV emission standards adopt the DPD route, eliminating the need to add urea for emissions, which is worry-free and convenient. The powertrain has been upgraded, with the main pump displacement increasing from 160cc to 180cc, making the overall operation faster.

The large-capacity three-stage filtration system can handle various fuel quality products. It is equipped with a filtration system that exceeds the standard, with a flow capacity of over 600L, meeting the requirements of a 60-ton excavator.

The working device has been comprehensively upgraded

The boom boom is widened, the section coefficient is increased by more than 10%, and the service life is improved. Optimization of welding processes, such as single-sided welding and double-sided forming, TIG welding toe trimming and fusion, etc., to eliminate stress concentration. Strengthen the local high-stress areas, reducing the average stress by more than 10% and extending the service life by over 12,000 hours.

The original five chisel-shaped teeth have been upgraded to four pointed bucket teeth, and the 50mm front edge plate has been increased to 60mm. Through the optimization of the hinge point, the range of application of the digging force is wider, and the digging force of the bucket arm is increased by 15% to 210KN. The optimization of the mechanism's running trajectory and bucket shape reduces the impact and resistance on the machine during excavation, increases the excavation speed, enhances the operation efficiency, and doubles the service life of the bucket.

Reinforcement of the walking device

The vehicle is reinforced for higher stability. The 40-ton class slewing bearing is adopted, and the cross-section of the X-frame is increased to 330mm, an increase of more than 5%, improving the reliability.
