First, the power auxiliary system with efficient protection and environmental protection.

Shanbo Hydraulic Tracked Bulldozer has made dual efforts in engine protection and environmental protection emission. The Secco double pre-filtering air intake system can efficiently intercept dust, sand and other impurities in the air through two-stage filtering design. The first-stage pre-filtering first filters large-particle impurities, and the second-stage fine filters tiny dust, so as to prevent particles from entering the engine cylinder with the air intake, prevent the premature wear of precision parts such as pistons and valves, reduce the early failure of the engine caused by the invasion of impurities from the source, and prolong the service life of the engine, especially suitable for harsh working environments with many dusts such as mines and infrastructure.

At the same time, the engine is equipped with a common rail fuel system (MCRS), which can accurately control the fuel injection pressure and injection timing, make the fuel atomization more uniform and burn more fully, greatly reduce the emission of pollutants such as nitrogen oxides and particulate matter while improving the power output efficiency, and easily meet the requirements of Euro A/III emission, which not only conforms to the current environmental protection policy, but also reduces the pollution to the working environment and helps the construction of green projects.

Second, the intelligent and energy-saving transmission system

The transmission system of bulldozer adopts the dual-mode design of "low-speed hydraulic transmission+high-speed mechanical transmission", giving consideration to the stability of operation and fuel economy. When working at low speed (such as earth leveling and fine shovel loading), switch to hydraulic transmission mode. The buffering effect of hydraulic oil can make the power transmission smoother, avoid the frustration caused by load fluctuation and improve the operation accuracy; When the equipment enters the high-speed driving state (such as long-distance transition), the system automatically switches to mechanical transmission, which reduces the power loss in the process of hydraulic transmission and saves 10%-15% fuel compared with the traditional single transmission mode. Long-term operation can significantly reduce the fuel cost for users.

In addition, the transmission system is equipped with a hydraulic torque converter with locking function, and its output torque can be dynamically adjusted according to the working load-when facing soft soil, the torque is automatically reduced to avoid power waste; When encountering hard soil, gravel and other working conditions with large resistance, the torque can be increased in real time to ensure the working power, without frequent manual adjustment, which greatly enhances the adaptability of the equipment to different loads, and enables the bulldozer to maintain an efficient working state under various complex working conditions.

Third, a safe and reliable braking system

In order to ensure the safety of operation, bulldozers are equipped with targeted braking protection design. In the ramp operation scene, the system can effectively prevent the vehicle from skidding through optimized power distribution and track grip control —— when the track skidding trend is detected, the power output of the tracks on both sides is automatically adjusted to match the high grip lines of the tracks, so as to enhance the stability of the equipment on the ramp and avoid safety accidents caused by skidding, which is especially suitable for multi-ramp operation environments such as mountains and highlands.

At the same time, the equipment adopts a normally closed brake, which is in a braking state under normal conditions, and maintains a stable braking effect only when parking is needed, so as to ensure that the equipment will not slip when parked (even on the ramp). Its structural design is simple and reliable, and the braking response is rapid, which can provide solid safety guarantee for operators and job sites, and further improve the operation safety of equipment.
