In heavy-duty operation scenes such as large-scale mining and large-scale infrastructure projects, the dynamic performance, transmission efficiency and driving comfort of bulldozers directly determine the construction progress and comprehensive value of equipment. Focusing on the requirements of high load and long-term operation, Shanbo SD32 bulldozer takes the electronic control engine with strong compliance as the core, matches the efficient and adaptive transmission system, and is supplemented by the intelligent cockpit design to create all-round construction equipment with "sufficient power, smooth transmission and comfortable driving", which has become a reliable choice to meet the challenges of large-scale projects.

From the core power point of view, Shanbo SD32 bulldozer is equipped with WP12/QSNT-C345 electronic control engine, which not only meets the national non-road machinery country III emission standard, but also achieves triple breakthroughs in power output, operation efficiency and operation and maintenance cost. As two mature and reliable high-power electronic control engines, WP12 and QSNT-C345 both adopt advanced electronic control technology, which can adjust the fuel injection amount and combustion rhythm in real time according to the workload —— when the engine is working on a heavy load and climbing a hill, it can suddenly burst into strong power, easily meet the demand for pushing tens of cubic meters of earth and stone, and avoid the interruption of work caused by insufficient power; In light load transfer, site cleaning and other scenes, it can automatically optimize fuel consumption and realize intelligent adjustment of "heavy load and strong power, light load and fuel saving". At the same time, the addition of the electronic control system makes the engine fault diagnosis more accurate. Through the on-board system, the key parameters such as speed, oil temperature and oil pressure can be monitored in real time, and once there is abnormality, the alarm can be given in time and the fault position can be prompted, thus reducing the investigation time of later maintenance; Moreover, the wearing parts of the two engines have strong universality and sufficient market supply, and it is convenient to replace parts such as oil filter and air filter during daily maintenance, which greatly reduces the long-term operation and maintenance cost and keeps the equipment always at a high attendance rate.

The transmission system is a "bridge" for power transmission. The transmission system of the SD32 bulldozer is deeply adapted to the engine curve, and the engine performance advantage is completely released. Through repeated testing and debugging, the R&D team makes the rhythm of power receiving and transmission of the transmission system highly fit the power output curve of the engine. When the engine is in the high-efficiency power zone with medium and high speed, the transmission system can accurately receive power and control the power loss in a lower range, which not only has a wider efficient operation range, but also can significantly improve the transmission efficiency. In practical operation, the advantages brought by this adaptability are particularly obvious: in mine stripping operation, bulldozers need to switch frequently between "heavy-load bulldozing-empty-car returning" modes, and the transmission system can quickly adjust the transmission ratio according to the change of engine speed, so as to avoid power connection jamming and make the fuselage start smoothly and accelerate smoothly, which not only reduces the impact wear of mechanical parts, but also improves the number of operation cycles per unit time; Even in the construction site with large slope, the transmission system can stably transmit power, and cooperate with the torque output of the engine to ensure that the bulldozer does not slip down the slope and turn off the engine when climbing, and to ensure the safety and continuity of heavy-duty operation.

On the aspect of driving experience, the cockpit of Shanbo SD32 bulldozer takes "intelligence and humanization" as the core, creating comfortable and convenient working space for operators. The intelligent display and control terminal equipped in the cockpit is the "intelligent brain" of the equipment operation state-the terminal screen clearly presents real-time data such as engine speed, transmission oil temperature, working device position, etc., and the operator can fully grasp the equipment operation through the screen without bending over to check the mechanical parts; At the same time, the terminal supports fault code query, maintenance cycle reminder and other functions. When the equipment needs to change the oil and adjust the tension of the track, the system will automatically pop up a window prompt to avoid the loss of parts caused by missing maintenance. In addition, the cockpit is also equipped with a cooling and heating integrated air conditioner, which can quickly adjust the cabin temperature according to the outside temperature-when working at high temperature in summer, the cold air can evenly cover the entire cockpit, effectively dispelling the sultry heat; In the severe cold environment in winter, warm air can quickly raise the cabin temperature, and avoid the operator's stiff hands from affecting the operation due to cold. The air conditioning system also has the function of dust prevention and filtration. When working in dusty mines and infrastructure sites, it can prevent external dust from entering the cockpit, keep the air in the cabin clean, and cooperate with the cockpit door and sound insulation cotton with excellent sealing performance to further reduce external noise interference, so that operators can concentrate on their work in a relatively quiet and comfortable environment and reduce fatigue caused by long-term operation.

On the whole, Shanbo SD32 bulldozer, with its compliance and strong electronic control engine, efficient adaptive transmission system and intelligent and comfortable cockpit design, can not only meet the requirements of large-scale projects for high power and efficiency, but also provide humanized driving experience for operators, effectively balancing "working performance" and "personnel care" and become the core equipment to promote the efficient and safe promotion of large-scale projects.
