Recently, our company announced a major breakthrough in the core technology of small construction machinery. The new generation of intelligent hydraulic system has been officially applied to the entire series of mini excavator products, which completely solves the industry pain points such as high energy consumption and insufficient control precision of traditional models, and promotes the upgrading of mini excavators towards intelligence and low carbon emissions.
As the "power heart" of an excavator, the hydraulic system directly determines the equipment's operating efficiency, control precision, and energy consumption. Addressing the needs of mini excavators in confined working environments such as urban greening, municipal maintenance, and agricultural planting, Shandong Tienu, in collaboration with core suppliers, has developed a new generation of intelligent hydraulic systems that combine high efficiency, energy saving, and reliability after two years of research and development.
The system achieves a performance leap through three upgrades: First, the loop architecture is innovated, adopting a load-sensitive + closed loop combination design to match the load requirements of the actuator in real time and significantly reduce overflow losses; second, the core components are upgraded, equipped with a high-performance axial piston variable pump and electromagnetic proportional valve, resulting in faster response speed and significantly improved control precision; third, the intelligent control is optimized, achieving intelligent matching of engine and hydraulic system power through working condition adaptive algorithms, reducing energy consumption by 15% under the same working conditions.
Through actual operation tests, the mini excavator equipped with the new generation intelligent hydraulic system has increased the daily workload by 10% in scenarios such as the renovation of old urban communities and the construction of agricultural greenhouses. The oil temperature remains stable after 8 hours of continuous operation, unplanned downtime is greatly reduced, and maintenance costs are reduced by 18%.Going forward, the company will continue to deepen the integration of hydraulic systems and intelligent technologies, explore more efficient and energy-saving technical solutions, build core competitiveness through technological innovation, and provide users with better operational solutions.
