In the construction machinery sector, hydraulic systems are hailed as the “power heart” of excavators, directly determining equipment efficiency, control precision, and energy consumption levels. Particularly in the mini excavator segment, where operators face confined urban workspaces, complex conditions, and stringent energy-saving and environmental requirements, hydraulic system upgrades are pivotal to core competitiveness. As a dedicated pioneer, leverages breakthroughs in hydraulic technology to develop high-speed, low-energy, and highly reliable hydraulic systems, revolutionizing small-scale engineering operations.

Mini excavators are widely used in urban landscaping, municipal maintenance, and agricultural planting. Their confined working spaces and variable conditions impose stringent demands on hydraulic systems: precise control for fine-grained operations, rapid energy conversion to reduce consumption, and robust stability to handle load switching.

Traditional mini excavator hydraulic systems suffer from significant shortcomings: first, substantial energy loss, with open-loop overflow causing increased fuel consumption and excessive oil temperatures; second, insufficient control precision, where complex multi-actuator movements often interfere, impacting efficiency; third, poor adaptability, failing to dynamically match varying load demands.

Addressing these industry pain points, collaborated with core suppliers to develop a new generation of intelligent hydraulic systems. Through triple upgrades in circuit architecture, core components, and control strategies, it achieves three core advantages:

First, a revolutionary rapid circuit architecture. Abandoning traditional open circuits, it adopts a load-sensing + closed-loop combination design that dynamically matches actuator load demands, precisely allocates flow, and drastically reduces overflow losses. The closed-loop system also enhances contamination resistance, adapting to dust interference in complex operating environments.

Second, high-precision core component integration. Equipped with a high-performance axial piston variable displacement pump and premium electromagnetic proportional valves, it delivers rapid response and real-time hydraulic oil flow adjustment to prevent overflow waste. Upgraded cylinder seal structures minimize internal leakage, enhancing system sealing integrity and reliability.

Third, intelligent energy-saving control strategy. Through electronic proportional control and adaptive operating condition algorithms, it dynamically adjusts pump displacement and valve opening, optimizes composite action priority allocation, and reduces operational interference. It achieves intelligent power matching between the engine and hydraulic system, reducing displacement and unnecessary work during idle periods while ensuring digging force under heavy loads. Energy consumption is reduced by 15% under equivalent operating conditions.

In actual operations, the micro excavator demonstrates significant advantages. During urban renovation projects in older neighborhoods, precise hydraulic control enables rapid completion of intricate tasks like trench excavation in confined spaces, boosting daily output by 10%. In agricultural greenhouse construction, the machine maintains stable oil temperatures during 8-hour continuous operation, offering longer lifespan and lower maintenance costs than conventional models. User feedback indicates that core hydraulic components come with a 1-year warranty, combined with online monitoring and early warning systems, significantly reducing unplanned downtime.

As the mini excavator market evolves toward intelligent and low-carbon solutions, hydraulic innovation is pivotal to competitiveness. commits to deepening the integration of hydraulic systems with smart technologies to explore faster, more energy-efficient solutions. Through technological breakthroughs,  not only addresses pain points of conventional equipment but also drives the advancement of compact construction machinery. Remaining user-centric, will continue delivering reliable solutions for urban development, agricultural growth, and other critical applications.
