Wheel Excavator JH9120
Energy Saving and Powerful Performance
The JH9120 features advanced precision matching design and energy-saving control systems that ensure minimal fuel consumption, greatly reducing operating costs. Equipped with a new cooling fan and large silencers, it effectively lowers noise pollution to provide a more comfortable working environment.
Powered by the YCF36100 engine with a rated power of 74 kW at 2200 rpm, combined with advanced turbocharging technology, this excavator maintains stable and efficient operation even in high-altitude and harsh environments. Its unique funnel-shaped fan cover significantly increases air intake and cooling efficiency, ensuring sustained power and reliable heat dissipation during long working hours.
Durable and Adapted to Harsh Working Conditions
The JH9120 used excavator is equipped with high-end hydraulic components from internationally renowned brands, including the main pump, main valve, rotary motor, travel motor, hydraulic cylinders, and pilot valves, ensuring system stability and reliability. The latest energy-saving designs improve response speed and optimize operational efficiency.
Precise Slewing Control: Strong torque reserve and excellent vibration absorption enable accurate and smooth slewing stop actions, enhancing both operator comfort and machine performance.
Cushioned Hydraulic Cylinders: The boom and arm cylinders feature cushioning functions that reduce machine vibration and shock, lower noise levels, and prolong cylinder service life.
Dual Pump Confluence Technology: Increases oil flow to the main valve cylinders supplying the boom, arm, and bucket, improving operation speed for enhanced productivity.
Durable and Adapted to Harsh Working Conditions
The JH9120 has a reinforced chassis equipped with hydraulic power steering and wheel-side reduction axles, significantly enhancing mechanical flexibility and durability. Critical hinge parts on the bucket arm use forged structures, with optimized plate shapes and thickness to reduce stress and improve strength.
The boom and arm are integrally welded and precision bored and polished, ensuring a solid structure that prevents weld fractures and extends the lifespan of pins and bushings. The bucket uses special wear-resistant steel plates, equipped with wear-resistant bucket teeth and side teeth to meet heavy-duty operation requirements.
Additionally, thicker steel plates and side stiffeners improve wear resistance, and the flat-bottom bucket design helps form smooth surfaces for efficient loading.
Comfortable and Safe Operating Environment
The JH9120 used excavator features a spacious cab with an expanded field of view through large front, side, and rear windows, greatly reducing blind spots and enhancing operational safety. An enlarged skylight improves upward visibility and ventilation. Tempered glass shading panels protect the cab from direct sunlight, ensuring interior comfort.
Ergonomic design is applied throughout, with easy-to-control operation handles and centrally located function switches for convenient operation. The deluxe interior includes a large LCD display that monitors engine speed, water temperature, oil pressure, and other key parameters for real-time machine status awareness.
The cab is equipped with air conditioning and heating systems for rapid temperature adjustment, providing comfort year-round.
Intelligent Monitoring and Convenient Maintenance
The machine is equipped with a multifunctional large LCD screen for digital real-time monitoring of working conditions, supported by GPS global positioning system for remote diagnostics, fault warnings, and automatic alerts. This facilitates efficient maintenance management and reduces downtime.
All filters—including oil, pilot oil, fuel filters, and oil-water separators—are installed at ground level for easy inspection and replacement. The large-capacity fuel tank supports extended working hours, and spacious toolboxes provide ample storage for spare parts.
