The MC series is a master of the excavator product technology collection for more than 20 years. It is energy efficient and conforms to the national III emission. Comfort, efficiency and energy saving are the key words of MC216-9. It is durable, energy-efficient, and environmentally friendly. In order to ensure the smooth development of customer projects and obtain more benefits!
The MC216-9 design concept is reliable, efficient and energy efficient. Reliable is the cornerstone of the product. All performance should be based on reliability. The product design should fully consider the failure of the previous product and ensure the high reliability of the MC216-9. The high efficiency refers to the product adopting the positive flow system and the previous generation. Compared with the common working speed of the same working condition, the comprehensive working efficiency is increased by 10%; energy saving and environmental protection is the performance characteristic of the product, the lower fuel consumption can bring higher profits to the user, consume lower social energy, and the national three emissions can be effective. Reducing the environmental pollution caused by exhaust emissions is in line with the environmental protection requirements of today's society.

Operating weight: 20.8t
Bucket capacity: 0.9m3
Engine power: 124kW/2050rpm
Working pressure: 34.5 mpa
Stick length: 2925mm
Bucket maximum digging force: 146kn
01, power system
The power system adopts imported Cummins QSB7 six-cylinder in-line, water-cooled, EFI, turbocharged, air-air cooled engine, powerful power, reliable performance, energy saving and environmental protection, convenient maintenance, in line with national III emission standards; engine electronically controlled fuel injection The system controls the fuel injection according to various working conditions, and the fuel is completely burned in the engine, which makes the engine have the advantages of high power, fuel saving, low noise, etc., and greatly reduces exhaust pollution; all-aluminum side-by-side rectangular wave fins The heat sink has high heat dissipation efficiency, convenient cleaning and good heat balance effect.
02, hydraulic system
The hydraulic system adopts positive flow control hydraulic system, which is highly efficient and energy-saving. It can realize precise control of individual and compound actions, and has fast response speed, improved operation comfort and smooth movement. The hydraulic parts are fully equipped with internationally renowned manufacturers. Stable, good matching, soft operation, low internal pressure loss; boom and stick adopt 2 pump confluence, fast action speed and high work efficiency.
03, electrical system
The electrical system adopts intelligent electronic control system with independent intellectual property rights, 4.3-inch color monitor, integrated GPS function module, and based on the Shanjian Nebula platform, data acquisition and remote transmission, positioning, control, protection and firmware remote upgrade function can be realized. To ensure that the state of the machine is always in control, and the property is safe and secure.
04, cab and interior
The new cab and interior have a wider field of view and a more rational space layout; the all-round adjustment of the seat and ergonomic design makes the operation simpler and more comfortable, minimizing driver fatigue. High-power air-conditioning and air conditioning, equipped with direct-loading compressor, high reliability and good comfort.
05, structural parts
Structure optimization and finite element analysis are carried out to ensure high reliability of the traveling mechanism and working device; the upper frame adopts modal analysis technology, which is durable and effective in reducing machine vibration and reducing noise; the track frame adopts X-shaped structure. High strength and strong carrying capacity; the sprocket wheel and the roller are unified, the two points support, the bearing capacity is more reasonable, and the bearing capacity is stronger; through the CAE technology, the main bearing parts of the simulated boom arm are casted to reduce the defects themselves. Improve reliability; simulate the maximum stress condition of the boom stick, analyze the structure of the stress concentration area, and further optimize the structure to ensure its high reliability; strengthen the strength of the bucket side plate and the main blade and adopt the market proven The side edge of the tooth is used to increase the service life of the bucket.
06, appearance
The appearance of the new MC series "African Lion" brings strong visual impact; stamping and forming of counterweight, fuel tank, hood, side door, etc., and adopt electrophoresis treatment and new weather-resistant paint, environmental protection and corrosion resistance.
07, maintenance and maintenance
The fully open front and rear hoods and the added openable side doors fully consider the convenience of maintenance and maintenance of the parts. At the same time, the internal lubrication points are centrally lubricated, which greatly shortens the maintenance time, and is convenient and time-saving.
