ENERGY-SAVING

 —  Customized Engine
Equipped with original YANMAR engine which is imported from Japan, the fuel injection system is perfectly matched with electric control system, it provides optimal fuel utilization to machine. The advanced fuel filter, oil filter and air filter can provide great protection to engine.

 — Efficient Hydraulic System
Hydraulic system adopts load-sensing hydraulic control system which is optimized by  Japan Engineering Center, it has excellent controllability and can adapts various applications.

 — Advanced Technology and Optimal Machine Performance
Adopts electronic- control main pump which can intelligently adjust the power matching between the main pump and the engine according to the loading changes, the fuel is dramatically saved while assuring high efficiency

RELIABILITY
 — Superb Match
The key parts of the power system, hydraulic system and electronic control system are specially customized to achieve perfect matching and compatibility with one another, which deliver maximum reliability and longer service life.
 —  Core Components
Relying on the R&D system of  Japan Engineering Center,  has established a solid partnership with world-renowned companies to continuously optimize and improve the quality and service life of our key components. Industry leading components are used on our machines including engine, pump, valve, motor, oil cylinder, controller and forth.

 — Reinforced Working Device
The front & rear support of boom and front support of arm are made of cast steel, which effectively reduces concentration of stress and increases the service life dramatically. The arm is also reinforced to improve the durability.

COMFORT

 — Large Spacious Cab
Equipped with spacious cab which provides operator large space to operate machine. The premium suspension seat with armrests is very comfortable and it can reduce the working fatigue dramatically. Big LCD screen is easy to read all data and to operate when working. Air conditioning is added for maximum comfort.

 — Ergonomic Design
The proportional joystick delivers sensitivity, accuracy and smoothness during operation. This joystick is specially designed to meet different operating conditions. Intelligent control system is standard which could control diverse attachments such as bucket, hammer, scarifier and hydraulic scissors.
 —Low Noise and Low Vibration
In order to reduce work fatigue and improve productivity, the noise inside of cab has been controlled to the lowest level. The cab is attached to the frame with buffer that dampens vibrations and sound levels to enhance operator comfort.

SERVICEABILITY
 — Engine hood and panels
The large engine hood increases maintenance space for operator to check and maintain the engine. The tool box is big with big opening angle which can put grease bucket and special tools easily. One key can open all locks of machine, it is very convenient for operator. 
— Electric and Hydraulic Parts
Pressure sensor is used on the main pump which can monitor hydraulic system’s pressure when working. Centralized lubrication makes convenient and easy maintenance to slewing bearing, and the radiator is optimized for easy cleaning. These configurations make routine maintenance easy and convenient. 
 — Filters and Maintenance Period
All the filters are fixed at ground level position, it is very convenient to do routine maintenance. The maintenance interval is also extended to save time and cost.
