Machine test: CL-6 machine test ground occupies an area of more than 300 mu, consists of various of operating conditions such as earthwork, stonework, sand-gravel material; Different testing sites such as for bump vibration strengthening test, noise test, operating efficiency, fuel consumption, walking test and slope-climbing test; Every new product is subjected to a combination test of more than 2000 hours (including digging, crushing, bumping, climbing, and various performance tests).

· System test: CL-5 comprehensive performance test room and CL-4 pump valve, electrical, structural parts strengthening and vibration test bench are established to, carry out component performance and reliability test before development.

· Test standards: Based on the study on example and Japanese expert guidance, the evaluation standards and test database for performance test and reliability test of machines and system are completed, which supports product development verification and improves product performance and reliability.

The thermal treatment standard of the surface which is connected to the track is improved, which makes the parts more wear-resistant and the life is doubled;

· The track roller and idler adopt extremely cold type lubricating oil and seals to ensure normal operation under -40°C;

· Chain link track with lifelong self-lubricating and sealing abilities;

· Reinforced left and right track beams;

· Strong drive sprocket

Relying on the R&D Engineering Center in Japan, we have established a solid partnership with world renowned companies to continuously optimize and improve the quality and service life of our components. Meanwhile, engines, pumps, valves, motors, oil cylinders and controllers are provided in priority.

With continuously optimized design, stress testing, welding process and material research, the service lives of key structural parts are comprehensively improved; The Boom adopts box structure and high-strength steel plate, while with robot welding which extend service life by 100% in mining conditions.

he average service life of structural parts is increased by 50% and the strength is increased by 12%;

· The connection of boom adopts integrated casting;

·The shaft sleeve is copper-based graphite with self-lubricated;

· High-strength rock bucket teeth.

New type large-capacity rock bucket with high strength wear-resistant steel, the strength and wear resistance are increase by 40%.

Higher productivity and lower cost

Large power engine and excellent hydraulic system make the loading ability more outstanding, and the productivity increases by 15%.

While ensuring static digging force, we are committed to the R&D of dynamic digging force. When large resistance is encountered during the digging process, the system will automatically detect the pressure and adjust the output pressure to ensure the strong digging effect in the dynamic digging process.

In heavy duty working applications, the main controller automatically adjusts the power and speed according to the change of the load to ensure high output power, so as to improve the efficiency of machine

 Hydraulic system with latest technology make the working efficiency improved by 3% compared with the previous generation.

·Series of devices are suitable for various operating conditions;

· Designed to maximize productivity and durability, service life of structural parts increased by 50%;

· With large-capacity and wear-resistant bucket, make the operation in high-efficiency 

· A full range of maintenance oil and components are provided for FR370E-HD, which makes the maintenance cost lower;

· 5000 hours-long life hydraulic fluid.

Normal operating time of machine is extended and operating cost is reduced

·Allow to Monitor production and manage the efficiency of the working site.

Spacious and ergonomical designed cab with excellent vision makes the operator more comfortable to drive.

The cab is equipped with high-quality mechanical suspension seats, allows the driver to have a larger and more comfortable working environment.

 The cab meets the TOPS\FOPS standard, and equipts with a protective net device to make the quarry operation safer.

The special designed joystick provides precise control of the sensitivity, accuracy and smoothness during the operation. This control device is designed for machines that work under a variety of operating conditions.

In order to eliminate work fatigue and improve productivity, the noise rate in the cab is controlled at the lowest level.

The cab is mounted on an elastic base to fully absorb the vibration

The use of rubber flanges to support the pipe has a positive effect on noise reduction.

Intelligent control system allows one machines to adopt bucket, hammer, scarifier, rock arm and hydraulic shear

· The pin mounting point is located on the left side of the boom and ensure it can be found once it is loose;

· The platform adopts full protective anticollision beam to provide more protection for the revolving platform and cab.

· Rearview camera is optional f to improve safety of operation;
