Zhonghe triple quality control system
The first system is the technical design drawing review mechanism,
The second system is the semi-finished product review mechanism,
(Each process has the inspection of the previous process)
The third system is the finished product inspection.
(Before painting, conduct an overall inspection to check whether the design size matches the welding size and whether the installation size meets the design requirements.)
In summary, every product of Zhonghe has passed the above three-level inspection system to ensure that it can be shipped only after it is qualified.

Some questions and answers that may interest you
Q: Are you a manufacturer?
A: We are a manufacturer/supplier of excavator arms and accessories. We have a super large factory with an area several times that of our competitors. We are the largest excavator accessory factory in Guangdong Province with complete production equipment and our products are exported to more than 60 countries around the world.
Q: Why is there a difference between a bucket and a grab bucket for telescopic arms?
A: Generally, for silt and gravel, the bucket is easy to use, has a large digging volume, and is more efficient. However, in general sand and gravel operations, the bucket has no digging force and is restricted by the opening, so the efficiency of the bucket will be reduced. The grab bucket is more suitable for this operation. However, due to the large overall weight of the grab bucket, the volume of the grab bucket is generally smaller than the bucket bucket, but in operations with more stones, the advantages of the grab bucket are more obvious.
Q: Is it better to use a single cylinder or a double cylinder for a bucket with a telescopic arm?
A: We have always used a double cylinder design and never a single cylinder design. Its advantages are low failure rate, easy maintenance, and less oil leakage. What are the disadvantages of a double cylinder? First of all, the bucket of the double cylinder is heavier and the synchronization of grabbing is poor. The overall weight of a single cylinder is low, the synchronization is good, the grabbing efficiency is high, but the failure rate is high.
Q: What is the material of the telescopic arm?
A: The arm tube uses BS900E, and other parts use Q3558, which is light and durable. We use 6mm thickness.
