2024 Factory Produce Heavy Duty Rock Arm For Sany SY500 With Excavator Ripper

2024 Factory Produce Heavy Duty Rock Arm For Sany SY500 With Excavator Ripper

✅ Bucket cylinder is inverted,It effectively avoids damage to the piston rod caused by possible collisions during excavation, reduces use risks and saves maintenance costs.

✅ Increase the volume and weight of the arm,The digging force is stronger, the operation is easier and the efficiency is higher.

✅ The thickness of the arm and ripper decrease,To reduce excavation resistance, the ripper can be inserted into the working surface as a whole, making the excavation deeper and enabling full bucket loading

✅ Adjust the hinge point position of the lifting cylinder,The structure is stronger and stronger, effectively reducing the risk of cracking caused by high-intensity operations.

✅Rivers cleaning dregging project

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 a detection testing for the previous process),

The third system is the finished product testing.
(Before painting, the overall inspection is carried out to check whether the design size matches the welding size, and whether the installation size meets the design requirement.)

To sum up, every single ZHONGHE product has been passed the above three-stage inspection system to ensure that is qualified before shipping.

Usually use 40GP container to load product !
