Mining Construction Work Excavator Rock Ripper Boom Arm for Excavator SY550
2024 Zhonghe Machinery Catalogue 3M.pdf

① Bucket cylinder is inverted:

It effectively avoids damage to the piston rod caused by possible collisions during excavation, reduces use risks and saves

② Increase the volume and weight of the arm:

The digging force is stronger, the operation is easier and the efficiency is higher.

③ The thickness of the arm and ripper decreases:

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.

④ The boom integrated head:

The structure is stronger and stronger, effectively reducing the risk of cracking caused by high-intensity operations.

⑤ Cylinder through-pin design:

The process requirements are higher, the concentricity is higher, the wear is reduced, the life is longer and more durable.

⑥ Adjust the hinge point position of the lifting cylinder:

Make the lifting

⑦ The small arm and ripper are designed without connecting rods, which has strong digging force and can excavate side slopes.

⑧ The bucket cylinder has a 150mm piston rod, and the stick cylinder has a piston rod of 140mm, with stronger power.

If necessary, a protective device can be designed into the bucket cylinder to make the bucket cylinder more durable and can be customized.

⑨ The iron sand packed in the boom and small arm boxes has a more balanced weight and uniform density. It will not cause one side of the cylinder to be stressed due to excessive weight on one side, causing damage to the cylinder, which is beneficial to reducing failures.

⑩The bucket teeth are wearing parts , so we use the best materials. The ripper teeth and tooth seats we use Diamond D11 are more wear-resistant and not easy to break.Moreover, the maintenance cost for customers will be relatively low in the later period.

Bubble bag packaging for most products.

Wooden case for little products, like buckets.
Iron frame support for boom arms.

The accessaries and package of excavator long boom arm are subjected to our final confirmation.
