1. The sliding arm is used to dig deep wells, foundation pits, tunnels, sewage pipelines and other municipalities. 2. Our company was established in 2018 and has more than 6 years of experience. The production line engineers have more than 10 years of data and experience to design and customize long arms for excavators of various brands. 3. Suitable for all excavator models, OEM services are also provided. 4. Advanced manufacturing process, technology meets global standards. 5. We have all the installation dimensions for most excavators, and we can customize this long arm for your excavator. 6. Before welding, we use a large milling machine to mill (taper processing) the edge of the steel plate. Therefore, the welding can enter the inside of the steel plate, giving the structure higher performance. And there are reinforcement plates inside to make it stronger. 7. If necessary, additional pipes can be added to accommodate some additional applications. 8. The arm cylinder of the long boom, you can use your original arm cylinder to save costs, if you need an arm cylinder, we can also prepare it for you. 9. Some parts can be reinforced with thicker plates or overlap another plate for heavy-duty applications. 10. Welding is shielded gas welding, the shielding gas is a mixture of 80% argon and 20% carbon dioxide. This is the gold standard of shielding gas. 11. Before welding, we use a large milling machine to mill the edge of the plate. So the welding can go inside the steel plate, making the structure have higher performance. 12. We can customize the arm for various excavators according to your requirements. Just tell me your requirements. 13. If you need, some parts can be reinforced with thicker plates or overlap another plate for heavy-duty applications, just tell me.
What is the role of beveling the long arm plate?
The melting depth of the welding machine commonly used in the industry is only 3mm thick. The plate thickness of our long arm is at least 8mm. If the beveling is not opened, the welding machine will not be able to penetrate the entire weld, so the welding effect will be poor, and the weld cracking and other problems will occur later.
We use machinery to make the bevel, while other factories use manual bevel (as shown in the picture)

Production Using High-precision Instruments
Plasma cutting machine
Plates less than 30mm thick are plasma cut, while those over 30mm are flame cut. Plasma cutting deformation is 0.1 mm.CNC plasma cutting with less panel deformation.
Double sided boring machine
Improved accuracy and consistency: Since the boring pin operations on both sides of the double-sided boring machine are performed simultaneously, the machining accuracy and consistency on both sides can be guaranteed.
Beveling machine.
Mechanical beveling is used instead of flame beveling. We only reserve 2mm of plate thickness for beveling, so that the plate and welding material can be welded better. By opening the bevel, the welding machine can penetrate the entire weld bead, making it less likely to cause problems such as cracking of the weld bead.
Our factory has a complete range of production equipment, which is conducive to the production of our products, good quality and ensures product accuracy.
1. Panel is cut by CNC plasma machine with less deformation. 2. Tolerance within 5-10um, ensure the accuracy of hole . 3. Environmentally friendly verified spraying room. 4. GMAW-Gas Metal Arc Welding. 5. Plasma cutting machines, boring machines, beveling machines, bending machines, etc. ensure accuracy.
