Special design----meet customer needs !!!
Advantages of Modifying the Tunnel Arm:
1. By modifying the tunnel arm, its operational range is optimized for different working conditions, ensuring no interference with tunnel beams or basement structures.
2. Post-modification, larger breakers can be utilized; for instance, a PC120 excavator can handle a 135 breaker while a PC200 can support a 165 breaker, which requires increasing the confluence of double pumps to double the impact force.
3. The ability to carry a bucket increases with a shorter boom, allowing for more force and the use of larger buckets.
4. A stop valve is in place to prevent hydraulic fluid from leaking when transitioning from a breaker to a bucket.
5. Multi-layer welding on pipe joints enhances durability and reduces oil leak risks.
6. The cylinder guard is beneficial for preventing damage from collisions.
7. We offer competitive factory pricing along with customization options for ODM and OEM services.

|| Excavator Tunnel Arms Suitable For Application
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
What is the purpose of beveling the long arm/tunnel arm plate?
Most welding machines commonly used in the industry have a penetration depth of only 3mm. Since the thickness of our long arm plate is at least 8mm, without beveling, the welder would not be able to fully penetrate through the entire joint. This would result in weak welds, leading to issues such as weld cracking in the future.
We employ mechanical beveling, whereas other factories rely on manual beveling (as shown in the figure).
