Working scene of tunnel arm
Special design----meet customer needs !!!
What are the advantages of modifying the tunnel arm?
1. The operating range adapts to the working conditions, and there is no need to worry about the boom hitting the beams of the tunnel or basement.
2. After the tunnel boom is modified, a larger breaker can be used due to the shortening of the boom. For example, the PC120 excavator can carry a 135 breaker after modification, and the PC200 excavator can use a 165 breaker, but it is necessary to increase the confluence of double pumps, and the impact force is doubled.
3. The tunnel boom can carry a bucket. The shorter the boom, the shorter the torque, the greater the force, and the larger the bucket can be.
4. When the bucket replaces the breaker, the stop valve prevents oil leakage.
5. The pipe joints are multi-layer welded to reduce the risk of oil leakage.
6. The cylinder guard is conducive to preventing the cylinder from being damaged in a collision.
7. Factory price, cheap price, support customization, ODM or OEM service.

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).
