What Are the Benefits of Tunnel Arm Modification?
1. Modifying the tunnel arm enhances its operational range, allowing it to adapt to various working conditions without the risk of colliding with beams in tunnels or basements.
2. After modifications, the ability to use larger breakers is possible; for instance, the PC120 can support a 135 breaker and the PC200 a 165 breaker, requiring an increase in double pump confluence to effectively double the impact force.
3. The shorter boom enables the tunnel arm to lift larger buckets more effectively, as reduced torque translates into greater force.
4. Incorporating a stop valve prevents oil leakage when using a bucket instead of a breaker.
5. Multi-layer welding on the pipe joints significantly reduces the likelihood of oil leaks.
6. The cylinder guard offers protection against damage from collisions.
7. Our services are provided at factory prices, including options for customization through ODM and OEM.

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).
