Special design----meet customer needs !!!
Why Consider Modifying the Tunnel Arm?
1.Adjustments to the tunnel arm’s operating range make it suitable for various job sites, reducing the risk of the boom hitting tunnel or basement beams.
2. After modifications, larger breakers can be employed; for instance, a PC120 can utilize a 135 breaker, while a PC200 can handle a 165 breaker, requiring enhanced double pump confluence to double the impact force.
3. A shorter tunnel boom allows for greater force, enabling it to support larger buckets effectively due to reduced torque.
4. The inclusion of a stop valve prevents hydraulic oil leakage when switching from a breaker to a bucket.
5. Pipe joints are constructed with multi-layer welding to minimize the risk of leaks.
6. The cylinder guard is designed to prevent damage in the event of a collision.
7. Our services are available at factory prices, offering customization options like ODM and OEM services.

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).
