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.

Q355B Hydraulic Excavator Short Arm Tunnel Boom Wear Resistant 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).

Large Floor-Standing Double-Sided Boring and Milling Lathe:

  • Improved Accuracy and Consistency: The double-sided boring and milling lathe enhances the precision and uniformity of operations, ensuring consistent results.
  • Post-Welding Processing: After the welding process, the machine performs overall boring, ensuring the parallelism and perpendicularity of shaft holes.
  • Primary Applications: Primarily used for post-weld boring of the boom, small arm, and bucket, ensuring the accuracy and proper alignment of the boom.
  • Simultaneous Boring on Both Sides: The lathe performs boring on both sides at the same time, guaranteeing identical precision and consistency on both sides.

FAQ(Some frequently asked questions):

Q1: Are you a manufacturer?

A1: Zhonghe Machinery provides a wide variety of attachments for excavators. Such as long arms, demolition arms, telescopic arms, standard buckets, rock buckets, cleaning buckets, tilt buckets, etc. We know that the perfect combination of high-quality cast steel products and moderate prices is the key to success.

Q2: Why is it called a tunnel arm?

A2: Tunnel arms generally refer to working devices that operate in narrow spaces. Most of them operate in tunnels, so they are called tunnel arms. Each country has a different name, but in China we call it a tunnel arm.

Q3: What are the configurations of the tunnel arm?
A3: Depending on the height of the tunnel, the configuration that requires or does not require the boom cylinder can be designed, but the necessary configurations are: one boom cylinder, one bucket cylinder, 8 pins, 6 high-pressure hoses, one set of connecting rod assemblies, one set of crushing pipes, and 2 stop valves. The general operating height of the tunnel arm is 4-6 meters.

Q4: What are the requirements for the tunnel arm?
A4: A. It is recommended that the tunnel arm be equipped with a straight hammer. The basement height is limited. During operation, the triangular hammer part is higher than the arm plane, which will scrape the top and make the operation inconvenient. The straight hammer will not have this problem. B. The tunnel arm design does not take into account the transportation height. Generally, the transportation of large-scale mechanical tunnel arms requires the breaker to be removed before transportation. Filling materials in the forearm of the tunneling arm increases the weight of the tunneling arm, presses down the breaker, reduces the rebound force of the breaker, and increases the crushing force.
