Advantages of Tunnel Arm Modification:

1. 1. Modifying the tunnel arm expands its operational range to fit various job sites, reducing the risk of the boom impacting tunnel or basement beams.

3. 2. Following the modification, excavators can utilize larger breakers; for example, a PC120 can now support a 135 breaker, and a PC200 can use a 165 breaker. This change requires enhanced double pump confluence to increase impact force significantly.

5. 3. A shorter boom design allows for a greater torque reduction, enabling the tunnel boom to lift larger buckets more effectively.

7. 4. The incorporation of a stop valve when replacing the breaker with a bucket prevents any potential hydraulic oil leakage.

9. 5. Pipe joints are reinforced with multi-layer welding to effectively decrease oil leak risks.

11. 6. A protective cylinder guard minimizes the likelihood of damage from collisions.

13. 7. Our modification services come at factory-direct prices, ensuring affordability along with options for ODM and OEM customization.

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.
