I. Advantages of Excavator Tunnel Arm

1. Enhanced maneuverability in tight spaces
Tunnel arms are designed for tight spaces, allowing excavators to operate efficiently in areas where standard arms are difficult to operate, such as tunnels, subways, or basements.
2. Reduced risk of damage
The compact design minimizes the possibility of the boom hitting overhead beams or walls, making it ideal for environments with limited clearance.
3. Accommodate a variety of attachments
Tunnel arms can be equipped with a variety of tools, such as crushers, buckets, or hammers, depending on the specific needs of the project. This flexibility increases the versatility of the excavator.
4. Improved force application
The shortened boom allows for greater force concentration, allowing for the use of larger crushers and buckets. This enhances the machine's ability to handle heavy tasks such as crushing and material removal.
5. Improved stability
Tunnel arms typically have added weight on the forearm, which helps stabilize the machine and reduces bounce when using a crusher. This makes operations more efficient and precise.
6. Customizable configurations
Depending on the size of the tunnel, tunnel arms can be customized to include or exclude specific components (such as boom cylinders) to meet operational needs.
7. Hydraulic Component Protection
Many tunnel booms have features such as cylinder guards to protect important components from damage when operating in narrow or rugged environments.
8. Easy to Transport
While some larger tunnel booms need to be disassembled for transport, the compact design makes it easier to move the equipment compared to a standard long boom.
9. Improved Operator Safety
By reducing the likelihood of collisions with surrounding structures, tunnel booms help improve operational safety, protecting both the machine and the operator.

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 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).

  • Milling machine
  • responsible for milling wear-resistant blocks, positioning of pipe clamps, etc., used for boring holes. The product precision is strict, the drilling error is within 5-10um, and the precise and accurate design can make the force more balanced, thereby extending the service life.

Beveling machine

It is responsible for the beveling of the plate, which is the first process before welding. Mechanical beveling is used instead of flame beveling, and only 2mm plate thickness is reserved for beveling, so that the plate and welding material can be better welded. By beveling, the welding machine can penetrate the entire weld, and it is not easy to cause problems such as weld cracking.

Our factory has complete production equipment, which is conducive to the production of our products, good quality and guaranteed product accuracy.

1. The panel is cut by CNC plasma machine with small deformation.
2. The tolerance is within 5-10um to ensure the accuracy of the hole.
3. Environmentally verified paint room.
4. GMAW-gas shielded metal arc welding.
5. Plasma cutting machine, boring machine, beveling machine, bending machine, etc. to ensure accuracy.

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.
