Excavator Tunnel Arm/Short Arm Details
An excavator's tunnel arm, often referred to as a short arm or short boom, is a specialized attachment used in confined spaces like tunnels or underground environments where a standard excavator boom might be too long or unwieldy.
Key Features of a Tunnel Arm/Short Arm:
* Shorter Length: Designed specifically to work in confined spaces, providing greater control and reducing the risk of accidental
damage.
* Increased Durability: Often reinforced to handle the stress of working in challenging environments.
* Enhanced Precision: Allows for more precise digging and material handling, crucial in environments where space is limited.
* Compatibility: Can usually be attached to various types of excavators, depending on the model and manufacturer.
This shorter arm allows for greater maneuverability in tight spaces, making it easier to excavate and move material without hitting walls or other obstacles.

What are the advantages of modifying the tunnel arm?
1. The operating range is adapted to the working conditions, and there is no need to worry about the arm hitting the beams of the tunnel or basement.
2. After modifying the tunnel arm, because the arm is shortened, a larger breaker can be used. 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 the double pumps, and the impact force is doubled.
3. The tunnel arm can carry a bucket. The arm is shortened, the torque is shortened, the force is greater, and a larger bucket can be carried.
4. Stop valves prevent oil leakage when replacing breaker by bucket.
5. Multi-layer welding of pipe connectors to reduce the risk of oil leakage.
6. Cylinder protective cover is beneficial to preventing the cylinder from being damaged in collision.
7. Factory price, cheap price, support customization, ODM or OEM service.
Excavator Tunnel Arms Suitable For Application
What is the role of beveling the long arm plate?
The melting depth of the welding machine commonly used in the industry is only 3mm thick. The plate thickness of our long arm is at least 8mm. If the beveling is not opened, the welding machine will not be able to penetrate the entire weld, so the welding effect will be poor, and the weld cracking and other problems will occur later.
We use machinery to make the bevel, while other factories use manual bevel (as shown in the picture)
About Our Company------Zhonghe Machinery
Q1: Why is it called a tunnel arm?
A2: Tunnel arm usually refers to a working device that operates in narrow spaces. Most of them operate in tunnels, hence they are called tunnels. Every country has a different name, but in China we call it tunnel weapons.
Q2: Are you a manufacturer?
A2: Zhonghe Machinery provides various accessories for excavators. Such as long arm, dismantling arm, telescopic arm, standard bucket, rock bucket, cleaning bucket, tilting bucket, etc. We know that the perfect combination of high-quality cast steel products and moderate prices is the key to success.
Q3. What are the requirements for tunnel arms?
A3: A. It is recommended to equip the tunnel arm with a straight hammer. The height of the basement is limited. When operating, a part of the triangular hammer is higher than the plane of the arm, which can scratch the top and make the operation inconvenient. A straight hammer won't have this problem. B. The design of the tunnel arm did not take into account the transportation height. Generally speaking, the tunnel arm for transporting large machinery requires the removal of circuit breakers before transportation. The forearm of the tunnel arm is filled with material to increase the weight of the tunnel arm, press down on the breaking hammer, reduce the rebound force of the breaking hammer, and increase the breaking force.
Q4: What are the requirements for tunnel robotic arms?
A4: Answer: It is recommended to equip the tunnel arm with a straight hammer. The height of the basement is limited. During the operation, the triangular hammer part is higher than the arm plane and may scratch the top, causing inconvenience to the operation. However, a straight hammer will not have this problem. B. The tunnel arm design did not take into account the transportation height. Generally speaking, the transportation of large mechanical tunnel arms requires the dismantling of the breaking hammer before transportation. Filling the material in the forearm of the excavation arm will increase the weight of the excavation arm, compress the crushing hammer, reduce the rebound force of the crushing hammer, and increase the crushing force.
