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.
This shorter arm allows for greater maneuverability in tight spaces, making it easier to excavate and move material without hitting walls or other obstacles.

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.

 

 

Advantages of Zhonghe Machinery

2. Automated processing equipment. Automatic cutting and double-sided floor-standing large boring machine etc.

3. Industry standard welding technology, carbon dioxide shielded welding, good weld crack resistance.

4. Strict and meticulous quality inspection, ultrasonic flaw dete

 

 

 

 

 

 

Special design----meet customer needs !!!

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 Zhonghe Machinery :

Kaiping Zhonghe Machinery Co.,Ltd. established in 2018, it is a combination of manufacturing and trading, specializing in customizing different kinds of excavator boom arms and attachments. We are located in cuishanhu New District. Kaiping cityJiangmen City. Guangdong Province, China. We boast a 21000m3 steel structure workshop with a large number of high precision processing equipment and a strong and cohesive team of over 100 experienced technical staff. 50 welding workers with over 7 years experience. 30 senior designers, and a high-tech R&D team(10+ years on customization.100+technical patents), strict production system(6+ years quality control and cost control) and warm-hearted service team. Our annual output of various types of excavator boom arms can reach up to 800 sets.

 

Production Using High-precision Instruments

Plasma cutting machine

Plates less than 30mm thick are plasma cut, while those over 30mm are flame cut. Plasma cutting deformation is 0.1 mm.CNC plasma cutting with less panel deformation.

 

 

 

Double sided boring machine

Improved accuracy and consistency: Since the boring pin operations on both sides of the double-sided boring machine are performed simultaneously, the machining accuracy and consistency on both sides can be guaranteed.

 

 

 

  •  
  • 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 a complete range of production equipment, which is conducive to the production of our products, good quality and ensures product accuracy.

 
1. Panel is cut by CNC plasma machine with less deformation.
2. Tolerance within 5-10um, ensure the accuracy of hole .
3. Environmentally friendly verified spraying room.
4. GMAW-Gas Metal Arc Welding.
5. Plasma cutting machines, boring machines, beveling machines, bending machines, etc. ensure accuracy.

 

Q1: Are you a manufacturer?

A1: Zhonghe machinery offered a wide range of attachment attachments for excavators . Such as long reach arm, demolition 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 a moderate price is the key to the 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 tunnels. Each country has a different name, but in China we call them tunnel arms.
 
Q3: What are the configurations of tunnel arms?
A3: According to the height of the tunnel, you can design configurations that require or do not require a boom cylinder, but the necessary configurations are: one arm cylinder, one bucket cylinder, 8 pins, 6 high-pressure hoses, a set of connecting rod assemblies, a set of breaker pipes, and 2 stop valves. The general operating height of tunnel arms is 4-6 meters.
 
Q4. What are the requirements for tunnel arms?
A4: A. It is recommended that the tunnel arm be equipped with a straight hammer. The basement has a limited height. When operating, part of the triangular hammer is higher than the plane of the arm, which will scrape the top and make the operation inconvenient. The straight hammer will not have this problem. B. The design of the tunnel arm does not take into account the transportation height. Generally, the transportation of the tunnel arm of a large machine requires the removal of the breaker before transportation. The forearm of the tunnel arm is filled with materials to increase the weight of the tunnel arm, press down the breaker hammer, reduce the rebound force of the breaker hammer, and increase the crushing force.
