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.
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.
About Our Company------Zhonghe Machinery
Q1: Are you a manufacturer?
A1: Zhonghe Machinery provides a diverse selection of attachments for excavators, including long reach arms, demolition arms, telescopic arms, standard buckets, rock buckets, cleaning buckets, tilting buckets, and more. We understand that the key to success lies in offering high-quality cast steel products at competitive prices.
Q2: Why is it called a tunnel arm?
A2: Tunnel arms refer to equipment designed for operations in confined spaces, typically within tunnels. Because they often work in such environments, they’re commonly known as tunnel arms. The terminology may vary by country, but in China, we call them tunnel arms.
Q3: What are the configurations of tunnel arms?
A3: Depending on the tunnel’s height, you can design configurations that either require or omit a boom cylinder. However, essential components include: one arm cylinder, one bucket cylinder, 8 pins, 6 high-pressure hoses, a set of link assemblies, a set of breaker pipes, and 2 stop valves. Tunnel arms typically operate at heights of 4-6 meters.
Q4: What are the requirements for tunnel arms?
