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: 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.
