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.
|| Excavator Tunnel Arms Suitable For Application
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).
|||About Our Company------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
Plate thickness less than 30 mm is cut with a plasma cutter, and plate thickness greater than 30 mm is cut with a flame cutter. Plasma cutting typically causes 0.1 mm deformation, while CNC plasma cutting minimizes panel deformation.
Double-sided boring machine
Improve precision and consistency: Double-sided boring machine can perform boring operations on both sides at the same time, ensuring that both sides maintain processing accuracy and consistency.
Milling Machine
The milling machine is used for machining wear blocks, positioning pipe clamps and drilling holes. It ensures high precision and the drilling error is kept within 5-10 microns. Its precise design helps to evenly distribute the force, which helps to extend the service life of the components.
Beveling Machine
Beveling machines are used to prepare the plate edges for welding and are an initial step in the welding process. We use mechanical beveling rather than flame beveling, leaving only 2mm of plate thickness for beveling. This method ensures better fusion between the plate and the weld material. By beveling the edges, the welding machine can achieve full penetration of the weld, reducing the risk of problems such as weld cracking.
Our factory is equipped with comprehensive production machinery, which supports the manufacturing of high-quality products with precise specifications.
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.
