Telescopic Boom/Sliding Arm Summary
The sliding arm plays a key role in excavating deep wells, foundation pits, tunnels, and sewage pipelines for municipal applications.
Since our founding in 2018, we have gained over 6 years of industry expertise. Our engineers have more than 10 years of experience in designing and customizing long arms for various excavator brands.
This product is designed to be compatible with all excavator models, and we offer comprehensive OEM services.
Our advanced manufacturing processes are aligned with international standards.
We maintain installation dimensions for most excavators, allowing us to customize this long arm to your specifications.
Before we proceed with welding, we utilize a large milling machine to mill the edges of steel plates, ensuring that the weld penetrates deeply for enhanced performance. Reinforcement plates are included for added durability.
If necessary, we can add additional pipes for specific applications.
You can save costs by utilizing your existing arm cylinder with our long boom; if you require a new cylinder, we can prepare that for you as well.
Some components can be fortified with thicker plates or by overlapping additional plates for heavy-duty applications.
Our welding process uses shielded gas welding, employing a mixture of 80% argon and 20% carbon dioxide, which is the recognized standard in the industry.
EXCAVATORS WITH A TELESCOPIC ARM
(UPPER ARM SLIDING TYPE)
1. Thanks to the hydraulic sliding system in this model, the arm contracts and expands (‘telescopes’) speedily, providing high working efficiency.
2. Sliding mechanisms using rollers on the slide surfaces makes adjustment easy and prevents vertical and horizontal vibrations of the arm, which in turn minimises the wear which shortens arm life.
3. With the arm extended, the excavator can dig to the same depth as machines three (3) classes higher, so this becomes a useful attachment for restricted job sites where a wide working range is needed.

What is the purpose of beveling the long arm/tunnel 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).
