High-Quality Excavator Boom for Sale Hydraulic Sliding Arm forExcavator Adjustable Excavator Boom Heavy-Duty Sliding Arm
Telescopic Boom/Sliding Arm Features
The sliding arm is utilized for excavating deep wells, foundation pits, tunnels, and sewage systems in municipal projects.
Founded in 2018, our team brings over 6 years of experience. Our engineers possess over 10 years of expertise in creating customized long arms for various brands of excavators.
This product suits all excavator models, and we provide full OEM services.
Our advanced manufacturing processes meet global technology standards.
We have comprehensive installation specs for most excavators, allowing us to tailor this long arm specifically for your machine.
We utilize a large milling machine to mill the edges of steel plates before welding, ensuring a strong bond through deeper penetration. Reinforcement plates enhance the internal strength.
We can add extra pipes as necessary for specialized applications.
The long boom allows you to use your original arm cylinder to reduce costs; if needed, we can provide a new one.
Some parts can be enhanced with thicker plates or additional overlapping plates for heavy-duty use.
Our welding technique employs shielded gas welding, using an 80% argon and 20% carbon dioxide gas mixture, which is considered the gold standard.
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).
