Benefits of Telescopic Dipper Arms Latest Telescopic Dipper Arm Models Installation Guide for Excavator Sliding Arms
Telescopic Boom/Sliding Arm Features
The sliding arm facilitates the excavation of deep wells, foundation pits, tunnels, sewage systems, and other municipal works.
Our establishment dates back to 2018, and we have accumulated over 6 years of experience in the industry. Our engineering team boasts more than 10 years of expertise in designing and customizing long arms for various excavator brands.
Our product is compatible with all excavator models, and we provide OEM services.
We adhere to an advanced manufacturing process that meets international technology standards.
We have comprehensive installation dimensions for most excavators and can tailor this long arm to fit your equipment.
Before we weld, we mill the edges of the steel plate using a large milling machine (taper processing), ensuring the welding penetrates the steel for improved structural performance. We also include reinforcement plates for durability.
If necessary, we can add extra pipes for specific additional functions.
Our long boom allows you to use your original arm cylinder, thereby saving costs. If you require a new cylinder, we can provide that too.
For heavy-duty applications, some parts can be reinforced using thicker plates or by overlapping additional plates.
We utilize shielded gas welding, employing a mixture of 80% argon and 20% carbon dioxide, which is recognized as the industry 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).
