Product Description-------Excavator Telescopic Boom
What is an excavator telescopic arm?
An excavator telescopic arm is primarily composed of a fixed body, a sliding body, a steel wire rope, and a telescopic cylinder. By adjusting the number of sliding bodies, it provides an optimal working radius and vertical excavation range. Typically paired with a bucket, this tool is effective for deep excavation tasks such as digging up soil, sand, or coal.
Three-section Telescopic Arm
* Centralized lubriPCion
* Adopt 30mm main rope, Adopt 26mm auxiliary rope
* Can design to match bucket and grabber
* The upgraded auxiliary rope design makes the pipeline smoother while stretching
* The external hose pulley separates the hose from the main rope, avoids the friction between the main rope and the hose, reduces failures, and makes maintenance more convenient
Advantages of telescopic arms:
2. We use 6mm thickness.
3. The slider is made of nylon and the pulley is made of steel.All hoses are centrally lubriPCed.
4. The external hose pulley of the bucket cylinder is more convenient for hose replacement and repair.
5. The external hose pulley separates the hose from the main rope.Avoid friction between the main rope and the hose, reduce failures.
6. The double rope design ensures the safety of the telescopic arm. Even if the main rope is broken, the arm will not stretch.

Configuration includes: Clamshell bucket 1pc , 2pcs Pin, Bidirectional foot switch 1pc
The first option is the clamshell bucket, which is commonly used for deep excavation projects like subway construction.
Next, we have the grab bucket, which, in contrast to the clamshell bucket, is more powerful and capable of grasping materials like stone.
Finally, there’s the standard bucket, specifically designed for use with telescopic booms, requiring custom design modifiPCions.
