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 lubrication
* 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:
1.The three-section telescopic boom is made of BS900E, and Q355B,
which is lighter and more durable.
2. We use 6mm thickness.
3. The slider is made of nylon and the pulley is made of steel.All
hoses are centrally lubricated.
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
Our designs enable the versatile use of both digging and grab
buckets.
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 modifications.
