Product Description-------Excavator Telescopic Boom
What is an excavator telescopic arm?
The excavator telescopic arm is a dynamic tool designed to improve the efficiency of excavation work. Its adjustable length allows operators to adapt to different job requirements, whether digging, lifting, or demolishing in challenging environments.
What are your advantages?
Advantages of telescopic arms:
1. Made with BS900E and Q355B, the three-section telescopic boom is designed to be both lightweight and sturdy.
2. A thickness of 6mm contributes to its enhanced durability.
The use of nylon for sliders and steel for pulleys, combined with centralized hose lubrication, ensures smooth operation.
3. The bucket cylinder’s external hose pulley simplifies the process of hose maintenance.
4. This design effectively separates the hose from the main rope to minimize friction and damage risks.
5. Featuring a dual-rope system, the arm remains safe even if the main rope fails, preventing unintended extension.

The telescopic arm of the excavator is suitable for the following working conditions:

What is the purpose of beveling the long boom 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).
