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:
- Urban Redevelopment: The telescopic arm is perfect for urban redevelopment projects, allowing for work in restricted areas without excessive equipment movement.
- High-Demand Excavation: Its flexibility makes it suitable for excavation tasks that require precision and depth.
- Tight Construction Sites: The arm works effectively in tight construction sites where standard equipment would be cumbersome.
- Underground Utilities: It can reach deep underground for utility installations in urban settings.
- Dismantling Structures: The telescopic arm is beneficial for dismantling and demolition tasks in urban environments.
- Site Preparation: Its extendable features make it valuable for site preparation tasks that require depth and reach.
- Pavement Removal: The arm can efficiently remove pavement or concrete in restricted spaces.
- Water Management Projects: It is useful in projects requiring excavation in wet or waterlogged 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).
Large Floor-Standing Double-Sided Boring and Milling Lathe:
- Improved Accuracy and Consistency: The double-sided boring and milling lathe enhances the precision and uniformity of operations, ensuring consistent results.
- Post-Welding Processing: After the welding process, the machine performs overall boring, ensuring the parallelism and perpendicularity of shaft holes.
- Primary Applications: Primarily used for post-weld boring of the boom, small arm, and bucket, ensuring the accuracy and proper alignment of the boom.
- Simultaneous Boring on Both Sides: The lathe performs boring on both sides at the same time, guaranteeing identical precision and consistency on both sides.
