Product Description-------Excavator Telescopic Boom
What is an excavator telescopic arm?
An excavator’s telescopic arm is an attachment that offers adjustable reach. With its ability to extend and retract, it is ideal for projects requiring precise positioning, such as trenching or construction in confined areas.
What are your advantages?
Advantages of telescopic arms:
1. Our three-section telescopic boom, constructed from BS900E and Q355B, balances lightness with strength.
2. We implement a durable 6mm thickness for superior resilience.
Nylon sliders paired with steel pulleys and centrally lubricated hoses promote efficient operation.
3. An external pulley on the bucket cylinder facilitates easy hose repairs and replacements.
4. The design keeps hoses separate from the main rope, reducing friction and maintenance needs.
5. The arm’s safety is reinforced by a double-rope system, ensuring it won’t extend if the main rope is compromised.

The telescopic arm of the excavator is suitable for the following working conditions:
- Confined Workspaces: The telescopic arm excels in confined workspaces, making it ideal for projects in cities or narrow lots.
- Vertical Excavation: It is effective for vertical excavation tasks, such as digging deep foundations or basements.
- Precision Demolition: The arm’s reach allows for precision in demolition tasks, minimizing collateral damage.
- Utility Trenching: It is well-suited for trenching for utility installations where space is limited.
- Maritime Applications: The telescopic arm can be adapted for use in maritime construction, reaching areas that are difficult to access.
- Heavy Lifting in Restricted Areas: The arm is useful for lifting heavy materials in areas with limited access.
- Agricultural Applications: It can be employed in agricultural projects that require excavation or material handling in confined spaces.
- Environmental Remediation: The arm is beneficial for environmental cleanup tasks, reaching areas that are otherwise challenging to access.

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.
