Affordable Long Arm Excavator Attachments Custom Excavator Long Boom Fast Shipping for 6-50ton excavator
The extended arm (also known as long arm) is a special attachment for excavators or other heavy machinery. It extends the operating radius and height of the excavator to expand its operating range. The extended arm is widely used in engineering projects that require a larger operating radius or depth, such as river dredging, high-rise building demolition, deep excavation, and difficult slope finishing tasks.

The main functions and features of the extended arm:
The main functions and features of the extended arm:
1. Expanded operating range: Compared with the standard excavating arm, the extended arm significantly increases the excavator's operating range and can penetrate deeper or higher into areas.
2. Wide application: suitable for various engineering operations such as river cleaning, mountain excavation, and high-rise building demolition.
3. Enhanced stability: Although the length of the excavation arm is lengthened, the special design ensures the balance and stability of the equipment, ensuring efficient and safe operation.
4. Suitable for a variety of excavator attachments: The extension arm can be matched with a variety of attachments, such as buckets, hydraulic shears, grabbers, etc., to meet different work needs.
5. Durability: The extension arm is usually made of high-strength materials, has good wear resistance and durability, and can adapt to complex and harsh working conditions.

Zhonghe Factory Advantages of Long Reach Boom/Long Arm:
What is the purpose of a long arm plate bevel?
The purpose of a long arm plate bevel is to facilitate the welding process, ensuring a stronger and more reliable weld that extends through the full thickness of the material. Here are the key reasons for using a bevel on a long arm plate:
Improved Weld Penetration: As you mentioned, welding machines typically have a depth of fusion that is less than the thickness of the plate. A bevel allows the welding arc to reach further into the material, achieving better penetration and ensuring that the weld fills the entire joint.
Preventing Weld Cracking: Without a bevel, the weld may not penetrate fully, leaving a weak spot in the weld that could lead to cracking under stress. A proper bevel ensures that the weld is continuous and free of defects that could cause future failures.
Reducing Welding Time: A beveled edge can reduce the amount of material that needs to be melted, which can decrease the time required to complete the weld.
Enhancing Weld Quality: The bevel provides a consistent edge for the welder to work with, which can lead to a more uniform and aesthetically pleasing weld.
Mechanical vs. Manual Beveling: Mechanically cutting bevels is generally more precise than manual methods. This precision is critical for ensuring the quality of the weld. A mechanically cut bevel provides a cleaner, more uniform edge that can be more easily and consistently welded.
Factories that use mechanical beveling over manual beveling often produce products with higher quality and consistency. The mechanical process reduces human error and provides a more reliable bevel that is critical for structural integrity, especially in heavy-duty equipment like excavator long arm plates.
We make bevels mechanically, while other factories make bevels manually (as shown in the picture)
Main features of extended excavator arms:
Wider operating range: Compared with standard excavator arms, extended arms can dig deeper or farther, suitable for large areas or high-altitude operations.
Wide application: Extended arms are widely used in river dredging, mountain restoration, high-rise building demolition and other fields.
Strong stability: Although the extended arm expands the excavation range, its design maintains the balance and operational stability of the equipment, which is particularly suitable for large-scale operations.
Adapt to complex working conditions: In underwater operations or difficult demolition projects, extended arms can achieve precise operations and adapt to various complex environments.
Customizable design: Extended arms can usually be customized according to project requirements, such as arm length, strength, required special accessories, etc.
