Main functions and features of the extension boom:
1. Expanding operation range: compared with the standard digging arm, the extension arm greatly increases the operation range of the excavator, which can go deeper or deeper into the higher area.
2. Wide range of application: It is suitable for various engineering operations such as river cleaning, mountain excavation and high-rise building demolition.
3. Enhanced stability: Although the length of the excavator arm is lengthened, the special design ensures the balance and stability of the equipment, which guarantees efficient and safe operation.
4. Applicable to a variety of excavator attachments: the extended arm can be matched with buckets, hydraulic shears, grapples and other attachments to meet different operational needs.
5. Durable: Extension arms are usually made of high-strength materials, with good wear resistance and durability, and can adapt to the complex and harsh working environment.

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 that the weld is stronger, more reliable, and penetrates the entire thickness of the material. Here are the main reasons to use a bevel on a long arm plate:
- Improves weld penetration: As you mentioned, the depth of fusion of a welding machine is usually less than the thickness of the plate. The bevel allows the welding arc to penetrate further into the material, achieving better penetration and ensuring that the weld fills the entire joint.
- Prevents weld cracking: Without a bevel, the weld may not penetrate fully, leaving weak spots in the weld, which can cause cracking under stress. A proper bevel ensures that the weld is continuous and free of defects that can cause future failures.
- Reduces welding time: A beveled edge can reduce the amount of material that needs to be melted, which can reduce the time it takes to complete a weld.
- Improves weld quality: A bevel provides a consistent edge for the welder, which can result in a more even, better looking weld.
- Mechanical bevel vs. manual bevel: Mechanically cut bevels are generally more precise than manual methods. This precision is critical to ensuring a quality weld. Mechanically cut bevels provide a cleaner, more uniform edge that allows for easier and more consistent welding.
Shops that use mechanical bevels typically produce a higher quality, more consistent product than manual bevels. The mechanical process reduces human error and provides a more reliable bevel, which is critical for structural integrity, especially in heavy equipment such as excavator long boom plates.
We make bevels mechanically, while other factories make bevels manually (as shown in the picture)

Working Scene of Excavator Long Reach Boom Arm
Main features of extended arm excavator:
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.

High precision machine of Zhonghe Machinery Manufacturers
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.

FAQ(Some frequently asked questions):
Q: Are you a manufacturer?
A: Zhonghe machinery offered a wide range of attachment parts for excavators and dozers. Such as long reach arm, demolition arm, telescopic arm, standard bucket, rock bucket, cleaning bucket, tilting bucket, etc. We know that the perfect combination of high-quality cast steel products and a moderate price is the key to the success.
Q: What material is the excavator long arm made of?
A: Shaogang Q355B, Shaogang's material has the advantages of good toughness, high welding performance, and not easy to crack. Q355B has good welding performance and can be processed at room temperature. The standard arm material of the host manufacturer is also Q355B, which is easier to purchase on the market and the subsequent maintenance cost is also simple. If the customer's working conditions are bad, we will also use Q690 material, the long arm will be made lighter and more efficient
Q: Why choose Zhonghe over other companies?
A: We offer a highly skilled production and design team that delivers high-quality, customized solutions tailored to each customer’s needs. Our commitment to precision and customer service has earned us a strong reputation in China, with annual sales consistently ranking among the top in the industry.
