Zhonghe Factory Advantages of Long Reach Boom/Long Arm:
What is the purpose of a long arm plate bevel?
Welding machines commonly used in the industry have a depth of fusion of only 3mm thick, and our long arm plate is at least 8mm thick. Our long arm plates are at least 8mm thick, and without a bevel, the welder cannot penetrate the entire weld, resulting in poor weld results and problems such as cracking of the weld at a later stage.
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.
