Application of Extended Arm
The extended arm is a staple in diverse construction applications, including river dredging, port operations, subway construction, and foundation excavation. Renowned for its exceptional efficiency and safety, it excels in a myriad of operations. When the standard arm falls short of reaching extended and deeper digging distances, the River-produced long reach boom emerges as a pivotal solution, enhancing productivity to meet the demands of challenging projects.

The Advantages of River’s long reach boom
- Cutting-Edge Manufacturing and Processing Capabilities: As a distinguished Long Reach Boom manufacturer, we boast a comprehensive suite of advanced processing and manufacturing equipment, including laser cutters, plasma cutters, welding robots, and automatic coating lines. This arsenal ensures the precision of our products, guaranteeing both excellence and high production efficiency.
- Premium-Quality Raw Steel Materials: Our commitment to excellence extends to sourcing raw materials exclusively from China’s top steel manufacturers. The extension arm, crafted from low-alloy high-strength plates with commendable tensile strength, is pivotal for optimizing the efficiency of excavators. Notably, our hydraulic hoses undergo phosphating for superior anti-corrosion and anti-rust properties, safeguarding the hydraulic system from contaminants. The use of copper sleeves on connectors, in place of the commonly used steel sleeve, further underscores our dedication to quality.
- Advanced Computer-aided Design Tools: Employing state-of-the-art CAD, 3D, and FEA structural design tools, our adept design team provides accurate data analysis for secondary development and personalized customizations. This technological prowess not only facilitates product upgrades but also minimizes production timelines. Addressing concerns of potential cracking and breaking, our innovative designs prioritize the longevity and reliability of our long arms.
- Stringent Production Processes for Unwavering Quality: At every juncture of the production process, meticulous controls are implemented to guarantee the delivery of products of the highest quality. Our unwavering commitment to strict quality control ensures that our customers receive consistently reliable and top-tier products.
