Application of Extended Arm
An extended arm is commonly used in construction activities such as river dredging, port work, subway work, foundation excavation, and others. With high efficiency and safety, it performs a wide range of operations. It is possible to improve productivity with a long reach boom produced by the river if the standard arm cannot be able to reach farther and longer digging distances.

The Advantages of River’s long reach boom
1.Excellent Manufacturing and Processing Capabilities
As a manufacturer, we have a complete set of advanced processing and manufacturing equipment such as laser cutters, plasma cutters, welding robots, automatic coating lines, etc., capable of ensuring the fineness of products and a high level of production efficiency.
2. High-Quality Raw Materials
All steel materials are from China’s top steel manufacturers of reputable companies, and the extension arm is made of low-alloy high-strength plates with good a tensile strength. Choosing the right materials for the boom and arm, as the most critical components on an excavator, directly affects the work efficiency.
It is also important to note that all hydraulic hoses are phosphated, which has excellent anticorrosion and antirust properties, and which can effectively protect the hydraulic system against contamination. Instead of the steel sleeve commonly used in the market, the copper sleeve is used on the connector.
3.Advanced Computer-aided Design Tools
With the use of CAD, 3D, and FEA structural design tools, our professional design team can provide accurate data analysis for secondary development and private customized products. In addition, they can upgrade products based on originality, thereby reducing production times. The risk of cracking and breaking of the long arms have also been taken care of.
4.Strict Production Process to Ensure Stable Quality
Every aspect of the production process is strictly controlled to ensure the highest quality products are delivered to our customers.
