In construction operations, a long reach boom excavator plays a vital role in efficient digging tasks. Unlike standard boom arms, the excavator long arm extends further, allowing operators to reach more expansive areas without the need to reposition the machine. This versatility makes the long boom excavator ideal for various brands of excavators, enhancing their functionality. It's particularly effective for excavating materials such as sand, soil, silt, and gravel. The long boom excavator is commonly utilized for tasks like river cleaning, dredging, and unloading goods at jetties. Key stress points are reinforced to ensure the long boom operates effectively while minimizing maintenance downtime. Each set of the long arm, such as those compatible with Komatsu models, is crafted from Shaogang Q355B steel, known for its superior welding performance and resistance to cracking.
