In construction projects, a long reach boom excavator is essential for efficient digging. Its extended arm allows it to access larger areas compared to a standard boom arm, eliminating the need for the operator to reposition the excavator. Long boom arms are compatible with various brands of excavators and are ideal for excavating materials such as sand, soil, silt, and gravel. Additionally, these excavators are commonly employed for tasks like river cleanup, dredging, and unloading goods at jetties. Areas subjected to significant stress are reinforced, enhancing the operational efficiency of the long boom excavator and reducing maintenance time. One set of the long arm excavator for Komatsu is constructed from Shaogang Q355B steel, which offers superior welding capabilities and resists cracking.
