The excavator arm is precisely welded from high-strength alloy steel plates, featuring high overall structural stiffness and excellent bending and torsion resistance. Key stress-bearing areas are thickened and reinforced with uniform and firm welds, delivering impact resistance, fatigue resistance and anti-deformation performance. It is suitable for complex working conditions such as earthwork excavation and mine heavy-load operation. With large load capacity, stable and reliable operation and long service life, it is an important core structural part of the excavator working device.
