The slewing arm is integrally welded and formed from high-strength wear-resistant alloy steel plates. It features a rational structural design, high overall rigidity and excellent slewing stability. Key stress-bearing sections are thickened and reinforced with exquisite welding technology. Subjected to stress relief treatment, it delivers great torsion resistance and anti-deformation performance. Boasting impact resistance, fatigue resistance and high load capacity, it adapts to multi-angle slewing working conditions of construction machinery. With stable operation and long service life, it serves as the core load-bearing structural component for equipment slewing operation.
