The excavator undercarriage frame is integrally forged and welded from high-strength alloy steel, featuring high overall structural rigidity and excellent load-bearing performance.The thickened main beam and reinforced side plates are integrally formed, with great torsion resistance, impact resistance and deformation resistance.It adapts to harsh working conditions such as mines and construction sites. With large load capacity, high operation stability, corrosion resistance and fatigue resistance, it is the core basic structural part for excavator traveling and load bearing.
