At YLCM, we believe the integrity of your machinery begins with its frame, which is why we have spent over 22 years establishing ourselves as a premier excavator structural component manufacturer. Operating as a world-class structural component factory and strategic OEM partner, we engineer reinforced steel solutions—including booms, arms, and mainframes—that serve as the indestructible "skeleton" of your equipment. By utilizing high-tensile materials like Q355B and Hardox steel combined with advanced robotic welding and 100% ultrasonic flaw detection, we produce precision-engineered components for Komatsu, Caterpillar, Hitachi, and Volvo that endure the immense stress of rock breaking and heavy lifting. Whether you are a global wholesaler of undercarriage frames or a contractor in need of a custom-built long-reach boom, our high-capacity factory bridges the gap between standard replacement and reinforced performance. We are committed to providing wholesale solutions with factory-direct pricing, ensuring every OEM structural part offers a perfect fit and mining-grade durability for the most demanding job sites.
