South Africa stands as a global hub for mining and heavy industrial activity. From the deep gold mines of the Witwatersrand to the vast iron ore pits in the Northern Cape, the demand for high-strength Excavator Track Bolts is critical. In the local South African market, machinery operates under some of the harshest abrasive conditions in the world.
As a leading manufacturer, Quanzhou Hesen Machinery provides the precision-engineered bolts required to withstand the high torque and sheer stresses common in South African earthmoving operations.
Utilizing 40Cr and 35CrMo steel with specialized heat treatment to ensure core toughness and surface hardness for SA rocky terrains.
Our factories employ automated optical inspection (AOI) to ensure every thread on our track bolts meets 100% precision requirements.
Designing bolts specifically for the high-sulfur and high-moisture environments found in KwaZulu-Natal’s coastal construction projects.
Our products are engineered to serve the diverse industrial landscape of the Rainbow Nation:
Large-scale excavators (CAT 349, Komatsu PC800) require track bolts that can handle 24/7 vibration. Our high-strength bolts prevent track shoe loosening, a major cause of chain failure in coal mines.
In the rapid expansion of Sandton and Midrand, medium excavators utilize our PC200 and E320 series bolts for efficient roadwork and foundation digging where reliability is key to meeting tight deadlines.
Founded in 1990, Quanzhou Hesen Machinery Industry Co., Ltd has evolved into a powerhouse in the undercarriage parts industry. With over 30 years of experience, we specialize in high-strength bolts, nuts, bucket teeth, and comprehensive undercarriage solutions for international markets, including a strong presence in South Africa.
Our facility spans 200,000+ square meters and is staffed by over 1,200 employees, including 65+ dedicated R&D engineers who constantly innovate to meet the evolving needs of global construction and mining sectors.
