The Shanxi Jianing Forging Forging Train Wheel, Mine Overhead Wheel, and Heavy-Duty Overhead Wheel Forging Project features mature forging technology for high-strength wheels, excellent load-bearing performance, and suitable for heavy-duty conditions in rail transit and mines.
A forklift factory in Kaizhou, Chongqing, has set high requirements for the use of wheel forgings in heavy-duty operations. The plant has operated for a long time in complex mining environments, where wheel components frequently face high loads, gravel surfaces, and the impacts of continuous operation. Jianing Forging provided them with customized wheel forgings, which, after multiple rounds of process optimization and field validation, successfully met the customer's core requirements for durability and safety.
During the operation of mining forklifts, the original wheel forgings had the following prominent issues:
1. Rapid wear and tear, with an average replacement interval of less than 3 months, resulting in high maintenance costs;
2. During heavy heavy sharp turns or bumpy road sections, forgings are prone to microcracks, posing a risk of fracture;
3. Due to large dimensional tolerances and poor assembly fit, abnormal wear is further aggravated.
Customers are eager to find a forging supplier that can offer longer service life, higher impact resistance, and stable quality.
To address these pain points, Jianing Forging approaches both material selection and molding processes:
1. Use high-quality alloy structural steel, and by strictly controlling forging temperature and cooling rate, make the internal structure of the forging denser, achieving a good balance between hardness and toughness;
2. Introduces precision die forging technology to keep dimensional tolerances within ±0.5mm, helping to ensure a tight fit with the installation area;
3. Added surface strengthening treatment steps to enhance fatigue resistance and abrasive wear resistance, extending service life by more than 80% compared to the original plan.
After six consecutive months of testing in the mining area, no cracks or abnormal deformation occurred, and customers reported reduced maintenance frequency and a significant reduction in overall operating costs.
