Chongming Engineering Forklift Wheel Forging Case, Shanghai

Case Overview

Jianing Forging collaborated with a major construction machinery manufacturer in Chongming, Shanghai, to supply custom forged forklift wheels. These wheels are critical components for heavy-duty forklifts used in port logistics and warehouse operations. The project required high strength, durability, and precise dimensional accuracy to withstand continuous loading and harsh operating environments.

Customer Challenges

The client faced frequent wheel failures due to cracking and deformation under heavy loads. Existing cast wheels had inconsistent grain structure, leading to premature wear and safety risks. Additionally, long lead times and high scrap rates from conventional forging methods increased operational costs. The client needed a reliable solution that could deliver consistent quality, reduce downtime, and improve overall equipment lifespan.

Solution & Product Advantages

Jianing Forging developed a closed-die hot forging process specifically for the forklift wheel application. The solution focused on three key areas: material selection, forging design, and post-treatment. Using a high-strength alloy steel (45# steel with optimized carbon content), we achieved a refined grain structure and improved impact resistance. The forging process eliminated internal voids and ensured uniform density across the wheel rim and hub. After forging, each wheel underwent controlled cooling and shot blasting to enhance surface hardness and fatigue life. The final product met strict dimensional tolerances (within ±0.5 mm) and passed 100% ultrasonic testing. As a result, the client reported a 40% reduction in wheel replacement frequency and a 25% increase in forklift uptime.
