Mining trucks operate for long periods under heavy loads, high wear, and complex road conditions, making the wheels prone to cracking, deformation, and early fatigue, leading to frequent repairs and delays. Mining wheel forgings made with high-quality alloy steel forging processes are optimized for mining conditions from materials to forming processes, improving wheel impact resistance and service life, and reducing downtime losses.

Mining wheel forgings made with high-quality alloy steel forging processes are optimized for mining conditions from materials to forming processes, improving wheel impact resistance and service life, and reducing downtime losses.
This product is a mining wheel forging produced by Jianing Forging, selected from relatively high-strength alloy steels (such as 40Cr, 42CrMo, etc.). Through die forging and fine heat treatment, it achieves a fine grain structure and uniform hardness distribution. Products are strictly manufactured according to customer drawings or industry standards (such as GB/T 12361, JB/T 9177), suitable for various types of mining dump trucks, underground transport vehicles, rail mining cars, and other heavy vehicles.
Relatively high strength and toughness: Selected alloy steel, dense after die forging, balancing tensile strength and impact toughness, suitable for heavy-duty impacts.
Long wear resistance and lifespan: Using controlled forging ratio and heat treatment quenching and tempering processes, the wheel flange and tread hardness are uniform, with wear resistance superior to castings.
High dimensional accuracy: mold processing works in conjunction with subsequent cold processing, with key dimensional tolerances controlled within ±0.5mm, making installation convenient.
Fatigue reliability: Few internal defects, using ultrasonic and magnetic particle flaw detection to meet frequent mine start-stop and heavy load requirements.
Customizable adaptation: supports modification of structure, materials, and surface treatments (such as bluishing, galvanizing, quenching) according to customer drawings.
This product is custom-made on demand, with prices determined based on material specifications, purchase quantity, and processing requirements. Please provide specific drawings, operating conditions, and expected load requirements, and we will provide a targeted quotation plan.
We offer pre-sales technical selection assistance, transparent tracking of production progress, and pre-shipment inspection reports for each piece (including material lists and flaw detection records). If non-human manufacturing defects are found after delivery, unconditional replacement or repair within 30 days; We can also provide value-added services such as spare stock inventory and regular follow-up visits for long-term partners.
