Heavy Duty BL Series Leaf Chain BL622 BL623 BL646 BL866 Carbon Steel Forklift Lifting Hoist Chain
Product Description

Premium Carbon Steel Construction: Made of high-quality carbon steel (40Mn or equivalent alloy steel) for superior hardness, wear resistance, and load-bearing capacity, ensuring long-term service life even under heavy loads and frequent use.
Heavy-Duty Performance: Specifically designed for heavy lifting and transmission tasks, with high fatigue strength and impact resistance to withstand the stress of forklift lifting, hoisting operations, and continuous conveyor movement.
Precision Manufacturing: Adopts advanced production processes including ball-burnished plate holes to minimize friction, enhance fatigue resistance, and ensure smooth operation, reducing maintenance costs and downtime.
Versatile Application: Suitable for a wide range of industrial scenarios, including forklift truck lifting mechanisms, hoisting equipment, conveyor systems, mining machinery, agricultural machinery, and packaging equipment.
Customization Available: We offer customized solutions (size, surface treatment, packaging) to meet specific customer requirements, supporting OEM/ODM services for global partners.
Corrosion Resistance Option: Optional surface treatments such as Dacromet-plating or oil blooming are available to enhance corrosion resistance, suitable for harsh working environments like marine, food processing, and outdoor applications.
