ANSI Standard AL Series Leaf Chain Manufacturer | Precision Light/Medium Duty Lifting
Reliable counterweight balancing and vertical material lifting require precision-engineered tension chains. JINQIU CHAIN, a leading AL series leaf chain manufacturer and global supplier, provides complete, high-capacity supply chain services for foreign OEMs, large industrial distributors, dealers, and terminal machinery plants worldwide. Manufactured in our 60,000㎡ ISO-certified facility, our AL leaf chains fully conform to ANSI B29.8 standard specifications, offering seamless interchangeable lifting solutions for light-to-medium industrial equipment.
Engineering Excellence for Smooth & Dynamic Counterbalance Lifting
ANSI Standard Component Synergy: Engineered using link plates and pins derived from ANSI standard pitch dimensions, ensuring exact dimensional compatibility and flawless fitment with OEM clevises.
In-House Heat Treatment: All alloy steel pins undergo advanced continuous carbonitriding and high-frequency surface hardening, delivering high core toughness and exceptional fatigue resistance under dynamic loads.
100-Ton Tensile Verification: Every batch of JINQIU AL leaf chains undergoes strict factory pre-stretching and destructive tensile testing up to 100 tons to guarantee high ultimate breaking strength and zero operational elongation.
50+ Professional Engineers: Our technical team offers rapid CAD design support, custom lacing combinations (e.g., AL422, AL544, AL666), and specialized clevis configurations for non-standard machinery.
Optimized for Light Forklifts, Machine Tool Counterweights & Hydraulic Lifts
Eliminating machine downtime and ensuring operator safety are critical for material handling equipment. JINQIU’s AL series leaf chains feature high-precision blanked link plates and hot-dip synthetic pre-lubrication to resist joint wear and dynamic fatigue. Partnering directly with China's top chain source provides global distributors and OEMs with competitive factory-direct pricing, stable volume production, and complete OEM/ODM custom manufacturing services.
