Our BL series heavy-duty leaf chains cover mainstream models BL622, BL623, BL646 and BL866, professionally manufactured with high-quality carbon steel as the core material. Complying with international industrial standards, this series of lifting chains features high tensile strength, low elongation and excellent load-bearing performance. It is specially developed for forklift lifting systems, hoist equipment, warehouse stackers and industrial vertical lifting machinery, serving as the core tension and lifting transmission component. Reliable and durable, it is the ideal replacement and original matching part for industrial heavy-load lifting equipment.
Core Product Advantages
1. Premium Carbon Steel Material, Super Load Capacity
Made of high-quality industrial carbon steel, the leaf chain adopts multi-layer plate stacked structure and integral riveting forming. With overall quenching and tempering heat treatment, the product boasts high structural hardness and strong tensile resistance. It stably bears heavy lifting loads without deformation, stretching or fracture, fully adapting to long-term high-frequency heavy-load operation of forklifts and hoist equipment.
2. Low Elongation & Anti-Fatigue, Stable Lifting
Precision industrial manufacturing effectively reduces chain elongation under tension. The chain maintains stable length and structural tightness during frequent lifting and reciprocating movement, avoiding equipment jitter, positioning deviation and safety hazards caused by chain deformation. Excellent anti-fatigue performance ensures long-term continuous stable operation, greatly improving equipment working safety and efficiency.
3. Precision Machining & Perfect Matching
All chain plates, pins and rivets are processed by high-precision CNC technology with strict dimensional tolerance control. The chain runs flexibly and smoothly without jamming or abnormal noise. Standard specification design ensures perfect compatibility with mainstream forklifts, hoists and warehouse lifting equipment, realizing accurate assembly and stable transmission.
4. Wear & Corrosion Resistance, Long Service Life
Key components undergo surface strengthening and professional anti-rust treatment. The chain features outstanding wear resistance, dust resistance and oxidation resistance, adapting to complex working environments such as factory workshops, warehouses and outdoor freight yards. It resists daily friction and environmental erosion, reducing replacement frequency and lowering equipment operation and maintenance costs.
5. Complete Specifications & Wide Applicability
Complete BL series models including BL622, BL623, BL646, BL866 are available to meet different load-level lifting demands. The series covers light, medium and heavy load specifications, widely applicable to various brand forklifts, lifting hoists, stackers and material handling equipment, supporting standard replacement and customized matching.
