The VD chain block represents a significant advancement in manual lifting technology, combining lightweight design with robust performance. Manufactured by Qingyuan Juli Hoisting Machinery Co., Ltd., this product is engineered to meet the demands of diverse industrial environments. Its compact structure, enhanced durability, and improved efficiency make it a preferred choice for tasks ranging from equipment installation to cargo handling.
The VD chain block is designed with double brake structure, ensuring precise locking positions and effective stall control. This feature enhances safety by preventing unexpected movement during lifting operations. The thickened alloy steel cover provides resistance to collisions and corrosion, significantly extending the product's service life. Additionally, the streamlined guide wheel with a smooth bearing system minimizes resistance, ensuring smooth chain movement and reducing the risk of jamming.
The three-bearing linkage design replaces traditional gear friction with rolling bearings, improving rotation efficiency and longevity. The high-strength manganese steel pawl, after quenching, offers exceptional toughness and wear resistance. The safe-designed hook is quenched and features an anti-removal lock, ensuring durability and user safety.
