Product Details

1. Double Brake Structure

The VD chain block features a double brake structure, ensuring precise locking and effective stall control. This design enhances safety by preventing unintended movement during lifting, providing users with peace of mind in critical operations.

2. Thickened Alloy Steel Cover

The reinforced triangular cover is made from thickened alloy steel, offering resistance to collisions and corrosion. This innovation significantly extends the product's service life, making it suitable for harsh industrial environments.

3. Streamlined Guide Wheel

Equipped with an enlarged guide sprocket and smooth bearings, the VD chain block minimizes resistance and ensures smooth chain operation. The integrated derailleur and gear cover further prevent chain jamming, enhancing reliability.

4. Three-Bearing Linkage Design

The three-bearing linkage design replaces traditional gear friction with rolling bearings, improving rotation efficiency and longevity. This advancement reduces maintenance needs and ensures consistent performance over time.

5. High-Strength Manganese Steel Pawl

The pawl is crafted from high-strength manganese steel, offering exceptional wear resistance and toughness. After quenching, the pawl becomes more durable, ensuring reliable operation even under heavy loads.

6. Safe-Designed Hook

The hook is quenched and refined with an anti-removal lock, making it robust and long-lasting. This design prevents accidental disengagement, further enhancing safety during lifting tasks.
