The VD series features an upgraded compact structure, a double brake system for enhanced safety, and a three-bearing linkage design that reduces friction and increases lifting efficiency compared to standard models.
Safety is ensured through a double brake structure for precise locking, quenched manganese steel pawls for fracture resistance, and hooks equipped with anti-removal locks.
Yes, while the standard lifting height ranges from 2.5m to 3m, extra lifting height is available. Please refer to the "Extra weight per meter" parameters for specific model weight increases.
The VD chain block utilizes a thickened alloy steel cover with a reinforced triangular design, specifically engineered to be anti-collision and anti-corrosion for long-term industrial use.
It employs an enlarged guide sprocket with smooth bearings and a dedicated derailleur and gear cover that fit the chain perfectly, resulting in zero resistance and zero jamming.
For a 15-ton load, we recommend the VD-20 model, which has a rated capacity of 20t and a test load capacity of 25t, providing a safe margin for your operations.
