The pulley diameter ranges from 300mm to 1524mm with multiple specifications available, which can precisely match different models of drilling winches and traveling block hooks. The pulley adopts a forged-welded structure, with the hub and rim made of high-strength alloy steel, equipped with high-precision bearings. It has a compact structure and uniform force distribution, which can effectively reduce rope wear, improve transmission efficiency, and is suitable for long-term high-load operations. Special size customization is supported.
The finished products undergo wet fluorescent powder inspection to eliminate defects such as cracks and porosity, ensuring the product's load-bearing capacity meets the standard. Equipped with dust-proof oil seals, it effectively prevents sand, mud, and oil from entering the bearings, reducing maintenance frequency and cost, and ensuring long-term stable operation of the equipment.
