Swivel crane hooks are forged from high-strength alloy steel, designed for swivel hook heavy duty lifting. With 360° smooth rotation, they prevent rope twisting and improve safety. Precision bearings ensure stability, while heat treatment and anti-corrosion coating extend service life. Certified and tested at 1.5× load, they cover wide crane hook capacity, making them reliable for ports, construction, mining, and steel plants.
