The maximum guaranteed load is 2.5 times the workload limit. The minimum ultimate strength is 4 times the working load limit Color paint or electroplating is available upon request Stainless steel AISI 316 Stainless steel 304 Electric galvanized steel
Single hook is simple to manufacture and easy to use, but it has poor stress conditions and is mostly used in work environments with a lifting capacity of less than 80 tons;
When lifting heavy loads, double hooks with symmetrical force are often used.
The laminated hook is made by riveting several steel plates that have been cut and formed.
When individual plates have cracks, the entire hook will not be damaged, and it has good safety. However, it has a large self weight and is mostly used in cranes for lifting heavy loads or lifting steel buckets.
The hook is often impacted during operation and must be made of high-quality carbon steel with good toughness.
The classification of hooks is extremely broad, generally including: shackles, lifting rings, circular rings, pear shaped rings, long lifting rings, combination lifting rings S-hook, nose hook, American style hook, sheep horn hook, eye shaped sliding hook, safety card hanging ring screw, chain shackle, with unique, novel, high-quality, and safe characteristics, suitable for factories, mines, petroleum, chemical, and ship docks, etc. Ensure safety, quality and safety factor, and achieve a static load of 3 times. The lifting capacity ranges from 5 tons to 150 tons.
