　　Crane hook is a large-scale lifting accessories that can be used in engineering factories. According to the different lifting range, they can be divided into large-tonnage lifting hooks and small-tonnage lifting hooks. So what are the characteristics of large-tonnage lifting hooks? Next, let’s take a look at the manufacturer’s introduction:

　　1. The lifting hook is one of the important lifting components in lifting machinery. Its materials are generally made of 20 steel or 16mn steel.

　　2. Most hooks use M and P strength grades to ensure good rigidity and hardness.

　　3. A single-hook structure form of a mold calcined threaded handle with lugs.

　　4. The cross-section of the hook body (mostly) is rounded trapezoidal, and the inner side is a large edge. This can increase the area under pressure of the ring or rope, so that the strengths inside and outside the cross-section are close to equal, which not only makes rational use of materials, but also reduces the weight of the hook.

　　5. The material of the lifting hook is made of antimagnetic steel, and is solid-melted after mold calcination. The hardness is up to 180HB, and it has high mechanical strength and impact toughness. In addition to being able to withstand the weight of the hanging object, it can also withstand the large impact load when the lifting mechanism is started and braking.
