How to make a hook
Hook is the most widely used picking device on cranes. In hoisting operations, the hook and pulley are combined together, which is also a commonly used picking device. The types of hooks are divided into two types according to their manufacturing method: forged hooks and plate hooks (commonly known as plate hooks). You need a 25-ton hook for cranes. There are this specification. It has different series such as car cranes and bridge cranes. There are many domestic manufacturers. Products from Dalian, Jiangsu and Hebei are more popular, and some Henan products have poor quality and lower prices. There is a lot of information online.
The hooks are divided into single hooks and double hooks according to their shape; they are divided into cast hooks and stacked hooks according to the production method.
Single hooks are simple to make and easy to use, but their stress conditions are not good, and they are mostly used in operation places where the lifting weight is less than 80 tons; double hooks with symmetrical stress are often used. The stacked hook is made of several cut steel plates. The entire hook will not be damaged when a single plate has cracks. It has good safety, but its own weight is large. It is mostly used on cranes that lift large lifting weights or lift steel buckets. The hook is often impacted during the operation process and must be made of high-quality carbon steel with good resistance.
The hook can be divided into cast hooks and sheet hooks according to the production method.
Casted hooks can be divided into single hooks and double hooks.
Single hooks are generally used for small lifting weights, and double hooks are mostly used for larger lifting weights. Plate hooks are also divided into single hooks and double hooks.
Single hook: It is a relatively commonly used hook with a simple structure and convenient application. The information is generally made of 20# high-quality carbon steel or 20Mn, and the maximum lifting capacity is no more than 80 tons.
Double hooks: When lifting weight is large, double hooks are often used, and the force is uniform and symmetrical. The data are generally made of 20# high-quality carbon steel or 20Mn, and are usually made of lifting equipment larger than 80 tons.
The hook for lifting tissue driven by humans is used to conduct experiments with 1.5 times the additional load as the inspection load. The hook for the lifting tissue driven by power is used to conduct experiments with 2 times the additional load as the inspection load. After the hook is removed from the check load, there should not be any significant disadvantages or deformations, and the increase in opening degree should not exceed 0.25% of the original scale. For hooks that pass the inspection, symbols should be printed in the low-stress area of the hook, including additional lifting weight, factory mark or factory name, inspection symbols, production numbers, etc.
The hooks are of very wide classification, usually including: shackles, rings, rings, pear-shaped rings, long rings, combined rings, S-hooks, nose hooks, American hooks, sheep horn hooks, eye-shaped sliding hooks, secure clamping ring screws, chain shackles, common, novel, high-quality and safe characteristics, suitable for factories and mines, petroleum, chemical and ship terminal number.
The above is the complete introduction of the hook. Are you still satisfied with it!
