Common hook types and material characteristics
The commonly used hook forms of the trolley can be divided into forged hooks and plate hooks. The forged hooks are divided into single hooks and double hooks; single hooks are used for trolleys below 80T; double hooks are used for trolleys above 80T. The board hooks are made of multiple steel plates cut into hook-shaped and pressed. They are equipped with pads at the hook mouth, which can not only reduce wear on the hook body, but also allow the load to be distributed on each hook piece. It is mainly used on large lifting vans and metallurgical vans.
The hook is one of the important stress-bearing components of the van. It not only bears the weight of the hanging object, but also bears the impact load generated by the hanging object during the mechanism starting and braking. Therefore, the material of the hook is required to have high mechanical strength, but also has good toughness. The materials for forged hooks are often made of 20 and 20 SiMn steel, while plate hooks are often made of Q235 and 16Mn steel. Therefore, we need to choose different hooks according to the type of hook. Only by choosing products according to needs can we ensure the operation safety of large cranes.
