Crane is a very useful lifting device, which mainly relies on the hook in the lifting accessories to lift the heavy objects, and then through the mechanical operation of the crane to achieve the purpose of work.
However, we know that there is a very important relationship between the lifting hook and the weight, that is, the bearing capacity of the lifting hook must be lifted by the weight of the weight, which is also the use limit of lifting accessories.
Let's learn more about it together.
The maximum bearing capacity of lifting hook is called the danger point, which is the larger bearing capacity of lifting hook.
In most cases, in order to ensure the safe operation of hoisting machinery, the actual larger carrying capacity will be measured and measured before the hook is used.
The safety of crane is related to the life and property safety of staff when crane is operated, among which the ultimate bearing capacity of crane hook is a key index.
In order to ensure the safety and reliability of crane in operation, many countries have established relevant technical standards or laws and regulations to regulate the design, manufacture and use of crane hooks.
As time goes on, the strength safety of hoisting hook mainly relies on theoretical calculation and finite element numerical verification, and there is a lack of good evaluation method for the actual ultimate bearing capacity of the fixed production hook, especially the lifting hook with large rated load.
Therefore, it is difficult to determine the actual ultimate bearing capacity of such hooks and the safety factor of the relative rated lifting weight.
The bearing capacity of the hook is related to the performance of the equipment and the safety of the operator, so the performance index of the hook needs to be tested accordingly before normal construction.
