Bearing capacity of crane lifting hook
Nov 16, 2018

The crane is a very widely used lifting device. Its work mainly relies on the hooks in the lifting parts to lift the heavy objects, and then through the mechanical operation of the crane to achieve the purpose of work. It is only we know that there is a very important relationship between the hook and the heavy object, that is, the weight of the hook must be carried out to lift the weight of the heavy object, which is also the use limit of the lifting accessory hook. Let's take a closer look at it.


The large bearing capacity of the lifting hook during operation is called a dangerous point, which is the larger bearing capacity of the hook.


In most cases, in order to ensure the safe operation of the lifting device, the actual large bearing capacity is measured and measured before the hook is used. The following is a description of the bearing capacity of the lifting hook.


When the crane is in operation, its safety is related to the safety of the workers and the property. The bearing capacity of the crane hook is a key indicator.


In order to ensure the safety and reliability of the crane during operation, many countries have developed relevant technical standards or regulations for hooks to regulate the design, manufacture and use of hooks.


With the passage of time, the strength safety problem of the lifting hook mainly relies on theoretical calculation and finite element numerical check. The actual bearing capacity of the hooks that have been shaped, especially the hooks with large lifting weight, is not very good. Assessment method.


Therefore, the current bearing capacity of such hooks and the safety factor of relative rated lifting weight are difficult to determine.


The bearing capacity of the hook is related to the performance of the equipment and the safety of the operator, so the performance index needs to be tested to normal construction.
