Analysis of the causes of deformation of various metal structures of bridge cranes

Friends who have seen bridge cranes should know that it is a large and heavy production equipment. Therefore, in actual use, due to various factors, the equipment may have many emergencies. The structural deformation of the crane is a common one. The kind of existence. The work we have to do is to analyze the causes of deformation and how to eliminate it.

Many parts of the bridge crane are made of metal structures, so these parts are prone to deformation, and different positions cause different causes of deformation. for example

1. Deformation of the main beam

The main girder of the crane has obvious deformation and is easy to be found, so its upper arch will be reduced. The reason for this phenomenon is nothing more than the internal stress of the structure; the overload of the machine and the influence of the working environment; the unreasonable operation technology and so on.

2. Web deformation

The web is a component of the main beam and is generally obtained by splicing. Therefore, the effect of welding internal stress and the flatness of the steel plate itself are not in compliance with the requirements, etc., which are the reasons for its deformation.

In view of the above deformation, there are many ways to eliminate it. The more commonly used and effective methods are prestressed steel bar tension, prestressed steel wire rope tension, flame correction method, etc. The safe operation of the crane can be ensured after the deformation is eliminated.
