Crane repair three methods to repair jib cranes
The jib crane is constructed from many parts. And these parts are damaged due to various elements in the process of use. If these parts are discarded in this way, we will feel very bad.
Standard method for crane repair and repair: The shafts and holes of jib crane parts are formed into elliptical and irregular rectangular shapes due to uneven wear during use. When revising, within the planning allowed by the part structure, the worn shafts or holes are machined, so that they can be modified to restore the correct geometry or cooperative properties. This method is called the repair standard method.
Crane repair inserting method: inserting inserts is to insert new metal sleeves on the worn parts of the parts by static cooperation to restore the parts to the original specifications. This method is called inserting inserts.
Crane repair part replacement, turning and overturning repair method: When the damage occurs on the part of the part, the other parts of the boom crane method do not need to be repaired, remove the part that needs to be repaired, and then use welding to connect to the main body of the part. , The correction method of the original function of the final processed rehabilitation part is called partial replacement. Some parts tend to wear unilaterally because of the characteristics used, and the symmetrical side wears less. If the structure of the part permits, sharing the three types of correction screws can use the unworn side of the part without thoroughly repairing the part. This is called the turning and overturning repair method.
