The main girder structure of overhead travelling crane will be deformed by various factors in the process of long-term application, and the deformation problem can not be completely avoided, for the deformation of the main girder structure.

Excavator bucket rod upper end cracking reason analysis and improvement,1.Cracking phenomenon of a model of excavator factory work 3000h or so, one after another, the upper end of the bucket rod cracking phenomenon, cracking part is located in the top of the bucket rod reinforcing plate and the bucket rod cylinder piston rod support plate articulation overlap weld at the vertical plate.

Manufacturing is the foundation of national strength, please pay attention to “metal processing” (mw1950pub).

Welding deformation control methods are diverse and can be applied flexibly in different situations. Due to the complexity of the welding process and the ever-changing morphology of steel structures, the search for efficient control methods has always been the focus of research in the field of structural steel welding.

Vibrating screen side plate cracking is not to be afraid of, a few simple steps can be easily fixed! (With specific processing steps) Vibrating screen is easy to appear after a long period of operation, such as cross beams, track beams and other fracture and side plate cracks and other problems, cross beams and track beams can be solved by replacing, and the side plate out of the
