Overhead Cranes Inspection Peculiarities & Real Use Cases

To date, the issues of safe operation and examination of industrial safety of lifting equipment is absolutely vital since it falls in the focus of many supervisory authorities. One of the components of the examination of lifting devices is a significant technical diagnosis of overhead cranes to identify hazardous operational defects. In this article, prepared in close collaboration with GMH Company, Granada Material Handling, specialised in overhead cranes and gantry hoist production and maintenance and being one of the UK industry leaders, we consider the experience of the application of acoustic emission control method for diagnosing metalwork lifting structures.

From the experience of operating gantry cranes it is known that the a result of the impact of various adverse factors forms dangerous fatigue failures. The identification of such defects in the course of the examination of cranes traditional methods of control over existing methods is extremely problematic, especially in remote or hard to reach areas. On this basis, to identify hazardous operational defects and reliable assessment of the technical condition of the crane, the companies may want to make use of the acoustic emission method. This method makes it possible to record wave elastic stresses arising from internal local dynamic restructuring of the material structure. These processes are accompanied by the accumulation of structural damage, the formation and growth of cracks that eventually lead to a limiting conditions and structural failures. Read more »
