Any engineering equipment has its own role. In the long process of development, the role of mechanical equipment has become more and more enriched, and even can be said to be indispensable. So, in the first manual era, how were these devices developed? In what context was the straightening machine generated?
For the straightening machine, it is the maintenance machine for building steel pipe scaffolding. At the beginning, there was no such equipment. Later, the scale of construction in China expanded year by year, and bamboo scaffolding was quickly replaced by building steel pipes. However, after a long period of sun and rain, the steel pipe will be rusted and corroded, the pipe wall will become thinner, and it will be easily bent during construction disassembly and handling, which will reduce the service life and cause a series of safety hazards.
After that, many construction companies spent a lot of manpower and resources on the maintenance of steel pipes, but the results were not satisfactory. In this context, the straightening machine began to slowly emerge. Later, after continuous development, its role became more and more obvious, and it became one of the indispensable mechanical equipment on the construction site.
