Construction Machinery
Construction equipment (construction equipment) or heavy equipment (heavy equipment) is a machine used for construction. Construction machines are generally made strong and robust to handle large volumes of soil. In addition, various work machines are often operated by hydraulic devices. The development of powerful and easy-to-control hydraulic systems has contributed greatly to the emergence of these construction machines. Especially, high tension steel, special alloys and abrasion resistant alloys are used for the parts that are particularly impacted (excavation parts of buckets or blades) Is used. They made remarkable progress after the Second World War, and large-scale high-efficiency ones and high-mobility ones came into being one after another. As a result, the construction method has been changed, the construction period has been shortened, and the contents of the construction have dramatically improved.
