Modern State and Development of Grader Blades for Earth Moving and Snow Removal

The article discusses the modern state and development of grader blades for earth moving and snow removal. The grader blades of road machinery are made of different materials depending on the conditions in which they will be used. Modern polyurethane designs are not inferior to their performance characteristics of metal. New designs are being actively developed, and the existing designs of grader blades for snow plough are being improved to improve energy saving and cleaning efficiency of road surfaces from loose snow, packed snow and ice formations, as well as to ensure the safety of pavement and structures and to prevent damage to the blade and equipment of the base machine. The trends of a new principle of influence on the developed environment with the help of high-impulse vibrations are traced with the purpose of increasing the efficiency of snow-removal equipment. In the structures of the work tool of road construction machinery, disc cutters are used to improve the efficiency of soil destruction and snow–ice formations. The developed design of grader blades of a snow-removing machinery with installed disc cutters is presented. The proposed technical solution allows one to significantly increase the energy efficiency of the snow-removal process without increasing the power of the base machine.
