A salt spreader is a machine used to distribute salt or other materials evenly over surfaces, primarily for de-icing roads and sidewalks during winter. It helps prevent ice formation, making travel safer for vehicles and pedestrians. Salt spreaders can be mounted on vehicles or operated manually, depending on the size of the area to be treated. These devices come in various types, including broadcast spreaders and drop spreaders. Broadcast spreaders fling salt over a wide area, while drop spreaders release it directly below the machine. Both types are essential tools for municipalities and homeowners to manage winter weather effectively.
