These machines have long been helping public utilities cope with icy roads and sidewalks. This communal equipment is designed to evenly spread the sand and salt mixture over the surface of the roadway and sidewalks.
The principle of operation and a brief description of the machine
This machine is most often produced in the form of a hinged module, which is mounted on the body of a truck, for which, on the latter, it is only necessary to remove the tailgate. Such attachments have a great advantage, since they do not require their own wheeled chassis - in the warm season, the truck can be used for its intended purpose.
The unit itself consists of a loading hopper, a conveyor and a spreader. The mixture is loaded into the hopper using a bucket loader or other loading equipment. However, some manufacturers offer models with their own boot device. During the operation of the machine, the mixture is conveyed along the conveyor to the spreading device, which has its own adjustments. It should be noted that the process of treating roads with reagents is a complex process, starting from the choice of the type of reagent and the proportion of mixing with sand, to the rate of consumption of the finished mixture, depending on the type of coverage and the category of the road. Using the spreader's adjustment device, the width of the cultivated area and the rate of mixture consumption can be adjusted, which makes it possible to use such a machine both on the carriageway of the motorway and on city sidewalks.
To power the working units of the sand spreader, only a connection to the electrical system of a car or a tractor is required, therefore it can even be installed on a trailer. This device is characterized by high efficiency and a fairly low price, as well as ease of maintenance, which makes it attractive for utilities of all forms of ownership.
Snow removal equipment is an integral part of the work of public utilities in the winter. The road treatment process has many critics who rely on the harmful properties of reagents, which can cause premature corrosion of car bodies, since most of these mixtures are made on the basis of salt. However, today there are many analogues that do not have such aggressive properties, so the treatment of the roadway and sidewalks with the help of a sand spreader will continue to be used in the future.
