Every year, utilities are faced with the need to clear snow debris and ice on the roads. The principle of their work is quite simple. The reagent is poured into the bunker and fed through a belt or screw elevator to the metering unit. Then it hits the rotating disk and is scattered to the desired distance. A sand-salt mixture is used as a reagent. And let the cost of its small, however, consumption is undesirable, so before work it is recommended to clear the road from the snow.
Trailed can be of several varieties. Small models weighing up to 800 kg are used with light vehicles such as Gazelle or UAZ. Larger models are used with trucks and snow removal equipment based on them. All types of sand spreaders can be grouped into several types:
Mounted applicable in combination with tracked tractors and wheel type, as well as utility and snow machines. They have a small bunker, so they are used in small areas, or with partial icing. They are powered by using the tractor's power take-off shaft or the vehicle's hydraulic system.
For large areas, the use of body sand spreaders is suitable. They are equipped with fairly large bunkers and are able to turn a simple one functional machine into a real special equipment for handling snowy roads. They must be firmly fixed on board the car and use the hydraulic system for power. In addition, often these models are equipped with a remote control panel, so that the operator can work without leaving the cab.
In view of the widespread use of MTZ tractors on the territory of Russia, production of MTZ 82 sandbars has been established. They are characterized by simple conditions of use and low cost. However, the use of low-quality materials in the manufacture contribute to rapid wear due to metal corrosion. So, they are subject to frequent replacement. Backgammon with such models demand complex road machines such as KAMAZ. However, it should be borne in mind that with equal configuration, the use of low- quality components in order to reduce the cost of the finished product leads to a deterioration in performance.
The cost of sanding equipment is formed by the following indicators:
- bunker capacity
- Manufacturing material
- Type of drive
