Truck Grit Spreader

A truck grit spreader is often called just a gritter and is used by local councils to spread the grit on large areas of road and some public car parks when there is ice and snow on the ground. Some business owners will use a truck grit spreader if they have large company grounds and a company car park or if it is a company that runs private car parks. Ice and snow make for dangerous conditions when you are walking and even more dangerous when you are driving.

Grit is spread over major roads, car parks and business grounds to prevent people from slipping on the ice and having a fall that could result in a broken bone. Gritted roads are safer for drivers because the grit creates more friction between the tyres and the road surface, which gives the wheels greater grip on the ice. Grit is also mixed with rock salt and it is the salt that makes it safer for pedestrians to walk in bad weather because it lowers the point at which ice freezes by acting like antifreeze does in a car. Salt is only efficient at making the ice liquid when the temperature is above minus five degrees centigrade, when the temperature drops below this, the salt will not work until the temperature of the ground underneath is raised.

What is a Truck Grit Spreader?

A truck grit spreader is actually a large hopper or grit bin that fits on the back of a truck. Usually the truck grit spreader will have a mesh guard over the top to prevent objects getting into the grit and spoiling not only the performance of the grit, but jamming up the mechanism as well. A truck grit spreader has a spreading mechanism that contains a tube or impeller that sprinkles the salt in a continuous flow onto the surface of the ice and snow. The grit spreader works by means of a generator that is driven by an electric motor and a combustion engine, this forms the motor or hydraulic drive system which is attached to a small onboard motor and to which the impeller is attacked and which causes the truck grit spreader mechanism to work.

The amount of salt that is dropped by a truck grit spreader depends on the condition of the road judged by the amount of snow and ice that needs to be removed. The salt is dropped independently of the grit or sand, which is why the volume of salt that is spread can be varied. Sometimes the grit is passed through the nozzle and heated at the same time and this helps to speed up the solubility of the salt and the rate at which it works. In the past, the truck grit spreader was not so automated and men with shovels would be stood in the back of the truck shovelling out the grit as the truck moved along.
