In the modern world, there is a huge amount of special-purpose equipment used in various fields. Special equipment includes graders - machines that are usually used on construction sites, forestry and agriculture. Also, these special vehicles can be found on city streets, for example, while removing snow from the streets.

What is a grader

Grader is a self-propelled vehicle or trailed mechanism, the main purpose of which is leveling the surface, cleaning ditches and construction sites, paving, soil distribution, and slope profiling. These machines are most in demand in the autumn-winter season, when it becomes necessary to clean city streets from dirt, leaves or snow.

The question of what a grader is can be answered in a simpler language - it is a special tool that has multiple similarities with a tractor, but unlike the latter, it is equipped with a unique mechanism, which is a blade with a knife,frame mounted.

The blade can not only lower or rise, but also turn both horizontally and vertically. Such characteristics of the grader make this special equipment universal, allowing it to be used in various types of work.

Classification

Now we know what a grader is and how it is used. By the way, for more effective use in a particular area, machines are created, the dimensions and technical characteristics of which have significant differences. Grader classification is as follows:

• light (engine capacity up to 75 hp);
• medium (engine capacity up to 100 hp);
• heavy (engine size up to 180 hp);
• super heavy (engine size over 400 hp).

As a rule, models with an engine capacity of up to 100 liters. with., are used by public utilities for cleaning streets, as well as for leveling the soil, for example, after repairing heating mains.

Medium-weight graders are most often used in the construction of unpaved roads and in the performance of repair and road works in the city. Heavy and extra-heavy machines are used for spreading soil that has a high density. With impressive technical characteristics, such a grader can easily cope with soil of any density.

Mechanical and hydraulic

Knowing what graders are, it is necessary to be able to distinguish them by the way they function. Similar Informationwill help you choose the most effective type of equipment and complete the work as soon as possible. All graders are divided into:

• hydraulic;
• mechanical.

As a rule, hydraulic graders are used on small sites, as these machines are more maneuverable, smoother in operation, and also do not require high professional skills from the driver-operator. More difficult to manage are special equipment with a mechanical manual drive.

Conclusion

Graders are special equipment with wide functionality. Such a machine will become an indispensable assistant in agriculture, construction, and even on the streets of small and large cities.
