Graders

There are different types of graders. They are widely used in road construction. They can excavate ditches, shape the surfaces and sides of fills, etc. More manoeuvrable grader is a power grader. It consists of a blade and a scarifier. The grader can be used when required with all kinds of changeable pendant equipment such as conveyors, snow ploughs, etc. There are light hydraulically controlled power graders. They have a 65-horse power engine. But medium-power graders have a 100-horse power engine.

Now a new and a powerful grader is being produced. It is powered by a diesel engine. Power is transmitted through a constant mesh transmission to the four wheel tandem drive. The driving axle which is centered between the wheels allows each of the four wheels to easily follow ground irregularities (неровности) and pass over obstructions. This grader has the usual standard features: leaning (наклонный) front wheel which is hydraulically operated and manual steering (ручное управление) with hydraulic boost (усилитель).
