A grader is an important mechanical equipment used in projects such as land leveling and road construction. The following are five common basic types of graders:
Towed grader is one of the earliest types. It needs to be towed by a tractor or other traction equipment to work. This type of grader has a relatively simple structure and low cost. Its working device mainly includes a scraper, etc. When working, it moves by the power of the traction equipment, and the scraper scrapes and levels the ground. It is suitable for some small-scale site leveling projects that do not require extremely high flatness, such as the preliminary leveling of small farmland or the pretreatment of some simple construction sites.
Self-propelled grader is a type widely used in modern engineering. It is equipped with an engine and a walking device, and can travel and operate independently. Self-propelled graders have high maneuverability and operating efficiency. Its scraper can be adjusted at various angles, including left and right tilting, up and down lifting, and rotation. It can accurately control the height and slope of the flat ground, and is widely used in large-scale projects such as highway construction and airport runway construction, and has strict requirements on the flatness of the ground.
The hydraulic drive grader is developed on the basis of the self-propelled grader. It uses a hydraulic system to drive the movement of key working parts such as the scraper. Compared with the traditional mechanical transmission method, the hydraulic drive is smoother and more precise. It can achieve more delicate operations, such as more precise control when adjusting the angle and force of the scraper. This grader performs well in the fine leveling of high-grade highways and some special site construction with extremely small flatness errors.
The body of the articulated grader is connected by a hinge point. This unique structural design makes the grader more flexible when turning and can work better in narrow construction sites or complex terrain conditions. It can reduce the turning radius and improve the passability and adaptability of the equipment. It has unique advantages in projects with special terrain restrictions such as mountain road construction and urban road reconstruction.
In addition to the basic leveling function, multifunctional graders can also be equipped with a variety of auxiliary devices. For example, some can be equipped with a tiller to loosen the hard soil before leveling the land; some can be equipped with a bulldozer, which has both bulldozing and leveling functions. This type of grader improves the utilization rate of the equipment, can adapt to more diverse construction needs, and plays an important role in comprehensive engineering construction projects.
