Road milling machine – this is a special car, which is used to destroy and remove the top layer of asphalt or concrete from the road surface. It consists of two main parts: working body and chassis.
- Working body – it is a rotating drum with cutting teeth, which cut the road surface under the influence of gravity and hydraulic drive. Cutting teeth can be made of steel, tungsten carbide or polycrystalline diamond. Cutting teeth are subject to wear and require periodic replacement.
- Chassis – this is the frame of the car, on which the working element is installed, engine, fuel tank, hydraulic system, operator cabin and other elements. The chassis can be wheeled or tracked depending on the type of road milling machine and working conditions. Wheel cutters are more mobile and maneuverable, but less stable on uneven surfaces. Crawler cutters are more stable and passable, but less fast and flexible.
The operating principle of the road milling machine is as follows: the operator controls the machine using the steering wheel, pedals and joystick. He chooses the speed of movement, milling depth and width, drum rotation direction and angle. The operator also controls the operation of the cooling system, cleaning and lubrication of the working body.
When the road milling machine starts moving, the drum is lowered onto the road surface and begins to rotate. Cutting teeth cut off the top layer of asphalt or concrete and lift it up in the form of chips or shavings. Chips or shavings are thrown onto the conveyor belt, which carries her to the back of the car. There, wood chips or shavings are dumped into a dump truck or other vehicle for further processing or disposal..
The road milling machine can work in a straight line, and along the curve. To do this, the operator can change the angle of rotation of the drum relative to the chassis. The operator can also adjust the depth and width of milling depending on the requirements for quality and productivity.
To control the road milling machine volgograd.prava112.com/dorozhnaya-freza, you need to have rights. The machine is used for various purposes, such as:
- Road repair and reconstruction, bridges, airfields and other transport infrastructure facilities.
- Removing defects, cracks, potholes, potholes and other damage to the road surface.
- Reducing road height to improve drainage, snow retention and traffic safety.
- Preparing the surface for applying a new layer of asphalt or concrete.
- Creating special designs, patterns, inscriptions and other design elements on the road surface.
Road milling machine – this is an effective and environmentally friendly way to renew and improve road surfaces. It allows you to reduce material costs, fuel and labor, and also reduce emissions of harmful substances into the atmosphere.
