Road Milling Machine Concrete Scarifier

【Product Introduction】

Road milling machine or concrete scarifier is a road repair equipment. It is based on the principle of mechanical cutting and uses high-speed rotating milling cutters to cut the concrete floor. Road milling machine or concrete scarifier can be widely used in planing, cutting and leveling operations of the road surface.

【Product Features】

Powerful Power
The road milling machine concrete scarifier is equipped with a 9kW high-performance motor, which is powerful enough to easily handle high-strength working surfaces such as hard concrete floors, old epoxy layers, and workshop oily layers. It can maintain stable output even under continuous construction or heavy loads.

Adjustable Planing Depth
The road milling machine concrete scarifier supports 3-10mm continuously adjustable depth to meet different construction needs, from light surface treatment to deep planing.

Wear-resistant Tool
The road milling machine concrete scarifier uses a high-strength alloy steel tool head, which has a 30% increase in wear resistance. The average service life of each set of tools can reach 80-100 hours.

【Frequently Asked Questions】

Q: What is the working principle of road milling machine concrete scarifier?
The road milling machine concrete scarifier drives the milling drum to rotate at high speed through the engine, and the cutter on the milling drum cuts the concrete surface. During the rotation process, the cutter moves relative to the ground, removing the concrete layer by layer, thereby achieving the purpose of changing the flatness of the ground or removing the old coating.

Q: How does the road milling machine concrete scarifier control the milling depth?
The road milling machine concrete scarifier controls the milling depth through the depth adjustment device set on the fuselage. Generally, there are two ways of mechanical adjustment and electronic adjustment. Mechanical adjustment relies on components such as screws to change the height position of the milling drum; electronic adjustment uses sensors to measure the actual depth and compare it with the preset depth, automatically adjusting the milling drum to rise and fall, so as to accurately reach the required milling depth and keep it constant.

Q: What are the main structural components of the road milling machine concrete scarifier?
The road milling machine concrete scarifier is mainly composed of an engine, a frame, a milling drum, a cutter, a walking system, a hydraulic system, a control system, and other parts. The engine provides power, the frame carries various components, the milling drum and cutter perform milling tasks, the walking system ensures the movement of the equipment, the hydraulic system drives the various moving parts, and the control system coordinates the operation of various parts.

Q: What scenarios are road milling machine concrete scarifier suitable for?

Road milling machine concrete scarifier is suitable for the renovation of old concrete pavement, removing the wear layer and disease layer of the pavement, and restoring the flatness of the pavement; when the road is widened, the edge concrete can be milled; it is also used for the maintenance and renovation of airport runways and bridge deck concrete, removing the surface anti-skid wear or making new anti-skid patterns, and can also deal with concrete pavement misalignment, congestion and other diseases.

Q: What role does road milling machine concrete scarifier play in the construction of large parking lots?

In the construction of large parking lots, road milling machine concrete scarifier can level and mill the foundation concrete surface to ensure that the ground slope meets the drainage requirements and prevent water accumulation.

Q: What impact does the milling width of road milling machine concrete scarifier have on construction?

The milling width of road milling machine concrete scarifier determines the coverage of a single operation. Wider milling width can improve construction efficiency, reduce the number of operations and construction time, and is suitable for large-area and long-distance road milling projects, such as highway pavement renovation. However, wide-width milling machines have poor flexibility when operating in small sites or complex terrains, while narrow-width milling machines are more suitable for fine operations such as narrow areas or local repairs.

Q: What preparations need to be made before operating a road milling machine concrete scarifier?
Before operating a road milling machine concrete scarifier, check whether the engine oil, hydraulic oil, water tank water level, etc. are normal; check the wear of the tool and replace the damaged tool in time; debug the depth adjustment device and travel control system to ensure their accuracy; clean up the debris on the construction site to ensure that the site is open and free of obstacles; operators need to be familiar with the equipment operation manual, understand the functions of each control button and instrument, and wear safety protection equipment.

Q: How to maintain and replace the tool of a road milling machine concrete scarifier?
After using the tool of a road milling machine concrete scarifier, the attached concrete debris should be cleaned in time and the degree of blade wear should be checked. Sharpen the tool regularly to keep it sharp. When the tool is worn to a certain extent, the cutting efficiency is significantly reduced or it is damaged, it needs to be replaced in time. When replacing, make sure that the new tool is installed firmly, arranged correctly, and fits tightly with the milling drum.

Q: What are the key points in the maintenance of the hydraulic system in the road milling machine concrete scarifier?
The maintenance of the hydraulic system should regularly check the hydraulic oil level and oil quality, and replenish or replace the hydraulic oil in time; check whether the hydraulic pipeline has leakage, damage, and whether the joint is loose; clean or replace the hydraulic oil filter to prevent impurities from entering the system and affecting the normal operation of the components; regularly debug the performance of hydraulic pumps, valves and other components to ensure that the pressure of the hydraulic system is stable and the flow is normal.
