Overview: for the laying of asphalt or workshop on the deck of the old concrete ground before re-paving the concrete, remove the cement floating slurry and flatten the nap, but also used to remove the construction of the hard residue left in the construction. Features: Spindle bearings use internationally renowned NSK spherical spherical bearings, to ensure that the machine to adapt to strong load, high speed working conditions; blade using imported high-quality carbide, sharp wear, long life; Connection, torque shock resistance; single bearing support, machine edge performance is better, more suitable for construction within the workshop; depth adjustable, rotation depth adjustment wheel can be.

With the increase of the mileage of expressway in China, the rapid development of urbanization, the increase of road reconstruction work in large and medium cities, the road cold milling machine as one of the main models of road maintenance projects, its advanced technical performance, High efficiency, simple construction methods, has been more and more attention by the construction unit. According to the engineering machinery industry statistics, at present, the number of cold milling machines used in our country is at least 3,500, and the number of 250-300 units is increasing every year. Domestic construction units have been out of manpower and milling machine difficult to choose the stage, now consider how to use the milling machine, looking for more efficient construction methods. China's road cold milling machine industry market prospects, milling machinery supporting parts and tools market promising.
Milling is one of the main consumables in the process of milling machines. The reasonable design and proper use of the milling teeth have an important effect on the working efficiency and construction quality of the milling machine. At present, the domestic cutting production enterprises on the milling teeth, especially the structural design of concrete milling teeth, cloth form lack of in-depth theoretical analysis, affecting the milling effect and picking and tooth seat life. Reference to foreign advanced drilling production enterprises of similar products, to develop design ideas, and thus improve product performance, to produce their own characteristics of the milling cutter will help.

Because sometimes design, selection and construction quality of the wishful, more quickly the frequency of the occurrence of the disease. If these diseases are not repaired in time to restore the basic functions of the road, not only will affect the traffic flow, but also to accelerate the expansion of the disease, greatly improving the cost of repair works. Therefore, the timely repair of asphalt pavement has become one of the increasingly important priorities of highway maintenance units.Double Steel Roller - Road Machinery Equipment Manufacturers - Doan Machinery
Cold and modified asphalt solution repair pit, without heating, to achieve a cold oil, cold materials, cold mix. The car in the operation can be based on the base layer, grass-roots, surface layer of the different requirements of free gradation, mix out to meet the requirements of the base layer, grass and surface materials. The car can use the vehicle to carry the equipment to make the asphalt pavement repair process to complete a one-time. Since the success of research and development, has been in Shanxi and a number of high-grade highway to promote the application, received a good effect. As the main designer of the device, the author will be its main performance, structure and functional characteristics described below. !!"!car.!"# Hydraulic ramming hammer, hydraulic grasping 91 hydraulic pump station for hydraulic ho, bucket to provide hydraulic power. Hydraulic hammer for the use of road cutting machine, from the crushing effect; hydraulic ramming hammer for tamping the material, especially the pit dawning of the solid; hydraulic grab for stone, water stability and the machine to carry the lifting equipment.

There is no doubt that high-grade roads, especially the highway repair, only the use of the application of multi-functional conservation machinery to complete, which is to ensure the construction quality and improve the efficiency of the only choice, but also to achieve highway management modernization and civilized construction of important guarantee and premise The Multi-functional integrated maintenance vehicles to repair the classification can be divided into hot and cold operations two. With the continuous development of science and technology, cold repair mode of operation with its many advantages increasingly praised by the highway engineering academia. And Shanxi Provincial Highway Bureau Jinzhong Branch and Shanxi Hualong Traffic Technology Co., Ltd. recently developed successfully It is mainly used for forced mixing of asphalt mixes and water stabilizers. For the base layer, the base of the hopper by the (hopper composition, and the surface of the different requirements of the ratio of stone, gravel, cement storage.
