DOAN machinery as the asphalt pavement maintenance industry's technology leader, in 2006, independently developed the first intelligent linkage control of asphalt and gravel sprinkling (cloth) of the synchronous seal car, the formal product to fill the "China to create" After 10 years of technical sedimentation and accumulation of experience,Road Cutting Machine their quality, has been the formation of asphalt gravel sync sealing car series of product clusters, respectively, for the city, the main line, the main road, D385250TFC-T384A, DGL5251TFC-T385A, as well as the new road, highway maintenance DGL5310TFC-T424 type, especially in order to meet the large area, high-intensity continuous construction requirements and specially developed a new DGL5250TFC -T454 Asphalt Crushed Stone Synchronization Seal Car. The above models can meet the different needs of users, while relying on reliable equipment, stable performance and excellent market performance, prompted DOAN as bitumen gravel synchronous seal car national standards drafters and makers.
At present, in order to solve the needs of many new and old customers, such as tight schedule, multi-purpose and continuous improvement of construction quality, the DOAN R & D team, on the basis of the stable, reliable and precise characteristics of the old section asphalt- The company has successfully developed the world's highest technology,Road Router Crack the best technology DGL5250TFC-T454 asphalt gravel synchronous seal car, which not only has the largest domestic asphalt tank (10000L) + stone silo (13.5m ³) Can greatly improve the construction efficiency, and also has the maximum synchronous seal width of 4500mm, at the same time to meet the high-precision rubber asphalt sprinkler requirements, is the real domestic and foreign rubber asphalt to the most high-end asphalt gravel synchronization seal car.
The equipment chassis is mainly used in the heavy truck chassis of Shaanxi Auto, with high power, strong bearing capacity and strong power. It can be used for stable construction under the big road condition. Asphalt storage tank adopts the special structure designed and developed by itself. The lower the center of gravity of the vehicle,practical concrete cutting machine cost the safety performance, and can adapt to more complex corners and other road conditions; asphalt tank unique dual mixing system, fully achieved the rubber asphalt without dead angle heating mixing effect, while increasing the asphalt heating rate, Completely solve the rubber asphalt in the process of transport and heating rubber particles segregation and precipitation problems; with a large displacement asphalt pump to meet the needs of various conditions, while the asphalt pump speed by program control, as long as the set amount of asphalt and work Width, asphalt pump speed can automatically adapt to changes in vehicle speed, the full realization of intelligent control.
The combination hopper structure as the DOAN first patent, the construction height is low, the volume is big, the center of gravity is reasonable, the work is steady. Compared with competing products, the length of the machine shortened by as much as 1m while the largest silo volume to maintain, so as to save the user from the loading time, greatly reducing the construction costs, thereby enhancing the construction efficiency; asphalt tank heating double (Sprinkle) cloth, sprinkle (sprinkle) cloth with high precision, spraying (spreading) process by the computer timely full control,high efficient crack router Instructions for use spraying (sprinkling), sprinkler (sprinkle), and so on, The volume is not affected by the speed, to fine work to ensure the quality of construction quality; pneumatic system has an automatic purge function, after the completion of the construction pipeline and spray pipe to purge, the residual asphalt blowing back to avoid asphalt residue, The unique gravel spreading system can make the spreading start more neat, spread more evenly, and the gradient and slope of the construction road have no influence on the spreading amount and spreading width.
