Small Hydraulic Milling Machine In Highway Maintenance Application
Small road Milling Machine As highway and urban road maintenance of special equipment
, is the addition of large open Milling Machine (Milling width greater than 50cm, single milling depth is greater than 5cm) away, in a small area within the working area Milling and no material recovery road Picking the special equipment. With large milling machine working principle of different anti-cutting, small milling machine is to rely on the forward high speed milling drums, milling drum to lashing a carbide cutter blade shaft quickly and repeatedly hit the road, use of alloy blade inlaid tungsten steel alloy tip to broken teeth and grinding road surface material, so as to achieve the effect of milling.
Small milling machine Main features: Clear and peeling asphalt pavement rutting, cracking and oil package; milling road markings and road blocks of cement between the milling station and the road Picking the wrong address.
Due to user habits and domestic demand constraints, milling machine late in the development of our country until the beginning of this century, in Hunan and Jiangsu and Zhejiang Provinces, only individual firms imitate and learn from similar products manufactured overseas relatively simple small milling machine, milling width of mostly 20cm, milling depth of 3mm-5mm between the full mechanical drive, no depth of cut and run control system, which was mainly used in flooring of galling processing, highway Construction of Pavement leveling Evenness treatment.
As China's highways and urban road construction and development, combined with the domestic user habits, fast high-quality Pavement Maintenance Operating a road transport and industry, municipal administration and of the important issues concerned, so start small road milling machine with market demand.
Changsha Construction Machinery is the state building earlier commitment to research and production of professional manufacturers of small milling machine, the company produced ZP250H, ZP350H two milling machine is currently stable with a localization rate of 90% or more of the small hydraulic milling machine. The maximum milling width of 350mm, with 25 horsepower gasoline imports Engine , With imports of hydraulic pumps and Motor , Depth of cut and milling drum machine can realize stepless speed control of walking. C50 concrete to reach the largest single milling depth 15-20mm.
Case: long interest in Hunan Highway K85 +120- K96 +000 range, because the cement board for non-consecutive road leading to the large height difference between the cement blocks, bridge or very serious, long-Yi Highway management company of a trial ZP250H milling machine, specifically the joints between blocks of cement milling, milling machine between the depth of 1cm-5cm. The field effect is good, then use a purchase of 4 National Taiwan University area. This section of vehicles jumping solve the problem.
Since the user habits and lack of understanding of products in our municipal management and highway maintenance company's maintenance machinery configuration, the small depth, small-scale milling operations, the current is usually taken Skid Loader Then work with a milling head of portfolio allocation. However, the cost of this configuration is very high, a single milling head (usually working width of 35cm-45cm) are priced at 10 million yuan. But also by the slip Loader Body size and turning radius of influence, even small-scale milling operations had to rely on artificial operation to complete. Because of the small hydraulic milling machine to buy low cost, flexible operation, and easy to use, more and more number of municipal and highway maintenance users. Small hydraulic milling machine will be in the future maintenance of roads and municipal roads get more and more widely used.
