?Pavement milling machine is one of the main models of asphalt pavement construction machinery, mainly used for highway, urban roads and other asphalt concrete surface removal package, oil waves, textures, rutting and so on. It is one of the most economical modern maintenance methods. Because of its high working efficiency, simple construction technology, easy to control the milling depth, convenient and flexible operation, good maneuverability, Milling the old material can be directly recycled, etc., which is widely used in urban municipal roads and highway maintenance projects. Customers in the purchase of milling machine, in the course of continuous use will inevitably occur consumption and wear, in order to extend the service life of the machine, the correct operation and proper maintenance is necessary, here some of the milling machine maintenance experience and We share. 1, to extend the road milling machine life measures First of all, the machine must be operated by professionals, and carefully read the operating manual. 2, milling machine The main part of the machine due to milling cutter, bearings, gaskets, drums, the operation process due to a long time with the road friction, the fastest consumption is this part of the regular replacement, check to better Extend the service life of the machine. 3, to extend the road milling machine life measures should be checked daily, if the above grinding out of the slot more than 25% of the diameter of the knife, you have to replace. In general, the life of the knife shaft is half the life of the tungsten steel cutter. From the square area, the life of the milling depth of 5mm when about 350-500 square meters. But please pay attention to, there are many factors that will affect the life of the knife shaft, so to check every day. 4, milling machine For safety reasons, before the maintenance, should first pull the engine spark plug, preferably by qualified mechanics. 5, to extend the life of the road milling machine measures every time before the operation to check the oil level, milling machine to clean the air filter after use information solar transport facilities electric concrete table vibrator asphalt crack repair tape highway construction equipment crack sealing
