Q:How about roller Qingdao kotai heavy industry.

Good, the price advantage, function and other brands also have more than one. But I personally think that the price is better than Lu Tong and Liugong, lonking, xiamen. In particular, 20 tons and 22 tons of mechanical vibration single steel roller, the reason why I say this particular, because this is generally recognized by the market, relatively hot models, but also comparable,

Q:Classification of rollers

The utility model is suitable for various compaction operations with the gravity action of the machine itself, so that the compacted layer is permanently deformed and compacted. It is divided into two types: steel wheel type and tyre type. Grinding wheel grinding, grinding groove structure light and kneading etc.. Light milling is the most common and is mainly used for pavement surface compaction. With mechanical or hydraulic transmission, the utility model can concentrate the compacted part of the protruding part, and has high compaction and smoothness, and is suitable for the compaction operation of the asphalt pavement. According to the layout of the axle, there are single shaft, single wheel, double shaft, double shaft, three wheel and three axle, three wheel and so on. The internal combustion engine is powered by mechanical or hydraulic transmission. General front wheel steering, good maneuverability, rear wheel drive. In order to improve the steering and rolling performance, the articulated steering structure and all wheel drive should be adopted.

Q:How many grade roller are selected for the last roller compaction of subgrade filling?

Different highway grade requirements are different, general 20T total enough, if there are special requirements, the grinding of the drawings will be given

Q:What is the difference between single drive vibratory roller and double drive vibratory roller?

Single roller drive power walking as double drive, work quality is better than double drive, not as efficient as double drive, work efficiency of vibration frequency of surface quality is not a level difference between a lot of professional roller, the hope can help you

Q:XCMG alarm lamp for vibratory roller

As the global economy is still in a slow recovery period, coupled with China's Roller Road enterprises export major market recovery is weak, in 2013, the road roller exports situation has improved, but the growth rate is weak. In 2013, the roller main production enterprises exported 3395 rollers, an increase of 1.8%. More than 200 enterprises export roller this year, Xugong, Xiagong, Liugong, Luoyang Road, Liuzhou, mountain and other 6 enterprises. This one, because of the influence of brand and overseas channels, up to 752 units of export Xugong roller, total sales of 18.5%; export 693 units Xiagong roller, has accounted for 42.6% of total sales; Liugong exports 556 units accounted for 39.85%.

Q:How often does the roller change the engine oil? Is there a master pointing at one or two?

Your roller oil change cycle is usually 250 hours to replace!! The 250 hours here are a cumulative amount of work hours per day!! At the same time for changing the oil filter!!! If the environment is too bad (sand dust serious) can be replaced in advance. If you work less than 250 hours a year, suggest changing it once a year!! But it's a job of less than 250 hours a year, so I suggest you sell the roller!! Ha-ha！！ I hope I can help you!!

Q:In the practical process, which one is the most practical? May I ask who can help me explain?

the airport runway and the F1 track level is not the same, the higher the level, the higher requirements on and micro the overall structure of the pavement radian, the rubber wheel can be very good to meet these requirements, of course, only in the high requirements of the road we can see this kind of roller, usually in the side is not to see

Q:Do we have to use rubber wheels? Is there a mandatory rule?The fine-grained AC-13 is ready to let the builders use the rubber wheel, but the builders say the rubber wheel is rarely used. Would I like to know if this is necessary?

2. The rolling principle of the rubber wheel is different from that of the steel wheel. The rubber wheel can better improve the density3, from the perspective of engineering quality, the construction party should take all kinds of effective equipment and facilities to improve the quality of the project

Q:What does the triple wheel drive overlap the rear wheel 1/2?

The width of the wheel roller (rear) is half a can crush the width of 31 SSR200AC-8 double wheel, double amplitude vibration mode.

Q:How many tons of pressure are there when they are opened?For example: take a site earthwork flat, 20 tons of press vibration can affect on soil 30cm within the excavation area of soil compaction?, not loose.

In addition the roller roller and hydraulic machinery driving the same tonnage hydraulic roller die weight (can be simply understood as the effective work the weight of the steel wheel) greater. Effect of depth.
