Q: I recently wanted to buy a 20 ton roller, but I don't know which one is better Now know, a long work, ha, Liugong, but they say roller their good, here also please comment: Of course, xugong:1, Xugong good job, the opportunity is relatively more;2, Xugong sales volume, accessories good buy;3, Xugong buy a new car, usually expensive 2, 30 thousand, but when selling old cars, the same is still expensive so much, and once become an old car, basically only Xugong sell well, other cars when the scrap metal more;4, XCMG road roller generally longer than other brands for a few years, in fact, do not have more, even if a long year, one year's additional income is how much ah, 20 tons of steel wheel press less than 10 tens of thousands of it. Mechanical roller generally in the life of 10, a few 20 years, even if the Xugong longevity 10%, not much, at least 1 years ah.Who do you think is worth it?No more, just believe in the masses,The judgment of the masses is accurate,XCMG has been in China for the first time in nearly 30 years. Why not other brands?It's not like buying a toy for a child.Even if is the short-term behavior, with 1, 2 years away, can not buy brand-name, is at work, a problem, can not repair parts, people can't even delay money!What you think?

Q: I would like to ask, 18T roller layered centimeters, compaction is the most appropriate?: 18T roller is 300 cm layered and compacted most suitable

Q: Roller operation method: In the following, the data and performance of DD-110 vibratory roller in highway construction are analyzed. 1 DD-110 double drive double vibration effect of 1.1 double drive active material is the pressure force of wheel H '=H and R' R '=R, vertical force on the compacted material, while the level of H' is the material driving force to the roller to move in the opposite direction, the mobile will be the driving wheel has been compaction of material resistance, the granular materials are pressed in high pressure moving close to the vertical line of the roller interval, thus forming the wavy surface of the driving wheel is not before, the compactness of the surface material will be fairly flat. Because the DD-110 roller adopts two wheel drive structure, with the excellent performance of compaction, does not produce the phenomenon of wave, so as to ensure the smoothness of pavement compaction, so also will the drive roller is called non corrugated roller, which is a rigid index must reach the highway. 1.2 double vibration vibration make the internal friction material pressure was dramatically reduced, shear strength decreased, so the compressive resistance is very small, very easy to be out of gas pressure in the material and liquid, which are embedded in crowded compacted. Because DD-110 has the function of double wheel vibration, the compacting efficiency can be greatly improved in the process of compaction, and the asphalt pavement is more favorable for the forming of the road surface and the quality of the construction.

Q: Roller roller steel what material? Thickness 10mm or so, which expert pointing Q235, OK?: High manganese steel has a strong work hardening, such as surface hardness of 200HB high manganese steel, after the impact of the rapid formation of hardness of 500HB hardened layer,

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: Vibratory roller pressure and steel roller compacted what is different: You should make the cement stabilized layer of double steel wheel vibratory roller, you should first use vibratory roller vibration compaction, and then do not open vibration to smooth surface. Just do not open the vibration pressure several times, the static pressure only to surface dense, but the bottom is still more loose

Q: What is a roller?: The road belongs to the road equipment in construction machinery category, widely used in Embankment Compaction of highway, railway, airport runway, dam, stadium and other large projects, can crush sand, semi viscous soil, the stability of subgrade soil and asphalt concrete road surface

Q: Excuse me, is there a 80 ton heavy duty roller?: According to the roller weight, there is no 80T heavy roller. For the moment, the heaviest vibratory roller has a weight of about 28T, and the heaviest tire roller has a weight of 35T.

Q: Brief introduction of tyre roller: The compacted asphalt mixture conforms to the requirements of compactness and smoothnessSelect reasonable roller combination method and rolling steps to achieve the best results. The asphalt mixture is compacted by a steel cylinder type static roller and a tire roller or a vibratory roller. The number of rollers is determined according to the production site.The compaction of asphalt mixture is carried out in three stages: initial pressure, compound pressure and final pressure (including molding). The roller is rolled at a slow and uniform speed.The initial pressure of asphalt mixture meets the following requirementsThe initial A. pressure roller soosai eng DD-110 in mixture paving after high temperature, and shall not have any time, hair crack, compaction temperature according to the consistency of asphalt, roller type, temperature paving layer thickness, mixture type is determined by the pressure test with test.B. roller is rolled from the outside to the center. The adjacent rolling zone should overlap with 1/3 - 1/2 wheel width. At last, the center part of the rolling road will be compressed at full amplitude. When the edge of the baffle, kerb, shoulder and other files, should be close to the file roller. When the edge without retaining, can mix the edge rake rake slightly high, then the outer wheel roller rolling out 10cm above the edge.

Q: Who knows, what is the best way to press the water stable?: The current widespread use of single steel wheel roller compaction water stability, but if the water layer thickness is less than 25cm, you can use the double steel wheel Dynapac compaction, compaction mode with low frequency and high vibration, the efficiency is doubled.
