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: Roller operation method: In the highway construction, the rolling process is a process with large amount of input and the most quality and technical index requirements, especially for the construction of the asphalt pavement. The construction of asphalt pavement mainly includes mixing, paving and rolling three aspects. And compaction is an important link, and it has an important impact on the technical indicators, such as flatness, density and so on. In order to achieve good quality indexes in the process of compaction, it is necessary to have a comprehensive understanding of the selection of roller and the performance of each type of roller. We in the construction of highway pavement asphalt bole, through demonstration and practice of other units equipped with Ingersoll Rand DD-110 vibratory compaction machinery as the main highway in Bole high speed and high quality paving has played an important role.

Q: Roller three tons, what kind of good?: It's good for Sakai to vibrate both before and after. Vibration can be separated from front to rear.

Q: In the process of asphalt pavement construction, can the wheel roller use diesel oil to clean the surface of the wheel?: Generally, the use of steel roller, use plain water cooling and surface cleaning, the use of rubber tire roller, the use of diesel oil, it is only in the beginning or sticking wheel rolling, rolling wheel, after a while, the surface temperature, there is no need for.In the rolling, mainly by spraying some solvents make the wheels not sticky asphalt mixture, like diesel, oil film of asphalt mixture is damaged, and the cost is high, the construction unit and the use of rapeseed oil, water washing powder, the specification also mentioned some. In general construction, more diesel and water ratio of 1:1 solution is used.

Q: Excavators, forklifts, bulldozers, rollers with the same tonnage fight who badly rank: Forklift tire chassis is running fast, but slow dig smart strong activity, only roller rolling speed is also slow, bulldozing clever activity than low thrust but also digging machine.

Q: The front wheel diameter of the roller is 1.6m, and the width is 2m. What is the area of the roller that rotates for one week? M2: Solution: it is known that the front diameter of the roller is 1.6 meters and the width is 2 meters,The front wheel is rotated for one week, the area of the roller = the front wheel's perimeter * width=3.14 * front wheel diameter * width=3.14 * 1.6 * 2=10.048 square metersA: the front wheel is rotated for one week. The area of the roller is 10.048 square meters.

Q: The role of rubber tyred roller is used for water steady rolling: The main difference between the three is to use the site and use the different processes

Q: Why should we use the rubber tyred roller in the construction of the asphalt pavement?: At present, the latter two are widely used in construction.The following is a steel wheel roller, which is in front of the paver. The following table shows two rubber tyred rollers. Roller's purpose: 1. to achieve the required density (usually controlled by compaction); 2. press out the smooth surface.General compaction includes initial pressure, re pressure and final pressure. The final pressure is to remove the traces of rollers, the road is kept smooth, generally can not be omitted, and the use of steel wheel roller. If the initial pressure can meet the density requirements, there is no need to re pressure, but generally still maintain these three steps.

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: How is the tonnage of the roller machine calculated? Forget to know the answer! Thank you: Compaction performance can not only look at the total weight, but also depends on the amplitude, vibration exciter, steel wheel load a number of factors. The same tonnage, general hydraulic double drive roller than mechanical roller pressure strength.
