Q:Classification of rollers
The front wheel frame is hinged with the frame to reduce the unusual body sway of the road surface. The rear wheel and the frame are rigidly connected. Hydraulic control, hydraulic cylinder control steering. The front and rear grinding wheels are equipped with scraper to remove the adhesive on the roller. A sprinkler system is also provided for compacting the asphalt pavement by sprinkling the wheel to prevent adhesion of the asphalt mixture. To increase the force, but also in the grinding wheel with iron, sand, water and so on, increase the weight. The main technical parameters of steel wheeled roller are weight and line pressure. In 80s, all kinds of steel wheeled roller, machine weight range is about two wheeled roller 2~13 tons, three wheeled roller 1~15 tons, according to the requirements can be pressurized 1~3 tons, three axle roller press 13~14 tons, the pressure is 18~19 tons after weight. The roller is made of pneumatic tyres, usually with 3~5 front wheels and 4~6 rear wheels.
Q:How much is the front toughened 20t vibratory roller in the old section?
Glass cheap, depends on what you are glass front or side of the professional roller
Q:Where can I find a road roller in Yuncheng?
What size rollers do you need, and general roller manufacturers are concentrated in some provinces and municipalities?.Yuncheng, if there is no suitable road roller manufacturers, or suggest you outsource, looking for professional manufacturers can
Q:What are the classification methods of vibratory rollers?
Number of steel wheels: single steel wheel roller, double steel wheel roller, big steel wheel roller (rear tyre drive)Drive: mechanical vibration, hydraulic walking, full hydraulic (hydraulic, vibration, hydraulic walking)
Q:Roller cylinder is cylindrical, the width of the drum is 1.5 meters, the cross sectional diameter is 1.2 meters, if every minute to 10 laps, then 1 when the pressure of the road surface number of square meters?
Solution: the bottom perimeter is 3.14 * 1.2=3.768 (meters)The lateral area of the cylinder is 3.768 * 1.5=5.652 (square meters)10 turns per minute, you can find one minute, the area of the road is 5.652 * 10=56.52 (square meters)1 hours =60 minutes56.52 x 60=3391.2 (square meter)Answer: 1 hours, 3391.2 square meters of road surface pressure
Q:How to prevent the construction of road roller crushing rain water pipes? Fifteen
I am not a professional, but I have seen, they are the bottom of the shop, and then pour concrete pouring, a pipe down, and so on when the concrete strength, and then pour asphalt, and then over-voltage road machine
Q:What are the different road tire pressure machine and single pairs of steel wheel roller action?
Rubber roller and double steel roller is generally in asphalt concrete pavement use; rubber tire roller plays a role, enhance the degree of fit between aggregate and asphalt concrete, reinforced compactness; double steel roller has the effect of asphalt concrete.
Q:Road engineering, soil compaction and road roller / Diesel / what is the difference between the two rolling?
To meet the requirements of doing subbase filling and rolling; including earthwork backfilling, bulldozer, layered rolling to meet the design requirements of the degree of compaction, the smoothness of the road not good.No double counting, for example, road subgrade backfill, backfill compacted well, if you want to do is road subbase, rolling, if it is not just the general fill roadbed RCC.
Q:18T roller
Your question is incomplete. If it is a vibratory roller, it can be divided into double wheel and single steel wheel. Single steel wheels are used in earthworks and crushed stone subgrade. Double steel wheels are used on asphalt.
Q:Roller clutch does not move, hang not into gear, what is the problem?
Should be the electronic control gear bar, the pressure is not enough, or power cylinder problems, clutch failure in place, the control sensor will not give the gear signal, of course, can not hang professional roller
