Pneumatic smooth-tire rollers are suitable for compaction of various cohesive and non-cohesive materials such as sandy soil, crushed stone, stabilized soils, bituminous concrete and rolling cement concrete (RCC) on road surface construction, especially for final compaction of asphalt surface on high-class highway，which are super quality compaction equipments for high-class highway, airport, municipal road and industrial ground.
Powerful CUMMINS B series diesel engine for various working conditions.
Hydrostatic travel drive with imported hydraulic pump and motor at two-range infinitely variable speeds results in less shock to road surface.
Operating weight and ground contact pressure can be adjusted by filling water or wet sand with greater adjusting scope.
Power sprinkler system with corrosion free materials and reinforced polyethylene water tank and multi-stage water filters for reliable operation.
Unique, beautiful and compact appearance design .
Spacious and closed operator's cab with ventilating and air conditioning devices (optional).

- Q: How to prepare the contract, pay the monthly rent, if there is a dispute how to do, how long will it take to recover the cost, the risk of investment in road rollers large?I recently wanted to buy a 20T vibratory rollerLiugong 20 tons hydraulic vibratory roller brand new, because I have a number of visits, feel domestic, more convenient maintenance cheaper, domestic brands Liugong prices at reasonable prices, quality is also good!
- My view is Xugong, Shandong Shantui machine reputation is also good, you can rent what type of machine, hydraulic cylinder wheel vibration of the rent of 12000 yuan, 17000 yuan in rent type, double cylinder wheel rent of 40000 yuan, the price is in season, the off-season would go bad. I'm also thinking of buying a roller with a rubber wheel. I hope we can talk to each other
- Q: How many tons are there in the maximum roller?
- There are more than 30 heavy duty roller rollers, such as XP302.Press machine road normally rolling efficiency and the compaction effect is proportional to its mass, so for higher grade, compaction material is complicated and the construction cycle is short of the road should be considered roller of large tonnage, construction equipment and large tonnage roller is the construction unit of the project bidding must be available, so in general should consider buying weight above 14T, the exciting force of more than 260kN wheel drive single drum vibratory roller. But it is not the exciting force of the bigger the better, because the exciting force will lead to segregation of surface layer, loose aggregate crushing and grading materials, not only reduce the compaction quality, but also can cause premature fatigue of drivers and machine parts damage, experience has shown that effective excitation maximum should not exceed 400kN.
- Q: Rules for the operation of rollers
- 10. Other operating requirements shall comply with the requirements of the hydrostatic roller.No matter whether it is uphill or downhill, the bottom layer of the asphalt mixture must be clean and dry, and the asphalt binding layer must be sprayed to avoid sliding when the mixture is rolled.No matter whether it is uphill rolling or downhill rolling, the driving wheel of the roller should be behind. It has the following advantages: uphill, the driving force behind the driving wheel can withstand ramp and machine provided by their own, while the front wheels were initially on compaction, to withstand the large shear force driving wheel produces; downhill, impact roller weight generated by the driving wheel brake offset, capacity only by the mixture compacted to support the front wheel driving wheel produces shear stress.When rolling uphill, the start, stop and acceleration of the roller must be stable, so that the speed is too high or too low.Before the uphill rolling, the mixture should be cooled to the required low limit temperature, and then static preloading shall be applied. When the mixture temperature drops to the lower limit (120 DEG C), the vibratory compaction will be adopted.The sudden change of speed and braking should be avoided in downhill rolling.The slope is very steep downhill in rolling case, should use light roller pre pressure, followed by heavy rollers or vibratory compaction.
- Q: What's in the roller in front of the roller?
- Inside is a set of eccentric mechanisms that vibrate by eccentric rotation with frequencies between 25-50HZ.
- Q: Where is the driving wheel of the steel roller?
- Different manufacturers design is different, some single drive, some double drive, as if the single drive is generally the latter drive
- Q: in order to increase the pavement permeability, the total mass of not less than 25 tons.
- For dense bituminous mixture aggregate due to small and continuous gradation, the tyre roller has the rubbing function makes the compaction layer of particles without destroying and interlocked, uniform and compact.
- Q: Working principle of vibratory pump and vibrating motor
- To an eccentric rotor to rotate, so there is a shock.
- Q: What is the cause of soil cracking when subgrade is pressed by subgrade?
- When the moisture content of backfill material is too large, cracking occurs in the course of pressing, and it will become loess when it is serious. The optimum moisture content of backfill is between 9% and 11%.
- Q: That will not corrode the pavement, such as diesel oil, salad oil as are oil corrosion, although not corrosion of asphalt, but the corrosion wheel is not good, who have the sticky proof measures better, thank you "Nd}S + E, bbs.3c3t SqS + H human Y ~ ~ V
- Tyre roller is not allowed in modified asphalt pavement!! If forced to use, the only way is that the rubber wheel is opened slowly, followed by three people holding a mop covered with diesel, while walking on the rubber wheel above, this is the only non stick method. But pavement damage is not recommended. The biggest drawback is that the modified asphalt mixture rolling temperature is more than 150, and the tires are also damaged. Therefore, the specification is not allowed. (tyres, tyres, nearly smooth, without lines)
- 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
