Recently, our city is full of activities to create health and creativity, and the first thing to do urban beautification is to build roads. If you want to repair the road well, you can't do without the use of a 2 ton driving roller. Let's take a look at how the roller is used.
1. Whether it is uphill or downhill, the bottom layer of the asphalt mixture must be clean and dry, and the asphalt binder layer must be sprayed to avoid slippage of the mixture during rolling.
2. Whether it is uphill crushing and rolling down the old slope, the driving wheel of the roller should be behind. This has the following advantages: when going uphill, the rear drive wheel can withstand the driving force provided by the ramp and the machine itself, while the front wheel preliminarily compacts the road surface to withstand the large shear force generated by the drive wheel. When going downhill, the impact force generated by the self-weight of the roller is offset by the braking of the driving wheel. Only the mixture after rolling by the front wheel has the ability to support the driving wheel to generate shearing force.
3. When rolling uphill, the starter, stop and acceleration of the roller should be stable, avoiding too high or too low speed.
4. Before the uphill rolling, the mixture should be cooled to the specified low temperature, and then static preloading is carried out. When the temperature of the mixture drops to the lower limit (120 °C), the vibration compaction is adopted.
5. Downhill rolling should avoid sudden shifting and braking.
6. When rolling downhill under steep slope conditions, the light roller should be used for pre-pressing, and then compacted by heavy-duty roller or vibratory roller.
How is the 2 ton driving roller used?
The 2 ton driving roller is a kind of mechanical equipment. All mechanical equipment must be well maintained, so that it can grow its life. Let's take a look at how the 3 ton driving roller is maintained.
1. The road roller checks the tire pressure and damage;
2. The road roller checks the instrument and the light;
3. Press the butter at each hinge point;
4. The road roller checks for oil, water, gas leakage and signs of overheating of the machine;
5. The roller checks the diesel engine oil, coolant and hydraulic fluid levels.
The above is the use of the 2 ton driving roller. Do you understand? For more information, please call for detailed consultation. (This article is from Situ Rick)
