Road Roller How To Be More Fuel Efficient

AKW GROUP | Updated: Nov 03, 2017

The machine belongs to the category of road equipment in construction machinery. It is widely used for compaction of large-scale projects such as high-grade highways, railways, airport runways, dams and stadiums, etc. It can crush sandy, semi-viscous and cohesive soils, Subgrade stabilized soil and asphalt concrete pavement. Rollers to the gravity of the machinery itself, suitable for all kinds of compaction operations, so that the permanent deformation of the rolling layer is dense. Rollers are divided into two types of steel wheels and tires.

Roller roller compaction of the 6 tips

1. Whether it is uphill or downhill, the bottom layer of asphalt must be clean and dry, and the asphalt layer must be sprayed to prevent the mixture from sliding during rolling.

2. Whether it is uphill rolling or downhill rolling, roller drive wheel should be in the back. Doing so has the following advantages: When uphill, the rear drive wheel can withstand the driving force provided by the ramp and the machine itself, while the front wheels preliminarily compact the road surface to withstand the large shearing forces generated by the drive wheels ; Downhill, the weight of the roller by the impact generated by the drive wheel to offset the brake, only by the front wheel of the mixture after mixing drive wheel has the ability to generate shear force.

3. Uphill rolling, roller start, stop and accelerate smoothly, to avoid speed too high or too low.

4. Uphill before rolling, the mixture should be cooled to the prescribed minimum temperature, and then static preload until the mixture temperature dropped to the lower limit (120 ℃), the use of vibration compaction.

5. Downhill rolling should avoid sudden speed changes and braking.

6. In the case of steep slopes rolling downhill conditions, should be used light pre-roller, and then use heavy-duty roller or vibratory roller compaction

How roller more fuel-efficient

First, to maintain the normal operating temperature of the engine, especially in the cold season, try to keep the water temperature at 75-90 ℃ at the same time in accordance with the seasonal use of fuel.

Second, regular removal of the cooling system scale and pipe and muffler grease and sediment.

Third, the correct adjustment of the brakes, often check the front and rear tractor, tire pressure to maintain normal.

Fourth, to maintain the electrical system, starting mechanism performance intact. Do not idle the engine for a long time, parking immediately turn off.

Fifth, locomotive load should be appropriate. Practice has proved that the load is about 85% of the most fuel-efficient, the most economical, to avoid the phenomenon of "big horse pull cart" or "small horse pull the cart, so as not to waste oil.

Six, choose the appropriate speed. In the light load with "high-end small throttle." Not a big throttle, not speeding.

Seven, a reasonable choice of agricultural machinery, and contiguous operations. Appropriate planning plots and driving directions, to minimize idling, empty driving, detour, stop midway to shorten the total length of homework to reduce ineffective energy consumption.

Eight, timely and reasonable technical maintenance, keep all parts and institutions are often in good technical condition, without sick work.

Nine, purifying fuel, measuring fuel. If the filter before use without precipitation, the impurities in the oil plunger and needle valve will bring harm, so locomotive power, fuel consumption increased. Therefore, the general oil should be precipitated more than 48 hours before use.

Ten, to prevent oil spills. As the long-term use of the machine, the connection parts will appear poor connection, improper assembly, mat damage, loose screws, catheter deformation or rupture, ring aging, will result in oil spills. Therefore, we must take appropriate measures to promptly plug the fuel-efficient.
