Precautions For Safe Operation Of Road Roller


Before the road roller works, release the parking brake and put the gear lever in the middle position. Check the braking and steering functions of the road roller, which shall be sensitive and reliable. The mud scraper of the road roller shall be flat and excellent. Before starting, there should be no stagnant and irrelevant personnel around the road roller. When the road roller needs to change the front and rear driving direction, first turn off the vibration switch, and then carry out the direction conversion operation after the road roller stops. It is forbidden to use the reversing clutch for braking. In case of emergency, the rear wheel brake of the road roller can be used as the emergency brake. When the road roller rolls on the new road, it shall roll from the center to both sides. The rolling shall not be too close to the edge of the subgrade, and the distance from the edge of the subgrade shall not be less than 0.5m to prevent collapse.

When the road roller goes uphill and downhill, the gear shall be selected in advance. It is forbidden to shift gears on the ramp, and it is forbidden to shift, slide or slip down the slope. Do not use the road roller to drag other machinery or objects. When two road rollers drive or roll on a flat road, the distance shall be kept at more than 3m, and column driving is prohibited on the slope. To prevent accidents caused by brake failure or sliding slope. When using a tire road roller, care should be taken to maintain the normal pressure of the tires and whether there are any stones between the tires. It is forbidden for the road roller to vibrate on a solid road. The starting or stopping vibration of the road roller shall be carried out during driving to avoid damaging the flatness of the pressed road surface.
