Safety operation procedures of asphalt paver?

1, all safety protection facilities on the paver must be fully equipped. After the screed is extended, corresponding safety protection measures should be taken. The width of the pedal must be equal to the width of the paver.

2, the cab and the work site should have a wide field of vision, remove all obstacles that hinder the work. During the operation, irrelevant personnel shall not stay on the bridge. Operators shall not leave their posts without permission.

3, when the truck to the paver unloading, should coordinate action, synchronous, to prevent collision.

4. It must be moved when the paver stops completely. Forcible shifting and ramp shifting or neutral taxiing are prohibited.

5. When the paver is working, the driver shall not leave the bridge, and irrelevant personnel shall not get on or off during the operation.

6, wheel paver with differential device, should be used when the ground adhesion is insufficient, and must stop when combined with differential device or disconnected. When the differential device is combined, only straight lines are allowed, and no turning is allowed.

7, screed preheating, attention should be paid to control the heat, to prevent deformation due to local overheating. No matter what heating method is adopted, each ignition and heating time shall not exceed 45 minutes. In the process of heating, there must be someone to look after it.

8. The system pressure of using compressed air to inject fuel to preheat the screed must reach the specified value. After the burner is ignited, the blower and damper can be started to burn completely.

9, preheating, should strengthen the observation of the combustion situation, if the flame goes out, should immediately turn off the fuel or gas switch, find out the reason, troubleshooting, and discharge the spilled fuel or gas rear can be rekindled.

10, the components of the automatic leveling device should be used carefully, and collision, rain and dust damage must be prevented.

1 1. Drive as smoothly as possible and don't make sharp turns. During curve operation, the distance between the end of ironing device and kerb shall not be less than 10cm to avoid collision.

12. When the paver is working on a big slope (vertical and horizontal gradient is 15%-20%), special safety measures should be taken to ensure normal operation and prevent accidents.

13. When working on a steep slope, reduce the amount of mixture in the hopper and work at 50% of the rated paving capacity, while controlling the driving speed and turning radius.

14. When paving on the cross ramp, the screed on the downhill side should be extended, because the mixture will automatically flow to the downhill side. In order to prevent the mixture from flowing to the downhill side automatically, spiral blades in the same direction can be used on the left and right sides.

15. In order to prevent the paver from tipping over, if necessary, a heavy tractor or bulldozer can be connected to the paver with a steel wire rope and run parallel to the paver at the top of the slope at a constant speed.

16, paving should be done from low to high when working on normal longitudinal slope. If you have to work downhill, you should work closely with the car driver to strive for a stable speed.

17, crawler pavers shall not travel long distances, and the driving distance shall not exceed 1km. If there are special needs, long-distance driving should be carried out, and the walking and hydraulic devices should be cooled. If the width of the screed exceeds its basic width, during the transition of the paver, a corresponding counterweight should be set in the hopper to avoid damaging the roller and driving wheel.

18. When the paver is towed by other vehicles, only rigid traction rods are allowed, and steel ropes are not allowed. The shift lever should be placed in neutral, and the automatic device should be deactivated.

19, it is forbidden to use paver to pull other machinery.

20, cleaning work must be carried out outside the job site. When cleaning the paver with diesel oil, it is forbidden to get close to open flames.

2 1. Before leaving the bridge, the driver should stop the paver, the parking brake must be reliable, the two side walls of the hopper should be completely below the square, and the screed should be placed on the ground or hung with a hook.

22, disassembly and installation of paver must follow the relevant safety regulations of repair and hoisting; Transshipment and haulage shall comply with relevant traffic laws and regulations, and shall not be too wide, too high or overloaded.

23. When the paver is parked near the driveway, it is necessary to set up obvious safety signs around it, set up light signals at night, and guard it by designated personnel.
