Tamping Rammer

1. The vibration impact compactor should be suitable for compacting loose materials such as cohesive soil, sand, and gravel, and should not be used on cement roads and other hard surfaces.

2. The key inspection items before homework should meet the following requirements:

(1) All components are well connected and not loose;

(2) The internal combustion impact compactor has sufficient lubricating oil, and the throttle controller rotates flexibly;

(3) The electric impact compactor has reliable neutral or grounding, and the surface insulation of the cable is intact.

3. In order to lubricate the components and increase the machine temperature for normal operation, after starting the internal combustion impact compactor, the internal combustion engine should idle for 3-5 minutes, and then gradually increase the throttle until the compactor's jumping is stable before operation.

4. After the electric impact compactor is powered on, the direction of rotation of the motor should be checked, and if there is an error, the phase line should be reversed.

5. During homework, the compactor should be properly controlled and not tilted. In order to reduce vibration to the human body, the handle should not be held too tightly, and the forward speed of the compactor can be controlled.

6. During normal operation, do not press the handle down too hard, as it may affect the height of the compactor. When working on loose fill or uphill, the handle can be slightly pressed downwards and should be able to increase the forward speed of the compactor.

7. In areas where density needs to be increased, the compactor can be controlled by hand to repeatedly compact in place.

According to the homework requirements, the internal combustion impact compactor should change the vibration frequency of the compactor within a certain range by adjusting the size of the throttle.

9. Internal combustion impact rammers should not be operated continuously at high speeds. The internal combustion engine of the impact rammer is an air-cooled two-stroke high-speed (4000r/min) gasoline engine. If operated at high speeds for too long, it will be damaged due to high temperatures. Do not suddenly stop the internal combustion engine while it is running at high speed.

10. Electric impact hammers should be equipped with leakage protection devices, and operators must wear insulated gloves and insulated shoes. When doing homework, the cable should not be pulled too tightly, and the installation of the wire ends should be checked regularly to prevent looseness and leakage. It is strictly prohibited to work in the rain.

During homework, if there is abnormal noise from the impact compactor, the machine should be stopped immediately for inspection.

When transferring short distances, the handle of the impact compactor should be lifted slightly upwards first, and the transport wheel should be loaded into the hook of the impact compactor. Then, the handle should be pressed to tilt the center of gravity backwards before pushing the handle to transfer the impact compactor.

13. After the homework, the mud and attachments on the compactor should be removed, the compactor should be kept clean, and properly stored.
