How Sag Repair Method Works?

● After the machine is positioned in the sag, lift pressure is applied. This forces the center section, which contains the vibrator, against the top of the pipe. The combination of lift pressure and vibration will raise the pipe.
● Some of the lifting power comes from the centrifugal force of the vibrator. The rubber isolator pads at the ends of the machine and the air suspension of the lift mechanism prevent this vibration energy from t transferring down-ward.
● Intense high-frequency vibration allows the surrounding granular bedding material to flow from above the pipe to underneath, as the pipe is lifted.
● Sags of any length can be removed by moving the machine in increments and lifting along the length of the sag. Deeper sags will require multiple passes.
● With most bedding materials, it will likely be necessary for the material to be wet to be able to flow underneath the pipe.
