SAG Correction System (Patented)
Remove sags or low spots in PVC sewer lines from inside the pipe
How the SAG Correction System Works
The three sections of the sag remover are assembled inside a manhole. Two air hoses are connected. One to supply a pneumatic powered vibrator and one to power the lift mechanism.
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 prevents this vibration energy from transferring downward.
