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 transfering downward.
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.
If there is no ground water present, it may be necessary add water to the bedding material.
We recommend applying water with something similar to the jet pipe shown. With water flowing, the pipe should be able to be pushed into the backfill by hand.
If covered with pavement, a core drill like those used to take asphalt test cores, can be used to access the jet pipe.
The 8 inch pipe adapter bolts to the center section of the sag machine. It allows the machine to lift above parallel when removing sags longer than the span of the machine.
It is replaced with other pipe adapters for larger diameter pipes.
Length: 104 inches overall assembled.
Lifting span: 96 inches center to center of the lifting pads.
Weight: 65 to 70 lb. for end sections, 93 lb. for center section, aprox 230 lb. total.
Air consumption: 70 CFM @ 80 - 100 PSI.
