Why APPI: Over a period of time, corrosion can lead to a drainpipe collapsing and causing catastrophic road failure. The Strong Company, a leading manufacturer in the specialty cement industry, has developed a revolutionary new system that addresses this common problem without the need for road closures and the cost of excavating and replacing the pipe. Strong’s “Storm Seal” application technique creates a cement lining by spin-casting material to repair the pipe. In addition, our Columbia W2000 AC winch with an AutoAdvance Line Spooler ensures proper spooling regardless of the approach angle of the line to the pipe opening.
This AC repair winch is powered by a 3/4 horsepower motor using a 115-volt electric motor. A manual freespool lever allows the operator to disconnect the drum from the geartrain and pull the wire to the starting position. A NEMA 4X rated handheld pendant with momentary contacts for forward and reverse. A speed potentiometer allows the operator to vary the pulling speed, which determines the thickness of the coating. The AC winch is mounted on the bed of a service truck, and the line is rigged to the drainpipe opening using change of direction sheaves.
