Since many municipal and industrial settling ponds are lined with an impermeable membrane rather than concrete, Crisafulli engineered a pond liner protection system that prevents the cutterhead from cutting or damaging the pond liner. The Crisafulli Pond Liner Protection System (“PLPS”) can be attached to any Crisafulli cutterhead. Shown below first with a vacuum “cutterhead” and then mounted on the Cobra Cutterhead. Notice in the lower photo the Floating Discharge Pipe running off behind the FLUMP. Comprised of two small wheels mounted on an axle, the PLPS raises the cutterhead a few inches above the pond liner and enables the cutterhead to roll along the pond bottom.
