Rotary chain cutter
Rotary chain cutter – Operational experience
Rotary chain cutters are composed of a guide sled with three or more skids and a rotating head with steel chains. The rotating head can either be driven hydraulically using high pressure water or via an electric motor. The device installed on the guide sled is pulled through the section using a cable winch. The skids ensure the stability of the rotary chain cutter during its operation in the sewer. The steel chains installed on the rotating head cut off protruding roots and incrustations.
