The center piece of the trench cutter systemconsists of a steel frame with two gearboxes attached at its base, which rotate in opposite direction about a horizontal axis.
Cutter wheels suitable for the prevailing ground conditions are mounted on the gearboxes. Due to the rotation of these cutter wheels, the soil materialbelow the cutter is continually loosened, broken down, mixed with the support slurry in the trench and conveyed towards the suction inlet of the mud pump.
