Tron OEM Cutting Wheels

Cutter progress is heavily dependent on the soil conditions, so the selection of the most suitable type of Cutting Wheels is essential.

Tron OEM Cutting Wheels are available in a variety of sizes to enable cutting of different widths of trenches.

Additionally the suction box and the cutter frame have to be adapted to the required trench width.

• Standard cutter wheel

Standard Cutting Wheels are primarily used in mixed soils. They are equipped with a large number of differently shaped tungsten carbide-tipped teeth. The available selection ranges from aggressive cutter teeth through to impact teeth. Long teeth holders enable easy replacement. Reamer plates, attached to the suction box, remove any spoil between the tooth holders, particularly in cohesive soils.

Round shank chisel cutter wheel

Primarily designed for cutting cemented sands, conglomerates, cobbles and weathered rock, these Cutting Wheels are equipped with special round shank chisels.

The teeth arrangement on the wheel ensures cutting of the whole cross-section area to enable constant cutting progress even in challenging geotechnical conditions.

Hybrid cutter wheel

The hybrid cutter wheel is equipped with a combination of round shank chisels and flat teeth in a regular pattern. Its main use is cutting through non-cohesive or cohesive overburden soil followed by socketing into hard soil or rock.

FAQ:How Does a Hydromill Work

Since its introduction in 1980s, the Hydromill diaphragm walling technology has developed rapidly. As a result of the wealth of experience accumulated over the following decades, the challenge being faced today is cutting trenches into extremely hard rock and achieving ever-increasing depths. Through project-specific adaptations of the Cutting Wheels, high excavation outputs can frequently be achieved. The open trench which is stabilized and supported by a thixotropic slurry is excavated in a continuous operation.

The slurry charged with spoil material is conveyed to the surface by a mud pump, which is mounted inside the cutter frame. The charged slurry then passes through a desanding plant. Here, the solid particles are separated out from the support slurry. The cleaned slurry is then pumped back into the slurry circulation system for reuse as support slurry in the trench. With the cutter technique depths of more than 100 m can be achieved.
