Diaphragm Wall

Diaphragm Wall

Casagrande started manufacturing equipment for diaphragm walls in 1963. Over the years, it has developed a complete range of machines in order to satisfy the contractor’s requirements.

Requests for a special machine to excavate efficiently in medium hard to soft soils led to the development of the KRC and grab type K combination. This equipment guarantees superior productivity and makes control of verticality easy in the excavation of diaphragm wall panels and barrettes. The KRC can get into tight corners; a turntable enables the Kelly and the grab to be rotated 45°or 180°, easy transportation without dismounting and quick assembly without service crane. Latest introduction is the hydraulic rope suspended grab system KG25.
