The new Casagrande KHD system is dedicated to the construction of diaphragm walls. The compact design and rotation system make it ideal for narrow spaces and to make diaphragm walls with different alignments. Modularity of the boom makes it possible to pass and build diaphragm walls even below existing structures. The heavy weight, clamping force of the hydraulic grab and quick free-fall winches allow you to successfully build diaphragm walls even on difficult ground.
