Hydraulic grab for diaphragm wall
The HGV is a hydraulic rope suspended grab designed to carry out the necessary excavation, either of rectangular or semicircular section, for the subsequent preparation of diaphragm walls in terrains of variable consistency.
Efficient penetration is achived by a combination of the grab weight and the high closing force and synchronized closure of the jaws. For particularly difficult soil conditions, the HGV hydraulic diaphragm wall grab can be fitted with a chisel.
