DHG Hydraulic Grabs


DHG is a rope-suspended, hydraulically operated diaphragm wall grab. The closing forces are activated by a vertically installed cylinder via crowd rods. High closing forces in combination with the possibility of multiple grabbing at the trench bottom result in high excavation rates even in dense and very hard soil strata.
