DHG Hydraulic Grabs

DHG is a diaphragm wall grab which is rope suspended and operated hydraulically. the 80 - 120 ton closing force and 6 - 10 second shovel opening / closing time are activated by a cylinder which is installed vertically inside of base body. High closing forces in combination with the posibility of multiple grabbing at the trench bottom result in high excavation rates even in dense and very hard soil strata.
