Our SG series of hydraulic diaphragm wall grabs guarantee precision and verticality every time by utilizing LiuGong’s patented steering plates. Fast and efficient excavation is achieved with a variable grab which can handle up to 25 tonnes. LiuGong’s intelligent hydraulics ensure an extremely high and efficient closing force which allows more material to be moved with the minimum noise and vibration. As with all LiuGong machines, the SG series are tough machines which are comfortable and safe to operate, easy to maintain and built to last.
