The hydraulic slurry wall grab is modularly designed and has an extremely robust base body. As the names of the grabs imply, HSG 5-18, slurry walls with thicknesses between 500 and 1800 mm can be installed, depending on the composition. The base body of the “L” (large) version is 2.5 m longer. The resulting total height of the grab at 9.5 m, as well as the high weight with low centre of gravity provide for even better vertical positioning and are especially advantageous when installing larger dimensioned slurry walls.

    Chiselling
    The robust design of the grab and the synchronized free-fall winches allow for light chiselling as accustomed with mechanical grabs.
    Hydraulic rotating device
    Alignment of the grab in all directions as well as quick and operator-friendly 180° rotation after each grab cycle thanks to a hydraulic rotating device. The assistance of an employee on the ground is no longer required.
