2024 Liebherr Slurry wall grab HSG 5-18 C/L

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. When working in difficult ground conditions, the dead weight of the grab can be increased with an additional weight of 7 t. Bites with lengths of 2500-3600 mm and maximum depths of 90 m can be excavated with the grab.

Features may include:

• The modular design of the grab promises a high level of flexibility and enables the optimum adaptation to jobsite requirements.

• The grab convinces with its robust design and high closing force. These properties provide a decisive advantage especially in hard soils.

• Thanks to the synchronisation of the hoisting winches high grab weights are viable and the lifting capacity of the duty c

• The robust design of the grab and the synchronized free-fall winches allow for light chiselling as accustomed with mechanical grabs.

• 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.

• Opening and closing of the grab jaws is synchronised via push rods. This mechanism is reliable and easy to maintain. The piston rods of the hydraulic cylinders are protected inside the grab body.
