Liebherr Releases New Package for Slurry Wall Applications

Recently presented at Intermat in Paris and already successfully carrying out work for the metro expansion in Milan, Liebherr’s new package for slurry wall applications is comprised of a duty cycle crawler crane and hydraulic grab.

The hydraulic slurry wall grab is modularly designed and has an extremely robust base body. As the names imply, HSG 5-18 C and HSG 5-18 L can install slurry walls with thicknesses between 500 and 1,800 mm, depending on the composition. The “C” stands for the compact standard design, while the base body of the “L” version is 2.5 m longer. The resulting total height of the grab (9.5 m) and the high weight with low center of gravity provide for even better vertical positioning and are especially advantageous when installing larger dimension slurry walls. When working in difficult ground conditions, the execution can be improved through increasing the dead weight of the grab with an additional weight of 7 t.
