Liebherr LSC 8-18 slurry wall cutter

Liebherr has introduced a new package solution for slurry wall applications - consisting of an LSC 8-18 slurry wall cutter, HS 8130.1 duty-cycle crawler crane and a desanding unit - especially suitable for deployment in urban areas.

The LSC 8-18 can install slurry walls with thicknesses between 800 and 1,800 mm. The unit has a total height of 12 m and a low centre of gravity, providing better vertical positioning and excellent control. Bites with lengths of 2,800-3,200 mm and maximum depths of 110 m can be excavated with this slurry wall cutter.

Thanks to their quick installation system, the cutter wheels can be easily exchanged. Each cutter wheel is driven with 110 kNm, designed for demanding tasks. Due to the large diameters of the hoses in the 110 T hose drum system, high efficiency can be achieved in cutting application.

The HS 8130.1 crawler crane (as the carrier machine) maintains its multifunctionality and can also be used in grab operation or for lifting jobs. All control elements of the LSC 8-18 are fully integrated in the handling concept. Thus, a quick change between different applications is possible.

The LSC 8-18 is fitted with a hydraulic turning device, which enables the continuous alignment of the unit in the trench. As a result, all possible working positions can be covered. Twelve independently controllable steering flaps correct the cutting direction, and the actual position of the flaps is displayed in real time on the monitor in the operator cab.

The central lubrication system of the LSC 8-18 allows for quick and simple maintenance. An additional 500-l diesel tank in the hose drum carrier frame of the HS 8130.1 increases the total volume to 1,270 l and enables the longest possible self-sufficient operation.

The HS 8130.1 is also equipped with a new cabin design for increased operator comfort. It features a modern air-conditioning system with improved airflow, an optimised field of vision and reduced noise protection, as well as an orthopaedic operator’s seat with integrated heating and cooling.

Liebherr offers the LSC 8-18 slurry wall cutter, the HS 8130.1 as carrier machine and the desanding unit as a complete package. It is available worldwide.
