LSC 8-18 Slurry wall cutter

The slurry wall cutter is modularly designed and has a robust base body. As the names of the slurry wall cutters LSC 8-18 C and L imply, slurry walls with thicknesses between 800 and 1800 mm can be installed. The term “C” (compact) stands for the compact version, while the base body of the “L” (large) version is 4 m longer – as an advantage for slurry walls with large dimensions. Bites with lengths of 2800 or 3200 mm and maximum depths of 110 m can be excavated with the slurry wall cutter. Liebherr offers the slurry wall cutter, the HS 8130.1 as carrier machine and the desanding unit as a complete package.
Wall thickness 800 - 1,800 mm
Bite lengths 2,800 - 3,200 mm
Weight version L (large) 33.0 - 46.0 t

Features

Cutter wheels

Cutter wheels

Thanks to the quick installation system the cutter wheels can be easily exchanged. Each cutter wheel is driven with 110 kNm and is designed for even the toughest of tasks.

Turning device

Turning device

The slurry wall cutter is fitted with a hydraulic turning device, which enables the continuous alignment of the slurry wall cutter in the trench.

Steering flaps

Steering flaps

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's cab.

Hose drum system DS 110 T

Hose drum system DS 110 T

Due to the large diameters of the hoses in the hose drum system DS 110 T, high efficiency can be achieved in cutting application.

Additional tank

Additional tank

An additional diesel tank (500 liter) in the hose drum carrier frame of the duty cycle crawler crane enables the longest possible self-sufficient operation.

Proven carrier machine

Proven carrier machine

The HS 8130.1 is designed as carrier. Its high performance winch handles the heavy weight of the slurry wall cutter.
