Slurry wall cutter
LSC 8-20

Like a hot knife through butter

The innovative slurry wall cutter from Liebherr is used when particularly large trench depths are required and the subsoil is extremely hard. Unlike a grab, the diaphragm wall cutter works continuously during excavation. The existing subsoil is loosened and crushed by rotating cutter wheels.

Torque: 147 kNm

Bite lengths

2800/3200 mm

Slurry wall thickness

800-2000 mm

Max. working depths

150 m

The one-stop solution

The Liebherr slurry wall cutter package consists of the new LSC 8-20 hydromill trench cutter, the proven HS 8130.1 duty cycle crawler crane, the DS 150 hose drum system and a corresponding separation plant. Nevertheless, the HS 8130.1 maintains its multifunctionality and can also be fitted with slurry wall grabs, casing oscillators and tamper weights. This combination makes the package especially suitable for deployment in urban areas and has been optimized to enable quick and precise work.

Separation plant SP 600 C

  • Modular design with a high level of flexibility and best adaption to changing requirements
  • Extended walkways designed for easy access to all components
  • Long lasting, robust design based on more than 50 years experience in slurry treatment
  • Powerful integrated transfer pump with maximum capacity of 450 m³/h

Hose drum system DS 150

  • The system is designed for a maximum working depth of 150 m. It can also be equipped for reduced working depths providing a huge advantage for transport and assembly.
  • An additional diesel tank (500 l) in the hose drum carrier frame of the duty cycle crawler crane increases the total volume to 1270 l and enables the longest possible self-sufficient operation.

Functionality

Rock up to 120 MPa

  • Each cutter wheel is driven with 147 kNm and is designed for even the toughest of tasks.
  • Thanks to the quick installation system the cutter wheels can be easily exchanged.
All cutting wheels

Everything under control

  • The slurry wall cutter is fitted with a hydraulic turning device, which enables the continuous alignment of the slurry wall cutter in the trench. This means all possible working positions are 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's cab.

Verticality assistant

The assistance system is fully integrated for monitoring and logging the cutting process. Cutting reports for complete documentation, traceability and transparency at the construction site can be created at the push of a button.

Modularity

Standard

The Liebherr diaphragm wall cutter has a modular design so that customers can customise the setup to meet their individual requirements and technical challenges.

Low head

For construction sites with limited height, the modular milling frame can be shortened by four metres.
