Power. Control. Precision.
The LSC 8-20 is Liebherr’s latest slurry wall cutter – a world-first in specialist foundation engineering. Designed for extreme conditions: tight urban spaces, deep excavation pits, and demanding ground environments. It’s a machine that brings together massive force and absolute precision – where every control action needs to be spot-on.
Consulteer supported the project from day one as a design partner – with a clear goal: to develop a control solution that truly supports the operator’s daily work. Intuitive, durable, and built for tough on-site conditions.
Our contribution combined three core disciplines:
UX Research on the job site – including shadowings, interviews, and rapid prototyping
Industrial Design for a new, ergonomic control panel with clear tactile logic
User Interface Design that visualizes complex machine states in a clear, structured way
Built for Extremes
When 60 tons of steel are working deep underground, every decision counts. Operating a machine like the LSC 8-20 means monitoring multiple pressure systems, gearboxes, sensors, and target values – under pressure, amid vibration, heat, or cold.
The previous control logic worked, but it was overloaded, visually cluttered, and outdated in its interaction design.
What was needed: a new interface, built around real-world site conditions – understandable, safe, and efficient.
Developed on site
Our UX designers worked where the machine does – on site. Through expert interviews, job shadowing, rapid prototyping, and ergonomic testing, we immersed ourselves in real workflows.
The result: a concept shaped not in the studio, but through hands-on experience with the people who use it daily.
One System. One Logic.
What began as a panel redesign turned into a complete overhaul of the human-machine interface. Together with Liebherr’s development teams, we created a seamless control concept that integrates both analog and digital layers.
A restructured physical panel with tactile feedback and intuitive grouping
A digital interface that simplifies and prioritizes key system data – from oil pressure to cable twist
A visual language designed for quick understanding in challenging on-site conditions
Built for Operators
The new control logic of the LSC 8-20 improves orientation, reduces errors, and shortens onboarding – noticeable in everyday use.
Key benefits:
Clear visual structure for fast orientation
Intuitive handling that shortens response times
Rugged design built for real-world environments
The result is a system that makes complex processes manageable – and delivers where it matters most: on the construction site.
