FTWB tunnel washing brush: Intelligent automation for maximum tunnel cleanliness
Efficiency at the touch of a button: The FTWB tunnel washing brush from FIEDLER is the technological answer to the complex cleaning requirements in tunnel systems and underpasses. Designed for attachment to equipment carriers or lorries, this system combines robust mechanics with state-of-the-art sensor technology to maintain infrastructure safely and preserve its value.
Precision through intelligent sensor technology: Your advantages at a glance
Automatic radius detection: Thanks to integrated sensors, the FTWB detects the tunnel radius in real time. The predefined distance to the wall is maintained fully automatically, which relieves the driver and guarantees a consistent cleaning result.
Smart tilt management: A high-precision tilt sensor independently detects the area to be cleaned. Whether tunnel wall, footpath or ceiling lights – the brush intelligently adapts its positioning to the respective geometry.
Multifunctional use: Beyond classic tunnel maintenance, the FTWB is a specialist for large-area cleaning of wall surfaces and traffic signs.
Maximum compatibility: Flexible mounting on various carrier vehicles makes the FTWB the ideal solution for motorway maintenance departments and municipal service providers.
Put your trust in an automated system solution that saves time, increases safety and impresses with its durability. With the FTWB tunnel washing brush, you are setting new standards in modern traffic route cleaning.
