Washing tunnels around the world: Unimog equipped with a Mulag MFK 500-T.

What do Japan and Mexico have in common? A multitude of road tunnels in big cities and on out-of-town trunk roads. They are subjected to immense strain by the vast quantities of traffic flowing through them and the partially tropical climate of both countries. Exhaust emissions, dust, fauna and flora all create visible soiling which, in some cases, can even become a safety hazard.

This is why it’s particularly important that they are cleaned on a regular basis, so as to prevent cars and motorbikes from being hindered by dirt or poor visibility. Unimog ExpertPartner Mulag has come up with a special implement solution for the job: the MFK 500-T tunnel washer. In Japan and Mexico, this Unimog combination has already proven its worth.

Innovative equipment for rapid and thorough cleaning.

The newly developed MFK 500-T tunnel washer features some additional, innovative equipment and is thus an ideal body option for Unimog implement carriers used in professional cleaning applications. Among the features are a convenient washer fluid dosage system and a powerful high-pressure cleaning system. As standard, the telescopic boom allows for a reach of up to 7.4 m, thus making cleaning at this height especially easy. And, thanks to a large lateral adjustment of 1800 mm and a sweep range of 190 degrees, the Special Truck can flexibly adapt itself to the conditions of the respective tunnel.

The transport position of the boom in front of the vehicle makes for convenient, simple manoeuvring into and out of parking spaces – even in the case of tight tunnel diameters. The Unimog with MFK 500-T is always ready for its special tasks: thanks to the hydraulic movement system on the washing brushes, the tunnel washer can be made operationally ready in a matter of seconds.
