Clean&Fast solution for urban trenching

Cleanfast is a versatile machine of the Marais range that assures high productivity, high accuracy, limited disturbance to residents and quick restoration of the road. It’s a performant trencher for a cost efficient, clean and fast deployment of fiber optic and electric networks in urban and motorway environments. It’s a very usable road vehicle equipped with an axially driven up to 600 mm deep powerful trenching wheel able to simultaneously vacuum out and collect the excavated material, trenching in curves and sidewalks in different soil types (concrete, asphalt, rock). Cleanfast assures a clean and dust-free job site, a reduced amount of excavated material produced with adapted narrow tools and no material or dust thrown out during earth work; it provides complete filtration of rejected air.
