The ZRM 350 requires no skeleton track for ballast bed cleaning. In the construction gap, the machine is propelled by crawler tracks.
The ZRM 350 produces an accurate cut of the formation along the entire length of the work site thanks to continuous forward motion and automatic laser-assisted guidance of the excavating chain (alternatively with reference wire guidance). That is one of the greatest advantages of this system compared to conventional methods using wheeled loaders. The crawler tracks never come into contact with the formation. Moreover, the ZRM 350 can also perform on-track ballast cleaning.
On/off-track material conveyor and hopper units complete the ZRM 350 and make it an efficient ballast cleaning system for areas without tracks. They assure evacuation of spoil and supply of new ballast.
