The URM 700 is a universal cleaning machine for turnouts and tracks. The guide bar can be inserted and removed without dismantling the turnout or excavating an entry hole for the excavating chain. Due to the fast and independent installation and removal of the excavating guide bar, the URM 700 can also work cost-effectively on short sections of track (spot cleaning).
The machine system comprises of three sections and consists of: the drive and excavating machine, linked by a connecting rod, the screening car and the optional MFS unit for collecting and storing the cleaned ballast at start of worksite.
The URM 700 system can perform all standard working methods of on-track ballast cleaning, particularly ballast cleaning in turnouts and plain track. In addition to this, it is able to clean only the ballast shoulders. The supply of new ballast is an integral feature of the design in all variations and it is possible to perform a full exchange of the ballast.
