Formation rehabilitation machine with integrated ballast recycling RPM-RS-900
Track-laying – Recycling, formation rehabilitation, ballast cleaning
The RPM-RS-900 was designed for formation remediation and for processing track ballast, and is the longest machine in SPITZKE’s technology park. Its strength lies in its versatility. Formation rehabilitation, ballast cleaning and ballast recycling are all achieved within a single machine complex. The ballast is excavated, recycled, re-laid, compacted and stabilised. The soil is excavated, the new FPL material laid, profiled and compacted. All operations are rail-bound, without blocking the adjacent track. This enables short track possessions and high track availability.
Functional Characteristics
RECYCLING WORK
- Excavation, recycling and transport of old ballast
- Laying of recycled or cleaned ballast
- Removal of soil and transport of excavated soil on MFS wagons or optionally on wagons next to the working track
- Ballast residues are transported away on MFS wagons or optionally on wagons or trucks next to the working track
- Two free-swinging vibrating screens with double pre-separation (scalping)
- Metered feed, flexible laying height and width, uniform compaction of FPL material, parallel laying of geosynthetics and/or geogrids
- Metered feed, laying, and uniform compaction and stabilisation of new ballast
FPL RECYCLING WORK
- Simultaneous excavation of the ballast and soil
- Excavated soil is transported away on MFS wagons or optionally on wagons or trucks next to the working track
- Crushing and recycling of the ballast material
- Controlled mixing of the recycling material with the new added FPL material
- Controlled placement and compaction of the material as a formation protection layer
BALLAST CLEANING WORK
- Excavating the ballast
- Two free-swinging vibrating screens with double pre-separation (scalping)
- Flexible ballasting using a swivelling conveyor belt with level control
- The ballast formation can be compacted by means of compactors
- New ballast can be laid in parallel using trailing MFS units
- Integrated, continuously-working tamping machine with satellite control, 16 tampers and front compaction
- Trailing, integrated sweeping shaft
- Cleaning power up to 900 m³/h
- Complete ballast renewal (complete ballast replacement) in a single operation (full excavation)
- Ballast recycling and placement of recycled ballast
- Laying of geosynthetics and/or geogrids
