Rebuilt 2011 year-Plasser RM74




  
  The RM 74 ballast cleaning machine is a well proven, high performance Ballast Cleaning machine that gives top quality results in the toughest operating conditions. The high powered cutting chain and specially designed screening unit ensures high working speeds, even in heavily, encrusted ballast. The RM 74's 80 km/h travel speed and short set up and knock down times allow maximum utilization of available track time.
  A special model of the RM 74 ballast cleaning machine, proven in operation for many years. The very low axle loads (< 10 t). The additional weight-bearing axles of the RM 74 S ensure a uniform distribution of the weight to keep within the threshold values. During ballast cleaning the load on one of these axles is reduced to achieve a gentle bending line of the raised track.
  The basic concept of the RM 74 from the production range of Plasser & Theurer provides a ballast cleaning machine that is specially suited for operation on normal gauge 1435 mm and narrow gauge 1000 mm, utilising the proven components of the Plasser & Theurer ballast cleaning machines.
  The work units such as the excavating unit, vibrating screening unit, track lifting and slewing unit, as well as the conveyor systems, power units and hydraulic plants are based on the wealth of experience gained in over 40 years by the design engineers at Plasser & Theurer. The RM series ballast cleaning machines have demonstrated all over the world their perfect functionality, lasting operational safety and the superior quality of the work they perform.

  ADDITIONAL OPTIONS against assitonal payment at client's desire:
+REM Georadar Measurements - RGM : Automated system for georadar (ground-penetrating radar) roadbed inspection REM GEOSCANNER is intended to provide the following solutions:
  - determining thickness and lithologic structure of the ballast bed discriminating the fouled subgrade layer and increased moisture areas;
  - localizing the upper boundary of roadbed soils and their lithologic structure;
  - discriminating low coherence areas in the roadbed featured by reduced density and increased moisture;
  - revealing foreign objects in the roadbed and ballast bed, viz., cables, buried track superstructure components (crossties, rails), large stones, etc.
  - localizing engineering facilities;
  - localizing areas with laid geotextile or expanded polystyrene;
  - inspection of quality of the accomplished track overhaul.
  The objective of this method of investigation is to determine the pollution within the ballast bed and the mixture of ballast with the subsoil. It is also possible to locate water traps. The qualitative measurement of the water content in the subsoil enables the existing drainage quality to be assessed. By comparing the condition before and after the rehabilitation, it was possible to make a quality assessment of the formation rehabilitation work performed.

  Technology
  The REM Georadar Measurements - RGM is state of the art for GPR systems. It is based on more than 20 years of working experience with GPR and it is the product of continuous development and adaptation to the specific requirements of our international railway customers.
  - Survey of tracks of any length or even of the entire railway network.
  - High speed survey of 900 track kilometres per run.
  - 2,000 scans per second.
  - Each channel is controlled separately, allowing even speeds of more than 300 kph.
  - Three or even more longitudinal profiles provide track cross section at any position.
  - Measurement only between sleepers to avoid disturbances.
  - Scan distance between 2 cm and 60 cm for coping with all customer requirements.
  - Antennae frequencies between 100 MHz and 900 MHz for high resolution in all depths.
  - System-embedded positioning radar for accurate allocation of all measuring data along the entire track. Accuracy better than 0.5 m.
  - System-integrated DGPS for reception of world wide satellite systems GPS and GLONASS. Correction data for GPS via GSM or EGNOS for an accuracy better than 0.3 m.
  - Displaying of survey track and all constructions in Google Earth.
  - System-integrated Video-camera for continuous view of survey track.
  - System-specific Viewer-programme for display of the GPR results related to the geotechnical conditions of the track, including Google-Earth-view and Video-camera-pictures.


  The RGM survey provides continuous details of track conditions. Railway engineers obtain important information about:
  - Thickness of track bed and sub-ballast layer.
  - Sections with clean or fouled ballast.
  - Drainage problems in ballast bed and undertrack.
  - Mapping of load-bearing problems (settlements, ballast pockets).
  - Anomalies along the track.

  RGM - Radargram with longitudinal profile of track section
  The picture shows a track section between km 11.100 and km 11.700.
  In that section the ballast has been renewed to a depth of 0.3 m. Below, there is fouled ballast (dark grey layer). Ballast settlements indicate insufficient bearing capacity of the sandy formation. Below the sandy layer, a drilling at km 11.450 is showing peat and clay.


  The picture shows a track section between km 1.300 and km 1.900 (see horizontal axis). The vertical axes represent both depth in m related to top of sleepers and travel time of the waves in nanoseconds.
  
In that section the ballast has been renewed to a depth of 0.5 m (pale grey layer). Below, there is fouled ballast (dark grey layer). Ballast settlements can be seen between km 1.460 and 1.570. This is an indication for insufficient bearing capacity of the sandy subgrade (yellow layer). Below the sandy formation there is clay to be found. Between km 1.600 and km 1.900 the clay layer is almost adjacent to the ballast bed. In this section, a well working drainage is important. Otherwise water will remain inside the track, leading to eventual stability problems of the track.
  The picture shows crossings at km 1.370 and km 1.870. Drillings have been carried out at km 1.550 and km 1.740. In both cases ground water has been found in a depth of 1.2 m.


  Quality control of track construction
  
Track construction is always very cost-intensive. That's why at least the result should add up. Our quality control is continuous and exact. And we provide information about:
  - Quality of new ballast (cleanliness).
  - Thickness of track bed and sub-ballast layer.
  - Efficiency of track drainage.
  - Evenness of ballast-bed bottom or sub-ballast layer.
  - Track cross-section.

  Examples cables, pipes, objects

  Example for a cable crossing at km 14.094 in the formation in a depth of 1.20 meters.

  Example for a cable crossing at km 13.999,5 at the ballast base in a depth of 0.42 meters.

  Cables, pipes and objects in various depths between 0.16 m and 1.36 m along a range of about 30 meters.
