Carriage for the rail scaloping wear indication

The field of application.

CarriageThe carriage is designed for the use at the road economy of mainline railways and the underground.

Registered rail irregularities and defects are the following (according to NTC/CP-2-93):
defects 40 and 49 are scalloping irregularities and riffle;
defects 46.3 are cols in the regions of welded joints;
defects 14 are axles;


The carriage can be used for the periodical monitoring and testing of longitudinal profile of the rail-wing head roll surface and for planning the lap work volume and the subsequent lap quality check.


Basic functions

- Getting the real time information on the nature of short continuous irregularities and on the path, traversed while moving with the binding to the track coordinate;
- Continuous visualization of the short irregularities parameters for each of the track ways in the form of functions of traversed path at the display of the computing unit;
- Accumulation of information at the magnetic medium and documentation it by printing;

Laser rail portable profilograph of PRP-1 type

The field of application.

Rail portable profilograph Rail Portable Profilograph of PRP-1 Type is a manual diagnostic devise for registering flaws of functional surface cross direction profile at the road economy of mainline railways and the underground.
PRP-1 enables to find the solution for the problem of the periodical monitoring and testing of rail longitudinal profile and for planning the work volume and the control of the quality of rail-grinding trains and rail-grinding equipment functioning.

Advantages of PRP-1

- Noncontact (optical) method of measurement of rail head profile (by using RF600 series) which enables to register sophisticated flaws at large scanning angle (laser sensor of RF600 series is used )
- The visual traceability of measured profile and standardized deterioration parameters on the graphical display of microprocessor system computing unit (SCU);
- Minimal time of measuring process and of placement/ displacement the scanning means on/off the rail procedure;
- Convenient interface SCU that lets input identification information on the measured profiles efficiently using the keyboard for the subsequent documentation;
- Recording up to 1000 profiles onto the magnetic medium SCU with possible visualization of any measured profile at field conditions;
- Metrological acceptance of the means by normative parameters being measured at special metrological rack;
- High level of means proofness from external actions (IP65);
- Special PC program that enables to record the information on the measured profiles with the consequent processing, comprising:
          - Overlapping of any two profiles (including the sample one and the repaired one)
          - Printing out the information;
          - Characterization of any profiles point and their areas;
          - Output of identification information on measured profiles;
          - Possibility to create repair profiles data bank etc.


Controlled parameters:

- Vertical wear of rail head (hB);
- Lateral wear of rail head (hb), measured at 13 mm down from the top of its head;
- Lateral wear of rail head(hbL45), measured at 45 degree angle with respect to rail symmetry axis at the point, going through the middle of lateral operating fillet;
- Mentioned rail head wear, defined as vertical one + half of lateral one, in details: hpr = hB + 0,5hb or hpr = hB + 0,5hbL45.
