Track measurement

TRACKSCAN PROFILE

The trolley measures track geometry as well as railway and tramway rail head profiles and records results of track condition visual inspections. The trolley is easy to use and has a modular design enabling its transport by one person and fixing on a track in less than 5 minutes. In addition, the possibility of using the trolley on any track gauge significantly increases work productivity.

The trolley can be easily and quickly (weight ca. 30 kg) removed from a track to allow the safe passage of trains. Measurements can be instantly resumed without calibration or zeroing.

The TSP trolley meets the requirements of the EN 13848-4 standard. Measurement results generated by the trolley are consistent with the requirements of the Polish Railway Lines (PKP PLK).

The trolley is provided with a colourful backlit display and a comfortable keyboard (typical of other GRAW products). Measurement results and information about exceedings of allowed values are perfectly visible even at night. Dedicated keys of typical defects facilitate the recording and annotation of cracks in welds or rails, missing bolts, sleepers requiring replacement, etc.

The trolley control panel can be removed, facilitating the overview of results after the completion of measurements. The transfer of data to a PC is performed via a USB Pendrive.

The trolley is supplied with the GeoTEC System software (for PCs) enabling, among other things, the graphic presentation and comparison of measurement results as well as the printing of measurement reports or calculating typical track quality factors. Measurement results are also available in the tabular form containing track defect locations. Measurement data can be exported in MS Word, MS Excel and PDF formats.

In addition, the software enables the saving of measured profiles in the DXF format, comparing measured profiles with model profiles, automatic sizing and printing of rail profile-related reports.
