Track measurement

The trolley measures track and turnout geometry as well as 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.   

Measurement results such as values of width, cant, horizontal and vertical irregularities, covered distances and GPS positions are recorded in the device memory on a real-time basis. During turnout measurements, operator activates the turnout mode enabling the recording of measurement results related to groove widths and check-rail gauges. All measured parameters are recorded using a measurement increment of 30 mm. In addition, at each characteristic point the operator can stop the trolley and save values of all parameters required in accordance with a previously prepared set of characteristic points.

The trolley can be easily and quickly (ca. 26 kg in weight) removed from a track to allow the safe passage of trains. Measurements can be instantly resumed without calibration or zeroing. 

The TEC 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 supplied with the entire list of sets of characteristic points required by Internal Instruction Id-4.

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 turnout module of the GeoTEC System software can be used to modify and create new sets of characteristic points, including information about measured parameters, nominal values and allowed tolerances in relation to various types of turnouts.
