ADD-ON FOR TRACK

ADD-ON FOR TRACK

The trolley measures clearance and track geometry as well as records results of track condition visual inspections. The add-on provided with a laser range finder and mounted on the trolley enables measurements of structures and objects having sizes in excess of 10 mm, including, light signals, tunnels, platforms, intertrack spaces as well as the height of the contact wire, poles and other elements located within 7 metres away from the track axis. 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. Clearance measurements are performed by the operator aiming the laser beam at a selected point (after stopping the trolley). After a measurement, the trolley control panel display presents the position of a point being measured in relation to the track axis. Measurement results along with locations of related objects are saved in the device memory.

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 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 makes it possible to save clearance measurement results in the DXF format, compare objects with the track clearance, automatically identify points of collision and print reports concerning rail profiles.
