Track Geometry Measurement Instrument

A track inspection trolley is a device used for detecting the geometric condition of railway tracks.

It is primarily used for accurately measuring the track gauge. Through precise measuring devices, it can obtain the distance value between the two rails, ensuring the gauge complies with railway operation standards. It is also highly accurate in measuring track leveling, detecting whether the top surfaces of the left and right rails are at the same height. Excessive level deviation may cause train body sway during operation, and the track inspection trolley can effectively prevent this situation.

Regarding track vertical alignment, the trolley can measure the smoothness of the rail top surface along the longitudinal direction of the track. For instance, at locations where the track has sunk or bulged, it can accurately identify the extent of change. Additionally, it can measure the track alignment to determine whether there are issues such as twisting or bending that do not meet requirements.

The track inspection trolley generally features convenient mobility devices, making it easy to push along the tracks, and its operation is relatively simple. Its measurement system integrates high-precision sensors, enabling rapid data collection and transmission to supporting software systems. In the software, data can be displayed in intuitive formats such as charts, facilitating analysis by staff and providing a reliable basis for track maintenance and adjustments. At the same time, it possesses a certain level of environmental adaptability, allowing it to operate normally under various weather and railway conditions.
