Track Geometry Measuring Instrument

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

It is primarily used for accurately measuring the track gauge. Through precise measuring devices, it can accurately obtain the distance between the two rails, ensuring that the gauge complies with railway operation standards. It is also highly precise 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 example, at locations where the track has sunk or bulged, it can accurately identify the extent of the change. Additionally, it can measure the track's 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 track, 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 personnel and providing reliable basis for track maintenance and adjustments. At the same time, it also possesses a certain degree of environmental adaptability, allowing it to operate normally under various weather and railway conditions.
