Trolley-type Railway Structure Gauge Measuring Instrument

FTXJ-C Railway Structure Gauge Measuring Instrument (Trolley Type)

FTXJ-C Railway Structure Gauge Measuring Instrument is a railway structure gauge measurement device developed by Beijing Feituo Xinda Laser Technology Co., Ltd. This instrument complies with the system composed of laser ranging, grating angle measurement, gauge module, level measurement module, and mileage module. It is capable of measuring rail gauge, superelevation, vertical clearance dimensions, and horizontal clearance dimensions.

Product Design Standards

The product complies with the following standards:

JJG (Railway) 197-2022 "Railway Structure Gauge Measuring Device"

TB/T 3308-2013 "Measurement and Data Format of Actual Railway Structure Gauge"

Product Structure

The measuring instrument is an all-in-one device, with the main measurement unit and the measurement frame connected as one. The main unit functions include: laser measurement and vertical angle measurement; the measurement frame is a horizontal bar placed between the rails, primarily serving to support the main measurement unit, measure rail gauge, and measure horizontal tilt angles.
