Portable Railway Structure Gauge Measuring Instrument

FTXJ-3 Railway Structure Gauge Measuring Instrument (Portable)



The FTXJ-3 Railway Structure Gauge Measuring Instrument is a railway structure gauge measurement device developed by Beijing Feituo Xinda Laser Technology Co., Ltd. The instrument complies with the system, which consists of laser ranging, grating angle measurement, and track gauge and level measurement modules. It is capable of measuring the track gauge, superelevation, vertical clearance dimensions, and horizontal clearance dimensions of the rails.


Product Design Standards
The product complies with the following standards:
JJG (Railway) 197-2022 "Railway Structure Gauge Measuring Device"
TB/T 3308-2013 "Actual Railway Structure Gauge Measurement and Data Format"

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 track gauge, and measure horizontal tilt angles.
