The Locomotive Foldable Track Base Buffer Height Gauge is used to measure the height of the horizontal center line of the hook from the top surface of the rail during the factory, section and station repair of railway locomotives, vehicles and EMUs. No conversion is required, and the value of the horizontal center line of the hook from the top surface of the rail is directly read.

The ruler has a reasonable structure design, is easy to carry, simple to use, easy to inspect and adjust, and the reading is intuitive, accurate and reliable.
