Rail bottom slope measuring instrument

FTDP-3 Rail Cant Measuring Instrument

I.Instrument Overview

The main contact part between the wheel tread and the rail top is a 1/20 slope. In order to ensure that the rail top bears the axial force, the rail should also have an inward inclination, which forms the rail cant. Setting the rail cant can concentrate the rail joint contact on the middle of the rail top, improve the lateral stability of the rail, reduce uneven wear of the rail head, and also help reduce plastic deformation of the rail head and extend its service life. Since 1965, the standard rail cant for straight sections of China's railways has been uniformly changed from the original 1/20 to 1/40.

IV. Operation Instructions

1. Fully charge the instrument before use. For charging, use the dedicated charger provided by the manufacturer and insert it into the charging port. When the indicator light on the charger changes from red to green, it means the charging is complete. One full charge can last for 8-10 hours, and the charging time takes 3-5 hours.

Note: Be sure to use the dedicated charger provided by the manufacturer.

2. When using, first turn on the instrument power switch, as shown in the figure above, attach the working surface of the instrument to the measuring point on the rail, and then you can read the measurement data. The normal reading range is -1:10 ~ +1:10 or -10° ~ +10°, and the instrument reading will flash if it exceeds the range.

3. Please put the instrument back into the dedicated box after use to avoid loss of accessories.

4. If you do not use it for a long time, charge the instrument regularly to avoid damaging the battery.

Note: Wipe the bottom of the rail clean before measuring to ensure the accuracy of the equipment measurement.
