GF2060 digital railway wheel parameters caliper(usually called flange caliper) used to measure the flange thickness, flange height and QR value parameters of subway vehicle wheel . The flange checker adopts a digital display reading design, which has the characteristics of novel design, easy operation, intuitive reading and accurate measurement.
The flange caliper mainly consists of a magnetic positioning surface, a main scale, a flange thickness gauge, a rim height gauge, a QR value gauge, an adjustable probe, a tread positioning probe, and a calibration block.
| Model | Measuring range (mm) | resolution (mm) | Indication error (mm) |
| GF2060 | Flange thickness 20~33 | 0.01 | ≤±0.1 |
| Flange height 0~36 | |||
| QR value 0~13 |
