To install the crane span before installation, camber, level of metal structure of main girder bending, trolley rail height difference, gauge deviation, diagonal bridge survey.
Comparison between the measurement results with QY inclinometer and photoelectric bridge deflection gauge shows that QY inclinometer is reliable and has high precision.
对比结果表明利用倾角仪测量桥梁挠度的结果是可靠的,精度是有保证的。
