Method for performing overhead crane rail alignment surveys
Field measurements Method for conducting an overhead crane runway system survey uses FMI personnel to accurately place survey sighting targets, e.g., prisms, that are visible to survey personnel on the ground. XYZ data is there collected and a rail alignment profile, a rail elevation profile, a rail span profile, and/or a crane skew profile may be generated. The data and profiles generated can be reviewed to ascertain whether the overhead rails conform to alignment specifications. Further, crane skew data may be reviewed to determine whether the crane itself may be misaligned.
