  • Method and apparatus for performing overhead crane rail alignment surveys
    Patent number: 7428781
    Abstract: A method and apparatus for conducting an overhead crane runway system survey uses a survey apparatus that is alternately pushed or pulled by an overhead crane. The survey apparatus, having a wheeled carriage, includes 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 may 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.
