Abstract
A method and system for conducting a non-contact survey of an overhead crane runway system using a survey apparatus that is alternately located in the crane bay or on a crane bridge girder. Disclosed more particularly are a method and system for testing an overhead crane runway beam 3D alignment or an overhead crane runway rail 3D alignment using a 3D laser scanner.
Claims9
A non-contact method for measuring 3-D alignment of an overhead crane runway beam or runway rail of an overhead crane, the method comprising:
- (a). providing a separate measurement unit configured to remain stationary during measurement of two rails which collectively form a runway, wherein the separate measurement unit includes a 3-D laser scanner on a support base and no component of the separate measurement unit is positioned on or contacts any of the components of the overhead crane such that the separate measurement unit collects all information without requiring access to the overhead crane or to its overhead crane runway beam or runway rail.
