ABSTRACT:
For a measuring device, a boom, rotatable arm, guide arm and cross beam form a parallel crank drive which is mounted so as to be swivelable about the vertical axis of a supporting column. A clamping device for the rotatable arm makes it possible to use only a single drive for both a coarse swivel motion and a precision swivel motion for precision adjustment in order to home in on the measuring position. Measuring probes are attached to measuring support bars that are mounted on the cross beam, and are movable in vertical direction.
