ABSTRACT:
An inspection carriage provides for remote inspection of the Z-shroud and snubber regions of the blades of a steam turbine, while the blades remain in the turbine. The carriage includes a non-destructive inspection probe such as a meandering wave magnetometer probe or eddy current probe mounted on a slider, so that the probe may be moved along a radial axis, skew axis, axial axis, and rotation axis. Cameras are provided on the carriage so that the probe may be remotely guided into the region to be inspected.
