ABSTRACT:
An accurately indexed rotatable tool positioning table for use with inspection and repair apparatus remotely disposed within the channel head of a steam generator is shown. The table is automatically rotated by a motor to predetermined positions and an angular position resolving mechanism in engagement therewith provides an output signal responsive to the angular movement for accurate position determination and control. An indexing pin is received in an indexing bushing in the plate to insure accurate, repeatable positioning of the plate, and switch means are associated therewith and operatively connected to the tool energizing circuit to prevent operation of any tool until the indexing pin is properly seated in the bushing and to prevent the positioning motor actuation until the pin is fully withdrawn from the bushing.
