Abstract:
1. A system for delivering a tool to opposite sides of an underlying tubular body, comprising: a motorized trolley assembly configured to ride on an upper lip of the underlying tubular body at the same time a refueling operation is underway without obstructing fuel from being moved within or into or out of the core during the refueling operation; a substantially vertically supported column assembly having a first part rotatably mounted on the trolley assembly; an arm member having one end attached to the vertically supported column assembly and a second end portion laterally extending from the vertically supported column assembly and spaced from the first part such that rotation of the column assembly positions a peripheral end portion of the laterally extending arm member on an inboard side or an outboard side of the underlying tubular body, providing the peripheral end portion of the laterally extending arm member access to both the inboard side and the outboard side of the underlying tubular body; an extendable pole assembly having a first part attached to the laterally extending arm member and a second part spaced from the first part of the extendable pole assembly for extending the second part of the extendable pole assembly to a preselected elevation below the upper lip of the underlying tubular body; and a tool adjustably attached to the second part of the extendable pole assembly whereby the tool may be tilted or rotated while at the preselected elevation below the upper lip of the underlying tubular body on either the inboard side or the outboard side.
