The present invention relates to a tool-carrying vehicle for transporting a tool and positioning it over bolt holes in a flange of a vessel, and for moving the tool in translation and/or rotation, the vehicle comprises: a tool-carrying elevator column extending upwards perpendicularly from the vehicle chassis; a tool-passing opening formed through the chassis adjacent to the column and situated in line with the position occupied by a tool fixed to an elevator in the column so as to allow a tool to be passed down through the chassis and inserted into a bolt hole, and to allow it to be raised to its initial position after acting in the hole; and guide wheels and position adjustment templates for guiding and adjusting the position of the chassis on a flange so that a tool lies exactly on the axis of a bolt hole, regardless of the hole diameter. Such a vehicle is particularly suitable for inspecting and maintaining the vessels of steam generators.
