Abstract
In an enclosure of a heat exchanger that includes a wall having an opening for access to the enclosure and a nozzle for fluid flow through the wall, an articulate hoist for bringing an articulate manipulator into the enclosure is attached to the wall outside the opening. The lifting portion of the hoist, which is in the enclosure brings the manipulator into the enclosure. The manipulator which is is then attached to the wall outside the opening is adapted for reaching through the opening from inside the enclosure. A tool operator portion of the manipulator is adapted for engaging a nozzle dam for inserting the dam in the nozzle. One type of nozzle dam which the apparatus can install is one that falls within the description of a claim of U.S. Pat. No. 4,957,215.
