Summary

Significance: The crane was the largest in the world when it was completed and is a landmark in American engineering. Roller bearings support a large circular gear mechanism located on top of the portal and allow the crane boom to rotate. The boom and cantilevered trolley ways of the crane are supported by an external framework of steel girders anchored to the circular gear. The crane hoists can be racked in or out along these trolley ways...

Dams under construction. Watts Bar Dam, shown here under construction, has a semi-outdoors type powerhouse with an enormous gantry crane (to the right of the picture) for installation and removal of units. The project is further distinguished by a control building which is entirely removed from the hydro plant, being located some 120 feet higher on top of a steep cliff and with direct connection to the switchyard behind. The windowless left wing of the control building houses the control room; the tower-like structure in the back accomodates air conditioning, restrooms, etc. The glass wall, upper level, contains the reception room with a broad semi-circular overlook terrace, the story below the terrace devoted to offices
