About this file
This is a technical drawing document for a Draft Tube Maintenance Platform test stand designed and developed by the Bureau of Reclamation for use at Grand Coulee Dam. The drawing provides detailed specifications for ten test stands to be constructed, each consisting of a 48-inch steel main tube (AISC 5x5x3/8), various steel plates of differing thicknesses and dimensions, forged eyebolts, hex nuts, bolts, turnbuckles, casters, and handles. The bill of materials lists 19 component items with precise specifications, including a 1/2-inch thick 18-inch by 24-inch base plate, 3/4-inch thick top plates, triangular top supports, trapezoid side plates, and Mini Warehouse casters for mobility.
The test stand is designed to support an allowable load of 15,200 pounds-force with a 5:1 ultimate load safety factor. Construction requirements include deburring and chamfering all edges, implementing 1/4-inch minimum continuous welds using E7018 rod, affixing a 1/8-inch rubber pad to the bottom of the base plate, painting in safety yellow, and stenciling stand numbers on the main tube. The document indicates these stands are intended for testing Draft Tube Maintenance Platforms on reasonably level hard surfaces and are to be used in connection with turbine runner and stay vane repair and maintenance operations at the Nathaniel Nat Washington Power Plant at Grand Coulee Dam. This drawing is marked as containing sensitive information requiring appropriate safeguarding and is for authorized use only.
