Attachment 0003 - Drawings 64N554r0.pdf

This is a technical engineering drawing for Upper and Lower Gate Operating Machinery and Strut Assembly Details, prepared for the Tennessee Valley Authority (TVA). The document is a detailed schematic blueprint showing multiple assembly views and cross-sections of gate operating mechanisms, including the Assembly of Gate Strut, Strut Beam, Strut Housing, and associated mechanical components with precise dimensional specifications, material callouts, and engineering notes.

The drawing illustrates several critical subassemblies: the gate strut assembly with detailed keeper plates and strut pins, the strut beam with welding specifications and structural dimensions, the strut housing with sectional views showing internal mechanisms, and various auxiliary lock components for upper and lower gate operations. Each section includes specific measurements, material requirements, welding procedures, and mechanical tolerances necessary for fabrication and assembly. The document references standard engineering practices and includes a revision history block, indicating this is a controlled technical specification used for manufacturing or maintenance purposes related to TVA's hydroelectric gate infrastructure.
