(DRAFT) TPlans - BAR E-Gate Lifting Machinery.pdf

This document is a set of certified final engineering plans for emergency gate lifting machinery inspection at Barkley Lock and Dam on the Cumberland River in Lyon County, Kentucky, prepared by the U.S. Army Corps of Engineers, Nashville District in November 2025.

The plans provide comprehensive technical drawings and specifications for the upstream emergency gate hoist system, including detailed schematics for the machinery base, hoisting equipment, drum and shaft assemblies, gearing systems, pinion shafts, bearing and bushing components, control equipment, and wire rope assemblies. The drawings encompass multiple sections showing the gate lifting mechanism from various angles, including plan views, elevations, and cross-sectional details. Key components documented include the bull gear, intermediate and end drums, primary and secondary speed reducers, motor support structures, brake systems, drive gears with limit switches, and the complete hoist rope assembly with spacing and attachment details. The specifications indicate structural steel construction, stainless steel wire rope materials, and precision bearing and bushing installations. These certified final documents serve as the authoritative construction and fabrication reference for the emergency gate lifting machinery system inspection and any subsequent repair or replacement work at the Barkley Lock facility.
