In 1955 department of the interior film about the planning and the building of hoover dam. The story explains the engineering feat necessary for construction and promotes economic and recreational benefits provided by the structure. Build a dam in the wilderness and the world will beat a path to it. For many centuries, this was a lonely canyon unseen and untouched by man, scorched by a desert sun, scolded by an angry river slashing its way to the sea. Now it lies peaceful and silent except for the gentle hum of a hydroelectric power plant, the bubbling up of water, the cheerful sounds of america and the world on the move who see this pioneer multipurpose. Eclamation project man built millions come to this spot to see this engineering wonder, to hear the story of hoover dam. Ladies and gentlemen, we are standing on the powerhouse ram
Served municipal and industrial needs of the pacific southwest, generate hydro electric energy and provide various other multipurpose benefits. The clear waters have opened up the fast, new recreational fish and wildlife Vacation Land for america. Picnic, go boating, swim, fish, and enjoy these important out door recreation products. Hoover dam worked around the clock to serve water and power needs. Falls over 500 feet through the spin stocks to spin the giant turbine wheels and then discharge to the river. This action is completed at downstream dams. Transformers step up hoover dam voltage as it comes from the generators. Lines carry this power up over the powerhouse roof to the switch yard. There it is transmitted over lines across the desert. The river flows south ward. Along the way man diverts from the controlled scream to sustain his prosperous way of life. 67 miles downstream davis down reregulated the colorados flow releasing water through its power plant turbines to irrigators
They removed temporary slabs over the relief valve outlets. Liners assembled in these opens were set in concrete. The turbine scroll case sections were lowered into the pit. Sections were levelled, bolted together and aligned. The completed scroll case was then anchored in concrete. Later the turbines water wheel attached to the bottom end of the shaft was installed inside the case. The butterfly valve was assem e assembled on the generator floor and later connected between the feeder pin stock and the turbine scroll case. Meanwhile the generators two main parts took form. Steel lamination plates were stacked around the row rotor frames. Coils were locked into place and connections were made. The power house lifted it from its erection bay and carried it gently to its foundation over the turbine bit where it was lowered and bolted into place. 466ton rotor was moved from its erection bay. Guide and thrust bearings and other parts were added to complete the assembly. After test runs n8 w
Miles an hour. President richard nixon, who had talked with the astronauts by telephone while they were on the moon, was waiting aboard the recovery carrier to welcome the returning voyagers.
