All tower shafts were free from lateral
bracing, which enabled the User to place pipes
for data collection within the shaft without
structural interference.
The towers were designed for uniform press-
ure effects with the exception of Station 7,
which required additional guying to withstand
an earlier test event. Weights of the constituent
materials utilized in each 100-foot section of the
tower were established and furnished to the
ser.

The above list shows the zero stations in
numerical
uence with the applicable event
names as used in Operation REDWING.In the
text that follows, the participation of each
station in various events is shown by listing the
appropriate zero Station. The stations are described in numerical order, including information
as to purpose, location, User and starting and
completion dates of construction.

Stations 1, 3, and 6 were 300-foot steel
towers, and Stations 2, 4, and 7 were 200-foot
steel towers; each had a 100-ton capacity cab.
In order to maintain flexibility in use, the
towers were designed in 100-foot increments,
which permitted increasing their heights from
100 feet to as much as 300 feet, requiring only
adjustments to the footings and guys. Tower
components were fabricated in 25-foot modules
for ease of erection.

Final Tensioning of Guy Wires
Each tower had an elevator with a 9-foot x
7-foot platform and a lifting capacity of 6,000
pounds of freight or a passenger conveyance of
2,000 pounds. Lifting power for the elevators
was provided by seven hoists which had been
previously used at the Nevada Test Site. Hoisting speeds were maintained at 75 to 100
feet per minute. The hoists were removed prior
to each event, and in the case of Station 7, the
hoist was made portable, thus enabling rapid
recovery between experiments.
