Ferris Wheel ,designed and constructed by engineer George
Washington Gale Ferris, Jr.
At a height of 80.4 metres
(264 ft) the mamoth Ferris Wheel was the largest attraction at
the Columbian Exposition.
The wheel rotated on a 71-ton, 45.5-foot axle, at that at time
the world's largest hollow forging, manufactured in Pittsburgh
by the Bethlehem Iron Company and weighing 89,320 pounds.
There were 36 cars attached
to the Ferris Wheel, each fitted with 40 revolving chairs able
to accommodate up to 60 people, a total capacity of 2,160 riders.
The wheel carried some 38,000 passengers daily and took 20 minutes
to complete two revolutions, the first including six stops to
allow passengers to exit and enter and the second a nine-minute
rotation. Each rider paid 50 cents.
Ferris, a visionary builder,
was dedicated to the to the monumental structural ideals that
marked the early 20th century and included mansions and bridges.
