The
Skyride at Six Flags Great Adventure
is one of the few remaining dual gondola lifts in the world. It was
originally built for the
1964
New York World's Fair then moved to Great Adventure after the
fair closed. The Skyride carries passengers on a 1/3 mile, four
minute trip from the Fantasy Forest section of the park to the
Frontier Adventures section, or vice-versa. Just about any park
guest can ride as anybody under 42 inches in height (including
children and infants who cannot sit up by themselves) may ride
accompanied by a responsible adult. The Skyride is one of only
three rides in the park (along with the Carousel and Big Wheel)
that allows cameras to be taken on the ride.
The ride consists of two continuous cable loops, held up by six
evenly-dispersed support towers. The cars hang from this moving
cable, each one carrying up to four passengers (or 680 pounds).
These are open cars with four seats (two rows of two, facing each
other). At each station (one at Fantasy Forest, one at Frontier
Adventures), a large
bullwheel with a
pulley-like groove rotates the direction in which the cable is
moving. Incoming cars are transferred from the moving cable to a
stationary steel track, along which the wheels of each car glide.
As each car enters the station, it is "caught" and brought to a
stop by a park employee, who then holds the car in place and opens
the door for the passengers to exit. The car is then pushed around
to the other side of the wheel, where another employee steadies the
car for new passengers to enter. The door is closed and locked and
the car is moved into the launcher. This holds the car in place
until the proper launch interval has passed. At the appropriate
time, the employee pulls a cord which allows the car to roll down a
ramp (accelerating the car to the same speed as the cable) and
automatically clamp onto the cable. Once on the cable, the wheels
above each cabin are not used, but the cable transporting it is
gripped by a clamp between the wheels.
In addition to loading and unloading the cars, each of the stations
performs a substantially different function. The Fantasy Forest
station is the "Drive" station, its
bullwheel is driven by a large
electric motor, with a backup
diesel engine used to unload the ride in case
of a
power outage. The diesel engines
were replaced by
Volkswagen Beetle
motors in 2007. The cars are stored on sidetracks off to the side
of this station when not being used.
The Frontier Adventures station is the "Tension" station, its
bullwheel is linked to a 14-
ton counterweight
underneath the station. The counterweight keeps the cable tight and
prevents the cable from falling all the way down should it slip off
one of the towers. This station has a single sidetrack for storing
cars during breakdowns, but is not normally used for storing
cars.
The Frontier Adventures station is not wheelchair accessible, so
wheelchair-bound guests may board at the Fantasy Forest station,
leave their wheelchair in the station, and take a round trip (which
is not otherwise allowed). Wheelchairs, strollers, large stuffed
prizes, and other bulky items can be transported in their own car
if necessary and picked up by their owners upon reaching the end of
the ride.
The Skyride originally had many more cars than it currently has, it
ran with at least 30 cars per side at the World's Fair with a
launch interval of 12 seconds. It currently runs up to 20 cars per
side with a launch interval of 25 seconds.
The cars currently in
service were relocated from Six Flags Great America
in Gurnee,
IL
, when the Southern Cross and Eagle's Flight Skyride
were removed in order to make room for the construction of
additional attractions. Two of the original World's Fair
cars, with their roofs removed, are currently used as maintenance
cars.
The Skyride does not run in winds exceeding 25 miles per hour. High
winds can push against the cars hard enough that the cable could
fall off a tower. If this did happen, safety devices on the tower
would stop the cable and the counterweight would keep the cable
from falling all the way to the ground. For the same reason,
passengers are prohibited from shaking the cars. One of the towers
is fitted with an
anemometer. When the
wind speed reaches 20 miles per hour, a warning buzzer sounds in
the Fantasy Forest station. When the wind speed reaches 25 miles
per hour, both cables automatically stop. At this point, the ride
must be unloaded and closed, and must remain closed until one hour
has passed without the wind reaching 25 miles per hour. It is also
closed for any
thunderstorm or other
severe weather. It will normally be one of the first rides to close
when severe weather is approaching the park, and one of the last
rides to reopen once the severe weather passes. The cable for each
side is usually replaced every ten years.This skyride is a classic
Von Roll type 101.
The Skyride is one of the more difficult rides in the park to
operate, since it is operated manually and the cable never stops
moving during normal operation. The loader is responsible for
maintaining the correct spacing between cars. This is done by
launching each car when the previous car has reached a
predetermined point on the cable, which is generally between
reaching the first tower and half way to the second on the Fantasy
Forrest side, and almost to the first tower on the Frontier
Adventures side. There is also a "Auto-Launch" feature that sends
the cars once they are locked into place in the launch mechanism.
He is also responsible for making sure the guests are riding safely
and that the car door is secure. The unloader must be strong enough
to catch and stop the cars, as they weigh over 1000 pounds fully
loaded and come into the station at the full line speed of 12 MPH.
He must also be fully alert and aware of the incoming cars at all
times, otherwise a car could come into the station uncontrolled and
crash into the cars in the station, or even derail. The unloader
could even be hit by an incoming car if he's standing too close and
not paying attention.
