A suspended roller coaster is a type of steel roller coaster in which the car hangs from the bottom of the rolling stock by a pivoting fulcrum or hinge assembly. This allows the car and riders to swing side to side as the train races along the track. Due to the swing designs, these roller coasters cannot invert riders.
History
One of the earliest suspended roller coasters was known as Bisby's Spiral Airship, built in Long Beach, California in the early 1900s. Riders on Bisby's Spiral Airship rode in square gondolas suspended from the track above, which were then carried via lift hill to the top of a tower. The gondolas then rolled down the track, which spiraled down the tower back to the loading platform. The attraction operated at least until the mid-1910s. Featuring multi-car trains and a 2700-foot twisting, spiraling layout, Alpenflug was a hit during the 16-day fair. Dutch designer Vekoma manufactured a suspended model dubbed "Swinging Turns," of which three copies were constructed. Vekoma offers both Arrow-style traditional car designs as well as floorless cars where the riders' feet dangle, similar to Vekoma's inverted coasters but the cars are able to swing. In 2001, Vampire at Chessington World of Adventures was modified to use Vekoma's floorless trains. Caripro, another designer based in The Netherlands, manufactured twelve suspended roller coasters and American designer Setpoint manufactured four.
