The coaster was a prefabricated roller coaster with an electric spiral lift mechanism. It was one of the first coasters in the world to use this particular lift mechanism, and the coaster was also the first of its model type.〔(List of electric spiral lift roller coasters on RCDB.com )〕 ==Ride layout== The Jumbo Jet, like all electric spiral lift roller coasters, reached the top of its lift hill by way of a gently-graded spiraling helix, before beginning its first drop. Unlike many roller coasters, which use a chain lift or launch, the Jumbo Jet was propelled with small wheel motors up the incline of the helix. These sort of coasters soon became a very common type of steel roller coaster in the 1970s, and were distinguished from later steel roller coaster designs that were characterized by their thicker, tubular-steel tracks. After climbing the spiral lift, riders plunged down a 56 foot tall drop into a series of tight turns in a figure-eight pattern and ending with a double-helix. When it debuted, Jumbo Jet was billed as the fastest of its kind and was known for its views of Lake Erie and steeply banked turns (some at up to 70 degrees).〔(Coast Into Thrills at Cedar Point Park ), ''Pittsburgh Post-Gazette'', June 28, 1978〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Jumbo Jet (Cedar Point)」の詳細全文を読む スポンサード リンク
