Fire Ball is an amusement ride manufactured by Larson International. It is the third of a series of Larson rides with similar designs, the first being the Super Loop, and the second the Ring of Fire. Several variations of each exist (ex. Space Raiders, Mega Loop, etc.) The rides run the same but the older models have a caged train, whereas the Fire Ball has an open face-off train. Also, some owners of the older Ring of Fire rides have had the caged train replaced with the new Fire Ball train.
The rides are similar in design. There is a large steel boxed-track loop attached to a concrete base or portable trailer with supporting outriggers and steel cables. In this boxed track is a multiple-piece pivoted end-rim (inertia ring) with wheel dogs attached settled within this boxed track. On one section of the rim the train is snugly placed. The rim is run through a shock-absorbent tire drive, which drives the train around the loop.
The ride's train is rocked back and forth at a generous rate, as not to put too much stress on the tire drive. The train elevates on every pass through the station until the ride has gained enough momentum to make it completely around the loop. Once so many consecutive loops are made the train can be shifted to go the other direction. The train can also be hung upside down (stop at the top).
Most if not all of the Super Loop-styled rides are manually operated with a toggle handle. Most of these rides have a dead mans operators chair to detect the absence of an operator, as not to move if the handle was just bumped without someone sitting on the chair. Operators of these rides have to be knowledgeable of weight distribution and speed-to-distance ratio.
Since the Super Loop-styled rides are tire-driven, even the slightest water build-up on the rim can cause the drive tires to hydroplane on the rim. This action keeps the ride from completing its loop and can sometimes make a loud annoying squeal. It is also not good to operate this ride in frequent lightning.
