Track comes close to the riders heads, creating a headchopper effect

A headchopper is any point in a roller coaster where the structure of the ride, theming or another section of track comes close to the rider's heads, or at least appears to do so. The entrance to a tunnel is also a headchopper. A keyhole is a similar feature used on winged roller coasters, where the train travels through a letterbox-shaped hole, often during an in-line twist or zero-g roll.

Safety[edit | edit source]

On modern roller coasters, headchoppers are designed to be out of reach to the tallest rider with both hands up. However if a rider exceeding the maximum height limit is allowed on, the ride could potentially be dangerous.

Often, a pull through is conducted to check that all scenery and supports are at safe distances from the ride vehicle.

Footchopper[edit | edit source]

On an inverted roller coaster, footchoppers create the same effect. Footchoppers are designed so that the rider's legs appear to come close to water, the structure of the ride or other scenery.
