Power Surge (ride)

Power Surge is a high-impact thrill ride designed by Italian ride manufacturer Zamperla. The Power Surge was first operated in 1999, and is produced in both trailer-mounted and park versions. Zamperla recommends that riders be 48 inches (122 cm) or taller; however, 52 inches (132 cm) is more common.
Design and operation.
Six fixed arms are connected in an asterisk pattern, with two sets of two seats attached at right angles to the arms. The arm assembly is connected to a main arm. Twenty-four riders at a time can be loaded onto the ride. Riders are restrained by an over-the-shoulder harness, with their legs dangling free for excitement.
When this ride is activated, multiple movements occur. The arm assembly rotates, the main arm is raised from the stationary position to an angle of approximately seventy degrees from the horizontal. Once this height is reached, the main arm is capable of rotating, with the combined rotations of both sections causing the seat sets to swing and rotate around the point of attachment. The rotating components can move in both clockwise and anti-clockwise directions, and the different movements can be activated in isolation of each other.
The trailer version of the ride fits onto a standard road trailer, and can be assembled or racked in approximately 2 hours by two people.
