Giant swing amusement ride with oppositely pivoting boom arm and cam arm

摘要

An elevated support beam has a boom arm and two cam arms that pivot in opposite directions between a lower loading position and an elevated operating position. A passenger carriage is suspended from the cam arms and is releasably attached to the boom arm. When the passenger carriage is released from the boom arm with the cam arms locked in the operating position, it swings back and forth but is elevated safely from the ground because of the elevated cam arms. Alternative embodiments include separately pivotal boom and cam arms, a support arm sufficiently thick that the cam arms are not required, and movable solid or fluid counterweights. A method of swinging a passenger includes pivoting the boom arm and the cam arms to the operating position, locking the cam arms in the operating position, and permitting the carriage to swing from the cam arms safely above the ground.
