ABSTRACT:
A rotating platform for play parks is damped by utilizing the principle of a shock-absorbing fluid cylinder. As the platform rotates, the length of at least one fluid cylinder is caused to change, thus resisting rotation of the platform. This discourages abuse of the platform by older children seeking to rotate the platform at a high speed while a younger child is trapped on it.
