Abstract
A tower (150, 200, 250) is disclosed which can be used for an amusement ride, having gondolas (20) or for advertising, having an advertising sign (252). The tower has a lower section (16) and an upper section (18) and a lifter, such as a hydraulic cylinder, to lift the upper section (18) between a retracted position and an extended position. At least one cable interconnects the gondola or advertising sign and the lower section so that the gondola or advertising sign is lifted at twice the rate as the upper section. The tower can be mounted on a rotatable base (152) which rotates the entire tower about a vertical axis. Also, counterweights (202) can be used to reduce the load necessary on the lifter to lift the upper section.
