A line of longitudinal rows of passenger compartments are swingingly connected between upstanding pairs of hydraulically rotatable screws by means of internally threaded roll-nuts. The line can be raised or lowered with the compartments disposed mutually level and/or axially tilted, by joint rotation of the screws. Each row can also be axially rotated, all in programmed sequence. Seat-restrained passengers are thus exposed to varied and unexpected motion which challenges normal equilibrium feelings. Basic assembly can be permanently mounted on flatbed trailer for highway or rail movement to successive carnival locations upon disassembly of segmented screws and telescopic support towers which hold up the assembled screws.
