A support system for a rotary platform (1) provided with an annular support track (19) attached to a lower surface and/or peripheral edge of the platform, said support system including a plurality of support stations (7) spatially disposed below the platform to engage with the support track (20), said support stations (7) including: individual primary support stations provided with at least one support roller (11) rotatable about a substantially horizontal axis to engage in use with a lower surface of the support track to enable horizontal rotation of the platform (1) and bear the platform's weight; individual lateral support stations (13) provided with at least one location roller (12) rotatable about a substantially vertical axis to engage in use with at least one substantially vertical portion of the support track, such that the lateral support station (13) rollers collectively provide a centering force to maintain the position of the platform (1) periphery within defined limits during platform rotation. |
