SUBSTANCE: supporting-rotating apparatus has base and rotary platform between which are positioned three rotating wheels and two intermediate members, said intermediate members being mounted between rotating wheels. Central brake is installed on rotary platform and is cooperating with base through joining link which is connected with its upper end through Hooke's universal joint and central brake to rotary platform and with its lower end through the same Hooke's universal joint to base.
