RMC must be supported at intervals not to exceed 10'. In addition, it must be securely fastened within 3' of each outlet box, junction box, device box, cabinet, conduit body or other conduit termination.

I have 2" and 4" RGS turning up from underground to feed equipment on a platform approximately 6' up. Is it sufficient to support it once it is on the platform (within 10' of the ground) or must it somehow be supported at ground level as well? If so, how?

If you don't consider the ground to be a support what did you support the underground portion with?
 
Your supports can be further apart than 10'.
Refer to 344.30(B)

Also you may not need any from underground to the equipment. 344.30(B)(3).
