Susan;
We use the 4 step plastic stair stands from this company for one of our 500's and a 600, both shielded:

They do have steel bolts that we replaced for a nominal cost with SST but the stairs can hold 500 lbs. It is quite stable, is easily moved around and I use it for helium fills.
Thanks

Subject: AMMRL:platform/ladder for 600
Everyone:
I have an unshielded 600 NMR (not in a pit). I am using a regular aluminum ladder for filling and sample insertion. However, this ladder has a 275 weight limit and I have some users who exceed this weight limit. Additionally, I would like a more stable platform for helium fills. I'm getting a little bit (just a little bit!) older and I am starting to get a little goosey on the 600 ladder. Does anyone have any suggestions on a better situation and perhaps a vendor?
Thanks!
