Steel caster wheels for backhoe dolly

[joes_427_vette]

I have been looking around for 3 steel caster wheels that swival and are rated for at least #800 pounds. The backhoe, frame, and dolly will tip the scales at approximately 2100 #. Checked harbor freight, only rubber tires that I'm sure would not withstand the load for long periods of time. Anyone know of a source ?

I ordered a couple of sets of these, but haven't recieved them yet, so don't know about quality -
eBay: 5 x 2 Poly on Steel Wheel – Swivel Caster – Industrial (item 170116598908 end time Jun-03-07 17:35:47 PDT)
I also found these at Rural King:
Rural King Farm and Home Internet Store

I'm building a dolly based on PineRidge's plans:

Check out Surplus Center. They have several styles in cast iron. Here's an 8" swivel style rated at 1000 lbs.

Thanks for the info. Looks like the surplus center has the one I like best for the application. 8" wheel should roll easily also.
