Malcolm,
Makes sense to me. So as long as you only use it on one level, it will be fine.
It just occurred to me, I wonder if swivel wheels might work here. A second set that contacts when the cart tilts back would be helpful both when moving forward and sideways.

It's the shock load (600lb) from dropping down steps that will cause the bending,

Malcolm,
On the other hand, if it can handle 300 pounds, I'd say it is a great design.

You beat me to it, the bending moment on the support shaft worries me also. Moving the pivot bearing closer to the wheels and increasing the support shaft diameter would help.
