Wheelbarrow capacity is typ 1/6 cu yd

So, sizing with concrete's density in mind
suggests it would never see more than ~700lb load.

Anything that you'd EXPECT to encounter with a
wheelbarrow that would EXCEED that? (i.e., you
wouldn't be lugging gold bullion around in one)

Would OSHA have any words of "wisdom"? Maybe
wheelbarrows are built to OSHA standards more or less.

Hmmm.... that's another possible source of information.
The list of models that Vic provided includes a "double
wheeled" unit rated at 320kg (700 pounds). Hard to
imagine someone making a unit that can't be *moved*
by a human!

I have a neighbor who works for the state ("safety").
I'll check with him when he returns (I think he's been deployed
to TX or CO or one of those other places getting hammered by
the weather, lately).

Thx!
