[RE-wrenches] Top of Pole Mount Array on Ledge

[Ray]

If you can get anchor bolts in, you can weld on a 1" think plate with 
gussets to the bottom of the pole. We've had to do this a couple of 
times in rock.  We'll pour enough concrete to get a level base, but the 
bolts are epoxied into holes in the rock.  A good epoxy anchor is 
stronger than the bolt itself.  We've also done combinations, where we 
can only get 18" of concrete over the rock, then we epoxy in rebar to 
tie the concrete to the rock, and J bolts set in the concrete to bolt 
the base plate to.
