I also experimented with my block grab. Initially I tried it out with my crane. It worked well, but it was quite troublesome and it had it's short comings.
I decided that a gantry was the go. I built one out of the timber I salvaged. Quick calculations suggest I should not come close to the wood's rupture point.
Assuming a 1" x 8" beam that is 4m long, strength rating of S4, it should be able to handle 1 ton before breaking - yes well in theory.
I'll probably find the gantry more useful in stacking the stones. Here is my stack of stones...
