Is there a way to make the hinges stronger?

[eberkain]

See all the movement in this bottom hinge when under pressure.   It doesn't break, but is there a way to have it not do that? 

the big hinge has much less movement, but is so unweildy to actually use.  

Looking at the configs, they look virtually identical.

So I tested the hinges to see how much offset force they can handle, and the big flat hinge is far and away the best. 

So I guess I need to figure out how to build a crane with three of those bad boys. 

Ok, so I redesigned my crane again to try and minimize the angular forces on the hinges and it works like a charm.  

This ore tank is scaled to weigh about 10 tons and this lifts it with ease.
