Mr Allen;
If you raise the loader a little higher or curl the bucket a little further back, you will be surprised at how fast the chains unhook and the load crashes to the ground. I am not singling you out, but just using the picture as an example.
I think the bucket hooks should be 4" in from the ends of the bucket, and then the chains should be run over the cutting edge. No matter how much lift or curl the chains would always remain hooked, unless they slip off the end of the cutting edge. Not even in the dark with wind and rain and the operator in a hurry. Not that you would be changing shocks in the rain,
