I like how you have married a Standard Pallet Jack and the shop crane concept. I would like to add two suggestions . Add a pulley system depending up on the expected load weights to reduce the effort required to lift a weight, a heavy weight on a standard winch can be awkward when the weight is increased.
The addition of hold down bolts to secure the crane mechanism on to the Pallet Jack. Dave

I didn't think of adding an attachment point for a pulley - should be easy to add to the nosepiece. The brake winch is a big help for lowering, but it is only rated at 500Kg (half metric ton) - I'll add that suggestion to the version 2

I did look at locking the base to the pallet jack - may still do it, but haven't needed to yet with the weights I've used it on.
The heaviest lift so far has been my Douglas shaper (~400Kg), and my welding table (~ 300Kg). I will be lifting the shaper again in a few months time to put a machine base under it (got to modify the one currently there). I'll run some experiments with some clamps to see what effect it has.
