Any engineers out there? Need a simple pallet-elevator

The longer you make the 4 cables from the pallet corners, the more stable it will be--but the higher you'll have to put the pulley above the storage platform.
I think there should be plenty of room above the storage platform - I can walk around up there.

Similar design used for barn lofts forever.......

Lots of pictures of the pulley but not so much on the platform end.

Two to one pulley system make much easier
Good point. Doing some research and learning how this works - it appears that it also lessens the load on the mount point(s) above.

I'm still a little worried about balance. I'd rather do it once and be done than have to go the trial-and-error route.
