Unloading the pallets was a simple matter using a portable engine crane. The technique was little crude but it worked. We were very careful not to have any person or body part under the pallet while lifted, and other than for photos someone had their hand on it to steady the load. Safety first.
If I was doing it again I would look for a lifting beam or cross beam. This would allow a safer and more controlled method to center the slings and distribute weight.
