Hi, I second your appraisal of not using the ramp,

I also used a 100mm stack of thin wood planks stacked on top of each other and a 4 metre long pry bar to lift my 1-1/2 ton Ajax manual mill off my pallet truck when it was delivered a couple of years ago.

The pry bar allowed me to sequentially lift at the corners of the base and remove a plank at a time until it was down on the floor.....this was how the machinery mover people moved the mill in when it arrived initially......I just moved it to a new position.

Getting a heavy weight off a springy pallet would be a challenge for anyone.
