Just wanted to share a success story in getting a heavy piece of machinery (10' slider, SCM 315es) off a pallet and onto the floor. I have a pallet jack but not a gantry crane. I used rollers as suggested in this old thread, using some scrap 3/4" EMT.
Initially I tried to push the saw across the pallet but the smooshiness of the pallet kept the wooden feed from sliding.
The saw ships bolted to four blocks which in turn are nailed to the pallet. I didn't want the EMT rollers marring the paint.
I then levered the saw up a bit and slid the rollers under the feet. I of course first removed the nails from the wooden feet.
At this point the saw will move very easily with a shove or more delicately with 2x4 prying from the side. The movement was slow, precise, and controlled. Here I have the saw towards one side of the pallet and have ready my rails. These were a stack of 1x4 + 4x4 which were pretty close to the level of the pallet. As each foot came off the pallet I would ready a roller on the rail.
Fully off of the pallet. However the saw was still a bit too high for my jack so I cheated with some 2x4 blocks. All I was doing here was lifting the saw up a bit, removing the rails, and setting it back down on stacked 2x4s.
Back in the safety zone! At this point I could up up the saw and get it directly onto the floor.
