The static load of a pallet is how much weight you can place onto the pallet without it being moved. As this is confusing, here is an example. A pallet has a static load rating of 20,000 lbs. You will place the pallet on the floor and be able to load up to 20,000 lbs of whatever onto the pallet without damaging the pallet. The pallet never moves. If you need to move that pallet, you will need to remove weight until you get to the dynamic capacity of that pallet. This also holds true when stacking pallets one on top of another. For example, you can stack 4 pallets that have 5,000 lb on them and that would equal your 20,000 lbs static capacity.
