Neither is a road, but 1/4"/ ft is still a minimum cross slope. Otherwise it won't drain, and the equipment frame will rust. You can use 1/8" / ft if you are very careful, but you run the risk of a problem later should the pad settle.
6% is the max superelevation on highways anywhere you have snow and ice. Otherwise a stopped vehicle will slide. We use that for parking lots for the same reason.
