Thanks Richard, i've been sifting through the search info. I'm building the shop with 16' walls so a top plate will work for me. What I'm not finding is how much over sizing does a guy want in a lift for the load safety factor? For instance: if a truck is 6k and the lift is rated for 6k that lift is working at 100% duty cycle. Do we factor in 10,15,20% over size for safety?
