The Stovebolt Site Forums The Parking Lot Big Bolts Anyone running a hoist on oak rails?

Looking at putting a hoist on my 49 4400. My grain bed/box has a steel frame sitting on oak rails. The bed frame is bolted to the truck frame using large U type bolts with oak beams between the two. My question is there any hoists on these types of beds or do I just need to look at doing something different? Please help.
