Klemson, When I used those large barrels that I spoke of above, I had them on a stand (built out of 2x6's) so that a carboy or a barrel on a dolly would fit underneath the spigot. I found that worked well. I positioned the barrels on the stand, crushed my grapes directly into the barrel and fermented. When time came for secondary, I moved the wine to barrels (I had a 20 gallon and two 15 gallons at the time) and I did secondary in the barrel. When secondary was finished, I applied the bung to the barrel. I had wooden spigots on the barrels to remove the finished wine. It was all gravity until I bought a pump/filter set up.
