I'm not one who has trouble moving carboys and small barrels around, but I figured, why push my luck. Moving stuff around the wine room is pretty innocuous, moving 8-10 carboys from the fermentation area to the wine room, a distance of 50 or 60 feet, a little more tenuous. I picked this little gem up a few weeks ago and have been using it, and find it very useful. Rated for 150#, and folding up into an easily storable configuration, for $25, pretty good deal if you need to move carboys, demis, or barrels any appreciable distance. First pic shows it fully opened with a 6 gal carboy in place (I do pop a bungee cord in place when moving wine filled vessels, just in case), second pic is the unit folded up next to the carboy, for scale.
