Did you make your purchase? I just bought this a few weeks ago in a pinch. I had a big hole in the garage floor ready to put in the storm shelter I built and to my surprise despite my calculations the small excavator I rented would not lift the thing. With any lifting equipment good common sense goes a long way. I was very careful moving it while the base was lifted, first because it isn't designed to move while loaded and second the load rating goes out the window as soon as you have any movement other than vertical as it is now a dynamic load. If i wasn't in immediate need I would have built one or at least bought one with a little more steel on it. there simple wasn't even enough time to buy some wood for a temporary a frame to just get it done. All in all I am glad to have it now, and for that price with the coupon it is not a bad deal at all.
