This photo from 1979 shows a Lawrence Livermore National Laboratory employee opening the world's heaviest hinged door, which was eight feet thick, nearly twelve feet wide, and weighed 97,000 pounds. A special bearing in the hinge allowed a single person to open or close the concrete-filled door, which was used to shield the Rotating Target Neutron Source-II (RTNS-II) -- the world’s most intense source of continuous fusion neutrons.No side bolts. Looks odd.
I've seen several of those over the years including a nearby neighbor. I just keep mine parked in the garage. I'm odd - vehicles in the garage versus tons of crap that needs to be hauled off or thrown away.
