When I was a little kid, I used to hang out in the our folk's garage and watch as my brother and his friends hoisted V8 engines out of cars using a hand-cranked winch. The winch was attached to chains that hung through holes poked through the garage ceiling. I remember questioning my big brother. Where do those chains go? Won’t daddy be mad that you poked holes in the ceiling?
There’s a steel beam above the garage ceiling in many houses (in all houses?). That's what that chain was wrapped around up there. Later in life, I actually had a job in construction for a short time. I was working for my big brother, framing houses. When we were building the garage, we had to set the steel beam in the ceiling of the garage, a serious task, because that beast is really heavy. Everybody around would stop what they were doing and come help lift the beam into place.
