Moving fireplace down flight of stairs
Moving fireplace down flight of stairs
(OP)
I have decided to move a 450lb fireplace down 12 basement steps. I'm looking to design and build a simple winch and pulley to control it's descent. I have a boat trailer winch and some pulleys which will connect to a 4 wheel piano moving dolly. What I need to know is the weight the object the fireplace will develope as it changes from a horizontal plane to a 45 degree slope. Any help is greatly appreciated!

weight * sin 45 degrees = 450 * .707 = 318 lbf
Some years ago, I installed a Bridgeport milling machine in my basement, with the help of a local removal guy. The machine had to be completely disassembled, and the heaviest component was the column, which weighed about 700 lbs. This is a comparable exercise to what you are attempting. But one thing the removal guy insisted on was that the stairs had to be shored up with columns from below - this was based on bitter experience. Many stairs are very weakly nailed in position, so unless you are sure about that aspect, I would shore up the stairs first.
