Since Doug put it on the splash page yesterday & today and this thread is titled Safety, I have to chime in. I'm not a structural engineer but I am an architect.
Ceiling joists are designed for a uniform dead load of about 2#/SF and no live load. Roofs (in snow areas) are designed for a uniform loading of 30#/SF and certainly not for a point loading (winch) of 125#.
By experience, we all throw things up 'in the rafters' without consequence, but the practice of hauling heavy objects up there with a winch takes it to another level. I don't recommend the practice.
If you need to do so, please find a local structural engineer and do it per code.
