I want to make a set of gin poles to mount on the back of my truck for picking heavy **** up. I have seen a few pics like AKfabshops but nothing up close and am curious as to what other people have done. I have a heavy pipe rear bumper and was planning on welding hinge tabs to the outside edges of the bumper, so they will not interfere with the tailgate opening and closing and using around 7' poles, so I can mount them inside of my longbed when they are not in use, and so I can have them with me all the time. I need to work the geometry out to see if they will be long enough, I doubt it so if they arent I'll have to come up with some kind of two piece system. To hold em up, I was thinking of making a little "hitch" that has a grab hook and small ATV winch mounted on a stub so I can stick it in my gooseneck hitch. The way it would work is I set the poles up, use the winch to lift them to the desired height, then attach a chain to hold them at that height and use the winch to lift whatever needs lifting. The only part I really cant figure out is the pulley at the top. What do people normaly use? I was thinking maybe a plain snatch block but that would waste a little bit of lifting height. Anyone know where I can get a large pulley for relatively cheap?
