Catch several ceiling joist with a nice piece of lumber maybe 2x6 .Find exact center of joists using a stud finder or the nail trick,(tap nail where you can feel it slide on opposite sides of joists .Mark C/L of joist in several locations ,get a nice straight line across ceiling so your 2x6?+- with be at a right angle to joists (parallel).Predrill with a small drill bit 3/16" at c?L og joists ,this will help with cracking then u can use some 1/4" lags+- with washers.If u use a 2x6" u can install two lags on eaxh joist,i would cath at least 3 joists or more,never know u could get a huuuuuuuuuuuuuuuuge Buck.Before u install plate on ceiling i would have a couple threaded eyebolts with nuts installed ,better choice than a lagged eyebolt.Find location for one of those hand winches that are on Boat trailers etc ,then u have no problem pulling and holding the weight and tying off load or find a snatchblock pulley system that are sold a outdoor stores for this very reason ,the rope/cord is a little small.Hope this help and makes sence dont need the whole works coming down on you with knife in hand etc,
