One is for a 48 pound tandem, and the other two for 40 pound kayaks. The tandem is in the garage, over the center aisle, so I can get it out without moving the cars. The Kayaks are in the barn, so I had to add extra rope for the higher trusses. For the triplet, you could combine two sets of pulleys and hooks for extra load capacity and easier pulling. It just takes more rope. And I definitely agree with twocicle about screwing the lift to a board and attaching that to several ceiling joists, especially if they run perpendicular to the bike.
I found this thread through searching. I just ordered this hoist and will let you know how it works. The tandem might be more than 50 pounds, but I'm comfortable pushing these limits, since I figure they are issued conservatively.
