I will start a thread and hopefully others will post specific info as well and maybe we can put - in one place - all the different hoist ideas. How do you hoist your plane for float changes and maintenance?
Here is what I did for a Supercub ..........
I have a set of Wipline 2100A amphibious floats. One of the first things I had to do to install the floats was get a hoist setup. Then I had to make a spreader bar for the hoist and also get a hoist. Here is what I did and what I learned.
I purchased a 3/16 thick by 2" square 3 foot long steel tube from the local steel supply company. 14 Bucks. I purchased a Gibralter Shoulder eyebolt # 73108219 from McMaster-Carr (MSC Supply). This is for the center of the lift bar that the hoist attaches to. This eyebolt is rated at 5000 pounds with a safety factor of 5X. Then I purchased two eyebolts # 73108144 for the ends. These attach to the lift rings on the Cub Via 1/2" quick links part # 67785606.
I also got two eyebolts for the Cub # 73108144 rated at 1400 pounds each, again with a 5X safety factor.
I did a little homework on the net and I don't think you want to get a Harbor Freight Hoist. I went to a company called CM and as best as I can tell they make a good hoist (actually they have several lines/grades), and I got the Hurricane (Line/series) Hoist. Cost about 320 bucks. Then I had to make sure the rafters in the hangar would support all this so I had a civil engineer look at my hangar truss system and run some stress analysis to make sure I was not going to pull the hangar down when I lift the Cub. Then I mounted a 4X6 beam in the rafters, per the engineers recommendation, to attach the hoist to. Whew. Takes a lot of work to mount the floats.
My good friend Lytle helping hoist it up. An electric hoist would be nice but since this only gets used once or twice a year it is hard to justify the extra cost. This system works quite well. Be sure to protect your windshield!!
Hope this helps
