Deer hoist needs re-engineering

[OKRuss]

All, looking for some input(preferably useful) in what design changes I need to make on our deer hoist. It's a 4" square tube metal about 8' tall with another 2.5-3' arm cantilevered. There are 3 pulleys on the top with our hand crank winch mounted on the vertical column. My thoughts were the cable would have pressure on the first pulley, not much on the second then the 3rd pulley pressure would be more downward given the weight of the deer and it pulling straight down.

Well, if you look at the picture and zoom in, you'll see the bolt holding the 3rd pulley is bent way towards the column. Why? I would've thought 100 lb deer hanging would've been enough to keep the cable/pressure straight down. The 2nd pulley isn't even touching the cable. For the time being, I just removed the 3rd pulley. Should the 3rd pulley be lower than the 2nd one?

I did the elaborate Paint drawing since my picture doesn't show the entire setup. If you need me to work on a kick-ass diagram or something for a work presentation just let me know!

If it were mine I would add a 45 support to the cantilever if needed and then hang the deer like this.

You have your pulleys arranged wrong. Hard to explain but if you google it, you can see diagrams of how to use multiple pulleys to decrease the effort required to lift something.

Isn't the picture I posted showing the correct way to double the force with pulleys?

While I don't think I need the 45 for support, I could add one then drill in a cable eye to keep the cable closer to the 45 and run the line just to the 2nd pulley but replace it with a block/tackle. What I didn't want was the cable to start getting in the way if 2 guys are working on the same deer(see next great illustration below).

Mine or Montesa's pulleys?

If it's welded pipe it probably doesn't need a 45 support. I would used the double pulley like the pic I posted to make it easier to lift the deer and then you can run your pull end back to the post if you want.

Circumventing the crank hoist entirely?

Sorry. Montesa is right. And you can add another set of up and down to decrease the pull weight.

I use multiple pulleys to raise 5 gallon corn feeders hanging from tree branches. They only weigh about 45 lbs full but with just one pulley, it's harder than you think and it's especially hard to grip and hold on to the rope while you're tying it off.
