First off I don't have any supporting images to speak of.
I bought 150' of 3/16" 100% Dyneema rope. It's stout enough to winch a Jeep or truck.
I bought a small single pulley and a double pulley. Both have aluminum sheaves. They are Bluewater units.
I bought a CamJam XL (XT?) which is a combination carabiner/pulley/locker. It's not really a pulley but serves the same purpose. It has a locking mechanism which holds the rope from back-slipping when you pull. That's important.
A couple of decent sized quality aluminum carabiners from REI are handy.
Since moose die where they will, you're not guaranteed of a stout tree or other anchor in exactly the right place. You need ground anchors. I brought 4 pieces of 18" aluminum conduit to drive in the ground. The problem was rocks after about 12". The anchors held but they bent in a couple cases. So I'm still looking to improve my anchor system. I just ordered some Wolf Fang anchors to try during the off season. In any event I would bring 4 anchors every time to distribute the pulling pressure.
With a single pulley, double pulley and the CamJam I can create a 4:1 pulling advantage. After the first pulley, every pulley basically reduces pulling effort by 50%. It's not entirely that simple, but 3 pulleys will allow me to pull 1000 pounds of resistance with 250 pounds of effort. A fourth pulley drops that to 125 pounds. Things like friction, angle, pulley efficiency etc will all reduce the advantage somewhat.
Also you could theoretically use 550 (pound) paracord to pull 2,000 pounds in a 4:1 system. That's because there are essentially 4 lines traveling between the pulleys and each of the lines is handling 1/4 of the total load...or resistance.
All my pulling gear goes in a zippered bag just big enough to hold it. That way I've got it all if I need it.
