When you want to lift or pull more than your own strength will permit, or when you want to make a heavy lifting job a little easier, the rope tackle is a device that can be used.

The idea behind a rope tackle is similar to that of a tackle using blocks and pulleys. In a rope tackle, one lead (end) of the rope has to be fixed. That is, it has to be anchored around a spar or tied through a ring or other piece of hardware that doesn’t move.

Step 1: Form the Fixed Loop

Start with a Butterfly Knot in the desired position along the standing part of the rope.
I had to look up what it is called, but I use a Magnus Hitch rather than Two-half Hitches. It holds the rope tighter so you don't have to slide the hitch right up against the Alpine Butterfly. Makes it easier to untie.
Yes! I RECENTLY came across that alternative. In pioneering terminology, the common name for the Magnus Hitch is&nbsp;<a href="http://scoutpioneering.com/2013/01/29/rolling-hitch/" rel="nofollow">Rolling Hitch</a>, and though I haven't yet used it on a rope tackle during a real life setting, by its very nature I know it works great! It's one of my favorite pioneering knots, and using it simplifies the rope tackle procedure&mdash;namely, less messing around to keep the line taut as the tackle is secured. By the way! To grasp how the Rolling Hitch is functioning, in this application it can be seen as Taut Line Hitch around the bight! What can be more simple?!
However, with further application and thought, when not cinching the hitches flush against the fixed loop, the rope can slide. After all, a taut line hitch (rolling hitch around the standing part) is tied to maintain tension on a guy line, BUT it's also designed to slip.
<p>Thank's, I'm learning. I'v been meaning to learn more about knots.</p>
Did this last summer with scout troop, and we hauled logs around for making our lashed tower. Love these pioneer skills! Well done.
Great stuff Larry. Fairly easy to grasp, it helps to have a rope handy :)
When the line is shorter, just thread the running end through the fixed loop without making a <a href="http://scoutpioneering.com/2013/02/11/knot-tying-terminology/" rel="nofollow">bight</a>.
