How do you make traps like the ones in the movies where you just go up and get hoisted up?

This is a typical hanging foot set, only for large animals will need a greater pull

The branch as the starting mechanism, vigorously need to use other heavy objects, such as high stones, or broken tree trunks, lifting weight to be greater than the weight of the target to be hunted, when the mechanism departs, the weight of gravity by the drop, lifting the prey. This look bullish, actually do a very thin limit, or wolf tooth pile more lethal.
