4배 더 강력한 고리바 ( 화물차 매듭 ) 매는 방법 How to make 4 times more powerful trucker's hitch? ( ENG, Sub )

In the last video, we learned about the scientific principles contained in the trucker's hitch, and explored various knot methods that applied it. In this video, we will use this scientific principle to learn how to tie a 2x and 4x more powerful trucker's hitch. This is a way to increase strength by adding the moving pulley we learned in the last video using a rope. If you only know the principle, it is not difficult to knot, so it is helpful to use it when you need to fix heavy objects or strong binding.
