The kanji 垂 is a pictograph. It depicts a heavy object hanging down from a support, or a branch of a plant that is hanging downwards. The top part represents the support, and the bottom part represents the object or the branch. The bottom part has been simplified over time, but the downward direction is clear. It's a very visually intuitive character, showing the action of something drooping downwards.
