A drawbar extension spring is a specialized helical spring that converts a pulling force into a compression load. Featuring long steel loops running through its center, it compresses rather than stretches under load, utilizing a built-in stop mechanism to safely handle high shock and prevent dangerous over-extension or breakage.
