The behaviors of coupled cylinders loaded with identical granules rolling down an inclined plane were explored. The critical rolling angle depends on the granular loading fraction in both cylinders, the maximum of which is achieved when both cylinders contain equal volumes of granules. Both mathematical and experimental studies for three types of granules have been conducted, demonstrating that the model reproduces the experimental observations remarkably well. Finally, the concept of a new "granular braking" system is proposed, and a simple demonstration has been executed to show that the concept is working, giving an opportunity that the concept that might be a candidate for the granular transportation mechanism on an inclined plane or road using large and heavy containers.
