1. First in the world Rolling brake system impact absorbing system.
2. Newly invented impact energy absorbing technology.

*One of the important properties of RBS Crash Cushion is absorbing impact energy by using roll force and frictional force generated from the rolling pipe and inducing instruments. Inducing instruments which have harder physical property squeeze the rolling pipe which has less rigidity while generating frictional force and roll force. RBS Crash Cushion is ideally suited for hazardous places such as at the ends of rigid barriers, toll booths, the entrance of tunnel and expressway exit ramps, etc.
