The flexible bollards are absorbing the impact energy, due to this absorption there is almost no energy arriving at the ground fixing. Breaking out is effectively prevented. Due to the special flexible material there are no damages on the bollards or vehicles, so the cost of damage repair bills reduce. Due to the signal color and usage, the bollard is ideal for protecting machines, equipment and workers from damage. An additional variant is the bollard with moveable cuff which absorbs even more impact energy than the standard bollards.
