Road Blocker is an electro-hydraulically operated rising step obstruction that rises above the ground level on giving a valid input signal and thus prevents unauthorized intrusions at entry/exit points of high security (Z+) premises. When in lowered position the vehicles can pass through, thereby providing a good, enhanced security blockage system. The housing and the blocking element of the Road Blocker are designed in full core steel profile construction with TESCON 4S coating, ensuring maximum safety against corrosion. The impact face of this road barrier is reinforced with steel ribs and impact plates to transfer mechanical forces to reinforced concrete foundation.
