RSB M50 – Road Blocker

The RSB M50 road blocker by AUTOMATIC SYSTEMS is a high‑security, retractable wedge barrier designed to stop hostile vehicle attacks at perimeter access points. It is certified to withstand a 7.5‑ton vehicle impacting at 80 km/h (or a 3.5‑ton vehicle at 112 km/h), absorbing around 2,000,000 joules of impact energy, making it suitable for airports, military bases, government buildings, and other high‑risk sites. The blocker can be ordered in lane widths from 2 to 6 m, with an obstacle height of 1,000 mm and a relatively shallow foundation of about 500 mm, simplifying integration into existing road layouts.

The RSB M50 operates automatically to raise or lower, typically in about 7 seconds, with an optional emergency‑fast‑rise mode that can deploy the barrier in roughly 2 seconds when required. Constructed from robust steel and designed to meet EN 124 Class D400 for heavy‑traffic road applications, the system combines crash‑tested structural integrity with selective access control, enabling normal vehicle flow when the barrier is lowered and instant perimeter protection when raised. This makes the RSB M50 a key component in hostile‑vehicle‑mitigation schemes for critical infrastructure and high‑security environments.
