Automatic and manual anti-ram rising-arm barriers, tested under real conditions against high-speed vehicle impact, to protect the entrances of sensitive sites.
In everyday use, AMCO security barriers manage access like a conventional barrier. In the event of an impact, the arm locks automatically, with no manual intervention, and holds the vehicle thanks to the retaining device and the steel posts anchored to a 50 cm concrete foundation. Each model has its own certified resistance class: belonging to the range alone does not define performance.
| Threat (vehicle and speed) | Model | Resistance |
|---|---|---|
| 3.5 t vehicle at 48 km/h | AB-C50 | IWA 14-1 · 311,000 J |
| 3.5 t vehicle at 64 km/h | AB-C65 | IWA 14-1 · 553,000 J |
| 7.2 t heavy goods vehicle at 48 km/h | AB-C50+ | IWA 14-1 · 640,000 J |
| 7.2 t heavy goods vehicle at 80 km/h | AB-C80 | IWA 14-1 · 1,777,000 J |
| 7.2/7.5 t heavy goods vehicle at 48 km/h, no power supply | MSB-C50 (manual) | 667,000 J |
| 7.2/7.5 t heavy goods vehicle at 80 km/h, very high-risk sites | MSB-C80 (manual) | 1,777,000 J |
Motorised rising-arm barriers for frequent access, with automatic locking on impact.
Automatic security rising-arm barrier with 135 × 93 mm oval aluminium boom and integrated restraint device. In a crash test it stopped a 3.5 t lorry launched at 48 km/h.
Same structure as the AB-C50, with higher resistance: certified by numerical crash test by an independent Cofrac-accredited body against a 7.2 t heavy vehicle at 48 km/h.
Automatic security rising-arm barrier with 135 × 93 mm oval aluminium boom, certified by numerical crash test by an independent Cofrac-accredited body.
The most robust automatic barrier in the range: 185 × 100 mm aluminium boom with integrated arrest device. In crash tests it stopped a 7.2 t lorry travelling at 80 km/h.
Barriers rotating through 180° in both directions, with no electrical power supply and padlockable in the closed position.
Manual anti-ram barrier with two-way rotation, for protecting sensitive sites. Stops a 7.2/7.5 t heavy vehicle at 48 km/h with negative penetration. 120 × 120 mm steel boom, Ø 250 mm posts, galvanised and epoxy-coated.
Manual anti-ram barrier with two-way rotation, for very high-risk sites. Physical crash test: 7.2/7.5 t vehicle at 80 km/h stopped with less than 2 m penetration over a 6 m clear opening. Numerical simulation: 30 t vehicle at 48 km/h up to 10 m.
A proven solution for every professional environment where confidentiality, compliance and operational continuity are essential.
Data sheets and test certificates for every model are available on request.
A Merfori expert will get back to you to identify the barrier suited to the vehicle and speed to be stopped.
