Retractable barriers that stop ramming vehicles and spiked tyre killers that block unauthorised passage, for the protection of sensitive and very high-risk sites.
AMCO road blockers are hydraulically operated retractable obstacles: at rest they sit flush with the road and let vehicles through; in a few seconds they rise and stop even a heavy vehicle travelling at high speed. LBA spike barriers are rows of retractable spikes which, standalone or combined with a barrier or a gate, prevent unauthorised vehicles from passing.
| Threat (vehicle and speed) | Model | Resistance |
|---|---|---|
| 7.2–7.5 t heavy goods vehicle at 48 km/h, very shallow excavation | RB50-C50 FP | 640,000 J · numerical crash test |
| Two 7.5 t vehicles at 64 km/h, one after the other | RB90C65 | 1,860,000 J · height 90 cm |
| 7.5 t heavy goods vehicle at 80 km/h, very high-risk sites | RB80-C80 | 1,860,000 J · penetration < 1 m |
| Heavy goods vehicle at 80 km/h, maximum energy | RB100-C80 | 2,900,000 J · penetration < 1 m |
| Passages to be blocked with spikes, heavy traffic | Herse LBA H20 / H10 | Axle load 40 t / 25 t |
Shallow-mount road blocker with remote hydraulics and a soft, deformable front that remains operational after an accidental impact. Excavation of around 30 cm, installation in under 48 hours.
90 cm high road blocker with remote hydraulics and soft front. It stopped two 7.5 t vehicles at 64 km/h, one after the other, and remained operational; in numerical simulation it stops a 7.2 t vehicle at 80 km/h.
Road blocker for very high-risk sites. Double crash test: a 7.5 t vehicle at 64 km/h and then at 80 km/h, with penetration of less than 1 m. Height 80 cm.
The strongest retractable barrier in the range, with remote hydraulics and an excavation depth of less than 50 cm. It stops a heavy goods vehicle at 80 km/h with less than 1 m penetration and remains operational.
Hydraulically operated retractable spike barrier for high-traffic sites. 20 mm spikes, 21 cm high, 1.5 s operation. Standalone or combined with a barrier or a gate.
Automatic reversible spike barrier, linked to the operation of the barrier. 1 and 1.5 m modules, 10 cm high spikes; in the event of a power failure it stays lowered.
A proven solution for every professional environment where confidentiality, compliance and operational continuity are essential.
The certified performance of each model (vehicle, speed and test conditions) is given in the technical data sheets, available on request.
A Merfori expert will get back to you to identify the obstacle suited to the vehicle and speed to be stopped.
