The FAAC J355 HA M50 automatic retractable hydraulic bollard (FAAC part 116351 / KT Automation code KTI02002J355M50) is engineered specifically for hostile vehicle mitigation (HVM) and anti-ram physical perimeter protection. Certified under PAS 68:2013 (V/7500[N3]/80/90:4.7/10.9) and IWA 14-1:2013 (V/7200[N3C]/80/90:5.0) with an ASTM K12 / M50 equivalence, each single unit delivers an impact energy absorption capacity of 1,852,000 Joules, capable of arresting a 7,500 kg medium-duty truck impacting at 80 km/h.
Diplomatic Missions, Embassies, and Government Ministries
Government chanceries, consulates, and national ministries face elevated threats of vehicular attack. The FAAC J355 HA M50 provides continuous perimeter demarcation with a 1,200 mm cylinder height and 355 mm diameter, constructed from heavy-gauge S355JR EN 10210 steel with wall thickness up to 30 mm. Integrated LED crown lights and a 55 mm white retro-reflective strip deliver 24/7 visual deterrence to approach lanes. In high-threat emergencies, the system integrates with optional Emergency Fast Operation (EFO) hydraulic circuits, raising the 850 kg cylinder assembly in approximately 2 seconds to seal access gates against hostile entry.
Military Bases and High-Security Defense Establishments
Entry control facilities (ECFs) at military garrisons, armories, and naval stations require verified physical stopping power without relying solely on passive gate hardware. The J355 HA M50 delivers 9,000 N of hydraulic thrust force, cycling fully upwards in approximately 6 seconds and descending in 2 to 3 seconds for authorized military transports. If electrical infrastructure is severed during an assault, the hydraulic and mechanical locking mechanisms secure the bollard rigidly in the raised position without downward drift.
Critical National Infrastructure and Utilities
Nuclear power plants, electrical substations, petroleum refineries, and primary water treatment facilities deploy the J355 HA M50 to safeguard against sabotage vehicles breaching outer perimeters. Because the hydraulic drive unit is housed directly inside the bollard assembly beneath an IP67 environmental ingress seal, subterranean hydraulic piping is eliminated, removing fluid loss risks along long utility perimeters. For sub-zero operations, compatibility with the dedicated J355 pit heater (part 116203) extends active field readiness down to -40 °C.
Airports, Transit Hubs, and Centralized Financial Depots
Civil aviation cargo aprons, passenger terminal curbside drop-offs, central bank vaults, and cash-in-transit transfer bays deploy the FAAC J355 HA M50 to establish anti-ram corridors. The cylinder surface features a cataphoresis anti-corrosion primer finished in dark grey metallised polyester powder coating (RAL 7021), coupled with an AISI 304 stainless steel top head and ground crown for resilience against heavy vehicular traffic and road salts.
Multi-Lane Master-Slave Checkpoint Deployments
Wide ingress portals demand synchronized physical protection across multi-lane configurations. System architecture supports scalable site designs using dedicated FAAC JE275 electronic control boards (part 116300):
- Single-Lane Entry Control: Direct 1-to-1 pairing between an individual JE275 control board and a single J355 HA M50 cylinder.
- Multi-Bollard Synchronization: Interlinked JE275 controllers operating in Master-Slave configurations to raise or lower multiple bollards simultaneously across multi-lane avenues.
- Contingency Operation: Integration with the FAAC J355 manual release kit (part 116102) for mechanical lowering during complete site power loss.
