The Neptune NCRB K4-6 electro-hydraulic crash-rated boom barrier is engineered specifically for active vehicle mitigation and perimeter access control across high-threat, sensitive industrial, and defense installations. Operating on a 380V–420V 3-phase power supply with a 2000 W motor for its 5-meter and 6-meter arm spans, the barrier delivers heavy physical vehicle arrest capabilities. By leveraging heavy-duty structural steel (S235, RAEX250-Quality 37 minimum, or FE 360 galvanised) and reinforced civil anchoring, it reliably protects perimeter checkpoints subject to ram attacks from hostile vehicular intrusions.
Defense Establishments, Military Outposts, and Police Headquarters
Perimeter checkpoints at military sites, air force stations, defense facilities, and police headquarters require high-level kinetic impact resistance to stop aggressive vehicle entry. Certified by ARAI under ASTM 2656-18 (ASTM 2626-18 MP30-P1 / M30-P1), BSI PAS 68:2013 (D/7200/48/90/640), and ISO IWA 14-2:2013 (D/7200 [N2B]/48/90.0.0), the NCRB K4-6 halts a 7200 kg vehicle moving at 48 to 50 km/h with maximum penetration under 1 meter (750 mm). The reinforced foundation and 1000 mm crash beam centerline physically destroy the vehicle's front suspension, making it critical for forward entry gates and perimeter access posts.
Airports, Transit Hubs, and Transport Infrastructure
High-capacity transportation facilities, such as civilian airports, air cargo aprons, and intermodal transport hubs, require continuous automated lane management alongside crash mitigation. The NCRB K4-6 barrier features a 100% continuous duty cycle powered by an internal electro-hydraulic drive system, opening and closing in 4 to 6 seconds. This operational speed maintains vehicle throughput while securing restricted tarmac entries, air cargo loading gates, and perimeter service roads.
Refineries, Chemical Plants, and Energy Facilities
Refineries, power stations, and petrochemical installations face both unauthorized vehicle intrusion risks and harsh environmental conditions. The barrier's cabinet has an IP67 rating with continuous ventilation, operating across ambient temperatures from -20°C to +65°C and up to 95% relative humidity. The structural steel frame undergoes shot blasting, hot zinc spraying, priming, and a final polyurethane topcoat in gray, delivering a 15-year corrosion protection standard conforming to BS 5493:1977 (revised 1984) for polluted industrial environments.
Embassies, Government Offices, and Sensitive Research Centers
Government ministries, research centers, and diplomatic embassies necessitate access control integrated into complex automated security frameworks. The NCRB K4-6 system incorporates microprocessor PLC electronics with auxiliary I/O ports, enabling seamless integration with biometric scanners, RFID readers, radio transmitters, ANPR cameras, vehicle loop detectors, and safety photocells. The included desktop push-button unit provides manual control for guard houses, while optional power backup configurations support UPS or DC motor connections with auxiliary batteries (they are not included) and an optional manual hand pump for continuous readiness during primary power failures.
