High-Security Anti-Terror Automatic Hydraulic Bollard

The YD-S802B is an ultra-high-security, anti-terror fully automatic electro-hydraulic bollard engineered specifically for high-risk perimeters requiring robust anti-ram protection and military-grade resilience. Distinguished by its 120-ton certified drive-over load rating, this heavy-duty barrier withstands massive kinetic impacts from fully loaded specialized freight carriers and tactical vehicles. The engineered structure integrates 8 heavy-duty reinforcing ribs (350mm length) around the outer foundation barrel, working in alignment with the 850mm elongated inner steel cylinder to distribute localized impact forces deeply into the 1100mm underground matrix. Outfitted with a 3-guide post alignment stability system, IP68 waterproof submersion rating, and a high-flow active bottom drainage system, the YD-S802B delivers uncompromised perimeter defense for ports, military infrastructure, and national critical installations.

Military-Grade 120-Ton Heavy-Duty Load Capacity

Structurally optimized and certified to endure direct, repeated drive-over traffic from 120-ton ultra-heavy container trucks and specialized heavy transport vehicles, making it suitable for the most demanding high-security checkpoints.

Multi-Reinforced Anti-Collision Architecture

Built for anti-terror resilience, the outer foundation barrel features 8 heavy-duty steel reinforcing ribs (350mm length) that work in conjunction with the 850mm elongated inner cylinder to significantly enhance structural rigidity and impact shear resistance.

Deep Burial Stable Ground Anchoring

Utilizing an 1100mm deep burial structural sleeve, this deep foundation placement lowers the equipment's center of gravity and deeply anchors it into the concrete foundation matrix to dissipate severe external vehicular impacts.

3-Guide Post Lifting Stabilization System

Equipped with 3 precision-engineered internal guide posts, this configuration ensures proper vertical alignment and guidance stability during lifting/lowering cycles under continuous, high-frequency deployment.

IP68 Certified Protection & Active Drainage

Achieves a verified IP68 ingress protection rating, ensuring long-term underground operational readiness even when fully submerged. Features a built-in heavy-bottom drainage system (port diameter ≥50mm, wall thickness ≥4mm) for rapid water evacuation during storms.

Fast Access Response & Power-Off Emergency Lowering

Delivers fast and fluid hydraulic access control (rise ≤4.5s, lower ≤2.5s) to mitigate security breaches. Includes an immediate emergency stop function and comes standard with a power-off backup power supply for safe emergency lowering during sudden blackouts.

The YD-S802B anti-terror automatic hydraulic barrier is engineered for ultra-high-security perimeters exposed to extreme impact threats and max-weight heavy axle crossings. Ideal applications include:

Military Facilities, Border Checkpoints & Prisons – The 8-reinforcing rib matrix and 120-ton load barrier provide robust anti-ram protection against hostile or unauthorized vehicle breaches.

International Sea Ports, Freight Hubs & Customs Yards – Engineered with premium 304 stainless steel and a heavy 80kg structural frame to endure constant, high-frequency crushing by heavy multi-axle cargo containers.

Nuclear Power Plants, Air Terminals & Government Facilities – Designed as a certified anti-terror security measure to safeguard critical public infrastructure against high-velocity vehicular assaults.

Q1: What makes the YD-S802B suitable for anti-terror applications?
A: The YD-S802B is explicitly reinforced for high-impact protection. It features 8 external 350mm steel reinforcing ribs welded to the outer foundation barrel that align with an elongated 850mm inner cylinder, providing strong resistance against vehicular ramming attacks.

Q2: Can the YD-S802B withstand heavy container trucks?
A: Yes. The bollard is structurally certified to withstand a continuous drive-over pressure of up to 120 tons, far exceeding standard commercial traffic limits, making it suitable for industrial heavy freight lanes.

Q3: How does the system ensure reliable operation during heavy rains or floods?
A: The core hydraulic mechanics are certified IP68 waterproof, maintaining functionality under subterranean water submersion. It also features a heavy bottom active drainage port (≥50mm diameter) to discharge accumulated rain rapidly.

Q4: What happens during a power outage?
A: The bollard features an emergency backup power supply that automatically lowers the column during a power outage, ensuring the passage remains clear.
