High Security M50 M30 Wedge Barrier Shallow Mount Road Blocker
The Madoors USA High Security M50 M30 Wedge Barrier Shallow Mount Road Blocker — the Madoors Defender — is a PAS 68 and K12 crash-tested, electro-hydraulically operated rising wedge road blocker capable of withstanding direct impact forces in excess of 1,800 kJ — providing certified protection against Vehicle Borne Improvised Explosive Device attacks at high-security establishments, iconic buildings, and critical infrastructure sites where existing underground services or depth restrictions prevent the installation of conventional deep-foundation road blockers. With a shallow foundation design that avoids the deep excavation required for standard road blockers, the Madoors Defender brings PAS 68 and K12 certified hostile vehicle mitigation to sites that were previously unable to accommodate crash-rated vehicle security barriers due to underground utility constraints.
The Defender rises to a full 1-meter impact wedge height in standard operation — and can be configured with a hydraulic accumulator for emergency quick-raise in under 1 second — with standard 2-meter and 3-meter segment widths, PLC control compatible with virtually any access control system, manual pump backup for power failure operation, and optional real-time remote monitoring of raised and lowered status.
TECHNICAL SPECIFICATIONS
The Madoors USA Shallow Mount Road Blocker is certified to PAS 68 and K12 — withstanding direct impact forces in excess of 1,800 kJ, corresponding to the kinetic energy of a 7,500 kg vehicle at 80 km/h. M50 and M30 ratings cover the American ASTM impact classification system — M50 confirming stopping performance at 50 mph and M30 at 30 mph for the specified test vehicle mass. PAS 68 certification provides independently tested performance documentation to the UK and internationally recognized vehicle security barrier standard.
The blocker is assembled from heavy gauge materials in Madoors USA fabrication facilities — providing the maximum structural strength and durability required for a barrier system that must absorb 1,800 kJ of kinetic energy in a hostile vehicle impact without structural failure or significant deflection. The heavy gauge construction is the engineering basis of the PAS 68 crash-rated performance within the shallow foundation depth that distinguishes the Defender from conventional deep-foundation road blockers.
Physical configuration: standard segment width of 2 meters or 3 meters — with multiple segments deployable in series to cover wider road widths. Raised height: 1 meter — providing the vehicle-arresting element height required to engage the bumper, radiator, and lower engine compartment of all standard commercial vehicles. The barrier consists of a static sub-surface ground frame with foundation support legs and a hinged, rising impact wedge — the wedge rising from the flush road level position to the 1-meter raised blocking position on hydraulic actuation.
The hydraulic power pack is controlled by a PLC — providing the access control integration flexibility to interface with virtually any access control system. Standard operation uses push-button control. The optional hydraulic accumulator enables emergency quick-raise in under 1 second — providing the fastest available road blocker deployment response for immediate threat scenarios. A manual pump provides operator control during power failure. Optional raised and lowered status indication signaling enables real-time remote monitoring of blocker status from a remote control point.
KEY FEATURES
PAS 68 / K12 Certified — 1,800 kJ Impact Resistance
The Defender is independently crash-tested and certified to PAS 68 and K12 — confirming impact resistance in excess of 1,800 kJ. This independently verified certification satisfies the most demanding government, military, and critical infrastructure security procurement specifications for hostile vehicle mitigation barriers. The 1,800 kJ impact resistance covers the kinetic energy of a fully loaded hostile vehicle at highway approach speeds — stopping the most credible VBIED attack scenarios completely.
Shallow Foundation — Underground Service Compatibility
The defining advantage of the Defender over conventional deep-foundation road blockers is the shallow foundation design — allowing PAS 68 and K12 certified crash protection to be installed at sites where existing underground services, buried utilities, and depth restrictions prevent the deep excavation required for standard crash-rated road blockers. This shallow mount capability brings certified hostile vehicle mitigation to iconic buildings, historic sites, urban streetscapes, and critical infrastructure locations where underground utility density has previously prevented the installation of crash-rated barriers.
1-Meter Raised Height — Maximum Vehicle Engagement
The 1-meter raised height of the impact wedge provides maximum vehicle engagement capability — contacting the front bumper, radiator, and lower engine compartment of any standard vehicle and transferring the full impact load into the wedge structural mass and foundation support legs. The 1-meter height is the standard vehicle-arresting element specification for maximum stopping effectiveness across the full range of vehicle types from passenger cars through to heavy goods vehicles.
Heavy Gauge Material Construction — Maximum Strength & Durability
Assembly from heavy gauge materials in Madoors USA fabrication facilities ensures the structural mass and material strength required for the certified 1,800 kJ impact performance within the shallow foundation depth. The heavy gauge specification directly determines the barrier's ability to resist structural deformation and maintain position under the extreme dynamic loading of a hostile vehicle impact at the PAS 68 test conditions.
Rising Impact Wedge Design — Hinged Mechanism
The hinged rising impact wedge mechanism provides a mechanically efficient path from the flush road level position to the 1-meter raised blocking position — with the hydraulic actuation force applied at the hinge pivot to maximize mechanical advantage and minimize the hydraulic force required to raise the heavy-gauge wedge rapidly against the design vehicle impact loading. The hinged wedge geometry also optimizes the angle of impact engagement with the vehicle's front axle and undercarriage during a hostile vehicle attack.
Emergency Quick-Raise — Under 1 Second
The optional hydraulic accumulator configuration enables emergency quick-raise in under 1 second — the fastest available road blocker deployment response, reducing the window of vulnerability between threat detection and full 1-meter barrier height deployment to the minimum achievable with a rising road blocker system. Sub-1-second emergency raise is the critical operational capability at the highest-threat access control positions where a hostile vehicle may be identified at close range with minimal warning time.
PLC Control — Universal Access Control Integration
The PLC-controlled hydraulic power pack integrates with virtually any access control system — inductive loop detectors, card readers, communications equipment, manned guard emergency systems, and any other access control device providing a compatible output signal. This universal integration capability allows the Defender to be incorporated into any existing or new site security management infrastructure without compatibility constraints, from simple push-button guard control through to fully automated CCTV-triggered hostile vehicle response systems.
Manual Pump Backup — Power Failure Operation
The manual pump provides continued operator control of the road blocker during mains power failure — allowing the wedge to be raised to the blocking position or lowered to the access position without electrical supply. This power failure operational continuity ensures that the security perimeter is maintained during power outages and that the road blocker cannot be permanently locked in the lowered position by a deliberate or coincidental power interruption at the access control point.
2-Meter & 3-Meter Standard Segments — Configurable Width Coverage
Standard segment widths of 2 meters and 3 meters allow the road blocker installation to be configured for any road width — with multiple segments deployed in series to cover wider lanes and multi-lane road access points. This segmented configuration flexibility allows a single product type to serve the full range of road widths from single-vehicle lanes through to multi-lane access roads without requiring custom-manufactured oversized segments.
Real-Time Remote Monitoring — Optional Status Signaling
Optional raised and lowered status indication signaling provides real-time remote monitoring of the blocker status from a security control room or remote guard station — allowing security personnel to confirm blocker deployment status without physical presence at the barrier location. Remote status monitoring supports integrated security management at facilities where multiple access points are managed from a central control room.
VBIED Protection — High Security Establishment Application
The Defender is specifically designed for VBIED protection at high-security establishments, iconic buildings, and critical infrastructure — the application scenarios where the shallow foundation design is most critically needed and where PAS 68 crash certification provides the assurance required by government security specifications. Protection against VBIED attacks — where vehicle-borne explosive payloads are carried to the target by driven vehicles — requires stopping the vehicle before it reaches the protected building or infrastructure, and the Defender provides this stopping capability at the full 1,800 kJ attack energy level.
ASSEMBLY & INSTALLATION SEQUENCE
Site Survey & Underground Service Assessment
The road blocker installation position, available foundation depth, underground service positions and depths, road width, segment width configuration, and access control integration requirements are confirmed. The shallow foundation design parameters are verified as compatible with the confirmed underground service positions and depth restrictions.
Shallow Foundation Excavation
Foundation excavation is completed to the shallow foundation depth — avoiding all identified underground services and utilities. Foundation support leg positions are established within the excavation. Hydraulic supply conduits and electrical wiring conduits are installed within the shallow excavation before foundation concrete is placed.
Ground Frame Installation & Foundation Support Legs
The static sub-surface ground frame is installed in the excavation with foundation support legs anchored to the prepared foundation positions. Frame alignment, level, and structural connection to the foundation support legs are verified to the installation engineering specification.
Hydraulic Power Pack & PLC Installation
The hydraulic power pack is installed at the specified position. The PLC is installed and connected to the hydraulic power pack. Optional hydraulic accumulator for emergency quick-raise is connected and pre-charged to the specified pressure. Manual pump connection is verified.
Rising Wedge Installation & Hinge Connection
The rising impact wedge is installed on the ground frame hinge connection. Hydraulic cylinder connection between the power pack and the wedge is made. Wedge travel from the flush road level position to the full 1-meter raised position is verified through multiple complete raise and lower cycles.
Access Control Integration & Status Signaling
All access control interfaces — push-button, inductive loops, card readers, communications equipment, and manned guard emergency systems — are connected to the PLC. Optional raised and lowered status indication signaling is installed and connected for remote monitoring.
Emergency Quick-Raise & Power Failure Testing
Emergency quick-raise from the hydraulic accumulator is tested and timed — confirming sub-1-second raise capability. Manual pump raise and lower operation under simulated power failure is tested and confirmed.
Certification Documentation & Handover
PAS 68, K12, M50, and M30 crash test certification documentation is compiled with site survey records, underground service clearance confirmation, shallow foundation installation records, and PLC commissioning documentation into the project handover package.
