Anti-Ram Telescopic Rising Bollard
The Madoors USA Anti-Ram Telescopic Rising Bollard is a PAS 68 and K12 certified shallow-mount automatic rising bollard — requiring foundations of just 500mm, making it the world's shallowest automatic rising crash-tested bollard. At a quarter of the foundation depth of standard crash bollards and almost half the depth of equivalent competitor shallow-mount products, the Madoors USA Anti-Ram Telescopic Rising Bollard enables certified automatic crash-rated vehicle attack protection at sites where underground services, shallow bedrock, bridge decks, and constrained urban infrastructure prevent standard crash bollard installation. Successfully impact tested to PAS 68 — stopping a 7,500kg truck at 70 km/h with less than 1 meter penetration — with a 900mm raised height, unique double-action retractable design for smooth fast-acting operation, in-house Madoors USA engineering design, and complete rebar cage supplied as standard, the Anti-Ram Telescopic Rising Bollard is the strongest reduced-depth rising bollard available for high-security anti-ram vehicle attack protection.
TECHNICAL SPECIFICATIONS
The Madoors USA Anti-Ram Telescopic Rising Bollard achieves PAS 68 and K12 certification from a 500mm foundation — the world's shallowest certified automatic rising bollard installation depth. Standard crash-rated rising bollards require approximately 2,000mm foundation depth. Competitor shallow-mount crash bollards require approximately 900mm to 1,000mm. The 500mm Madoors USA foundation is one quarter of the standard depth and approximately half the depth of the nearest competitor equivalent — a fundamental installation advantage that opens entirely new site categories to certified anti-ram protection.
The PAS 68 impact test result — 7,500kg truck at 70 km/h, less than 1 meter penetration — confirms crash performance at standard PAS 68 M30 test vehicle weight and above the minimum 48 km/h test speed. The 70 km/h test speed provides a certified performance margin above the minimum requirement, confirming bollard capability against high-speed vehicle attack approaches.
The double-action retractable mechanism is the engineering innovation enabling the 500mm foundation depth — the telescopic bollard column deploys in two extension stages, with the first stage extending from the foundation cassette and the second stage extending from the first. This two-stage telescopic extension achieves the 900mm raised operational height while the fully retracted two-stage mechanism fits within the compact 500mm foundation cassette. The double-action design simultaneously provides the smooth, fast-acting operation required for access control applications and the depth-saving compact retracted profile required for shallow installation.
The 900mm raised height engages the vehicle at the chassis and structural member height across the full range of cars, SUVs, vans, trucks, and lorries — providing effective structural engagement for crash arrest across all vehicle types encountered at protected access points.
The complete rebar cage supplied as standard provides the tensile foundation reinforcement required for the shallow 500mm concrete foundation to develop the impact anchorage load capacity of the PAS 68 test — eliminating separate procurement of foundation reinforcement materials and ensuring correct reinforcement specification at every installation.
KEY FEATURES
500mm Foundation — World's Shallowest PAS 68 Certified Bollard
The 500mm installation depth as the world's shallowest PAS 68 certified automatic rising bollard resolves the fundamental installation constraint that prevents crash-rated bollard deployment at the most important urban security positions — the 500mm depth consistently fits within the service-free zone between underground utilities at typical congested urban street positions, on bridge and elevated road structures, on shallow basement roof slabs, and at any constrained site where the 1,500mm to 2,000mm of standard crash bollards creates an unresolvable underground services conflict. This installation capability directly enables anti-ram protection at positions that standard crash bollards cannot serve.
PAS 68 & K12 Anti-Ram Certification — 7,500kg at 70 km/h
The dual PAS 68 and K12 certification provides the two primary international crash test standard credentials required for government, military, and high-security commercial anti-ram bollard procurement. The 7,500kg at 70 km/h certified stopping performance with less than 1 meter penetration directly confirms that the bollard arrests the full mass and kinetic energy of a heavy vehicle attack before the vehicle penetrates the protected perimeter — the less-than-1-meter penetration confirms that the protected area behind the bollard line remains safe even in the most severe attack scenario.
Double-Action Retractable — Smooth Operation & Depth Saving
The unique double-action retractable mechanism provides the two most important performance characteristics of the anti-ram telescopic bollard simultaneously — smooth, reliable, fast-acting operation in the access control application and the compact retracted profile that enables the 500mm shallow installation. This engineering integration of operational performance and installation depth saving in a single mechanism design is the core technical achievement that distinguishes the Madoors USA anti-ram telescopic bollard from all competitor products.
Fast-Acting Deployment — Rapid Anti-Ram Response
The fast-acting rise from retracted to 900mm operational height provides the rapid anti-ram barrier activation required for vehicle attack response at urban access points — the bollard reaches its full certified impact height quickly enough to intercept an approaching threat vehicle even at the short approach distances available in pedestrianized areas, building forecourts, and constrained urban environments where vehicle attack stand-off distances are limited.
In-House Madoors USA Engineering Design
The in-house design by Madoors USA engineers confirms that the double-action telescopic mechanism, the 500mm foundation optimization, and the PAS 68 performance achievement are proprietary engineering developments — not adapted from standard product platforms. This in-house engineering capability provides the technical authority for the world-record shallow foundation claim and supports the continuous product development of the bollard range.
Underground Services Conflict Resolution — New Sites Enabled
The explicit design objective of enabling certified anti-ram bollard installation where underground services or limited excavation space prevent standard bollard installation directly addresses the most common site constraint that leaves critical urban locations unprotected. The 500mm depth consistently resolves the underground services conflict at typical urban street positions — enabling anti-ram protection at pedestrian precincts, historic streetscapes, bridge approaches, and congested urban sites that have historically been unprotectable with crash-rated bollards.
Easy Installation, Commissioning & Maintenance
The easy installation, commissioning, and maintenance characteristics reduce the total lifecycle cost and operational burden of the anti-ram bollard installation — straightforward 500mm excavation, supplied rebar cage, simple cassette placement and concrete pour, and accessible maintenance access to the double-action mechanism all contribute to the lowest-cost certified anti-ram bollard ownership across the full service life.
Rebar Cage Standard Supply — Complete Foundation Package
The rebar cage supplied as standard with every bollard provides the complete foundation reinforcement package — the installer places the rebar cage in the 500mm excavation, positions the bollard cassette, and pours concrete without procuring any additional foundation materials. This complete supply eliminates the reinforcement specification risk and procurement logistics that bollards supplied without rebar cage impose on the installer.
