产品概述

减速带式遥控破胎器——隐蔽式减速带外观·216枚空心不锈钢放气钉·150米无线遥控瞬间触发·20吨承重机动布防车辆拦截系统（亦称减速带式遥控破胎器、遥控阻车路障）是一款专为执法部门机动设卡与车辆拦截设计的智能型警用车辆阻断装备，属于特警反恐应急、公安侦查抓捕、重大活动安保及要地周界防控领域的核心战术拦截装备。该产品采用与普通道路减速带无异的隐蔽式外观设计，内藏216枚高强度空心不锈钢破胎钢钉，通过无线遥控器在150米范围内瞬间触发钢钉同步弹出，可在数秒内将一条普通车道转化为强制车辆阻停防线。其模块化设计将整机分解为36块可快速拼接的路障板，总重量不超过25公斤，单人即可完成快速铺设与回收，实现真正意义上的“流动布防”——不影响道路正常通行，撤离后不留痕迹。系统专为特警反恐拦截涉爆涉恐嫌疑车辆、公安设卡抓捕驾车逃逸犯罪嫌疑人、重要场所入口防车辆冲卡以及监狱边防车辆通道强制管控等高风险执法场景深度定制，从根本上解决了传统固定式阻车桩部署僵化、警示式路障无法拦截蓄意冲卡车辆以及大型车载路障转运不便的实战痛点，能够为一线执法人员提供“隐蔽伪装诱敌深入、遥控远程安全触发、高效放气柔性制动、机动快速灵活部署”的战术级车辆拦截能力，是经公安部《GA/T 421-2003 穿刺放气式路障》标准检验认证的标准化警用路障装备。

技术原理

该装备基于机电一体化无线遥控触发与穿刺放气制动原理协同工作。在待命状态下，设备以减速带形态平铺于路面，外形尺寸为650cm×27cm×5cm，外观与普通道路减速带高度相似，使驾驶员在接近时不会产生警觉或紧急制动避险行为，确保目标车辆以正常行驶速度平稳驶入拦截区。设备内部沿减速带横截面阵列排布216枚高强度空心不锈钢放气钉，每一枚钢钉均处于压缩待发状态，由贯穿整套路障的连杆式机械触发机构统一锁定。

当目标车辆的前轮或后轮完全进入路障区段后，位于安全距离外（有效遥控距离≥150米）的操作人员通过无线遥控器发射加密触发信号。路障内置的接收模块在验证信号完整性后，控制额定DC 12V的机电驱动单元瞬间释放锁止机构，全部216枚钢钉在弹簧推力下同步弹出，钢钉尖端在车辆轮胎接地压力的辅助下快速刺穿胎面橡胶层。由于钢钉采用空心结构，刺入轮胎后形成持续开放的放气通道，轮胎内的压缩气体在数秒至数十秒内高速泄漏，实现非爆炸性、非破坏性的柔性和可控制动——车辆并非因撞击或翻覆而停止，而是因轮胎持续失压丧失行驶能力，从而在最大限度降低对车内乘员及周边人员伤害风险的同时，可靠达成阻停目标。

整套系统由36块模块化路障板通过连接件拼接而成，单板重量轻、携行方便，可在数分钟内完成道路宽向铺设或回收。设备结构材料采用高性能增强塑胶与不锈钢组合，整机最大承重达20吨，可耐受各类中小型车辆反复碾压而不发生结构变形或机械故障。遥控系统具备抗干扰设计，响应速度≤1次/秒，确保在复杂电磁环境下指令传输准确、动作可靠。待机状态下设备表面可正常通行车辆与行人，不影响道路的日常使用功能，完全契合执法部门对设卡装备“平时不扰民、战时快响应”的双重需求。

Product Overview

The Speed Bump Style Remote-Controlled Tire Deflator — Concealed Speed Bump Appearance, 216 Hollow Stainless Steel Deflation Spikes, 150m Wireless Remote Instant Trigger, 20-Ton Load Capacity Mobile Deployment Vehicle Immobilization System (also referred to as the Speed Bump Style Remote-Controlled Tire Deflator or Remote-Controlled Vehicle Obstacle) is an intelligent police vehicle interdiction device specifically designed for mobile checkpoint establishment and vehicle interdiction by law enforcement agencies. It constitutes a core tactical interdiction equipment in the fields of special police counter-terrorism emergency response, public security investigation and arrest, major event security, and perimeter protection of critical sites. This product adopts a concealed exterior design indistinguishable from ordinary road speed bumps. Concealed within are 216 high-strength hollow stainless steel tire-deflation spikes. A wireless remote control with a range of 150 meters instantly triggers the synchronized deployment of the spikes, converting an ordinary traffic lane into a mandatory vehicle stopping line within seconds. Its modular design decomposes the entire unit into 36 quickly connectable roadblock panels with a total weight of no more than 25 kilograms, enabling rapid deployment and retrieval by a single person, achieving genuine "mobile defense"—without impeding normal traffic flow and leaving no trace after removal. The system is deeply customized for high-risk law enforcement scenarios such as special police counter-terrorism interdiction of vehicles suspected of carrying explosives or terrorism-related materials, public security checkpoint operations to apprehend fleeing criminal suspects in vehicles, prevention of vehicle ramming attacks at entrances to critical venues, and mandatory vehicle passage control at prisons and border checkpoints. It fundamentally resolves the operational pain points of traditional fixed vehicle barriers being inflexible in deployment, warning-type roadblocks being unable to stop vehicles deliberately attempting to ram through, and large vehicle-mounted roadblocks being inconvenient to transport. It provides frontline law enforcement officers with "concealed camouflage to lure the target in, remote-controlled safe triggering, efficient deflation for controlled braking, and mobile rapid flexible deployment" tactical-level vehicle interdiction capability. It is a standardized police roadblock equipment certified by the Ministry of Public Security's GA/T 421-2003 Puncture-Deflation Type Roadblock standard.

Technical Principle

This equipment operates on the synergistic principles of mechatronic integrated wireless remote triggering and puncture-deflation braking. In standby mode, the device lies flat on the road surface in the form of a speed bump, with external dimensions of 650cm × 27cm × 5cm. Its appearance is highly similar to that of an ordinary road speed bump, so drivers approaching it do not become alerted or take emergency braking or evasive actions, ensuring that the target vehicle smoothly enters the interdiction zone at a normal driving speed. Internally, 216 high-strength hollow stainless steel deflation spikes are arrayed along the cross-section of the speed bump. Each spike is in a compressed, ready-to-fire state, uniformly locked by a linkage-type mechanical trigger mechanism that runs through the entire set of roadblocks.

Once the front or rear wheels of the target vehicle are completely within the roadblock zone, an operator at a safe distance (effective remote control range ≥150 meters) transmits an encrypted trigger signal via the wireless remote control. After verifying the signal integrity, the built-in receiving module controls the rated DC 12V electromechanical drive unit to instantaneously release the locking mechanism. All 216 spikes are simultaneously deployed under spring thrust. The spike tips, assisted by the contact pressure of the vehicle's tires on the ground, rapidly penetrate the tread rubber layer. Because the spikes feature a hollow structure, they create a continuously open deflation channel upon penetrating the tire. The compressed air inside the tire leaks out at a high rate over a period of seconds to tens of seconds, achieving non-explosive, non-destructive flexible and controlled braking—the vehicle stops not due to a collision or rollover, but because it loses mobility due to continuous tire deflation. This reliably achieves the goal of immobilization while minimizing the risk of injury to the vehicle occupants and surrounding personnel to the greatest extent possible.

The entire system is assembled from 36 modular roadblock panels connected by fasteners. Each panel is lightweight and easy to carry, allowing deployment or retrieval across the road width to be completed within a few minutes. The structural materials of the equipment are a combination of high-performance reinforced plastic and stainless steel. The entire unit has a maximum load capacity of 20 tons and can withstand repeated rolling by various types of small and medium-sized vehicles without structural deformation or mechanical failure. The remote control system features an anti-interference design with a response speed of ≤1 time/second, ensuring accurate instruction transmission and reliable action in complex electromagnetic environments. In standby mode, the surface of the equipment allows for the normal passage of vehicles and pedestrians without affecting the everyday function of the road, perfectly meeting the dual needs of law enforcement agencies for checkpoint equipment to be "non-disruptive to the public during peacetime, yet rapidly responsive during wartime."

Core Functions and Compliance Operational Value

Concealed Speed Bump Camouflage and Remote Wireless Triggering, Achieving the Tactical Surprise of "Luring the Target Deep and Interdicting Safely"
The device adopts an exterior design that is highly similar to ordinary road speed bumps, blending into the road environment in standby mode. The driver of the target vehicle, completely unaware, enters the interdiction zone at normal speed. This avoids the risk of traditional openly-displayed roadblocks causing the suspect vehicle to accelerate through the checkpoint, reverse and flee, or detour around it due to premature exposure. The operator, at a safe distance of 150 meters, instantly activates the spike deployment via the wireless remote control. The entire triggering sequence is completed within a response speed of ≤1 time/second, achieving interdiction within a window of opportunity when the target vehicle is completely unable to react. This tactical chain of "concealed camouflage—luring the target deep—remote triggering—rapid deflation" provides a non-lethal vehicle immobilization solution that conforms to the principle of tactical surprise for high-risk scenarios such as special police counter-terrorism interdiction of vehicles carrying explosives and police apprehension of fleeing suspects in vehicles. The operational mode and force application level fully align with the relevant provisions in the Operational Procedures for On-Site Suppression of Illegal and Criminal Acts by People's Police of Public Security Organs regarding the use of police equipment to suppress illegal and criminal acts.

216 Hollow Stainless Steel Deflation Spikes and the Flexible Braking Principle, Significantly Reducing the Risk of Collateral Damage While Maximizing Interdiction Effectiveness
The device is equipped with 216 high-strength hollow stainless steel spikes. The spike array is densely arranged, ensuring that regardless of the angle at which the target vehicle enters the roadblock zone, a sufficient number of spikes penetrate the front and rear tires. The spikes feature a hollow structural design, creating a continuously open deflation channel upon penetrating the tread rather than causing an explosive rupture. The air inside the tire leaks out at a controlled rate, causing the vehicle to gradually lose mobility over tens of seconds rather than going out of control instantly. This effectively reduces the collateral risks of the vehicle rolling over, crashing into roadside facilities, or injuring occupants due to a blowout. At the level of law enforcement ethics, this flexible braking principle provides technical support for the necessity and proportionality of forcible interdiction measures—while effectively achieving the law enforcement objective of stopping the vehicle, it minimizes the potential for bodily injury to suspects and the public to the lowest possible level, embodying the core philosophy of non-lethal law enforcement equipment design.

Modular Lightweight Structural Design, Supporting the Flexible Tactical Requirement of "Mobile Checkpoints and Flowing Defense"
The entire unit is composed of 36 quickly connectable roadblock panels, with a total deployed length of 650cm, covering a standard lane width. The total weight is no more than 25 kilograms, allowing a single person to complete all deployment or retrieval operations. No construction work, anchor bolts, or external power supply is required. An interdiction line can be formed within minutes of arriving at the checkpoint location, and quickly disassembled and stowed into a portable carrying bag upon departure. This highly mobile deployment characteristic allows the equipment to be flexibly deployed as needed in various dynamic law enforcement scenarios, such as temporary checkpoints at key intersections, mobile vehicle inspection points, and emergency security lines around major event venues. The checkpoint location can be adjusted in real time based on intelligence, truly achieving "mobile defense without leaving a trace." From the equipment level, this effectively supports the flexibility and stealth requirements for vehicle interdiction methods under dynamic duty models.

20-Ton Load Capacity and Public Security Industry Standard Certification, Guaranteeing the Long-Term Reliability and Standardization of Equipment in Harsh Law Enforcement Environments
The device is manufactured from a combination of high-performance reinforced plastic and stainless steel materials, with a robust structure. The entire unit has a maximum load capacity of 20 tons, capable of withstanding repeated rolling by various small and medium-sized passenger cars and light trucks without structural deformation or mechanical failure, meeting the durability requirements of high-frequency use and long-term deployment. The product strictly complies with the Ministry of Public Security's GA/T 421-2003 Puncture-Deflation Type Roadblock industry standard. This standard specifies clear testing methods and pass/fail criteria for the puncture performance, trigger reliability, load capacity, and safe usage conditions of deflation-type roadblocks, providing authoritative technical endorsement for the law enforcement compliance of the equipment, ensuring that the procured and used equipment meets the unified requirements for the standardized construction of police equipment nationwide.

Compliant Application Scenarios

Special Police Counter-Terrorism and Emergency Response Vehicle Interdiction Scenario
During counter-terrorism emergency response missions, when intelligence indicates that a suspected terrorist or explosives-laden vehicle may flee along a certain route or attempt to ram a critical facility, special police forces rapidly deploy this remote-controlled tire deflator at key intersections or bridge entrances. The device remains concealed in speed bump form on standby, without impeding the normal flow of social vehicles. Once the target vehicle has entered the roadblock zone and its identity is confirmed, the operator triggers the device remotely from a safe distance. The spikes instantly deploy and penetrate the tires. The vehicle is forced to a stop under the effect of flexible braking, and the follow-up assault team quickly approaches to execute control and apprehension. This tactical interdiction model achieves the effective stopping of high-risk suspect vehicles in a non-lethal, low-collateral-damage manner. The operational procedure strictly complies with the principle of proportionality in the use of force as stipulated in relevant counter-terrorism regulations.

Public Security Checkpoint Inspection and Apprehension of Fleeing Suspects in Vehicles Scenario
When public security organs set up road checkpoints or cordon off and apprehend criminal suspects fleeing in vehicles, investigators pre-deploy this equipment on potential escape routes or at the exit direction of the inspection point. When a suspect vehicle ignores commands to stop and forcibly rams the checkpoint, the operator remotely triggers the tire deflator. The vehicle's tires continuously deflate and lose mobility within seconds. The police then safely approach the vehicle to execute the arrest. The concealed nature of this equipment effectively prevents suspects from accelerating to ram through or abandoning the vehicle to flee upon spotting the roadblock prematurely, providing a critical tactical initiative for the arrest operation. The usage process complies with the statutory procedural requirements for establishing checkpoints and intercepting suspect vehicles by public security organs.

Vehicle Anti-Ramming Scenario at Entrances of Critical Venues and Major Events
At the vehicle entrance and exit channels of government organs, military installations, embassies and consulates, large event stadiums, and important conference venues, security forces deploy this equipment in a permanent or temporary manner. Under normal conditions, the device blends into the road surface in the form of a speed bump, without impeding the normal passage of authorized vehicles or the aesthetic image of the entrance. When a sudden incident occurs involving an unauthorized vehicle attempting to forcibly ram through the entrance, security personnel immediately trigger the tire deflator remotely. The suspicious vehicle is stopped at a safe distance outside the entrance, preventing it from rushing into the core security area and buying valuable time for subsequent EOD inspection and personnel control. This protective mechanism strictly conforms to the statutory obligation stipulated in the Anti-Terrorism Law requiring entities managing key targets to be equipped with effective security precautions.

Mandatory Vehicle Passage Control Scenario at Prisons and Border Checkpoints
At the AB gate vehicle passages of prisons and detention centers, as well as the entry/exit vehicle inspection passages of border checkpoints, this equipment serves as a mandatory physical interdiction measure used in conjunction with conventional inspection facilities. When a vehicle undergoing inspection shows signs of attempting to break through and escape within the passage, duty officers can remotely activate the tire deflator, quickly stopping the vehicle. This effectively prevents detainees from using vehicles to escape or smuggling contraband across the border. This application mode provides a supplementary interdiction means in addition to rising bollards and vehicle barrier arms for the security control of vehicle passages in correctional facilities and at border checkpoints. It meets the equipment configuration requirements of judicial administrative organs for the safety management of correctional facilities and border inspection authorities for entry/exit control.

Core Technical Parameters

In terms of core structure, the device has external dimensions of approximately 650cm × 27cm × 5cm in the deployed state. It is assembled from 36 modular roadblock panels connected by fasteners, with a total unit weight of ≤25 kilograms, making it convenient for single-person or two-person carry and rapid deployment. The tire deflation unit is configured with 216 hollow stainless steel deflation spikes arranged in an array, ensuring full coverage penetration and continuous deflation of the tires of any vehicle entering. For the remote control and electrical system, a mechatronic integrated wireless remote control device is employed, with an effective remote control distance of ≥150 meters and a remote control response speed of ≤1 time/second, featuring anti-interference capability. The operating voltage is rated DC 12V, with a normal operating voltage range of 11.5V to 13.8V. In terms of load-carrying performance, the entire unit has a maximum load capacity of 20 tons, capable of withstanding repeated rolling by various small and medium-sized vehicles. Regarding compliance, the product strictly meets the Ministry of Public Security's GA/T 421-2003 Puncture-Deflation Type Roadblock industry standard. The standard configuration includes one set of the remote-controlled tire deflator main unit (with built-in spikes and trigger mechanism), one wireless remote control (battery included), 36 roadblock connection panels, one dedicated power connection cable, and one portable carrying bag/case.

Compliant Field Application Cases

During the handling of a suspected terrorist-related vehicle ramming incident, a municipal special police detachment received a report from the command center that a sedan listed as a key surveillance target was heading towards the city outskirts along a main artery. The vehicle had previously forcibly broken through a checkpoint during an earlier inspection and fled, and the occupants might be carrying dangerous items. The special police interdiction team urgently deployed this remote-controlled tire deflator at the entrance ramp of a bridge that was the only route out of the city. It was concealed and blended into the road surface in speed bump form. After deployment, the normal passage of surrounding vehicles was unaffected. Several minutes later, the target vehicle entered the deployment area at normal speed. The operator confirmed that both the front and rear wheels of the vehicle were completely within the roadblock zone before triggering the system remotely. The spikes instantly penetrated the front and rear tires. After coasting for several tens of meters, the vehicle's speed decreased significantly and it finally came to a stop. The follow-up assault team, under safety protection, quickly approached and took control of the occupants. The entire interdiction process resulted in zero casualties and did not cause a prolonged interruption to bridge traffic. After the operation, the tire deflator was quickly disassembled and retrieved, and the road surface was restored to its original condition. In this operation, the concealed camouflage and remote triggering characteristics of the equipment played a crucial role in successfully stopping the high-risk suspect vehicle.

During the implementation of a security upgrade project for the AB gates of its subordinate prisons, a provincial prison administration bureau incorporated this remote-controlled tire deflator as a supplementary piece of equipment into the overall security plan as a mandatory physical interdiction measure for vehicle passages. One set was deployed on each of the inner and outer sides of the prison AB gate vehicle inspection passage. Under normal conditions, the equipment lies flat on the passage floor in speed bump form, without affecting the normal passage of vehicles entering and leaving the prison. When inmate labor vehicles or external supply vehicles undergo inspection procedures within the passage, the duty officer carries the wireless remote control. Should any abnormal situation be detected or a vehicle attempt to break through, the roadblock can be instantly triggered remotely to forcibly stop the vehicle. Since being put into service, the equipment has effectively enhanced the physical deterrence and substantive control capability over the AB gate vehicle passage. Its operational performance has been stable, with no accidental triggers or mechanical failures. Its full compliance with Ministry of Public Security industry standards has also provided a standardized equipment guarantee for the standardized construction of prison safety equipment.
