Road Blockers and Tyre Killers | Automatic Systems

Road Blockers and Tyre Killers play a crucial role in hostile vehicle mitigation (HVM) by preventing unauthorized vehicles from accessing high-security areas. These barriers are essential for blocking roadways to stop vehicle-based attacks. They can be installed by excavating the ground for a shallow foundation or even surface-mounted, depending on the requirements. These barriers can be manually or automatically controlled with hydraulic raising and lowering mechanisms. They are often crash-rated and certified to reliably stop and destroy vehicles during an attack. Installed in locations like military areas, embassies, and government offices, these blockers also come in the form of spike strips or tire killers that allow vehicles to exit while preventing unauthorized entry.

Road Blockers Overview

Similar to the initial barriers, Road Blockers are heavy-duty, anti-terrorist solutions designed for high-sensitive areas with strict vehicle access restrictions. Road blockers can be surface mounted or installed by excavating the ground. With both manual and automatic hydraulic operations, these blockers are crash-rated for stopping vehicles effectively. Besides high-security areas, other barriers like spike strips or tire killers serve to allow vehicles to exit restricted zones while preventing unauthorized entries.

What is a Road Blocker?

Road blocker, also known as anti-terrorist roadblocker, street blockers, and anti-ram barriers, is used to control or restrict vehicle access to particular areas. Designed to withstand high-impact collisions, they serve as an effective deterrent against vehicle-based attacks.

Road blockers are commonly installed at entry and exit points of high-security facilities such as:

• Government buildings
• Embassies
• Military bases
• Airports
• Prisons
• Industrial sites

Unlike ordinary roadblocks made of plastic or concrete, road blockers are constructed from steel. They can be raised or lowered into position using hydraulic or pneumatic systems and are controlled electronically by methods like remote control, key-card access, or a central control room. Some models also feature additional deterrent systems like warning lights and alarms to prevent unauthorized access and alert security personnel to intrusions.

Components of a Road Blocker

Road blockers, also known as rising kerbs, consist of several key components designed to block vehicular access:

• Hydraulic Power Unit (HPU): Comprising a hydraulic pump, oil reservoir, and control valves, the HPU is key to the operation.
• Barrier Segment: Made of high-strength steel, this is the physical part that creates the barrier.
• PLC Controller: Typically located in a security booth, this component remotely controls the road blocker.
• LED Lights: These serve as warning signals and are located on the top of the barrier segment.
• Safety Features: Including safety pressure switches, emergency stop buttons, and additional barriers to ensuring smooth and safe operation.

How Does a Road Blocker Work?

A road blocker is generally composed of three parts: the main frame, hydraulic transmission device, and an automatic inspection and control device. Constructed from welded thick plates and channel steel, the road blocker structure is designed to be robust and highly resistive to collisions. Once installed on a driveway, it restricts vehicle traffic. The hydraulic system drives the expansion and contraction of the oil cylinder, allowing the blocker to lift quickly. Additionally, remote control switches, leakage protection, and parameter-setting panels can be integrated for enhanced functionality and safety.

Factors to Consider Before Buying a Road Blocker

When purchasing road blockers, the following factors should be carefully evaluated to ensure they meet your specific requirements:

Design Considerations:

• Load-bearing capacity: Ensure the structure doesn’t deform over time.
• Durability: Consider fatigue lifting resistance and the design quality between components.
• Material: High-strength profiles are recommended for long-term use without deformation.

Oil Cylinder:

• Material and build quality, including a thick rod diameter and high-strength alloy construction.
• Imported oil seals for better sealing and minimal risk of leakage.
• Buffer devices to ensure smooth and quiet operation.
• Anti-freeze heating devices for cold regions.
• Fixed protective devices for the oil pipes and wiring.

Add-ons:

• Automatic switching for dual oil circuits.
• Maintenance features designed to avoid removing the barricade panel.
• Backup battery for uninterrupted operation.
• Supporting voice and warning lights for enhanced safety.

System Integration:

• Network connectivity and remote control capabilities via integrated platform management.
• Compatibility with other security systems and vehicle detection systems.

Additional factors include:

• Purpose: Determine if the road blocker is for vehicle access prevention in high-security areas or general traffic control.
• Size: Ensure the dimensions match the size of vehicles that will be using the entry point.
• Strength and Durability: Assess their ability to withstand high-impact collisions and harsh weather conditions.
• Control Options: Decide between manual and automatic control, depending on security requirements.
• Maintenance: Evaluate ease of maintenance and potential downtime.
• Cost: Ensure the road blockers are affordable and offer good value, meeting your facility’s specific needs.
• Local Regulations: Check for size restrictions, safety requirements, and installation guidelines.

How to Install Street Blockers

Ensure all tools and equipment are ready before starting the installation process of a hydraulic street blocker. The necessary equipment includes screwdrivers, wrenches, a hydraulic pump unit, high-pressure hydraulic hoses, a concrete drill, concrete screws, bolts, nuts, gravel, sand, and concrete mix.

Follow these steps for installation:

1. Determine the placement location with enough clearance and stable foundation.
2. Prepare a large, deep hole using a concrete drill.
3. Insert the street blocker and fill the area with gravel and sand, compacting it evenly.
4. Connect the hydraulic hoses to the unit, ensuring no kinks or twists.
5. Position the street blocker correctly above the hole.
6. Secure it with concrete screws, bolts, and nuts.
7. Connect the wiring from the hydraulic unit to the control panel as per manufacturer instructions.
8. Mix the concrete and fill the space around the blocker, ensuring it’s level and free of air pockets.
9. Allow the concrete to dry as recommended.
10. Test the street blocker to ensure proper functionality and clean the area thoroughly post-installation.
