Hydraulic Road Blockers in Pakistan
ASG Systems supplies, installs and maintains hydraulic road blockers for government, military, airports, banks, embassies and industrial sites across Pakistan, with surface-mounted, shallow and deep-mount models and emergency fast operation.
- Surface, shallow and deep-mount road blockers
- Emergency fast operation for high-threat sites
- Combined with barriers, bollards and access control
What is a hydraulic road blocker?
A road blocker, also called a wedge barrier, is a heavy steel plate that rises out of the road to physically stop a vehicle. When an authorised vehicle arrives, it lowers flat into the road so the vehicle can drive over it.
Unlike a boom barrier, which only controls traffic, a road blocker is built to stop a vehicle that tries to force its way in. That is why it is used at high-security entrances, usually together with a boom barrier for everyday traffic control.
A hydraulic power unit raises and lowers the plate, while a controller links it to access control, detection loops, traffic lights and an emergency button.

How a hydraulic road blocker works
The blocker stays up by default and lowers only for authorised vehicles.
Vehicle stops
The vehicle stops in front of the raised blocker and red light.
Identification
The guard, RFID, plate recognition or remote confirms the vehicle.
Blocker lowers
The hydraulic unit lowers the plate flat and the light turns green.
Blocker rises
After the vehicle passes, the blocker rises and the lane is sealed again.
Types of road blockers we supply
The right model depends on your threat level, ground conditions and traffic.

Safety and control features
Road blockers are powerful machines, so safety is designed in from the start.
- Vehicle detection loopsStop the blocker from rising under a vehicle and confirm when it has passed.
- Traffic lights and warning stripesMake the blocker clearly visible to drivers day and night.
- Manual hand pumpLowers the blocker during a power failure.
- Emergency fast operationRaises the blocker in seconds in an emergency.
- Access control integrationWorks with RFID, plate recognition, boom barriers, intercoms and CCTV.

Which vehicle security system do you need?
Each system does a different job. Many sites combine two or more for layered security.
| System | Main purpose | Security level | Best suited for |
|---|---|---|---|
| Boom barrier | Fast lane control for high traffic | Standard | Societies, car parks, offices, hospitals, toll plazas |
| Bollards | Block vehicles, let people walk through | Standard to high | Building fronts, plazas, malls, embassies, banks |
| Road blocker | Physically stop a vehicle at the gate | High | Government, military, airports, data centres |
| Tyre killer | One-way control that disables wrong-way vehicles | Medium to high | Exit-only lanes, compounds, depots |
| Sliding / swing gate | Closes the full opening, day and night | Medium | Homes, factories, warehouses |
| Intruder alarm | Detects people breaking in and raises alerts | Detection | Homes, shops, offices, warehouses |

Road blocker FAQs
What is the price of a hydraulic road blocker in Pakistan?
The price depends on the lane width, the security level, surface, shallow or deep mounting, emergency fast operation, access control and the civil work at your site. ASG Systems offers a free site survey and a detailed quotation for your entrance.
What is the difference between a road blocker and a boom barrier?
A boom barrier controls traffic with a lifting arm but cannot stop a vehicle that forces its way in. A road blocker is a heavy steel plate that physically stops the vehicle. Many sites use both together.
Does a road blocker work during a power failure?
Yes. Hydraulic road blockers include a manual hand pump to lower the plate, and they can be connected to backup power.
How long does a road blocker take to rise?
Standard models rise in a few seconds. Emergency fast operation models rise even faster when the emergency button is pressed.
Do road blockers need deep excavation?
Not always. Surface-mounted road blockers need no deep pit, while shallow and deep-mount models are set in the road for a flush finish and higher strength.
Where has ASG Systems installed road blockers?
Our road blocker projects include Allama Iqbal International Airport in Lahore and NDMA Headquarters in Islamabad.
