The hydraulic road blocker is one of the most reliable modern technologies used for vehicle access control. Designed for areas requiring maximum security—such as protection against vehicle-based suicide attacks—it features a hydraulic-driven structure capable of stopping vehicles regardless of their weight or build by damaging the undercarriage upon high-speed impact.

Drive System
Equipped with a hydraulic actuation system that is activated via an electronic control board. It is compatible with all types of access control systems, including push buttons, remote controllers, card readers, fingerprint scanners, etc.

Optional Accessories
Red-green traffic lights, strobe lights, sirens, and other security accessories can be integrated. In the event of a power outage, a manual pump can be optionally used for operation.

Operating Speed
The standard raise/lower time is 3–4 seconds, with special production available for speeds as low as 1 second upon request.

Set Contents

• 1 Hydraulic road blocker (4 meters)

• 1 Hydraulic control cabinet

• 1 Wired remote button
  (Traffic lights, poles, and strobes are offered as optional components.)

Operating Principle
Pressing the raise button lifts the road blocker to block vehicle passage. Pressing the lower button retracts it, allowing vehicles to pass.

Advanced Security Features

• Emergency Raise Button: Can be added for immediate lifting during emergency situations.

• Loop Detector System:

  • Entry Loop: Detects the approaching vehicle and lowers the blocker to permit access.

  • Exit Loop: Detects when the vehicle has exited and raises the blocker accordingly.

  • Safety Loop: Prevents the blocker from raising if a vehicle is still on it, even if the raise button is pressed—preventing damage to the vehicle.

Applications
Thanks to its reliable operation and strong security features, the YK 40 4m hydraulic road blocker is ideal for use in military bases, government buildings, embassies, prisons, and all public or private institutions that require high-level security control.
