Hydraulic Drop Arm Barrier

General Information

Optima HDAB hydraulic drop arm barriers are designed especially for entrances where there is a threat of suicide vehicle attack, or for the entrances that have high security requirements. If there is a threat of vehicle attack in addition to the control of vehicle access in high security applications, hydraulic drop arm barriers are one of the best and most secure solutions. Even though the attack is from high tonnage vehicles with high speeds, it is not possible for the vehicle to keep on moving forward anymore beyond the arm of the barrier.

The drive unit is hydraulic, but in case of power failure barrier can be closed or opened manually with the help of hand pumps. With the help of PLC controlled electronics, open/close function can be achieved by every kind of card readers, biometric readers like fingerprint or hand shape, radio control, on/off key switch etc. Besides, safety accessories like photocells, inductive loop detectors, flashing lights or red/green lights can be integrated to the system.
