Hydraulic road blocks are specifically developed for access locations that are vulnerable to vehicle attack or have high security needs. Hydraulic road blockers are the only option and the most secure solutions when there is a threat of vehicle assault in addition to the control of vehicle access in high security applications. Despite the fact that the attack is from high-tonnage trucks travelling at fast speeds, the vehicle is unable to continue going due to damage to the front, wheels, and bottom of the vehicle.
The driving unit is hydraulic, however in the event of a power outage, the road blocker may be manually lowered or elevated using manual hand pumps. Every type of card reader, biometric readers such as fingerprint or hand shape, radio control, on/off key switch, and other devices may perform the raise/lower function with the aid of PLC controlled electronics. In addition, safety equipment such as dual vehicle safety loop detectors and red/green lights can be included in the system as options.
