Hydraulic rising Bollards are designed for high security vehicle enterances,industrial,government building application etc.
Bollards are raised to the is full lengths (60-90 cm) in 1.5 to 12 seconds depending on the requirements.
These units are designed to minimum K12 standards, by finite element analysis. For example any vehicle which weights 3620 kg and is moving 108 km/hr, will definitely be stopped and destroyed when used in groups.
Hydraulic Road Blocker
Road blockers are designed especially for entrance points which have a threat of vehicle attack or for the ones that have high security requirements. Even though the attack is from high tonnage vehicles with high speeds, it’s not possible for the vehicle to keep on moving because of the damage given to front, wheels and the bottom of the vehicle.
Drive unit is hydraulic, but in case of power failure road blocker can be lowered or lifted manually with the help of manual hand pumps and valves. Typical raise/lower time is 3 seconds. With the help of PLC controlled electronics, raise/lower function can be achieved by every kind of card readers, biometric readers like fingerprint or hand shape, on/off key switch etc.
