HYDRAULIC RISING ROAD BLOCKERS

Hydraulic Rising Road Blockers
General Description
ISO 9001: 2008 EN ISO 14001: 2004

Road blockersare designed especially for entrance points which have a threat of vehicle attack or for the ones that have high security requirements. If there is a threat of vehicle attack in addition to thecontrol of vehicle access in high security applications, hydraulic road blockers are the unique solution and the most secure systems. 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. Optima road blockers are designed to K12 standards. Finite element modelanalyses are available upon request. Drive unit is electro-hydraulic, but in case of power failure road blocker can be lowered or lifted manually with the help of hand pump. Typical raise/lower timeis 3 seconds. In case of emergency, raise/lower time can be as low as 1.5 seconds. With the help of PLC (programmable logic control), raise/lower function can be achieved by every kind of cardreaders, 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 trafficlights can be integrated to the system very easily. Typical weight of a road blocker is 2-2.5 tons (depending on road blocker type). STEEL CONSTRUCTION Main mechanical elements forming the constructionare heavy duty 12 mm top plate and the frame consisting of 100*100 box, 200*75mm U and 100mm I beams. This sophisticated mechanical design enables the road blocker to withstand 60tons of axle loads,besides, in case of crash, linkage bars transmit the impact directly to the foundation, therefore help to protect the steel structure. Cushioned cylinders power the road blocker up as they pivot on...
