Road blockers are 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 the control 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. Madoors road blockers are designed to K12 standards. Finite element model analyses 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 time is 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 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 traffic lights can be integrated to the system very easily. Typical weight of a road blocker is 2-2.5 tons (depending on road blocker type). anti terrorism barrier systems
MAdoorS mainly product range includes Road Blockers, Rising Bollards, Barriers, Turnstiles, Tyre Killers, Sliding Gates & Operators and according to meet engineering specifications these products are supplied with different performing systems; Hydraulic, Pneumatic, PLC Controlled Electromechanical and Manual road blcoker barrier Systems are available.
Electro-hydraulically power operated, our Blocking Bollards come in single or multiple units with a common drive unit. The standard blocking height above surface level ranges between 500 mm to 850 mm. Aesthetically designed in different shapes and colors, this range of bollards is ideal for pedestrian zones in the city, fuel pumps as well as for security purposes in front of important buildings
Madoors systems retractable security bollard is an automatic product that provides exceptional flexibility in appearance and functionality. This automatic bollard is designed for access control for building entrances such as hotels, event centers, golf clubs, exhibition centers and town centers.
MADOORS hydraulic rising bollards are designed for high security vehicle entrances, army, industrial, governmental and commercial buildings or streets which are closed to vehicle traffic between certain hours of the day. Both "High Security" and "Commercial" type MADOORS Hydraulic Rising Bollards have the same strength, whereas "Commercial" bollards are shorter than the "High Security" ones. The thickness of the bollard, the underground construction, the self-lubricating sealing and guide ring made of special plastic types, hydraulic piston, flange thicknesses and diameters, hydraulic connections, installation and drainage procedures etc. are all the same. These units are designed to K12 standards. Finite element analysis can be supplied upon request. Typical raise/lower time is 3 seconds but it is possible to design the system to raise/lower in 1.5 seconds.
