Pneumatic Rising Roadblockers

Being a very reliable alternative to the hydraulic roadblockers, pneumatic roadblockers are an efficient way of solution if there is a threat of vehicle attack in addition to the control of vehicle access in high security applications. As the construction is completely the same with the hydraulic rising roadblockers, the strength of the construction is the same. The number of pistons used per roadblocker increases due to the low pressure achived in pneumatic systems. Besides, the piston diameters are larger when compared to hydraulic systems because of the same reason. Even though the attack is from high tonnage vehicles with high speeds, it is not possible for the vehicle to move any further. In standard, the constructive design is made to stop any vehicle with the impact load of 7.5 tons of weight, moving with 60 miles per hour. But Our designs according to customer requirements. Drive is pneumatic, therefore in case of power failure roadblocker can be lowered or lifted a few more times with the help of the pressure already in the high pressure tank. Typical raise/lower time is 3 seconds, but it is possible to design the system to raise/lower in 1.5 seconds. This is one of the main advantages of pneumatic systems over hydraulics, it is faster. The other main advantage of the pneumatic systems over hydraulics is the flexibility which enables any number of roadblockers at the same site with distances to each other, driven from one compression and power center.
