First of all, the hardness and sharpness of the road thorn should be up to the standard. The puncture thorn of the road stab barricade not only bears the pressure of the car, but also bears the impact force of the vehicle forward, so it is a great challenge to the hardness and toughness of the road thorn. One piece of fine steel casting stab will be more hardness than steel plate cutting and grinding steel, hardness also determines the sharpness. Only with the hardness of the road thorn, in sharp shape, the sharpness will be good. The whole type of fine steel casting has such conditions. Secondly, the hydraulic power plant should be placed underground (anti-collision, destruction, waterproof, corrosion protection). The hydraulic power device is the heart of the barbed road block. It must be installed in a concealed place (buried) to increase the difficulty of terrorist destruction and extend the time of destruction. Buried in the ground, put forward higher requirements for the water resistance and corrosion resistance of the device. It is suggested that the integral sealing oil pump and cylinder be adopted, and the waterproof grade is up to IP68, which can work normally under water for a long time. The whole frame is recommended to be hot-dip galvanized, which can prevent corrosion for more than 10 years.?installation of tyre killer. Again, a variety of control methods and use. If there is only one kind of control mode, then the control end became a terrorist destruction defense weakness, such as using remote control signal jammers, with terrorists can make remote failure; installation of tyre killer.if only by wire (control box), then the control box is damaged, thorn road barricade becomes a decoration. So the best is the coexistence of a variety of control mode: the control box is placed in the guard room desktop, for routine control; the control box located in the control room for remote monitoring and remote control operation; portable operation for emergency situations; in addition to the pedal, hidden, can be used for alternative is under the state of emergency. tyre killer.Finally, it is essential to operate the power off mode, once terrorists cut off or destroy the circuit, or temporary power outages, standby power supply to ensure that the device runs normally. There are also manual pressure relief devices, if the power is in the state of rising when the power, just in case the car needs to be released, you need to use manual pressure relief device. Tyre killer. is a very effective security facilities, at the same time, the technical indicators are also very high, must fully consider and reach the above basic requirements, in order to be qualified security tools.
