1. Product characteristics:
According to the standard requirements of GA/T421-2003 Puncture and Exhaust Road Barrier, this product has the characteristics of pre-assembly, recycling, free expansion, safety and effectiveness, large road coverage, strong adaptability, light weight, portable and easy to use. It is the preferred equipment for intercepting vehicles.
II. Working Principle:
When the wheel touches the plastic roadblock, because of the driving pressure, the wheel will press the steel nail on the plastic roadblock, and the steel nail in the rubber sleeve will penetrate the tire along the moving direction. The deflated steel nail is separated from the roadblock. The wheels continue to rotate, making the alloy steel nails on the tire more thorny and deeper. The gas in the tire leaks out from the hole in the alloy steel nail. Generally, four to six steel nails will be pierced into the tire, and all the gas will be released in less than 20 seconds. To achieve the purpose of effectively intercepting vehicles.
