The stainless steel manual tire breaker has the characteristics of pre-assembly, recycling, free expansion and contraction, safe and effective, large road coverage, strong adaptability, light weight, portable and convenient use. It is the preferred equipment for road traffic control.

  When the wheel touches the plastic roadblock, the pressure during driving will make the wheel press the steel needle on the plastic roadblock, and the steel needle in the rubber sleeve will pierce the tire with the direction of movement. Pneumatic tires will separate the steel needle from the roadblock. The wheel continues to rotate, making the steel needle on the tire pierce deeper and deeper. The gas in the tire leaks from the inner hole of the steel needle. Generally, four to six steel needles are pierced into the tire, and all the gas is released within 30 seconds. To achieve the purpose of effectively stopping the vehicle.
