Tyre killer is also called traffic spikes, which is a kind of tirebreaking road blocker driven by a hydraulic power device, remote control, or wire control. The tyre killer is composed of a highstrength blocking section and an auxiliary hard stab. It is mainly used to intercept vehicles with malicious collisions. The front collision of the highstrength blocking section blocks the entry of vehicles, and the auxiliary hard stab pierces into the tire. The air in the tire is released quickly, and the vehicle cannot move forward.

When the vehicle rushes through the roadblock machine at a high speed, the impact force of the vehicle will deform and damage the front of the vehicle, and the pressure of the wheel will make the stainless steel stab on the roadblock penetrate along the moving direction of the wheel, so as to effectively intercept illegal vehicles.

The stab of the tyre killer is relatively sharp. After the vehicle tire is rolled, it will be pierced in 0.5 seconds, and the gas in the tire will be vented through the vent hole, so that the vehicle cannot move forward. Therefore, it is a necessary antiterrorism road blocker in some key security places.

The hydraulic tyre killer is normally closed during operation, that is, it is raised during security operations to prevent any vehicle from passing. When the releasable vehicle wants to pass, the spike can be dropped through the manual control of the security personnel, and the vehicle can pass safely.

The tyre killer can be lifted and lowered by remote control and a wire control switch. At the same time, it can also be linked with the HD camera set in front of the inspection station, receive the early warning signal, and the tyre killer will automatically rise to block suspicious vehicles. In addition, hydraulic traffic spikes can also be linked with multiple systems such as unique underbody scanning and speed detection.
