Tyre Killers
Tyre Killers
Engineered to eliminate wrong-way traffic at parking exits or to stop unauthorized entry into high-security zones, KRC Tyre Killer (Spike Barrier) Systems deliver absolute physical prevention. Available in mechanical surface-mounted or subterranean hydraulic options, our spike barriers feature heavy-gauge steel structures capable of withstanding heavy axle loads. In case of a forced breach, the hardened steel spikes pierce vehicle tyres instantly, bringing the vehicle to an immediate halt.

Mechanical tyre killers (MTK) lower their spikes purely through the weight of the vehicle passing over them — no electrical connection is needed. Electromechanical models (ETK) use a motor to move the spikes independently, enabling one-way or reverse-direction access control.
Yes. KRC tyre killer spikes and housings are manufactured to withstand high axle loads. The ETK Series uses 10 mm ST52 steel blades with anti-corrosion treatment.
The ETK-FM and MTK-FM flush-mounted models require concrete excavation. The ETK-SM and MTK-SM surface-mounted models bolt directly to the ground surface with no excavation needed — a major advantage for temporary installations or rented sites.
Yes. During unauthorised entry the spikes pierce the vehicle's tyres, bringing it to a halt within a few metres. During authorised passage, the vehicle's weight pushes the spikes down and they return to the raised position automatically — no tyre damage occurs.
Military facilities, government buildings, police stations, embassies, airports and car parks are the primary applications. They provide effective control wherever one-directional vehicle passage is required.
