Portable Road Blocks

Spike Road Block provides effective Road Blockage against force full entry of vehicle at Vital Defence Installation / Units and also at very high security zones / buildings like Parliament House, President House, Prime Minister Residence, Embassies, Airports and Vital security establishments. 
65mm of strong hardened and sharp triangular spikes are pulled out manually. If attempted to drive through at any speed, its spikes are specially designed to penetrate into the vehicle tyre, and release air within the tyre quickly yet safely, causing the vehicle to stop. The time taken for these spikes to spread on the road is not more than 5 seconds. The deployment of Spike Road Block is possible by one man. 
The entire spike Road Block is fitted and installed in such a manner that no digging of road is required for its installation. In operation, the spike assembly is deployed from its case across the road. Vehicle tyres passing over the spikes are punctured by the sharp finned triangular spikes, which act as quick release air valve.
