Particular sites require a high level of vehicular access control, such as government buildings, prisons, airports, embassies, industrial sites where valuable or chemicals are stored. Roadblockers are surface mounted or concealed in the roadway, with axle load capacities of up to 20 tonne. During operation, they are fast, mechanically locked in the "up" or "down" positions and tamperproof.
