Overview

Passive/Spring Loaded Spikes

For lower security applications, surface mounted passive 1-way spikes can be installed which incorporate spring loaded spikes that are depressed and lowered by the movement and weight of the car as it passes in the correct direction. Any attempt to pass over the spikes in the wrong direction will result in multiple tire punctures. The spikes can incorporate an optional screw mechanism to allow them to be manually locked in the down position to temporarily enable vehicles to pass in the wrong direction.

These spikes are cost effective way of securing exit lanes where the complexity and extra investment in gates or barriers cannot be justified. This barrier is often used at the exit to parking lots, factories, malls and other areas of heavy traffic. It is particularly effective where high rates of exit traffic are found since it has a minimal effect on traffic flows.
