DoorKing’s auto-spike/barrier gate-operator system provides increased traffic lane control in applications where bollards or crash barriers are not practical. The system, which will disable a vehicle by flattening tires if an unauthorized exit occurs, can accommodate any traffic lane width by combining different lengths of tunnel sections and spike sections. The barrier gate operator and auto-spikes operate in synchronization so that the spikes are always in the up position when the barrier arm is down, and in the down position when the barrier arm is up. An optional stop/go traffic light and mounting post signal drivers when it is safe to proceed. DoorKing
