The 3-Gate AisleCop® Dual Pedestrian & Single Vehicle Gate System helps control vehicular and pedestrian traffic where their patterns cross. Triggered by motion detectors, two pedestrian gates and a vehicle boom arm open and close based on preferences you specify, whether you want vehicles or pedestrians to have priority for a particular crossing. In either case, pedestrian gates close when a forklift is detected and boom arm lowers to warn vehicles of pedestrians crossing the intersection. To further enhance pedestrian safety, flashing lights and an audible alarm are triggered when the system is activated. Custom control and sensor configurations are available upon request. Guardrail sold separately.
