Revolving barriers are used to select passage in areas with high intensity of people flow. The barriers used to control the passage are: three-way swing barrier or tripod (one-way, two-way, with integrated access control), low revolving barriers, high revolving barriers with motorized wing, mechanical swing barrier, safety door and ramp. They are distinguished by mechanical construction, design, and electronic control, as well as purpose (public transport, sports halls, stadiums, etc.). They can be motorized (after the signal to open the barrier and the initial movement of the barrier, the motor takes over the rotation and speeds up the passage), or mechanical (rotation is performed by the person passing through, and the barrier is released – it allows the rotation in appropriate direction). In the event of an emergency (natural disaster, fire…) it is necessary to free up the evacuation routes, and the lower barriers can be made with a drop arm function (automatic lowering at the signal danger or power failure), or by releasing the rotation in both directions – same as full height barriers. Structurally, we distinguish low revolving pedestrian barriers that are mainly used in business facilities and are in public use – fairs, transportation (metro, railroad, tram, bus…), toilet payment collection…Passages for disabled persons are created in a way that they use low revolving barriers, or doors with adequate width. High revolving barriers (typically about 220 cm) are used with a higher degree of safety and/or when resistance to vandalism is needed. Typical example of the use of full height barriers can be seen at soccer stadium and facilities and plants where it is difficult to control the skipping of lower barriers.
