A fast boom barrier typically refers to a gate or barrier system designed to quickly open and close to control vehicular access to a certain area, such as parking lots, toll booths, or restricted zones. These barriers often employ hydraulic or electromechanical mechanisms for swift operation. They're commonly used in places where rapid access control is essential, like busy commercial areas or high-security facilities. The speed of operation is crucial for efficiency and safety, especially in areas with heavy traffic flow. https://www.novusapl.com/Ultrafast-Boom-Barrier-NS-BS7-P416.php
