The electric barrier gate can raise and lower the gate arm alone through wireless remote control, or it can be automatically managed through the parking lot management system (i.e. IC card swiping management system). Vehicles are released upon entry after collecting the card, and are automatically released after leaving the parking lot after collecting the parking fee. The barrier gate movement is an important component of the barrier gate, and its function is to control the rise and fall of the gate arm.
