Optima Challenger Electromechanical Arm Barrier (B Series) is designed for high flow traffics. Compare to the standard parking barriers, Optima Challenger electromechanical barriers are suitable for harsh environments and intensive usage. With the help of a strong electric motor, the barrier can resist the hottest environmental conditions even it is used continuously. Another strong advantage of Optima barriers is a smooth operation by frequency controller which supplies a slow start/slow stop operation. This type of operation increases the mechanism usage of life significantly.
