MDAB GENERAL INFORMATION
Optima MDAB crash rated manual drop arm barriers are designed especially for entrances where there is a threat of suicide vehicle attack or for the entrances that have high security requirements. This product is preferred especially at sites where there is no electricity. As the control of the manual drop arm barrier is by manpower, the vehicle traffic may slow down but from security point of view, manual drop arm barriers have the strength as the hydraulic driven barriers.
Even MDAB is a manual operated barrier; MDAB supplies crash resistance through strong foundation and design. Optima MDAB crash rated manual drop arm barriers are designed according to PAS68 parameters with the results of Finite Element Analysis.
