I-Hydraulic shallow-buried flip plate road blocker, eyaziwa nangokuthi i-anti-terrorism wall noma i-road blocker, isebenzisa ukuphakamisa nokwehlisa i-hydraulic. Umsebenzi wayo oyinhloko ukuvimbela izimoto ezingagunyaziwe ukuthi zingangeni ngamandla, ngokusebenziseka okuphezulu, ukwethembeka, nokuphepha. Ifanele izindawo lapho indawo yomgwaqo ingenakumbiwa ngokujulile. Ngokwezidingo ezihlukene zesayithi kanye nekhasimende, inezinketho ezihlukahlukene zokucushwa futhi ingenziwa ngokwezifiso ukuze ihlangabezane nezidingo zokusebenza zamakhasimende ahlukahlukene.Ifakwe uhlelo lokukhululwa oluphuthumayo. Esimeni sokuphelelwa amandla noma ezinye izimo eziphuthumayo, singehliswa mathupha ukuze kuvulwe iphaseji yethrafikhi yemoto evamile.
