Ama-bollard ayisici esibalulekile sengqalasizinda yasemadolobheni yanamuhla, enikeza izinzuzo eziningi zokuphepha nokuphepha. Kusukela ekuvimbeleni ukufinyelela kwezimoto ezindaweni ezihamba ngezinyawo kuphela kuya ekuvikeleni izakhiwo ekulimaleni ngengozi, ama-bollard adlala indima ebalulekile ekuqinisekiseni ukuphepha komphakathi.

Amabhodi okuphakamisa okuzenzakalelayoyizingodo ezinenjini ezingaphakanyiswa futhi zehliswe kude kusetshenziswa uhlelo lokulawula. Lezi zingodo zivame ukusetshenziswa ezindaweni eziphephile kakhulu njengezakhiwo zikahulumeni, izikhumulo zezindiza, kanye namanxusa. Zinikeza isithiyo esisebenzayo sokuvimbela ukufinyelela okungagunyaziwe futhi zingenziwa ngezifiso ukuze zihlangabezane nezidingo ezithile zokuphepha.
Ama-bollard okuphakamisa azenzakalelayo afana nama-bollard okuphakamisa azenzakalelayo, kodwa adinga ukungenelela ngesandla ukuze akhushulwe futhi ehliswe. Lawa ma-bollard avame ukusetshenziswa ezindaweni zokupaka, ezindaweni zabahamba ngezinyawo, nakwezinye izindawo lapho ukufinyelela kwezimoto kudingeka kulawulwe khona.
Amabhodi aqinile, njengoba igama lisikisela, azishukumi futhi zinikeza isithiyo esihlala njalo ekungeneni kwezimoto. Zivame ukusetshenziswa ukuvikela izakhiwo, izindawo zomphakathi, nezinye izindawo ezibucayi emonakalweni wengozi noma ohlosiwe obangelwa yizimoto.
Amabhodi agoqekayoNgakolunye uhlangothi, ziyagoqeka futhi zingagoqeka kalula uma zingasetshenziswa. Lawa ma-bollard avame ukusetshenziswa ezindaweni lapho kudingeka khona ukugcinwa kokufinyelela kwabahamba ngezinyawo ngenkathi kuvumela ukufinyelela kwezimoto ukuze kuthunyelwe noma kuhlinzekwe ngezinsizakalo eziphuthumayo.

Ngokukhetha uhlobo olufanele lwe-bollard yesicelo esithile, abanikazi bezindawo nabahleli bedolobha bangaqinisekisa ukuthi bahlinzeka ngokuvikelwa okudingekayo ekufinyeleleni okungagunyaziwe, ekulimaleni ngengozi, kanye nezinye izingozi ezingaba khona.
Ngiyacelaubuze ngathiuma unemibuzo mayelana nemikhiqizo yethu.
