Ukwethulwa kwakamuva kwesinye sesitayela esisha sokuphakamisa i-bollard, kungafinyelela uhlobo oluvulekile noluvaliwe lokuphakamisa inzuzo.
I-HVM Bollard amabholadi aklanywe futhi ahlolelwa ukuphahlazeka ukuze kuncishiswe izimoto ezinobutha. Lawa ma-bollards afakwe ukuvikela zonke izingosi ekuhlaselweni okungaba khona, noma ngabe ingqalasizinda kazwelonke ebalulekile noma izikhungo zasemadolobheni ezimatasa.
Ama-bollards e-HVM aklanywe futhi aklanywa ukuze alulaze izimoto ezinosayizi othile nesivinini futhi azohlolwa ukuphahlazeka ukuze ahlangabezane nale mfuneko. Kunamazinga amaningi amisiwe okulinganisa imikhiqizo ye-HVM, okuhlanganisa i-BSI PAS 68 (UK), IWA 14-1 (yamazwe ngamazwe) kanye ne-ASTM F2656/F2656M (US).
Nge-Vehicle Dynamics Assessment, ngokuvamile kungenzeka ukunquma usayizi nesivinini semoto edinga ukuncishiswa. Lokhu ngokuvamile kwenziwa Umeluleki Wokuphepha Wokulwa Nobuphekula (CTA) noma unjiniyela wezokuphepha oqeqeshiwe. Ama-bollards ethu e-HVM angaba nesisindo esingafika ku-1,500 kg ku-32 km/h (20 mph) kanye no-30,000 kg ngo-80 km/h (50 mph).
Ama-bollard e-HVM angabhekisela kunoma yiluphi uhlobo lwe-bollard eklanyelwe i-HVM, kungakhathaliseki ukuthi igxilile, igxunyekwe kancane, i-othomathikhi, ehoxiswayo noma ekhiphekayo. Ingasetshenziswa nakweminye imikhiqizo yokuhlola ukuphahlazeka njengezithiyo, imigoqo noma ucingo olucingo.
Siyakwamukela ukuxhumana nathi ukuze uthole imininingwane eyengeziwe
