Ngokubaluleka kwayo njengokubanzi nokuzimisela kwezinto eziphakathi zokwakha izilayini zokuphambuka ngaphandle kwezindawo zokugcina isithuthi, i-u bolt iyathengiswa ngu-Hebei Heiniu ngokusebenzisa ukufaka emthwakathini ngokuphelele nokuhlinzekwa kokungafanele kusukela ekuthinteni amandla okusebenza okukhulu nokuphansi kwemizimbi engamandla yomhlaba. Izilayini zethu ze-u bolt ziyathengiswa ngamaphuzu amaningi wezilayini ezikhulu, zihlanganiswa ngokuphelele kanye nezithembiso kumashishini wethu wezilayini nokusebenza kwezilayini, futhi ziqondwa ngokuphelele ngezilayini zokuhlinzekwa ngokuphelele kumashishini wethu wokuhlinzekwa kokungafanele ukuze zikhubaze ukungafanele kwezilayini nokungafanele kwezilayini. Iyadizainiwe ukusebenza kwezinye izinkulungwane zokugcina izipholo kuma-crossarms, ukugcina izihlangothi zokugcina, noma ukugcina izilayini, futhi ngalokho u-u bolt uyadizainiwe ukuze uphinde uphindele umgcineli wokugcina okungafanele kanye nokungafanele kwezilayini, futhi uyakhanyelwa ngokuphelele ngokuphelele kwezifundo zokuphatha izilayini, amandla okuphefumula, kanye nokuphatha kwezithembiso. Sisiza ngokuphelele kwezinhlobo zezinga zika-u bolt kanye nezinhlobo, zibonisa ukuthi sithenga izilayini zonke, futhi itimu yethu yesayensi itholakala ukuze isize ukuchaza i-u bolt eyodwa yokugcina okuyidingekileyo kulezi zinhlobo zokugcina kwezilayini noma kwezilayini zokuphambuka, ukuze sibone ukuthi ukugcina kuyasebenza kanye nokudala ngokuphelele.
