Uma kukhulunywa ngokuzivikela ezimweni zezulu, zimbalwa izinto ezintsha eziye zahlala isikhathi eside njengesambulela. Sekungamakhulu eminyaka, lesi sixhobo esithobekile sisivikele emvuleni, eqhweni naselangeni, sinikeza indawo yokuphephela emizimbeni yemvelo. Kodwa ngemuva kokulula kwesambulela kulele umhlaba othakazelisayo wobunjiniyela nokuklama, ikakhulukazi uma kukhulunywa ngohlaka. Kulesi sihloko, sizohlola ubuciko bokuklama ozimele besambulela eziguquguqukayo, ubuchwepheshe obungemuva kwazo, kanye nomthelela ezinawo ekuphileni kwethu kwansuku zonke.
Ukuvela Kwamafreyimu Ezambulela
Ama-umbrella anomlando omude futhi onezindaba, aqala emuva ezinkulungwaneni zeminyaka empucukweni yasendulo efana neMesopotamia, iGibhithe, neShayina. Kodwa-ke, kwaze kwaba ngekhulu le-18 lapho isambulela sesimanje esigoqekayo, njengoba sisazi namuhla, saqala khona ukwakheka. Ukuthuthukiswa kwamafreyimu esambulela sekuhambe ibanga elide kusukela ngaleso sikhathi, kusukela ezakhiweni eziqinile nezinzima kuya eziklanyweni ezilula neziguquguqukayo.
Umgomo oyinhloko wanoma yiluphi uhlaka lwesambulela ukusekela uphahla nokulugcina luqinile, lunikeze isivikelo esiqinile esimweni sezulu. Kodwa-ke, ukuguquguquka kuye kwaba yinto ebaluleke kakhulu ekwakhiweni kwesambulela, ikakhulukazi njengoba sibhekene nezimo zezulu ezingalindelekile kanye nemimoya enamandla. Amafreyimu esambulela endabuko enziwe ngokhuni noma ngensimbi ayevame ukungabi namandla okugoba nokugoba, okwenza abe sengozini yokulimala emimoyeni enamandla noma emvuleni enkulu.
Izinto Ezibalulekile
Esinye sezici ezibalulekile ekuklameni ozimele besambulela eziguquguqukayo ukukhetha izinto zokwakha. Izambulela zesimanje zivame ukusebenzisa izinto ezifana ne-fiberglass, i-aluminium, ne-carbon fiber kumafreyimu azo. Lezi zinto zinikeza inhlanganisela efanelekile yamandla nokuguquguquka.
I-fiberglass, isibonelo, iyindlela ethandwayo ngenxa yokukhanya kwayo kanye nokuguquguquka okumangalisayo. Uma icindezelwa, i-fiberglass ingagoba futhi imunce amandla ngaphandle kokuphuka, okwenza kube ukukhetha okuhle kakhulu kwezimbambo zesambulela. I-aluminium kanye ne-carbon fiber nazo ziyaziswa ngezakhiwo zazo ezilula kanye nekhono lokubekezelela ukugoba ngaphandle kokuguquka unomphela.
