Qala

Kwangeminyaka yoo-1830s kamsinya nje emva kokuzalwa kwemoto yomphunga, abanye abantu bakhawula ukunika ivili lemoto ukuseta iinkuni kunye “neengoma” zerabha, ukuze iimoto ezinomphunga zikwazi ukuhamba kumhlaba othambileyo, kodwa ukusebenza komkhondo kwasekuqaleni kunye nesiphumo sokusebenzisa akulunganga, de kwangowe-1901 xa iLombard e-United States yavelisa isithuthi sokutsala samahlathi, yavelisa kuphela isiphumo esisebenzayo sokuqala. Kwiminyaka emithathu emva koko, injineli yaseCalifornia uHolt wasebenzisa uyilo lukaLombard ukuyila nokwakha i-“77″ yetrekta yomphunga.

Yayiyitrektara yokuqala elandelwayo emhlabeni. Ngomhla wama-24 kuNovemba ka-1904, itrektara yavavanywa okokuqala kwaye kamva yafakwa kwimveliso yobuninzi. Ngo-1906, inkampani yokuvelisa itrektara ye-Holt yakha i-petroli yokuqala ye-injini yokutshisa yangaphakathi ye-injini yokutshisa i-trawler, eyaqala imveliso enkulu kunyaka olandelayo, yayiyeyona mpumelelo yetrektara yelo xesha, kwaye yaba yi-prototype yetanki yokuqala yehlabathi eyaphuhliswa yiBritane kwiminyaka embalwa kamva. Ngomnyaka we-1915, iBritane yavelisa itanki ethi "Little Wanderer" ilandela iitrekta ze-American "Brock". Ngomnyaka we-1916, iitanki eziphuhliswe eFransi "Schnad" kunye ne "Saint-Chamonix" zazilandela iitrekta zaseMelika "Holt". Abarhubuluzi baye bangena kwimbali yamatanki phantse i-90 entwasahlobo nasekwindla ukuza kuthi ga ngoku, kwaye iingoma zanamhlanje, kungakhathaliseki ukuba zeziphi iifom zesakhiwo okanye izixhobo, ukusetyenzwa, njl., zihlala zityebisa indlu yobuncwane betanki, kwaye iingoma ziye zaphuhliswa zibe ngamatanki anokumelana novavanyo lwemfazwe.

Yakha

Iingoma ziintambo eziguquguqukayo eziqhutywa ngamavili asebenzayo ajikeleze amavili asebenzayo, amavili omthwalo, amavili okwenziwa kunye neepulleys ezithwala. Iingoma zenziwe ngezihlangu zomzila kunye nezikhonkwane zomzila. Izikhonkwane zengoma zidibanisa iingoma ukwenza ikhonkco lengoma. Iziphelo ezibini zesihlangu somzila zinomngxuma, zixutywe ngevili elisebenzayo, kwaye kukho amazinyo akhuthazayo phakathi, asetyenziselwa ukulungisa umzila kunye nokuthintela umzila ukuba ungawi xa itanki ijika okanye iqengqeleke, kwaye kukho i-anti-slip rib eqiniweyo (ebizwa ngokuba yipatheni) kwicala loqhagamshelwano lomhlaba ukuphucula ukomelela kunye nokuqina komkhondo wokubambelela emhlabeni.
