Qala

Kudala ngeminyaka yawo-1830s ngemva nje kokuzalwa kwemoto yesitimu, abanye abantu bakhulelwa ukunikeza isondo lemoto isethi yokhuni kanye “namathrekhi” enjoloba, ukuze izimoto ezisindayo zikwazi ukuhamba endaweni ethambile, kodwa ukusebenza kwethrekhi yakuqala nokusetshenziswa akukuhle, kwaze kwaba ngu-1901 lapho iLombard e-United States isungula imoto edonsayo yamahlathi, yasungula ithrekhi yokuqala enomphumela omuhle kuphela. Eminyakeni emithathu kamuva, unjiniyela wase-California u-Holt wasebenzisa okusungulwe yi-Lombard ukuze adizayine futhi akhe “77″ ugandaganda wesitimu.

Bekuwugandaganda wokuqala olandelwa ngomkhondo emhlabeni. NgoNovemba 24, 1904, ugandaganda wenza izivivinyo zokuqala futhi kamuva wafakwa ekukhiqizeni ngobuningi. Ngo-1906, inkampani ekhiqiza ugandaganda kaHolt yakha ugandaganda wokuqala emhlabeni kaphethiloli ovuthayo wangaphakathi osebenza ngamandla enjini, owaqala ukukhiqizwa ngobuningi ngonyaka olandelayo, waba ugandaganda ophumelele kakhulu wangaleso sikhathi, futhi waba umfuziselo wethangi lokuqala emhlabeni elakhiwa amaNgisi eminyakeni embalwa kamuva. Ngo-1915, abaseBrithani basungula ithangi elithi "Little Wanderer" balandela amathrekhi we-American "Brock" ugandaganda.

Yakha

Amathrekhi ngamaketango aguquguqukayo ashayelwa amasondo asebenzayo azungeza amasondo asebenzayo, amasondo okulayisha, amasondo okungenisa kanye nama-pulleys okuthwala. Amathrekhi akhiwe izicathulo zethrekhi nezikhonkwane zethrekhi. Izikhonkwane zethrekhi zixhuma amathrekhi ukuze zakhe isixhumanisi sengoma. Amaphethelo amabili esicathulo sethrekhi anezimbobo, axhunywe ngesondo elisebenzayo, futhi kukhona amazinyo ahlabayo phakathi, asetshenziselwa ukuqondisa ithrekhi futhi avimbele ithrekhi ukuthi ingawi lapho ithangi liphendulwa noma ligoqwa, futhi kukhona ubambo oluqinile oluphikisana nokushelela (okubizwa ngokuthi iphethini) ohlangothini lokuthintana komhlabathi ukuthuthukisa ukuqina nokuqina kwethrekhi yesicathulo.
