Uma inani lemisebenzi yokumaka lingelikhulu, njengokudweba kabusha izingxenye ezithile zomugqa omdala, ungasebenzisa ukusunduza ngesandla okuvamile noma umshini womaka obanjwa ngesandla oncibilika oshisayo.Ngoba iumshini omncane wokumaka oshisayoincane ngosayizi, iyaguquguquka ekwakhiweni futhi ilungele ezokuthutha, ithimba lokwakha lingaphuthuma ngokushesha esigabeni sokwakha ukuze liqedele ukwakha nalo.Ithimba lokwakha elinolwazi liyazi ukuthi izinga lokumaka lihlobene eduze nezici eziningi, njengokuthi: imvelo yomgwaqo, ikhwalithi yokumaka upende, ikhwalithi yomgwaqo, umswakama womoya kanye nezinga lokushisa ngesikhathi sokwakhiwa, njll. Umshini wokumaka, nakuba esinye sezici ezibalulekile ezithinta ikhwalithi yokumaka, akuyona into enqumayo.

Izinga lomshini wokumaka linquma ukusebenza kahle kokwakhiwa kokumaka.Umsebenzi omkhulu womshini wokumaka ukuvumela abasebenzisi ukuthi bonge kakhulu isikhathi nezindleko zabasebenzi.Umshini wokumaka ogibelayo ungakha isilinganiso samakhilomitha ayi-10 ngehora, kanti umshini wokumaka ngesandla ungasebenza amahora angu-8 ngosuku ukwakha amakhilomitha angu-5-6.Thatha i-expressway engamakhilomitha angu-100 njengesibonelo.Sebenzisa aumshini wokumaka wokugibelaukuchitha usuku nesikhathi esengeziwe esincane ukuze uqedele umsebenzi.Yiqiniso, lesi yisimo esihle.Ukwakhiwa kwangempela kungase kuthathe isikhathi esengeziwe, ngakho-ke masikwelule isikhathi eside futhi sibale njengezinsuku ezi-3.;Futhi umshini wokumaka ophushwe ngesandla wendabuko ufuna ukuqeda iphrojekthi yokumaka engamakhilomitha ayi-100 phakathi nezinsuku ezi-3, noma ngabe imishini yokumaka eyi-5 ephushwa ngesandla isetshenziswa ndawonye ukuze kusebenze isikhathi esengeziwe, kungenzeka bangakwazi ukuyiqeda.Ngaphezu kwalokho, uma lina ngesikhathi sokwakhiwa komshini wokumaka, inqobo nje uma imvula ingayeki, isikhathi sokwakha sizonwetshwa ngokungapheli.Ikakhulukazi ngenkathi yemvula eningizimu, izimo ezinjalo zivame kakhulu.Umshini wokumaka wokugibela ungabamba isimo sezulu esihle esingandile kule sizini futhi uqedele ukwakhiwa ngesikhathi esifushane.Uma nje ukwakhiwa kokumaka kuqediwe lapho umgwaqo womile, imvula enkulu kamuva izoba nomthelela omncane kwikhwalithi yokumaka.

Njengoba izindleko zomsebenzi wasekhaya ziba phezulu kakhulu, izinzuzo zomshini wokumaka wokugibela zizoba sobala kakhulu.Ukuyisebenzisela ukumaka nsuku zonke kulingana nokuzisindisa izisebenzi ezi-5-6 nsuku zonke izinsuku ezi-3.Ngaphezu komshini kalayini, kunomshini wokumaka umugqa osebenza kahle kakhulu, okuyimoto yokumaka umugqa.Ububi bomshini wokumaka wokugibela ukuthi imishini inkulu futhi ayilula kakhulu ukuthutha.Uma ithimba lezokwakha lithola ibhizinisi lokwakha lokumaka lesifundazwe, kuba nzima kakhulu ukudonsa umshini wokumaka wokugibela.Ngakho-ke, ukuze unqobe lesi siphetho, kwazalwa imoto entsha sha enkulu yokumaka imishini yokumaka.
