Umhlaba wamakheshi uhlala ushintsha ukuze kuqinisekiswe ukuphepha, ukwethembeka, nokusebenza kahle kwamandla. Izinqamuleli zamabhuleki zidlala indima ebalulekile ekulolongeni lolu shintsho, zinikeza izixazululo ezintsha embonini yezikheshi. Njengoba amakheshi enza imijikelezo yokusheshisa nokuhlehlisa, isidingo samasistimu okubhuleka anokwethenjelwa siba phambili. Izinqamuleli zamabhuleki zihamba phambili ekubhekaneni nale nselele, zihlinzeka ngemisebenzi ebalulekile ekulawuleni isivinini, ukuqinisekisa ukuma okushelelayo, nokuvimbela ukuguga nokudabuka ngokweqile ezingxenyeni zekheshi.
Esinye sezicelo ezibalulekile zama-braking resistors kumakheshi ukubhuleka kabusha. Lapho ikheshi lehla noma lehlisa ijubane, likhiqiza amandla e-kinetic engeziwe. Esikhundleni sokuchitha la mandla njengokushisa, ama-braking systems avuselelayo ayawabophela futhi awaguqule abe amandla kagesi. Izinqamuleli zamabhuleki zidlala indima ebalulekile ekumunceni nasekuchitheni la mandla ayinsalela, okunomthelela ekongeni amandla nasekusimameni kwemvelo. Ngaphezu kwalokho, izinto ezivimbela amabhuleki zithuthukisa ukuphepha ngokwenza kube lula ukulawula ukunyakaza kwekheshi. Ezimeni zezimo eziphuthumayo, zisiza ukumisa ikheshi ngokushesha nangokuphephile, kuncishiswe izingozi ezingaba khona kanye nokuqinisekisa ukuphepha kwabagibeli.
Ngaphezu kokuphepha nokusebenza kahle kwamandla, izinsimbi zokubopha amabhuleki nazo zifaka isandla ekwandiseni isikhathi sokuphila sezingxenye zamakheshi. Ngokunciphisa ubunzima bemishini kanye nezinhlelo zikagesi ngesikhathi sokubhuleka, zisiza ukunciphisa izidingo zokunakekelwa nokuthuthukisa ukuthembeka kukonke kwamakheshi. Ukuze kuhlangatshezwane nezidingo eziguqukayo zemboni yezikheshi, abakhiqizi baqhubeka bethuthukisa ubuchwepheshe be-braking resistor. Ukuthuthukiswa kwezinto eziphikisayo ezihlangene, ezisebenza kahle kakhulu kuvumela ukuhlanganiswa okungenamthungo ezinhlelweni zamakheshi esimanje, kuthuthukisa ukusetshenziswa kwesikhala ngenkathi iletha ukusebenza okuthuthukisiwe.
