Ngenxa yokuthi iqembu lokumelana ebhokisini lokumelana le-crane lisebenza kakhulu ngesikhathi sokusebenza okuvamile, kukhiqizwa ukushisa okukhulu, okuholela ekushiseni okuphezulu kweqembu lokumelana. Ezindaweni zokushisa okuphezulu, kokubili i-resistor uqobo kanye nama-terminals okuxhuma i-resistor avame ukuwohloka.
Ngesikhathi esifanayo, imvamisa yokushintsha kwama-contactor ahlukahlukene e-AC kuamakhreni ebhulohoiphakeme kakhulu ngesikhathi sokusebenza. Oxhumana nabo bayo bayalimala kalula futhi baguge ngesikhathi sokushintsha njalo, okubangela ukuthi abanye oxhumana nabo babe nokumelana okukhulu kokuxhumana noma ukulahleka kwesigaba, okuholela ekumelaneni okungalingani kochungechunge lokugoba kwenjini. Lokhu kungaholela ekulimaleni kwenjini kanye nokwehluleka kwayo uma i-crane igcwele ngokweqile noma isebenza isikhathi eside.
Kungakhathaliseki ukuthi ukungalingani kokumelana ochungechungeni kwemoto noma ukungalingani kwama-voltage amathathu, imoto izokhiqiza imisindo engavamile kanye nezinye izinto ezingavamile, kungaba zinde noma zimfushane, zinamandla noma zibuthakathaka. Uma imoto eshayelayo ikhiqiza ukwenyuka kwezinga lokushisa eliphezulu esikhathini esifushane, imoto izozamazama kakhulu, futhi i-crane ingase ibhekane nesenzakalo "esingenamandla". Ama-brake pad emoto azoshayisana, akhiqize imisindo yokungqubuzana evame kakhulu futhi engazinzile, futhi ngokuhamba kwesikhathi, umonakalo wemoto ungase uvele. Kuleli qophelo, umshini kufanele umiswe ngokushesha ukuze kulungiswe futhi kuhlolwe ngesikhathi esifanele.
Ukuze kuvinjelwe izingozi ezinjalo, izisebenzi zokulungisa ezivamile kufanele zihlelwe ukuhlola nokugcina ibhokisi lokumelana nebhokisi lokulawula. Qinisa ukuhlolwa kwezingxenye ezisengozini ohlelweni lokuxhumana olushelelayo lokunikezwa kwamandla kagesi, futhi ulungise ngokushesha noma ushintshe njalo i-current collector. Hlola njalo noma kaningi isimo sesitimela sokuqondisa ucingo olushelelayo kanye nefoloko, lungisa i-floating suspension clamp ukuze uvumele i-conduit ukuthi ikhule futhi inciphe ngokukhululeka. Ngaphezu kwalokho, kuyadingeka ukuhlola njalo amabhawodi okulungisa kanye nama-wiring terminals ezingxenye zikagesi, bese ufaka ama-spring pads noma ama-anti vibration rubber pads. Hlela kahle i-power supply circuit ye-crane ngesikhathi sokufakwa, futhi ugweme ukuxhuma eminye imishini yokunikezwa kwamandla aphezulu kuma-circuits anikezelwe.
