Chifukwa chakuti gulu lotsutsa mu bokosi lotsutsa la crane limagwira ntchito nthawi zambiri, kutentha kwakukulu kumapangidwa, zomwe zimapangitsa kutentha kwakukulu kwa gulu lotsutsa. M'malo otentha kwambiri, zopinga zokha komanso zolumikizira zolumikizira zimatha kuwonongeka.
Pa nthawi yomweyo, kusintha pafupipafupi zosiyanasiyana AC contactors mumilatho cranesimakhala yokwera kwambiri panthawi yogwira ntchito. Zolumikizira zake zimawonongeka mosavuta komanso kukalamba nthawi zambiri zimasintha, zomwe zimapangitsa kuti ena azilumikizana ndi kukana kapena kutayika kwa gawo, zomwe zimapangitsa kukana kosagwirizana kwa mafunde agalimoto. Izi zingayambitse kuwonongeka kwa galimoto ndi kulephera pamene crane yadzaza kapena kugwira ntchito kwa nthawi yaitali.
Kaya ndi kusalinganika kwa kukana kwa mota kapena kusalinganiza kwa ma voltages atatu, mota imatulutsa mawu osadziwika bwino ndi zochitika zina zachilendo, kaya zazitali kapena zazifupi, zamphamvu kapena zofooka. Ngati galimoto yoyendetsa galimoto imapanga kutentha kwakukulu pakanthawi kochepa, galimotoyo imagwedezeka kwambiri, ndipo crane ikhoza kukumana ndi "zopanda mphamvu". Ma brake pads a mota amawombana wina ndi mnzake, kutulutsa mawu othamanga kwambiri komanso osakhazikika, ndipo pakapita nthawi, kuwonongeka kwa mota kumatha kuchitika. Panthawiyi, makinawo ayenera kuyimitsidwa nthawi yomweyo kuti akonze ndi kuyang'anitsitsa panthawi yake.
Pofuna kupewa ngozi zoterezi, ogwira ntchito yokonza nthawi zonse ayenera kukonzedwa kuti ayang'ane ndi kusunga bokosi loletsa ndi bokosi lowongolera. Limbikitsani kuwunika kwa zigawo zomwe zili pachiwopsezo mu dongosolo lamagetsi otsetsereka otsetsereka, ndikukonza mwachangu kapena nthawi zonse m'malo mwa wokhometsa. Yang'anani pafupipafupi kapena pafupipafupi momwe njanji yotsetsereka imayendera ndi foloko, sinthani chingwe choyimitsira choyandama kuti ngalandeyo ikule ndikulumikizana momasuka. Kuphatikiza apo, ndikofunikira kuyang'ana pafupipafupi ma bolts ndi ma wiring terminals azinthu zamagetsi, ndikuyika mapepala a kasupe kapena ma anti vibration rabara. Konzani moyenerera dera loperekera magetsi la crane panthawi yoyika, ndipo pewani kulumikiza zida zina zamagetsi apamwamba pamagawo odzipereka.
