Chifukwa chakuti gulu lolimbana ndi vuto lomwe lili m'bokosi lolimbana ndi vuto la crane limagwira ntchito nthawi zambiri, kutentha kwakukulu kumapangidwa, zomwe zimapangitsa kuti gulu lolimbana ndi vuto likhale lotentha kwambiri. M'malo otentha kwambiri, resistor yokha komanso malo olumikizirana ndi resistor amatha kuwonongeka.
Nthawi yomweyo, kusintha kwa ma contactor osiyanasiyana a AC kumawonjezekamakina opukutira mlathoimakhala yokwera kwambiri panthawi yogwira ntchito. Zolumikizira zake zimawonongeka mosavuta komanso zimakalamba nthawi zambiri zikasinthana, zomwe zimapangitsa kuti zolumikizira zina zikhale ndi kukana kowonjezereka kwa kukhudzana kapena kutayika kwa gawo, zomwe zimapangitsa kuti kukana kwa injini kusakhale kolinganizika. Izi zitha kubweretsa kuwonongeka kwa injini ndi kulephera pamene crane yadzaza kwambiri kapena ikugwira ntchito kwa nthawi yayitali.
Kaya ndi kusalingana kwa kukana kwa injini kapena kusalingana kwa ma voltage atatu, injiniyo imapanga mawu osazolowereka ndi zochitika zina zosazolowereka, kaya zazitali kapena zazifupi, zamphamvu kapena zofooka. Ngati injini yoyendetsa ipanga kukwera kwa kutentha kwakukulu pakapita nthawi yochepa, injiniyo idzagwedezeka kwambiri, ndipo crane ikhoza kukumana ndi vuto "lopanda mphamvu". Ma brake pads a injiniyo adzagundana, ndikupanga mawu okangana othamanga kwambiri komanso osakhazikika, ndipo pakapita nthawi, kuwonongeka kwa injini kungachitike. Pakadali pano, makinawo ayenera kuyimitsidwa nthawi yomweyo kuti akonzedwe ndikuyang'aniridwa nthawi yake.
Kuti mupewe ngozi zotere, ogwira ntchito yokonza nthawi zonse ayenera kukonzedwa kuti ayang'ane ndikusamalira bokosi lolimbana ndi magetsi ndi bokosi lowongolera. Limbikitsani kuwunika kwa zinthu zosatetezeka mu dongosolo la chingwe cholumikizira magetsi, ndikukonza mwachangu kapena kusintha nthawi zonse chosonkhanitsa chamagetsi. Nthawi zonse kapena pafupipafupi onani momwe njanji yotsogolera waya wotsetsereka ndi foloko imakhalira, sinthani cholumikizira choyandama kuti payipi ikule ndikuchepa momasuka. Kuphatikiza apo, ndikofunikira kuyang'ana nthawi zonse mabolts omangira ndi mawaya a zida zamagetsi, ndikuyika ma spring pads kapena ma anti vibration rabara pads. Konzani bwino dera lamagetsi la crane panthawi yoyika, ndikupewa kulumikiza zida zina zamagetsi zamagetsi pamabwalo odzipereka.
