Ukusetshenziswa kweibhulekieresistorskumishini ye-crane ibalulekile ekusebenzeni okuphephile nokusebenza kahle kwemishini.Indlela yokusebenza yemishini yokuphakamisa ku-crane iwukuthi: injini isebenza esimweni sokukhiqiza amandla lapho ihamba phansi, futhi injini isebenza lapho ihambela phezulu.Uma kungekho ukumelana ne-braking engeziwe, ugesi owenziwe yi-motor uzosebenza ngokuqondile ku-module ye-inverter, okubangela ukulimala okuvamile kumojula.
Ngesikhathi senqubo yokuncishiswa kwezimoto, inertia yemishini eningi izokwenzaphendukainjini ibe yijeneretha, okubangela ukuthi injini inikeze amandla ku-inverter ngakolunye uhlangothi.Lokhu kungase kubangele i-alamu ye-over-voltage ku-inverter.Ukuze uxazulule le nkinga, indlela yokwandisa amandla okuphikisa (ukunciphisa ngokufanelekile inani lokumelana) ingasetshenziswa ukukhulula amandla amaningi.Ukwengeza, ezinye izinqamuleli zamabhuleki zinganikeza amandla abuyele emuva ku-loop yamandla, ewusizo ikakhulukazi kumasistimu amafrikhwensi ahlukahlukene anebhasi elivamile le-DC futhi kusiza ukonga amandla.
Iibhulekieisiphikisaidlala indima ebalulekile ekuvimbeleni ukugcwala kwe-voltage ngokweqile kwesiguquli sefrikhwensi ngesikhathi sokwehla, sifinyeze ibanga lokusheshisa, futhi sithuthukise ukusebenza okuguquguqukayo kukonke kwemishini yokuphakamisa.Nakuba ibhuleki elakhelwe ngaphakathi lemoto lisetshenziswa kakhulu ekubhulekeni kokugcina kokupaka, alisebenzi ekubhulekini kwe-deceleration.Kulapho-ke i-resist braking iqala khona ukusebenza njengoba ithinta kuphela injini ngesikhathi ihlehla futhi ayinamthelela uma injini isimisiwe.Ukugcina injini imile ngaphansi komthwalo ongase ube khona, kufanele kusetshenziswe ibhuleki.
Ngokuphathelene nohlobo lwama-resistors amabhuleki asetshenziswa emishinini yokuphakamisa, izinto eziphikisa amakesi e-aluminium nama-ripple resistors ngokuvamile asetshenziselwa ukuqalisa umthwalo.Lawa ma resistor amabhuleki nawo angabekwa phezu kwesinye, kodwa kubhekwe ukuphepha kanye nokufakwa ngendlela efanele.Uma inani lezinto eziphikisayo lidlula u-4, kufanele zibekwe ohlakeni lwensimbi olukhethekile kuyilapho kugcinwa ibanga elingu-80mm phakathi kwamasethi amabili aseduze aphikisanayo.Ukwengeza, isivikelo sokushisa singafakwa phakathi nendawo ukuze kuvikeleke okwengeziwe.Kuyadingeka ukuqinisekisa ukuthi izikulufi zisekelwe ngokuqinile ukuze kuvinjelwe izingozi noma ukushaqeka kukagesi kubasebenzi ngesikhathi sokufakwa.
Kafushane, ukusetshenziswa kwe ama-brake resistors kumishini ye-crane kubalulekile ukuphatha ukukhishwa kwamandla ngesikhathi sokuncipha, ukuvimbela ukulimala kusiguquli semvamisa, kanye nokwenza ngcono ukusebenza nokuphepha kukonke.Ukufakwa kahle nokuqonda umsebenzi we-braking resistor kubalulekile ekusebenzeni kahle kwemishini ye-crane.
