Umphakeli wedivayisi yempendulo yamandla ekheshi ukukhumbuza ukuthi ukusebenza kwekheshi kuwukunyakaza okubuyela emuva kwemoto kanye nedivayisi ye-counterweight, futhi i-counterweight ngokuvamile inzima kunemoto. Ikheshi lishayelwa phezulu naphansi ngomshini wokudonsa, futhi umthwalo oshayelwa umshini wokudonsa wakhiwe imoto yabagibeli kanye ne-counterweight balance block. Kuphela uma umthamo womthwalo wemoto ucishe ube ngu-50% (njenge-lifti yomgibeli enethani elingu-1 elinabagibeli abangaba ngu-7), imoto kanye ne-counterweight balance block kuzolingana. Uma kungenjalo, kuzoba nomehluko wekhwalithi phakathi kwemoto ne-counterweight.
Inqubo yokusebenza kwekheshi inqubo yokuguqula amandla kagesi abe amandla emishini. Lapho ikheshi ligcwele kakhulu futhi liya phezulu noma lilayishwa kancane futhi liya phansi, amandla adinga ukuhlinzekwa ku-elevator ukuze kwandiswe amandla anamandla okusebenza. Ikheshi liguqula amandla kagesi abe amandla anamandla kagesi ngomshini wokudonsa, osesimweni sokudla amandla; Uma ilifti ilayishwe phezulu kancane noma ilayishwe kakhulu, inqubo yokusebenza idinga ukunciphisa amandla anamandla emishini. Amandla anamandla emishini ekheshi aguqulwa abe amandla kagesi umshini wokudonsa, osesimweni sokukhiqiza.
Ngaphezu kwalokho, inqubo yamakheshi ukusuka ekusebenzeni ngesivinini esikhulu ukuya ekumisweni kwamabhuleki kuyinqubo yokusebenzisa amandla e-kinetic ngomshini, futhi ingxenye yamandla e-kinetic iguqulwa ibe amandla kagesi ngomshini wokudonsa, osenqubo yokukhiqiza ugesi. Amandla kagesi akhiqizwa ngesikhathi senqubo yokuphehla amandla omshini wokudonsa kudingeka kubhekwane nawo ngesikhathi, ngaphandle kwalokho kuzodala umonakalo omkhulu emshinini wokudonsa. Kuma-lifti amafrikhwensi aguquguqukayo, amandla kagesi akhiqizwe umshini wokudonsa ngesikhathi senqubo yokuphehla amandla abuyiselwa emuva ekupheleni kwe-DC yesiguquli sefrikhwensi ngebhuloho le-inverter lezigaba ezintathu lesiguquli sefrikhwensi futhi agcinwe ku-DC capacitor. Nokho, amandla e-DC capacitor anomkhawulo. Lapho amandla kagesi akhiqizwa umshini wokudonsa edlula umthamo we-DC capacitor, azodala umonakalo ku-DC capacitor, ngakho-ke amandla kagesi angaphezu kwamandla kufanele adliwe.
Indlela evamile yokuphatha le ngxenye yamandla kagesi kusikheshi sefrikhwensi eguquguqukayo ukufaka iyunithi yokubhuleka kanye ne-resistor yokubhuleka ekugcineni kwe-DC capacitor. Lapho i-voltage kuyo yonke i-capacitor ifinyelela inani elithile, iyunithi yokubhuleka izosebenza, futhi amandla kagesi engeziwe azoguqulwa abe amandla ashisayo ngesixhasi sokubhuleka futhi ahlakazeke emoyeni. Idivayisi yempendulo yamandla kagesi ingena esikhundleni seyunithi yokubhuleka kanye ne-resistor yokubhuleka. Ngokuthola ngokuzenzakalelayo i-voltage yebhasi ye-DC yesiguquli sefrikhwensi, i-voltage ye-DC yesixhumanisi se-DC yesiguquli sefrikhwensi ihlehliswa ibe i-AC enefrikhwensi kanye nesigaba njenge-voltage yegridi. Ngemva kwezixhumanisi eziningi zokuhlunga umsindo, ixhunywa kugridi yamandla we-AC ukuze kuzuzwe izinjongo eziluhlaza, ezinobungani nemvelo, nezokonga amandla.
Idivayisi yempendulo yamandla ekheshi iyidivayisi eguqula amandla kagesi akhiqizwe umshini wokudonsa wekheshi ngaphansi komthwalo ongalinganisiwe ibe amandla ekhwalithi ephezulu e-AC wefrikhwensi efanayo nesigaba njengegridi yamandla, futhi iwabuyisela kugridi yamandla wendawo ngokuguquguquka. Izosetshenziswa kumabhodi omama wekheshi, izibani ze-elevator shaft, izibani zemoto, amafeni ezimoto, nezindawo eziseduze ezinemithwalo (noma amanye amakheshi ahambisanayo nemishini ehambisanayo).
