Abahlinzeki bemishini yempendulo yamandla bakukhumbuza ukuthi ama-cranes ayimishini emikhulu enamahora amaningi okusebenza aqhubekayo kanye nomfutho ophakeme wokusebenza, okuholela ekusetshenzisweni okukhulu kukagesi. Ngokukhula kwenkinga enkulu yokuphela kwamandla kagesi, ukongiwa kukagesi sekuyindaba ebaluleke kakhulu, futhi indlela yokunciphisa ukusetshenziswa kwamandla kagesi sekuyinkinga enkulu embonini.
Ukunciphisa isisindo se-crane, ukwakheka kwensimbi kubala iningi lesisindo, futhi ukwamukela izindlela zesitayela saseYurophu kunganciphisa kakhulu isisindo nevolumu yesakhiwo sensimbi.
Ukwenza ngcono isimo sesigubhu, isigubhu esinobubanzi obukhulu singasetshenziswa ukwandisa umthamo wezintambo futhi sinciphise ubukhulu nesisindo setroli ephakamisayo.
Ukusebenzisa izinto ezintsha, njengokusebenzisa inayiloni enamandla amakhulu esikhundleni sensimbi ecijile noma insimbi, akukwazi nje ukwelula isikhathi sokuphila kodwa futhi kunciphise nomsindo.
Qinisa ukugcinwa kwansuku zonke kwama-cranes futhi ungakubukeli phansi. Ukunakekelwa kwansuku zonke kungasiza kakhulu ekunciphiseni ukulimala kwesakhiwo futhi konge amandla kuma-cranes.
Kwenziwe ngcono uhlelo lokulawula, nesistimu yokulawula isivinini ithathelwa indawo yisistimu yokulawula isivinini esishintshashintshayo. Ukonga amandla kungafezwa futhi ngokufaka umshini wokuphendula osebenza kahle kakhulu oklanyelwe ngokukhethekile okokusebenza kokugcwala kwamandla, esebenzisa "i-voltage egcwele yokulandela ngomkhondo ngokuzenzakalelayo" kanye nobuchwepheshe bokucubungula "iphoyinti elinguziro lamanje" ukuze kuthuthukiswe ikhwalithi yempendulo yamanje egeleza ephuzwini elinguziro, kuthuthukise ukuzinza kwempendulo egcwele ngokweqile kanye nesici samandla, kanjalo nokubuyisela amandla kagesi avuselelwe akhiqizwa ngesikhathi senqubo yokulawula isivinini semoto kugridi, ukuzuza imiphumela ebalulekile.
Imiphumela eyinhloko ibonakala ku:
(1) Ukuma okunembile nokusebenza kahle okuphezulu
Ngeke kube khona okwenzekayo lapho ijubane lemoto lishintsha nomthwalo wama-cranes wendabuko, okungathuthukisa ukukhiqizwa kokulayisha nokukhipha imisebenzi.
(2) Ukusebenza okushelelayo nokuphepha okuphezulu
Ngesikhathi sokusebenza, ukudlidliza kanye nomthelela wawo wonke umshini kuncishiswa kakhulu ngesikhathi sokusheshisa nokwehla, okwandisa impilo yesevisi yesakhiwo sensimbi ye-crane kanye nezingxenye zemishini futhi kuthuthukisa ukuphepha kwemishini.
(3) Yehlisa isondlo kanye nezindleko eziphansi
Impilo yesevisi yama-brake pads iyanwetshwa, futhi izindleko zokunakekela zincishiswa kakhulu.
(4) Izinga lokuhluleka eliphansi
Ukusetshenziswa kwama-squirrel cage ama-asynchronous motors esikhundleni se-rotor yesilonda ama-asynchronous motors agwema ukulimala kwemoto noma ukwehluleka ukuqala ngenxa yokuxhumana okungalungile.
(5) Ukungcola okuphansi kwe-harmonic
Ukungcoliswa kwe-harmonic kokunikezwa kwamandla kungaphansi kuka-2%, futhi isici samandla esigcwele sisondele ku-"1"
(6) Yenza kube lula ukujikeleza
Isekethe eyinhloko yemoto kagesi ifinyelele ukulawulwa kokungathintwa, ukugwema ukulimala kukagesi okubangelwa ukunyakaza okuvamile kothintana naye kanye nokulimala kukagesi okubangelwa ukutubeka kokuxhumana.
