I-crane yeloli yaseChina yazalwa ngawo-1970.Ngemva kweminyaka ecishe ibe ngu-30 yentuthuko, kube nentuthuko enkulu yobuchwepheshe emithathu phakathi naleso sikhathi, okuwukuthi ukwethulwa kobuchwepheshe baseSoviet ngeminyaka yawo-1970, ukwethulwa kobuchwepheshe baseJapane ngawo-1980, kanye nokwethulwa kobuchwepheshe ngawo-1990.Ubuchwepheshe baseJalimane.Kodwa ngokuvamile, imboni ye-crane yamaloli yaseChina ibilokhu isendleleni yokusungula izinto ezizimele futhi inomongo wayo wentuthuko ocacile.Ikakhulukazi eminyakeni yamuva, imboni ye-crane yeloli yaseChina yenza intuthuko enkulu, nakuba iqhathaniswa namazwe angaphandle Kukhona igebe elithile, kodwa leli gebe liyancipha kancane kancane.Ngaphezu kwalokho, ukusebenza kwama-cranes amaloli amancane naphakathi aseShayina sekuvele kuqinile, okungahlangabezana nezidingo zokukhiqiza kwangempela.
imboni yezwe lakithi ye-crane crane idlule ohlelweni lokuthuthukiswa kusukela ekulingiseni kuya ocwaningweni oluzimele nokuthuthukiswa, kusukela kumthamo omncane wokulayisha kuya emandleni amakhulu.Ekuqaleni kwentuthuko, okwakugxilwe kakhulu ekwethulweni kobuchwepheshe obuphambili bangaphandle, futhi kwaba nezingeniso ezintathu ezibalulekile zobuchwepheshe: ubuchwepheshe baseSoviet ngeminyaka yawo-1970, ubuchwepheshe baseJapane ekuqaleni kwawo-1980, kanye nobuchwepheshe baseJalimane ekuqaleni kwawo-1990.Ngokuvinjelwa izinga lesayensi nobuchwepheshe ngaleso sikhathi, amandla okuphakamisa ama-cranes ngaphambi kweminyaka yawo-1990 ayemancane uma kuqhathaniswa, phakathi kwamathani angu-8 namathani angama-25, futhi ubuchwepheshe babungakavuthwa.Ngokuya ngamamodeli womkhiqizo, okhreyini bamaloli bokuqala be-Taian QY bamukelwa kahle ngabasebenzisi.
Ngemva kokungena kweShayina ku-WTO ngo-2001, isidingo sasekhaya sama-cranes amaloli sikhulile, futhi imakethe iphinde yagqugquzela abakhiqizi ukuthi bakhiqize imikhiqizo enekhwalithi ephezulu, ukusebenza okuqinile, ukuphepha okungcono, futhi ukuhlangabezana kangcono nezidingo zomsebenzi.Ngemva kokungena ekhulwini lama-21, abakhiqizi abaningi be-crane bamaloli basekhaya baye benza ukuhlanganisa nokuthengwa, kanye nemboni yasekhaya ye-crane yamaloli ne-Zoomlion, i-Sany Heavy Industry, i-Xugong kanye ne-Liugong njengamandla amasha amakhulu angena esigabeni sokucwaninga nokuthuthukiswa okuzimele.Ngokuhlanganyela phakathi kwe-Tai'an Dongyue ne-Manitowoc yase-United States, kanye nebhizinisi elihlanganyelwe phakathi kwe-Changjiang Qigong kanye ne-Terex yase-United States, abakhiqizi bangaphandle nabo bajoyine umncintiswano wama-cranes amaloli asekhaya.
Ngokuthuthuka kwemboni ye-crane, ukuthuthukiswa kwezinga lobuchwepheshe kwenze kwaba nokwenzeka ukuthuthukisa amandla okuphakamisa u-crane, futhi amandla e-crane yeloli mayelana nokuguquguquka, amandla okuphakamisa kanye nendawo yokusebenza ephumelelayo iye yathinta kancane kancane ukuze ukuhlangabezana nezidingo zemisebenzi eyahlukene.Ngemva kokungena ekhulwini lama-21, amandla okuphakamisa isizukulwane esisha sama-cranes wamaloli aya ngokuya ekhuphuka, futhi ubuchwepheshe buya ngokuya buvuthwa.
Kusukela ngo-2005 kuya ku-2010, kwaba nokuthuthuka okujwayelekile embonini yemishini yokwakha, futhi ukuthengiswa kwama-cranes wamaloli nakho kwafinyelela phezulu.Ngemva kweminyaka yokuthuthuka ngokushesha, ama-cranes amaloli asefinyelele ezingeni elihamba phambili emhlabeni.NgoNovemba 2010, i-crane yeloli elikhulu lamathani angu-XCMG i-QY160K yenza ukubukeka okuhle kakhulu e-Shanghai Bauma Exhibition.I-QY160K njengamanje ingu-crane wamaloli omkhulu kunawo wonke emhlabeni.
Kusukela ngo-2011, imboni ye-crane yamaloli kanye nayo yonke imboni yemishini yokwakha ibe sengozini.Kodwa-ke, ukwakhiwa kwengqalasizinda akukavimbeki, isidingo sama-cranes amaloli sisaqinile esikhathini esizayo, futhi abakhiqizi nabasebenzisi babheke ngabomvu ukubuya kwenkathi ephezulu.Imakethe ye-crane yeloli elungisiwe izolingana futhi ihleleke, futhi sibheke ngabomvu ukuvela kwemikhiqizo eminingi futhi engcono kakhulu ye-crane yamaloli.
