Crane ndi chimodzi mwa zida zodziwika bwino komanso zofunika kwambiri pantchito yomanga.Chiyambi chake chimachokera ku zitukuko zakale monga Agiriki ndi Aroma, omwe ankagwiritsa ntchito makina osavuta monga ma pulleys ndi levers kunyamula zinthu zolemera.Komabe, sizinali mpaka nthawi ya Industrial Revolution pomwe crane yamakono monga tikudziwira lero idayamba kupangidwa.
Kusintha kwa crane kwakhala umboni wa luso la anthu komanso luso la uinjiniya.Kuchokera ku makina osavuta ogwiritsidwa ntchito ndi manja akale kupita ku zinyumba zazikulu, zazitali zomwe zimayang'anira mizinda yamakono, crane yafika patali.Masiku ano, ma cranes ndi ofunika kwambiri pomanga, komwe amagwiritsidwa ntchito kunyamula ndi kusuntha zinthu zolemera monga matabwa achitsulo, konkire, ndi makina.
Pali mitundu yosiyanasiyana ya cranes, iliyonse yopangidwira ntchito zapadera komanso momwe amagwirira ntchito.Mtundu wodziwika kwambiri ndi nsanja ya nsanja, yomwe nthawi zambiri imawonedwa pama projekiti apamwamba kwambiri.Ma cranes amatha kufika pamtunda waukulu komanso amatha kukweza matani angapo.Mtundu wina wotchuka ndi crane yam'manja, yomwe imayikidwa pagalimoto ndipo imatha kutengedwa kupita kumalo osiyanasiyana ogwira ntchito.Mitundu ina ndi monga crane yam'mwamba, crane rough terrain, ndi telescopic crane.
Kupita patsogolo kwaumisiri wa crane kwapangitsanso kuti pakhale makina apakompyuta omwe amathandiza oyendetsa galimotoyo kuwongolera ndi kuyendetsa makinawo molondola.Machitidwewa amagwiritsa ntchito masensa ndi makamera kuti apereke ndemanga zenizeni zenizeni, kuonetsetsa chitetezo cha onse ogwira ntchito ndi omwe amagwira ntchito pansi.Kuphatikiza apo, ma cranes amakono ali ndi zinthu monga zotsutsana ndi kugundana ndi zida zowunikira katundu, zomwe zimakulitsa luso lawo komanso chitetezo.
Komabe, kugwiritsa ntchito ma cranes kumabwera ndi zovuta zake komanso zovuta zake.Ngozi zokhala ndi ma cranes zitha kukhala ndi zotsatira zoyipa, chifukwa chake ndikofunikira kutsatira malamulo okhwima otetezedwa.Maphunziro oyenerera ndi chiphaso cha oyendetsa crane ndizofunikiranso kuti awonetsetse kuti ali ndi luso komanso chidziwitso chogwiritsa ntchito zidazo mosamala.
M'zaka zaposachedwa, ntchito yomanga yawona kuchuluka kwa ma cranes pomwe ntchito zakumizinda ndi zomangamanga zikukulirakulira.Izi zapangitsa kuti zida za crane zikhale zogwira mtima komanso zokhazikika.Mwachitsanzo, makampani ena apanga makina opangira magetsi omwe amatulutsa mpweya wochepa komanso phokoso, zomwe zimawapangitsa kukhala osakonda chilengedwe.
Pamene tikuyang'ana zam'tsogolo, mosakayika crane idzapitiriza kugwira ntchito yofunika kwambiri pakupanga mawonekedwe a mizinda ndi matauni athu.Ndi kupita patsogolo kwaukadaulo komanso kugogomezera kwambiri chitetezo ndi kukhazikika, crane ikhalabe mwala wapangodya wamakampani omanga kwazaka zikubwerazi.Kukhoza kwake kunyamula, kusuntha, ndi kunyamula katundu wolemera kudzapitiriza kukhala wofunika kwambiri pa chitukuko cha malo athu omangidwa.Kuyambira kale mpaka lero, crane yatsimikizira kukhala chizindikiro cha nzeru zaumunthu ndi kupita patsogolo.
