Amakhreni angaphezuluziyizingxenye ezibalulekile zemishini esetshenziswa ezindaweni ezahlukahlukene zezimboni. Yi-crane esebenza kumzila ophakeme noma ohlelweni lwemigwaqo ukuze ihambise izinto kanye nemithwalo ngokuvundlile nangokuqondile ngaphakathi kwesikhungo. Lawa ma-crane avame ukusetshenziswa ekukhiqizeni, ekwakheni, nakwezinye izindawo zezimboni ukuze kube lula ukuphakamisa nokuthutha izinto ezisindayo.
Amakhreni ebhulohozenzelwe ukuphatha izinto ezahlukahlukene, kusukela ezintweni zokusetshenziswa enqubweni yokukhiqiza kuya emikhiqizweni eseqediwe elungele ukuthunyelwa. Zifakwe i-hoist, okuyiyona ingxenye yokuphakamisa ye-crane futhi zingalungiswa ngamakhono ahlukene okuphakamisa ukuze kuhlangatshezwane nezidingo ezithile zohlelo lokusebenza. Ngaphezu kwalokho, lawa ma-crane angasetshenziswa ngesandla ngesilawuli sokumiswa esinentambo noma isilawuli kude esingenantambo ukuze kuthuthukiswe ukusebenza kahle nokuphepha.
Amakhreni aphezulu ezimbonizidlala indima ebalulekile ekwenzeni lula izinqubo zokuphatha izinto, zandise umkhiqizo futhi zithuthukise ukuphepha emsebenzini. Ngokuhambisa imithwalo esindayo kahle, zisiza ekunciphiseni umsebenzi wezandla kanye nengozi yezingozi ezihlobene nokuphakamisa nokuthutha izinto. Ngaphezu kwalokho, ama-crane angaphezulu asiza ekwenzeni ngcono indawo etholakala ngaphakathi kwesakhiwo ngoba asebenza endaweni ephakeme, eshiya isikhala sendawo yokusebenza eminye imisebenzi.
Ngamafuphi, ama-bridge cranes angamathuluzi abalulekile ekusebenzeni kwezimboni, ahlinzeka ngamakhono okuphatha izinto asebenzayo futhi anokwethenjelwa. Amabhizinisi afuna ukuthuthukisa izinqubo zawo zokuphakamisa nokuphatha izinto kufanele acabangele ukutshala imali ku-overhead crane esezingeni eliphezulu evela enkampanini ethembekile ye-overhead crane. Ngemishini efanele, izinkampani zingakhulisa ukusebenza kahle kokusebenza futhi zigcine indawo yokusebenza iphephile.
