Ama-crane okuphakamisa kanye nama-overhead ayizinhlobo ezimbili zemishini yokuphakamisa esetshenziswa ezinhlotsheni ezahlukene zezimboni. Womabili ama-crane kanye nama-crane aphezulu asetshenziselwa ukuphakamisa nokuhambisa imithwalo esindayo; nokho, kukhona umehluko phakathi kwalezi zinhlobo ezimbili zemishini yokuphakamisa. Okulandelayo eminye yemehluko emikhulu phakathi kwama-crane nama-crane aphezulu: 1. Umsebenzi I-hoist iyithuluzi lokuphakamisa elisetshenziswa kakhulu ekuphakamiseni okuqondile kanye nokwehlisa imithwalo. Ama-hoist avame ukusetshenziswa ezindaweni ezincane futhi afakwa ezindaweni eziqondile noma kuma-dollies ahambayo. Angasetshenziswa ukuphakamisa imithwalo esukela kumakhilogremu ambalwa kuya kumathani amaningana, kuye ngokuthi angakanani. Ngakolunye uhlangothi, i-overhead crane ingumshini oyinkimbinkimbi osetshenziselwa ukuhambisa imithwalo kokubili ngokuvundlile nangokuqondile. Njenge-hoists, ama-overhead crane angaphakamisa imithwalo esukela kumakhilogremu ambalwa kuya kumathani amaningana. Avame ukusetshenziswa ezindaweni ezinkulu zezimboni njengezindawo zokugcina impahla, amafektri kanye nezindawo zokuthutha imikhumbi. 2. Ama-Crane Okuklama alula kakhulu ekuklanyweni, anezintambo noma amaketanga anamathiselwe kuma-motor noma ama-crank esandla okuphakamisa noma ukwehlisa imithwalo. Ama-crane angaba ngogesi noma asetshenziswe ngesandla. I-overhead crane ingumshini oyinkimbinkimbi kakhulu oqukethe ibhuloho, i-trolley kanye ne-hoist. Amabhuloho ayimishayo evundlile ehlanganisa indawo yokusebenza futhi asekelwa ngamakholomu noma izindonga. I-trolley iyipulatifomu ehambayo etholakala ngaphansi kwebhuloho elithwala i-hoist. Njengoba kushiwo ngaphambili, ama-hoist asetshenziselwa ukuphakamisa nokwehlisa imithwalo. 3. Ukuzivocavoca Ama-Crane avame ukuma noma ahambe ngendlela eqondile. Aklanyelwe ukuphakamisa imithwalo ngokuqondile noma ukuhambisa imithwalo ebangeni elivundlile. Ama-Crane angafakwa kuma-trolley ukuze anikeze izinga elithile lokuhamba, kodwa ukunyakaza kwawo kusalinganiselwe endleleni echaziwe. Ama-crane angaphezulu, ngakolunye uhlangothi, aklanyelwe ukuhamba ngokuvundlile nangokuvundlile. Ibhuloho le-crane lingahanjiswa ngobude bendawo yokusebenza, kuyilapho i-trolley ingahanjiswa ngobubanzi. Lokhu kuvumela i-crane engenhla ukuthi ibeke umthwalo ezindaweni ezahlukene ngaphakathi kwendawo yokusebenza. 4. Amandla Ama-Hoist nama-crane angaphezulu afika ngamakhono ahlukene okuphakamisa ukuze ahlangabezane nezidingo zezicelo ezahlukahlukene zezimboni. Ama-crane asukela kumakhulu ambalwa amakhilogremu kuya kumathani amaningana. Ama-crane angaphezulu asukela ku-1 ton kuya kumathani angaphezu kwama-500 futhi alungele ukuhambisa imithwalo esindayo kakhulu. Ngamafuphi, kokubili ama-hoist kanye nama-overhead cranes ayimishini ebalulekile yokuphakamisa esetshenziswa ezinhlotsheni ezahlukene zezimboni. Ngenkathi ama-cranes eklanyelwe ngokuyinhloko ukuphakamisa nokwehlisa imithwalo eqonde phezulu, ama-overhead cranes ayakwazi ukuhambisa imithwalo eqonde phezulu naphezulu. Futhi, ukwakheka kanye nomthamo wokuphakamisa wama-overhead cranes kuwenza afaneleke kangcono ezindaweni ezinkulu zezimboni, kuyilapho ama-hoist eyindlela engcono yezindawo ezincane ezidinga kuphela ukuphakamisa eqonde phezulu.
