Iikhreyini eziphakamileyo kunye nephezulu ziindidi ezimbini zezixhobo zokuphakamisa ezisetyenziswa kwizicelo ezahlukeneyo zamashishini.Zombini iikhreyini kunye neekhreyini ezingaphezulu zisetyenziselwa ukuphakamisa nokuhambisa imithwalo enzima;kunjalo, kukho umahluko phakathi kwezi ntlobo zimbini zezixhobo zokuphakamisa.Okulandelayo ngomnye umahluko ophambili phakathi kweekhreyini kunye neekhreyini eziphezulu: 1. Umsebenzi I-hoist sisixhobo sokuphakamisa esisetyenziselwa ukunyusa ngokuthe nkqo kunye nokwehlisa imithwalo.Iihoists zihlala zisetyenziswa kwiindawo ezincinci kwaye zixhonywe kwiindawo ezisisigxina okanye kwiidoli ezihambayo.Zingasetyenziselwa ukuphakamisa imithwalo ukusuka kwiikhilogram ezimbalwa ukuya kwiitoni ezininzi, kuxhomekeke kumthamo wabo.Kwelinye icala, i-crane ephezulu ngumatshini ontsonkothileyo osetyenziselwa ukuhambisa imithwalo ngokuthe tye nangokuthe nkqo.Njengee-hoists, iikhreyini ezihamba phezulu zinokunyusa imithwalo ukusuka kwiikhilogram ezimbalwa ukuya kwiitoni ezininzi.Zihlala zisetyenziswa kwiindawo ezinkulu zemizi-mveliso ezifana neendawo zokugcina iimpahla, iifektri kunye neendawo zeenqanawa.2. IiCranes zokuyila zilula kuyilo, zineentambo okanye amatyathanga ancanyathiselwe kwiimotor okanye iikranki zesandla zokuphakamisa okanye ukuthoba imithwalo.I-Cranes ingaba ngumbane okanye iqhutywe ngesandla.I-crane ephezulu ngumatshini onzima ngakumbi obandakanya ibhulorho, itroli kunye ne-hoist.Iibhulorho ziyimiqadi ethe tye ehamba kwindawo yokusebenza kwaye ixhaswa ngamakholomu okanye iindonga.I-trolley yiqonga elihambahambayo eliphantsi kwebhulorho ethwele i-hoist.Njengoko kukhankanyiwe ngaphambili, ii-hoists zisetyenziselwa ukuphakamisa nokunciphisa imithwalo.3. Ukuzilolonga IiCranes zihlala zimile okanye zihamba ngendlela ethe tye.Ziyilelwe ukuphakamisa imithwalo ngokuthe nkqo okanye ukuhambisa imithwalo ngemigama ethe tye.IiCranes zinokuxhonywa kwiitroli ukubonelela ngenqanaba elithile lokushukuma, kodwa ukuhamba kwazo kusakhawulelwe kwindlela echaziweyo.Iikhreyini ezingaphezulu, kwelinye icala, ziyilelwe ukuba zihambe ngokuthe tye kwaye ngokuthe nkqo.Ibhulorho ye-crane inokushukunyiswa ngobude bendawo yokusebenza, ngelixa itroli inokushukunyiswa ngobubanzi.Oku kuvumela i-crane ephezulu ukubeka umthwalo kwiindawo ezahlukeneyo ngaphakathi kwendawo yokusebenza.4. Ii-Capacity Hoists kunye nee-cranes eziphezulu ziza ngeendlela ezahlukeneyo zokuphakamisa ukuhlangabezana neemfuno zezicelo ezahlukeneyo zemizi-mveliso.IiCranes zithatha umthamo ukusuka kumakhulu ambalwa eeponti ukuya kwiitoni ezininzi.Iikhreyini ezingaphezulu zihamba ngomthamo ukusuka kwitoni enye ukuya ngaphezulu kweetoni ezingama-500 kwaye zilungele ukuhambisa imithwalo enzima kakhulu.Isishwankathelo, zombini ii-hoists kunye neecranes ezingaphezulu zibalulekile izixhobo zokuphakamisa ezisetyenziswa kwizicelo ezahlukeneyo zoshishino.Ngelixa iikhreyini ziyilelwe ngokuyintloko ukuphakamisa kunye nokuthoba imithwalo ngokuthe nkqo, iikhreyini ezingaphezulu ziyakwazi ukuhambisa imithwalo ngokuthe tye nangokuthe nkqo.Kwakhona, uyilo kunye nokuphakamisa amandla eekhreyini ezingaphezulu kubenza bafaneleke ngcono kwiindawo ezinkulu zemizi-mveliso, ngelixa ii-hoists zilukhetho olungcono lweendawo ezincinci ezifuna kuphela ukuphakanyiswa ngokuthe nkqo.
