Kunezinhlobo eziningi zokulingisa, ngakho umshini wokuqhumisa isibhamu nawo uhlukile. Okulandelayo yizimiso ezijwayelekile zokukhetha umshini wokuqhumisa isibhamu wokulingisa:
1. Izici zokulingisa (usayizi, ikhwalithi, ukwakheka kanye nezinto ezibonakalayo, njll.) Usayizi weqoqo lokukhiqiza, uhlobo lokulingisa kanye nezidingo zokusebenzisa kuyisisekelo esiyinhloko sokukhetha umshini wokuqhumisa isibhamu;
2. Ukunqunywa komshini wokuqhumisa isibhamu kuzocatshangelwa kanye nenqubo yokukhiqiza ngaphambi kokuhlanza. Ingaphezulu le-castings lizohlanzwa ngemuva kokuqhunyiswa kwesihlabathi ngangokunokwenzeka ukuze kwakhiwe izimo ezivumayo zokuhlanza. Lapho inqubo yokudubula nokukhishwa kwesihlabathi yamukelwa, ekukhiqizeni inqwaba, ukukhishwa kwesihlabathi nokuhlanza indawo kufanele kuhlukaniswe izinqubo ezimbili, ezenziwa ngamasethi amabili emishini;
3. Ukususwa kwesihlabathi se-Electro-hydraulic kungasetshenziselwa ukukhishwa kwe-investment ngokukhipha isihlabathi okunzima nokukhipha okunomgodi ongaphakathi oyinkimbinkimbi kanye nokususwa okunzima komgogodla; Ngokusakazwa okunomgodi wangaphakathi oyinkimbinkimbi futhi omncane kanye nezidingo zokuhlanzeka okuphezulu, njengezingxenye ze-hydraulic kanye nama-valve castings, ukuhlanzwa kwe-electrochemical kulula ukukusebenzisa;
4. Ngemicimbi yokukhiqiza ehlukahlukene kanye namaqoqo amancane, okokusebenza kokuhlanza noma izinhlobo ezimbili zamadivayisi okuphatha avumelana nezimo eziqinile kusayizi wokulingisa kufanele kukhethwe; Ngezikhathi zokukhiqiza ezinezinhlobo ezimbalwa nenani elikhulu, umshini wokuqhumisa ophumelelayo noma okhethekile kufanele kukhethwe;
Lapho kokubili ukuhlanza okomile nokuhlanza okumanzi kungahlangabezana nezidingo zokuhlanza, okubaluleke kakhulu kufanele kunikezwe ukuhlanza okomile okungakhiqizi indle; Lapho ukuhlanza okomile, umshini wokuqhumisa odubulayo osebenza kahle kakhulu kanye nokusetshenziswa kwamandla aphansi kufanele kucatshangelwe kuqala. Ngokusakazwa okunendawo eyinkimbinkimbi kanye ne-cage, uhlobo lwe-squirrel-cage, uhlobo lwe-manipulator kanye nohlobo lwe-hook yokudubula imishini ekwazi ukushwiba noma ukunyakaza ngesikhathi sokuhlanza ingakhethwa ngokuya ngosayizi neqoqo lokukhiqiza lokulingisa.
