1. Ukusebenza kahle okuphezulu
Ngenxa yokusebenzisa amasilinda amaningi asebenza ngogesi ukuze akhe ilunga elifana nomshini wokuxhuma ingalo elolini eligoqekayo eligibele izintambo, ingaqeda ukunyakaza kwayo ngokushesha futhi isebenze ngokuphumelelayo.
Izinga nalo liphakeme.
2. Izingalo ezigoqayo zifaneleka kakhulu ezindaweni zokusebenza eziwumngcingo
Lokhu kunqunywa isakhiwo sayo.I-crane yengalo egoqekayo egibele ifaneleka kakhulu ezindaweni zokusebenza eziwumngcingo ezifana nezindawo zokugcina izimpahla zasefekthri, kuyilapho ingalo eqondile ifaneleka kakhulu ngenxa yesakhiwo sayo.
Isikhala esidingekayo sokuphakelwa sikhulu.
3. Ingalo egoqayo ithatha isikhala esincane kuyo yonke imoto
Ukusebenza kwesikhala kucacile uma uthi nhlá, futhi i-crane egoqiwe ingalo ingakwazi ukuhoxisa ingalo yonke ye-crane ngesikhathi sokuthuthwa kwempahla, okuholela esikhaleni esincane uma kuqhathaniswa.
I-crane egibele iloli yengalo eqondile ingabekwa ivundlile kuphela, futhi isikhala esithathwa yimoto ngesikhathi sokushayela sisikhulu uma kuqhathaniswa.
