Mfundo Yogwirira Ntchito
Ntchito ya ancrane yapansi panthakazimatengera njira zingapo zogwirizana:
1.Kukweza:

2.Kusuntha Kwam'mbali:
Trolley, yomwe imanyamula chokwezera, imayenda motsatira chotchinga chachikulu, ndikuyika katunduyo pamalo omwe akufuna.
3.Kuyenda:
Crane yonse imayenda motsatira mizati ya msewu wonyamukira ndegeyo, kupangitsa kuti katunduyo ayendetsedwe bwino pamalo ogwirira ntchito.
4.Kutsitsa:
Ikangokhazikika, chokwezacho chimatsitsa katunduyo pansi kapena pamalo osankhidwa, kumaliza ntchito yosamalira zinthu.
Ma cranes okwera pansi amapereka njira zogwirira ntchito bwino m'malo omwe machitidwe okhazikika pansi ndi osatheka, omwe amapereka kusinthasintha komanso kugwiritsa ntchito moyenera malo oyimirira.
