Magiya a helical olondola kwambiri ndi zinthu zofunika kwambiri m'mabokosi amagetsi a mafakitale, opangidwa kuti azipereka mphamvu bwino komanso moyenera. Magiyawa ali ndi mano aang'ono omwe amalowa pang'onopang'ono, amachepetsa phokoso ndi kugwedezeka, kuonetsetsa kuti akugwira ntchito mwakachetechete.
Zopangidwa kuchokera kumphamvu kwambiri, zotayira zosamva kuvala komanso zokhazikika mpaka momwe zimatchulidwira, zimapereka kulimba kwapadera komanso kudalirika. Zoyenera kugwiritsa ntchito zolemetsa, magiya olondola kwambiri a helical amathandizira ma gearbox akumafakitale kuti azitha kunyamula katundu wambiri wa torque ndikutaya mphamvu pang'ono, zomwe zimathandizira magwiridwe antchito onse komanso moyo wautali wamakina m'malo ovuta.
