Byakozwe byumwihariko kuri SANY nubwoko butandukanye bwibikoresho byo guterura, iki nigikoresho cyibanze cyumutekano kugirango wirinde kurenza urugero no kurinda umutekano wubwubatsi.

Iki gicuruzwa nicyambere cyuruganda rwahujwe nuburebure (anti-overinding switch) kuri kamyo yikamyo ya SANY, yabugenewe kubikorwa bya crane itekanye. Iyo ifuni izamutse igera ku burebure bwateganijwe, igikoresho gihita gihagarika umuzunguruko wo kuzamura kandi kigatera impuruza yumvikana-igaragara, ikumira impanuka z'umutekano nko gufatira hejuru no gucika umugozi. Nibikoresho byingirakamaro birinda umutekano kubikorwa byo guterura.

SANY GJ-1 Overwind Switch ni igikoresho cyo kurinda umutekano cyagenewe cyane cyane kuzamura imashini. Mugukurikirana-mugihe nyacyo umwanya ufatika, ihita igabanya umuvuduko wo kugenzura kuzamura mugihe uburebure bwateganijwe bwagerwaho, bikumira byimazeyo impanuka nkumugozi wicyuma cyizuba, kumeneka no gufatira hejuru. Itanga uburinzi bwizewe kubikoresho n'umutekano w'abakozi. Iki gicuruzwa kirahujwe nuruhererekane rwose rwa SANY crane, crawler crane, amakamyo yikamyo nibikoresho bizamura ibyambu, bigaragaramo urwego rwo hejuru rwo kurinda hamwe nubushobozi bukomeye bwo kurwanya kwivanga kugirango bihuze nibikorwa bitandukanye bigoye.
