Crane ifunga hamwe nugukingira umutekano nibintu byingenzi byerekana umutekano mubikorwa byo guterura kijyambere, kandi kubikoresha bikoresha inganda zose n’inganda aho usanga hari ibyago byo gufata imitwaro. Ahantu hubatswe, bikoreshwa mukuzamura neza ibyuma byibyuma, ibice byabugenewe, nibikoresho biremereye, birinda impanuka ziterwa no kunyeganyega hejuru. Ku byambu no ku kivuko, bareba neza ko kontineri n'imizigo iremereye bifunze neza mu gihe cyo guterura, kugenda, no gutwara ubwato. Mu mahugurwa y’uruganda, batanga umutekano wihariye wo gutunganya ibicapo, ibyuma, hamwe n’ibikorwa binini ku murongo w’ibicuruzwa, bikumira impanuka ziterwa n’ingaruka cyangwa uburangare. Mu mishinga idasanzwe nk'ingufu z'umuyaga no kubaka ikiraro, zihura n'ubutumburuke bwo hejuru, agaciro gakomeye, hamwe n’ibihe bishobora guteza ibyago byinshi, inkoni zifunze ni amahame y’umutekano ateganijwe asabwa n’amabwiriza. Igishushanyo cyabo "gufungura intoki, gufunga byikora " byubaka ubwirinzi bwumubiri bwizewe kubintu bitandukanye bigenda bitera imbaraga kandi bigoye, bigatuma biba ibikoresho byingenzi byingirakamaro kugirango bagere ku musaruro utekanye.
