Igishushanyo mbonera cya kabiri gishobora kuba igiciro cyiza kuri crane iremereye cyane mubikorwa, mububiko, cyangwa aho bateranira. Crane isaba ubushobozi buhanitse, kwaguka kwagutse, cyangwa uburebure bwo hejuru bwo hejuru byungukirwa nigishushanyo mbonera cya kabiri, ariko birashobora gutwara byinshi imbere.
Ikiraro cyikubye kabiri kirasaba kwemererwa hejuru hejuru ya crane kurwego rwo hejuru, kuko amakamyo azamura hejuru yumukandara kumurongo wa crane.

Imiterere shingiro yubucuruzi bubiri bwibiraro byubucuruzi ni, amakamyo agenda kumuhanda urambura uburebure bwa sisitemu yumuhanda, hamwe nikiraro-gare-umukandara washyizwe kumamodoka yanyuma, aho trolley yo kuzamura ihagarika lift ikagenda hejuru ikiraro. Ikiraro cya kabili-kiraro kigizwe nibiti bibiri byikiraro bifatanye kumuhanda, mubisanzwe bitangwa hejuru yumuriro wamashanyarazi wamashanyarazi, ariko birashobora no gutangwa hejuru yumurongo wamashanyarazi ukoresheje amashanyarazi. SEVENCRANE Hejuru ya Cranes hamwe na Hoist irashobora gutanga ikiraro cyoroshye cya kiraro cyikiraro gikoreshwa muri rusange, kandi ikanatanga ibicuruzwa byubatswe byubatswe byubatswe kabiri byinganda zitandukanye. Kuberako swivels ishobora kwicara hagati cyangwa hejuru yumurongo wambukiranya, iyindi 18-36 yuburebure bwa swivel iraboneka mugihe ukoresheje ikiraro cya kiraro cya kabiri.
