Crane pamwamba(crane ya mlatho, EOT crane) imapangidwa ndi mlatho, njira zoyendera, trolley, zida zamagetsi. Mlatho wa mlatho umatengera kapangidwe ka bokosi, makina oyendayenda a crane amatengera magalimoto osiyana ndi mota ndi liwiro lotsitsa. Amadziwika ndi kapangidwe koyenera komanso chitsulo champhamvu kwambiri chonse.

Zida Zachitetezo za Bridge Cranes
Kuwonetsetsa kuti ma cranes a hook Bridge akugwira ntchito motetezeka komanso kupewa ngozi, zida zingapo zodzitchinjiriza zimayikidwa:
Katundu Limiter: Imaletsa kuchulukitsidwa, chomwe chimayambitsa ngozi za crane.
Zosintha Zochepa: Kumaphatikizapo malire a maulendo okwera ndi otsika a njira zokwezera, komanso malire a maulendo a trolley ndi bridge.
Zosungira: Tengani mphamvu ya kinetic pakuyenda kwa trolley kuti muchepetse mphamvu.
Zida Zotsutsana ndi Kugunda: Pewani kugundana pakati pa ma cranes angapo omwe akugwira ntchito panjira imodzi.
Anti-Skew Zipangizo: Chepetsani kusokonekera komwe kumachitika chifukwa cha kupanga kapena kuyika zolakwika, kupewa kuwonongeka kwamapangidwe.
Zida Zina Zachitetezo: Zivundikiro za mvula pazida zamagetsi, zotchingira zotchingira zayatsidwaSingle-girder bridge cranes, ndi njira zina kuonetsetsa chitetezo ntchito.
