Mmodzi mwa ubwino waukulu wapamwamba kuthamanga mlatho cranesndi chakuti amatha kupangidwa kuti azigwira ntchito zolemetsa kwambiri. Mwakutero, amakhala okulirapo kuposa ma crane a masheya, kotero sikuti amatha kukhala ndi mwayi wokwera kwambiri kuposa ma cranes, komanso amatha kukhala ndi mipata yotakata pakati pa mizati ya njanji chifukwa chakukula kwa mamembala omwe amapanga dongosolo.
Kuyika trolley ya crane pamwamba pa matabwa a mlatho kumaperekanso zopindulitsa kuchokera kumawonedwe okonza, kumathandizira kupeza mosavuta ndi kukonza. Thepamwamba akuthamanga single girder craneamakhala pamwamba pa matabwa a mlatho, kotero ogwira ntchito yokonza amatha kuchita zofunikira pa malo malinga ngati pali njira kapena njira zina zopezera malo.
Nthawi zina, kukwera trolley pamwamba pa mizati ya mlatho kumatha kulepheretsa kuyenda m'malo onse. Mwachitsanzo, ngati denga la malo liri lotsetsereka ndipo mlatho uli pafupi ndi denga, mtunda umene pamwamba pa girder crane ukhoza kufika kuchokera pamzere wa denga ndipo khoma likhoza kukhala lochepa, kuchepetsa malo omwe crane ikukwera. ikhoza kubisala mkati mwa malo onse opangira.
Ma cranes okwera pamwambakuthamanga pa njanji yokhazikika yokwera pamwamba pa mtengo uliwonse wa msewu wonyamukira ndege, womwe umalola magalimoto otsiriza kunyamula girder ndikukwera pamwamba. Ma cranes awa amatha kukhazikitsidwa ngati matabwa amodzi kapena awiri, kutengera zomwe mukufuna.
Zina mwa ubwino waukulu wapamwamba kuthamanga mlatho craneszikuphatikizapo:
Palibe mphamvu zoletsedwa. Zimenezi zimathandiza kuti azitha kunyamula katundu ang'onoang'ono ndi aakulu.
Kuchulukitsa kukweza kutalika. Kukwera pamwamba pa mtengo uliwonse wa njanji kumawonjezera kutalika kokweza, komwe kumapindulitsa m'nyumba zomwe zili ndi mutu wocheperako.
Kuyika kosavuta. Popeza kuti chiwombankhanga chokwera pamwamba chimathandizidwa ndi matabwa a njanji, chinthu cholendewera cholendewera chimachotsedwa, ndikupangitsa kukhazikitsa kosavuta.
Kusamalira kochepa. M'kupita kwa nthawi, pamwamba kuthamanga mlatho crane safuna kukonzanso kwambiri, kupatula macheke pafupipafupi kuonetsetsa kuti njanji ali bwinobwino ndipo ngati pali nkhani.
