Bridge crane ndi chida chofunikira chonyamulira chopangidwa ndi mlatho, makina onyamulira, ndi zida zamagetsi. Makina ake onyamulira amatha kuyenda mopingasa pamlatho ndikuchita ntchito zokweza m'malo atatu. Crane za mlatho zimagwiritsidwa ntchito kwambiri popanga mafakitale amakono. Ubwino wake waukulu ndikutha kumaliza kuyimitsidwa kwazinthu zolemetsa, kuyenda kopingasa, komanso kukweza kokweza. Izi zimathandizira kwambiri kupanga bwino komanso kumachepetsa kuchuluka kwa ntchito.
Mlatho wa abridge cranenthawi zambiri amapangidwa ndi zitsulo, zomwe zimakhala ndi mphamvu zabwino komanso zokhazikika ndipo zimatha kupirira katundu waukulu. Makina onyamulira amaphatikizapo zinthu monga mtengo waukulu, trolley, ndi zida zonyamulira. Pali galimoto yaing'ono yomwe imayikidwa pamtengo waukulu, yomwe imatha kuyenda motsatira mtengo waukulu. Slings amagwiritsidwa ntchito popachika zinthu. Zida zamagetsi zimaphatikizapo ma mota, zingwe, mabokosi owongolera, ndi zina zambiri, zomwe zimagwiritsidwa ntchito kuyendetsa makina okweza ndikukwaniritsa ntchito zowongolera kutali.
Ubwino wa cranes wa mlatho umawonekera makamaka pazinthu izi:
Choyamba, ma cranes a mlatho amatha kukwaniritsa mphamvu zambiri komanso kukweza moyenera. Kutha kupachika zinthu zolemera komanso kukweza mopingasa komanso moyima mu danga la mbali zitatu. Oyenera mitundu yosiyanasiyana ya zochitika zopanga mafakitale.
Kachiwiri, ma cranes a mlatho amakhala ndi chitetezo chabwino kwambiri. Mapangidwe ake ndi omveka, ndipo zigawo zosiyanasiyana zimagwirizana kwambiri, kuonetsetsa kuti palibe ngozi zachitetezo zomwe zimachitika panthawi yokweza.
Komanso, phokoso ntchito ndi kugwedera wamilatho cranesndi otsika. Itha kuchepetsa phokoso lachilengedwe m'mafakitole, malo osungiramo katundu, ndi malo ena antchito, kuwonetsetsa kuti malo ogwira ntchito abata komanso omasuka.
Pomaliza, ma cranes a mlatho amagwiritsidwa ntchito kwambiri popanga, mayendedwe, madoko, kupanga zombo ndi zina. Amagwiritsidwanso ntchito kwambiri m'mafakitale monga magalimoto, zomanga zombo, zitsulo, ndi simenti. Ndi chitukuko chaukadaulo, ukadaulo wa crane mlatho ukukulanso mosalekeza, ndikuchita bwino kwambiri komanso mwayi wogwiritsa ntchito zambiri.
