A I-crane ye-double girder overheadluhlobo lwekhreyini eneebhanti ezimbini zebhulorho (ekwabizwa ngokuba yimiqadi enqamlezileyo) apho umatshini wokunyuselwa kunye netroli zihamba. Olu luyilo lunikeza amandla aphezulu okuphakamisa, ukuzinza kunye nokuguquguquka xa kuthelekiswa ne-cranes eyodwa-girder. Iicranes eziphindwe kabini zisoloko zisetyenziselwa ukuphatha imithwalo enzima kunye nezicelo ezifuna ukubekwa okuchanekileyo kwezinto.
Iimpawu zeI-crane ye-double girder overhead:
Iindlela zokunyusa kunye nokuqhuba zenziwe ngokwemodyuli ukuze kuqinisekiswe ukuchaneka kunye nokuguquguquka kwecandelo ngalinye, kunye neekhonkco ezimbalwa zokuhambisa, ukusebenza okuphezulu, izinga lokungaphumeleli eliphantsi, kunye nokuhlanganisa ngokukhawuleza.
Isakhiwo esinomthwalo onzima sinamandla, sihlala sihlala, kwaye sinomthwalo omkhulu wokuthwala umthwalo, onokuqhelana neemeko zokusebenza ezinzima.
Ihuku kunye nesixhobo sokuxhoma ziqhagamshelwe ngokulula ukuze zitshintshwe ngokukhawuleza.
Umatshini wonke uguquguqukayo wesantya solawulo, ngokuqala okugudileyo kunye nokuqhobosha, ukhuselekile kwaye kulula ukuwusebenzisa.
Amacandelo akumgangatho ophezulu asetyenziswa, kunye nokugcinwa okuphantsi kunye nobomi benkonzo ende.
