II-crane ye-double girder overheadsisisombululo esinzima sokuphakamisa izinto esisetyenziswa ngokuqhelekileyo kumashishini afuna ukuqina, ukuphatha izinto eziphathekayo. Olu hlobo lwekhreyini luqulathe iibhanti ezimbini ezihambelanayo ezithatha ububanzi bendawo yokusebenza, zinika uzinzo olukhulu kunye nomthamo wokuthwala umthwalo kune-cranes enye. Ezi cranes eziphezulu zifanelekile kwizicelo ezifana nokuveliswa kwentsimbi, ukudibanisa iimoto, ukwakhiwa kweenqanawa, kunye nezinye iindawo ezifunwa kakhulu apho ukuchaneka kunye nokuqina kubalulekile.
Xa uqwalasela izisombululo zokuphakamisa umsebenzi onzima, ukuqonda iumbhinqo kabiniewe ixabiso craneibalulekile kuhlahlo lwabiwo-mali lweeprojekthi zemizi-mveliso emikhulu.
Ubume be-aI-crane ye-double girder overheadngokuqhelekileyo ibandakanya:
Iigida ezimbini: Iibhanti ezimbini eziphambili ezithwala umthwalo, zinika i-crane umthamo ophezulu wokuphakamisa izinto ezinzima.
Iilori zokuphela: Zibekwe eziphelweni zeebhanti, ezi ziququzelela intshukumo ecaleni komgaqo weenqwelo-moya we-double girder eot crane, zenza ukuba uhambo oluthe tyaba lunqumle indawo yokusebenza.
I-Hoist kunye ne-Trolley: Ibekwe phakathi kweebhanti ezimbini, i-hoist kunye netroli zihamba kunye ne-span yeebhanti, zivumela ukuhamba komthwalo othe nkqo kunye othe tye.
IiMoto zoMbane kunye neNkqubo yoLawulo: Ii-double girder eot craneintshukumo, ukunyuswa, kunye neminye imisebenzi ilawulwa ngenjini yombane, rhoqo ngolawulo olukude okanye lukanomathotholo ukuze lusebenze ngokukhuselekileyo nangempumelelo.
Iumbhinqo kabiniewe ixabiso craneinokwahluka ngokubanzi ngokuxhomekeke kwiinkcukacha ezifana nomthamo womthwalo, ubude bexesha, kunye nokhetho lokwenziwa ngokwezifiso.
Ukugcinwa rhoqo kwamacandelo e-crane-ezifana ne-hoist, iisistim zolawulo, kunye nesakhelo sesakhiwo-ibalulekile ekusebenzeni ngokukhuselekileyo nangempumelelo. Iishedyuli zogcino kufuneka zibandakanye ukuhlolwa kwemoto, iisistim zebrake, kunye neendawo ezithwele umthwalo ukuqinisekisa ukuthembeka nokuthintela ukophuka okungalindelekanga.
