Yintoni i-Double Girder Bridge Crane?

A I-Crane yeBhulorho ephindwe kabiniluhlobo lwekreyini ephezu komhlaba enezikhonkwane ezimbini ezilinganayo (iimitha ezithe tye) ezixhasa inkqubo yokuphakamisa kunye netroli yekreyini. Olu yilo lubonelela ngeenzuzo ezininzi, nto leyo eyenza ukuba ifaneleke kwiindlela ezahlukeneyo zokusebenza kwemizi-mveliso. Nazi ezinye zeempawu eziphambili kunye neenzuzo:

Ezona mpawu:
Ulwakhiwo:

IiGirder ezimbini: Uyilo lwegirder ezimbini luvumela ububanzi obubanzi kunye nomthamo omkhulu wokuphakamisa xa kuthelekiswa neecrane zegirder enye.
Inkqubo yeTroli: Isinyusi sihamba ecaleni kwegirders, sivumela ukuphakamisa ngokuthe nkqo kunye nokuhamba ngokuthe tye.
Umthamo wokuphakamisa:

Ngokwesiqhelo, ii-crane ezi-double girder zinokuthwala imithwalo enzima, zihlala zidlula amandla ee-crane ezi-single girder.
Ukususwa kobude:

Uyilo luvumela indawo engaphezulu yentloko, nto leyo eluncedo ekuphakamiseni izinto ezinde okanye kwimisebenzi efuna indawo ethe nkqo.
Ukuguquguquka:

Zinokuxhotyiswa ngee-hoists ezahlukeneyo kunye neziqhoboshelo, nto leyo ezenza zilungele iintlobo ezahlukeneyo zezinto kunye nokusetyenziswa kwazo.
Uzinzo:

Ulwakhiwo lwe-double girder lubonelela ngozinzo oluphuculweyo kunye nokuqina, lunciphisa ukushukuma kwaye luphucula ukhuseleko ngexesha lokusebenza.
Izicelo:
Iikhreyini zebhulorho ezijikelezileyo zisetyenziswa kakhulu kwezi:

Iindawo zokwenza imveliso
Iivenkile zokugcina impahla
Iindawo zokuthumela nezokwamkela
Iifektri zentsimbi
Iindawo zokwakha
Isiphelo:
Lilonke, iikhreyini zebhulorho eziphindwe kabini zisisombululo esomeleleyo nesisebenziseka lula sokuphakamisa izinto ezinzima kunye nokuphatha izinto kwiindawo ezahlukeneyo zoshishino, zibonelela ngomthamo ophuculweyo, uzinzo, kunye nokusebenza kakuhle.
