I-double girderphezulu ama-cranesingakwazi ukuphatha imithwalo esindayo ngokuphepha nangokunembile. Okukabili ibhandephezulu I-crane inokusebenza okuphakeme, ukwakheka okuhlangene, isisindo esilula, ukwethembeka nokusebenza, futhi ingahlangabezana nezimo ezihlukahlukene zokusebenza. Inganciphisa ukutshalwa kwezimali okuphelele efekthri, ithuthukise ukusebenza kahle kokukhiqiza, inciphise izindleko zokulungisa, futhi yonge ukusetshenziswa kwamandla okusebenza.
Izici ze-double girder overhead crane:
Isakhiwo esihlangene, ukugcinwa okulula, ukusetshenziswa kwamandla okuphansi kanye nobubanzi bejubane elibanzi.
Ibhuleki eligijima libushelelezi futhi linciphisa ngempumelelo ukunyakaziswa kwezinto ezisindayo, linciphisa ukushwibeka komthwalo, futhi lithuthukise ukusebenza kahle kokuphakamisa.
Di-ouble girder overhead crane yi fi-lexible, iguquguquka ngokusebenzisa okuhlukile kokufaka.
Ukugcinwa okuphansi, idrayivu eqondile enomsindo ophansi ene-disc brake ne-centrifugal mass.
Inethiwekhi yomhlaba wonke yozakwethu abaqinisekisiwe, abakhiqizi be-crane nabakhi bohlelo.
Ngaphambi kokusebenzisa i-I-double girder bridge crane:
Qiniseka ukuthi ubheka izisakazi ezahlukahlukene ngaphambi komsebenzi. Qiniseka ukuthi izisakazi ziphelele futhi aziphelele. Umait inesici, ngeke kwenzeke ukusebenza njenge-crane.
Bheka isimo sentambo. Qinisekisa intambokweI-crane engaphezu kwamathani ayi-10 ivikelekile futhi ayikhululekile noma ayiphukile. Uma ubopha into ngomphetho, udinga ukufaka isivikelo phakathi kwento nentambo ukuvimbela intambo ukuthi ingagqabhuki.
Thola isikhungo sobunzima besisindo. Lokhu kungagwema ukwenzeka kokudonsa kwe-diagonal, futhi izinto ezikhethekile zokuphakamisa zidinga abasebenzi ukuthi basebenze.
Lapho uphakamisa izinto, ungajahi. Qiniseka ukuthi ulinda isikhashana ukuze izimpahla zizinze ngaphambi kokuqhubeka. Ayikho imfucumfucu evunyelwe ezintweni ezisindayo, futhi akekho ovunyelwe ukuma phezu kwazo. Niniusebenzisa amathani ayi-10i-crane ephezulu to phakamisa izimpahla, abasebenzi abangabalulekile abavunyelwe ukuthi badlule ngaphansi kwento.
Izinyathelo zokuphepha emsebenzini kufanele zithuthukiswe. Isibonelo, abasebenzi kufanele bagqoke izigqoko zokuzivikela, ochwepheshe kufanele banikeze umyalo obumbene, futhi iminyango ehlukahlukene kufanele iqondise umsebenzi wabo. Uma into iphakanyiswa phansi, hlola ukuthi intambo yocingo nezinye izingxenye ziphephile yini. Uma kungaphephile, yeka i-i-double girder overhead craneukuze zihlolwe.
