Ikhreyini engaphezulu kwebhanti ekwaziyo ukuphakamisa izinto ezinzima ezahlukeneyo

Amacandelo kunye noMgaqo-siseko wokuSebenza weCrane yoMntla weGirder enye:

1. I-Single Girder: Isakhiwo esiphambili se-crane enye yegirder phezu kwentloko yintsimbi enye ejikeleza indawo yokusebenza. Ngokuqhelekileyo yenziwe ngentsimbi kwaye ibonelela ngenkxaso kunye nomkhondo wamacandelo e-crane ukuhamba kunye.
2. I-Hoist: I-hoist licandelo eliphakamisayo le-crane. Iqukethe i-motor, i-drum okanye i-pulley system, kunye ne-hook okanye i-attachment yokuphakamisa. I-hoist inoxanduva lokuphakamisa kunye nokunciphisa imithwalo.
3. Iikhareji zokuphela: Iikhareji zokuphela zibekwe macala omabini ejida enye kwaye zibeke amavili okanye iirola ezivumela i-crane ukuba ihambe ecaleni kwendlela yeenqwelo-moya. Baxhotyiswe ngemoto kunye nesixhobo sokuqhuba ukubonelela ngentshukumo ethe tye.
4. Inkqubo yokuqhuba ibhulorho: Inkqubo yokuqhuba ibhulorho inenjini, iigiya, kunye namavili okanye iirola ezenza ukuba ikhreyini ikwazi ukuhamba ngobude bebhanti enye. Inika intshukumo ethe tyaba yecrane.
5. Ulawulo: I-crane ilawulwa ngokusebenzisa indawo yokulawula okanye i-pendant control. Olu lawulo luvumela umqhubi ukuba aqhube i-crane, alawule ukunyuswa kunye nokwehliswa kwemithwalo, kwaye ahambise i-crane ecaleni kwendlela yeenqwelo-moya.

UmGaqo wokuSebenza:

Umgaqo-siseko wokusebenza wekhreyini enye yegirder ubandakanya la manyathelo alandelayo:

1. Power On: I-crane ivuliwe, kwaye ulawulo luyasebenza.
2. UkuSebenza kokuPhakamisa: Umsebenzisi usebenzisa ulawulo ukuze avule i-motor ye-hoist, eqala indlela yokuphakamisa. Ikhonkco okanye i-attachment yokuphakamisa iyancipha kwindawo efunwayo, kwaye umthwalo unamathele kuyo.
3. Ukushukuma okuthe tye: Umsebenzisi uvula inkqubo yokuqhuba ibhulorho, evumela i-crane ukuba ihambe ngokuthe tye ecaleni kwebhanti enye ukuya kwindawo efunwayo ngaphezu kwendawo yokusebenza.
4. Intshukumo ethe nkqo: Umsebenzisi usebenzisa izilawuli ukuze avule i-hoist motor, ephakamisa umthwalo ngokuthe nkqo. Umthwalo unokunyuswa okanye ukuhla njengoko kufuneka.
5. Ukuhamba okuthe tye: Wakuba umthwalo unyusiwe, umqhubi unokusebenzisa ulawulo ukuhambisa i-crane ngokuthe tye ecaleni kwebhanti enye ukuya kwindawo oyifunayo yokubeka umthwalo.
6. Ukunciphisa Umsebenzi: Umsebenzisi wenza ukuba i-hoist motor isebenze kwicala lokunciphisa, ngokuthe ngcembe ehlisa umthwalo kwindawo oyifunayo.
7. Ukucinywa kwamandla: Emva kokuba imisebenzi yokuphakamisa kunye nokubeka igqityiwe, i-crane iyacinywa, kwaye ulawulo luyacinywa.

Kubalulekile ukuqaphela ukuba amacandelo athile kunye nemigaqo yokusebenza inokwahluka ngokuxhomekeke kuyilo kunye nomvelisi wecrane enye yegirder overhead.

1. Ubuchule beSithuba: Iikhreyini eziphezu kwebhanti enye ziyaziwa ngoyilo lwazo lokonga indawo. Ngomqadi omnye ojikeleza indawo yokusebenza, zifuna imvume engaphantsi kwe-overhead xa kuthelekiswa ne-double girder cranes, ezenza zilungele izibonelelo ezine-headroom encinci.
2. Ixabiso Elisebenzayo: Iikhreyini zegirder enye zihlala zixabisa ngaphezulu kune-double girder cranes. Uyilo lwazo olulula kunye namacandelo amancinci abangela iindleko eziphantsi zokuvelisa kunye nokufakwa.
3. Ubunzima obuKhaphukhaphu: Ngenxa yokusetyenziswa komqadi omnye, iikhreyini zegirder enye zikhaphukhaphu ngobunzima xa kuthelekiswa ne-double girder cranes. Oku kwenza kube lula ukuzifaka, ukugcina, kunye nokusebenza.
4. Ukuguquguquka: Iikhreyini ezingaphezulu zegirder zinokulungiswa ukuze zihlangabezane neemfuno ezahlukeneyo zokuphakamisa. Zifumaneka kwiimpawu ezahlukeneyo, ukuphakamisa amandla, kunye ne-spans, ezivumela ukuba zilungelelaniswe kwiindawo ezahlukeneyo zokusebenza kunye nobukhulu bomthwalo.
5. Ukuguquguquka: Ezi cranes zibonelela ngokuguquguquka ngokwemiqathango yokuhamba. Bangakwazi ukuhamba ngobude be-single girder, kwaye i-hoist inokunyusa kwaye ihlise imithwalo njengoko kufuneka. Oku kubenza bafanelekele uluhlu olubanzi lwezicelo, ukusuka ekukhanyeni ukuya kwimisebenzi ephakathi yokuphakamisa umsebenzi.
6. ULondolozo olulula: Iikhreyini zegirder enye zinesakhiwo esilula, esenza ukugcinwa kunye nokulungiswa kube lula xa kuthelekiswa ne-double girder cranes. Ukufikelela kumacandelo kunye namanqaku okuhlola kulula ngakumbi, ukunciphisa ixesha lokunciphisa ngexesha lemisebenzi yokulondoloza.
