Ubunzima bokuzimela obulula, umthwalo omncinci wevili, ukukhutshwa kakuhle. Umthwalo wevili elincinane kunye nokucocwa kakuhle kunokunciphisa utyalo-mali kwisakhiwo somzi-mveliso.
Ukusebenza okuthembekileyo, ukusebenza okulula, kunye nokusetyenziswa okuncinci. Le crane inokusebenza okuthembekileyo kunye nokuqina, okunciphisa iindleko zokugcina; Umsebenzi olula wehlisa ubunzulu bomsebenzi; Ukusetyenziswa kwamandla amancinci kuthetha ukonga iindleko zokusetyenziswa.
Ngokuqhelekileyo lolona khetho lubiza kakhulu kwiikhreyini ezikhanyayo ukuya eziphakathi, zombini ngokwexabiso lomatshini kunye nokugcinwa okulandelayo.
Iikhreyini eziphezu kwentloko ezimbini zinomthamo omkhulu wokuthwala umthwalo kunye nokuzinza, kwaye zifanelekile ukuphakamisa iifektri ezinkulu kunye neempahla ezinkulu, ezifana nezityalo ezinkulu zokulungisa oomatshini, iindawo zokugcina iimpahla kunye nezinye iindawo apho izinto ezinzima zifuna ukuphakanyiswa kwiindawo eziphakamileyo.
Iikrane zebhulorho eziphindwe kabini zihlala zixhotyiswe ngeenkqubo zokulawula eziphambili kunye nezixhobo zokhuseleko, ezifana neenkqubo zokulwa nokungqubana, imida yomthwalo, njl., Ukuqinisekisa ukhuseleko kunye nokuchaneka kwenkqubo yokusebenza.
Imveliso enzima: Kwimizi-mveliso yoomatshini abanzima, iikhreyini eziphezu kwentloko ezimbini zisetyenziselwa ukudibanisa kunye nokuhambisa iindawo ezinkulu zoomatshini. Ngenxa yomthamo wayo ophezulu womthwalo kunye nesithuba esikhulu, iindawo ezinzima zinokuphakanyiswa ngokulula kwaye zibekwe ngokuchanekileyo.
Imveliso yensimbi: Ishishini lensimbi lifuna ukuhambisa inani elikhulu lezinto eziluhlaza kunye neemveliso ezigqityiweyo. Iyakwazi ukusingatha ubushushu obuphezulu, izixhobo eziphezulu kunye nokusebenza ngokuzinzile kwiindawo eziphezulu zokushisa.
Ukuphathwa kwempahla: Kwiindawo zokugcina iimpahla ezinkulu kunye namaziko othutho, isetyenziselwa ukuhambisa kunye nokuhlela iimpahla ezahlukeneyo, ngakumbi kwiindawo ezifuna i-spans ezinkulu kunye nemithwalo ephezulu.
Umgca wokudityaniswa kwemoto: Kwimizi-mveliso yokuvelisa iimoto, isetyenziselwa ukuhambisa iindawo zemoto ukuze zidityaniswe kwaye zihlolwe. Umthamo wayo osebenzayo wokuphatha kunye nomsebenzi ochanekileyo wokumisa unokuhlangabezana neemfuno zomgca wokuvelisa.
Ukugcinwa kwezixhobo zokuvelisa umbane: Kwimizi-mveliso yombane, iikhreyini ze-double girder overhead zisetyenziselwa ukugcina nokutshintsha izixhobo zokuvelisa umbane ezifana neebhoyila, iijenereyitha, njalo njalo.
Ukulungiswa kweenqanawa: Ngexesha lokulungiswa kweenqanawa, ii-cranes ze-double girder overhead ziyakwazi ukuhambisa izixhobo ezinzima zokulungisa kunye neendawo ezisecaleni, ukuxhasa inkqubela phambili egudileyo yokusebenza kokulungisa.
Ukuphatha Impahla Yokwakha: Kwiiprojekthi ezinkulu zokwakha, isetyenziselwa ukuhambisa izinto zokwakha nezixhobo, ngakumbi kwiindawo zokwakha apho kufuneka kugutyungelwe iindawo ezinkulu.
Ukhetho loyilo lwengaphezuluinkqubo yecrane yenye yezona zinto zinkulu kububunzima benkqubo kunye neendleko. Ke ngoko, kubalulekile ukuqwalasela ngononophelo ukuba loluphi ulungelelwaniso olufanelekileyo kwisicelo sakho. Ibhanti kabiningaphezuluiicranes zineebhulorho ezimbini endaweni yenye. Njengeecranes zegirder enye, kukho imiqadi yokuphela kumacala omabini ebhulorho. Ekubeni i-hoist inokuthi ibekwe phakathi kweeplanga okanye ngaphezulu kweeplanga, unokufumana i-18 "- 36" eyongezelelweyo yokuphakama kwe-hook ngolu hlobo lwe-crane. Ngoxa i-double girderngaphezuluiicranes zinokuba zibaleka phezulu okanye ziqhube phantsi, uyilo olusebenzayo oluphezulu luya kubonelela ngobude obuphezulu be hook.
