Le khasiUkugijima okuphezuluginda kabiliBridge craneliqukethe ifreyimu ye-beam eyinhloko, idivaysi egijimayo ye-trolley, kanye ne-trolley ephethe idivaysi ephakamisayo nehambayo. Ugongolo oluphambili luvinjelwe ngamathrekhi we-trolley ukuhambisa. Imishayo emibili eyinhloko ifakwe ipulatifomu ephathekayo ngaphandle, uhlangothi olulodwa lusetshenziselwa ukuhlanganisa nokulungisa idivaysi ehamba nge-trolley, futhi ngakolunye uhlangothi kusetshenziselwa ukuhlomisa idivaysi yokusebenza kweTrolley.
Ikhabethe eliphelele eligcwele limisiwe ngaphansi kogongolo oluphambili, kanye nekhonsoli yokuxhumana yokuxhumana noma ibhokisi lokulawula lomshini owodwa lifakiwe kwikhabethe. Isitebhisi sangemuva sifakiwe phakathi kwe-cab kanye neplatifomu yeselula. Ugongolo oluphambiliyeUkugijima okuphezuluginda kabiliBridge crane ixhunyiwe emishameni yokugcina nhlangothi zombili phakathi nendawo njengendawo yokuxhuma.
Enye yezinzuzo eziphambili zeUkugijima okuphezuluibhuloho amakhonsathaNgabe bangenzelwe ukubhekana nemithwalo eyeqisayo. Njengoba kunje, zivame kakhulu ukwedlula ama-cranes aphezulu we-jib, ngakho-ke akugcini nje kuphela ukuthi bangaba namakhono aphezulu alinganiselwe kunama-cranes aphezulu we-cantilever, kodwa futhi bangakwazi ukuhlalisa ama-spans aphezulu phakathi kwamalungu aphezulu abhekene nosayizi omkhulu wesakhiwo esenza uhlelo.
Ukubeka i-20Ibhuloho eliphakeme eliphakeme uhlobo lwenyoni enkuluI-Trolley ngaphezulu kweBridge Gerer futhi ihlinzeka ngezinzuzo ngokubona kwesondlo, okuvumela ukufinyelela okulula nokulungiswa. Uma i-cantilever pendead crane idinga isondlo, kungenzeka ukuthi i-crane trolley kuzodingeka isuswe ebhulini le-girder ukuze likufinyelele kahle.
Noma kunjalo, ukugijima okuphezuluibhuloho I-Crane itholakala ngaphezulu kwe-girder yebhuloho, ngakho-ke abasebenzi bezokulondolozwa bangenza imisebenzi edingekayo esizeni isikhathi eside lapho kukhona indlela yokuhamba noma enye indlela yokufinyelela isikhala.
Le khasi20I-crane ephezulu yebhulohoFuthi lunganikeza ngezinzuzo ezibalulekile ezindaweni lapho isikhala esiphezulu silinganiselwe khona. Lapho uklama uhlelo lwe-crane ebheke ngaphezulu, esinye sezinto ezibaluleke kakhulu okufanele uzigcine engqondweni ukuphakama okuphezulu kwe-hook okudingekayo, okungukuphakama kwesibopho esimweni sayo esiphakeme kakhulu.
