Iikhreyini zokubaleka eziphindwe kabini zodidi oluphezulu zinokubonelelwa kwiKlasi A, B, C, D, kunye ne-E ye-CMAA, enesakhono esiqhelekileyo seetoni ezingama-500 kunye nobubanzi ukuya kuthi ga kwienyawo ezingama-200 okanye ngaphezulu. Xa iyilwe ngokuchanekileyo, i-crane yebhulorho ephindwe kabini inokuba sisisombululo esifanelekileyo kumashishini adinga iikhreyini ezinzima ukuya kwephakathi, okanye izibonelelo ezinentloko enyiniweyo kunye / okanye indawo yomgangatho. Uyilo oluphindwe kabini lwebhamu lunokuba lukhetho olungabizi kakhulu kwi-crane enzima kwimveliso, kwindawo yokugcina impahla, okanye kwindawo yokuhlanganisa. I-crane efuna amandla aphezulu, ububanzi obubanzi, okanye ukuphakama okuphezulu kunokuxhamla kuyilo oluphindwe kabini, kodwa inokubiza ngaphezulu.
I-crane yebhulorho ephindwe kabini idla ngokufuna indawo engaphezulu yokucocwa ngaphezulu kweekhreyini zomphakamo womgangatho wokuphakama, njengoko iilori zokuphakamisa zinqumla ngaphezulu kweebhanti ezikwidekhi yecranes. Iibhanti zebhulorho zihamba ngaphezulu kweengoma zekhreyini ezibekwe phezu komgaqo weenqwelomoya wekhreyini. Iilori zokuphela - Ukuxhasa i-bridge girder ivumela ukuba ikhwele iileyili ze-crane, ezivumela ukuba i-crane ihambe inyuka kwaye ihle kwi-runway ye-crane. I-Bridge Girder - Iibhanti ezinqamlekileyo kwi-crane exhasa i-trolley yekhebula kunye nokuphakamisa.
Ulwakhiwo olusisiseko lwe-crane yebhulorho ephindwe kabini, iilori ezibaleka kwimizila eyandisa kubude benkqubo yengoma, kunye nebhulorho-inqwelo-ehambayo egxininiswe kwiilori ezisekupheleni, apho itroli yokunyusa imisa ukunyuswa kwaye ihambe ngaphaya. ibhulorho. Iikhreyini zebhulorho eziphindwe kabini zenziwe ngemiqadi emibini yebhulorho encanyathiselwe kumgaqo weenqwelo-moya, ebonelelwe ngokuqhelekileyo ngeentambo zokuxhoma ngeentambo zombane ezisebenza ngombane, kodwa zinokubonelelwa ngezixhasi zamatsheyini ombane osebenza ngaphezulu phezulu ngokuxhomekeke kwisicelo. I-SEVENCRANE i-Overhead Cranes kunye ne-Hoists inokubonelela ngee-cranes zebhulorho ezilula ezisetyenziselwa ukusetyenziswa ngokubanzi, kwaye zibonelela ngeekhreyini zebhulorho eziphindwe kabini zamashishini ahlukeneyo. Ngenxa yokuba ii-swivels zinokuhlala phakathi okanye ngaphezulu kweepali ezinqumlayo, i-18-36 eyongezelelweyo yokuphakama kwe-swivel iyafumaneka xa usebenzisa i-crane yebhulorho ephindwe kabini.
