Ama-cranes agijima phezulu ahamba kabili angase ahlinzekwe ku-Class A, B, C, D, kanye no-E we-CMAA, anamandla avamile amathani angu-500 futhi anwebe amafidi angafika kwangu-200 noma ngaphezulu. Uma iklanywe ngendlela efanele, i-double beam bridge crane ingaba yisixazululo esikahle kumabhizinisi adinga okhreni abasindayo kuya kokuphakathi nendawo, noma izinsiza ezinekhanda elilinganiselwe kanye/noma indawo yaphansi. Idizayini yemishayo ekabili ingaba yinketho engabizi kakhulu kukhreni we-heavy duty endaweni yokukhiqiza, egcina impahla, noma endaweni yokuhlanganisa. I-crane edinga amandla aphezulu, ukunwetshwa okubanzi, noma ukuphakama okuphezulu kungazuza edizayini enegida eliphindwe kabili, kodwa ingabiza kakhulu kusengaphambili.
I-double beam bridge crane ivamise ukudinga imvume ephezulu ngaphezu kokuphakama kweleveli ye-cranes, njengoba amaloli okuphakamisa enqamula ngaphezu kwamagida kudekhi ye-cranes. Amabhuloho amabhuloho ahamba phezu kwamathrekhi e-crane abekwe phezu komgwaqo we-crane. Amaloli okugcina - Ukusekela ibhuloho lebhuloho kulivumela ukuthi ligibele ojantshi be-crane, okuvumela i-crane ukuthi ihambe yehla yenyuka ku-crane runway. I-Bridge Girder - Amagida avundlile ku-crane asekela i-cable trolley kanye nokuphakamisa.
Isakhiwo esiyisisekelo se-crane yebhuloho le-double beam, amaloli agijima kumathrekhi anwebeka ngobude besistimu yethrekhi, kanye ne-bridge-carriage-girder egxilwe emalolini asekupheleni, lapho i-trolley ye-lifti imisa i-lift futhi ihambe phezu kwayo. ibhuloho. Okhrayini bebhuloho abaginqika kabili bakhiwe ngamapulangwe amabili ebhuloho anamathiselwe kumzila wezindiza, ngokuvamile ahlinzekwa ngezixhumi zezintambo ezisebenza ngogesi ngaphezulu kwaphezulu, kodwa angase ahlinzekwe ngamaketango aphezu kwekhanda asebenza ngogesi ngokuya ngohlelo lokusebenza. I-SEVENCRANE Overhead Cranes kanye nama-Hoists anganikeza ama-cranes amabhuloho e-single girder ukuze asetshenziswe ngokujwayelekile, futhi anikeze ama-cranes amabhuloho amabhuloho akhiwe ngokwezifiso ezimboni ezihlukahlukene. Ngenxa yokuthi ama-swivels angahlala phakathi noma ngaphezulu kwemishayo enqamulayo, ukuphakama okwengeziwe okungu-18-36 okujikayo kuyatholakala uma kusetshenziswa i-double beam bridge crane.
