I-Underhung bridge craneskuyisinqumo esihle sefekthri nezindawo zokugcina izimpahla ezifuna ukukhulula izithiyo zesikhala saphansi futhi andise ukuphepha nokukhiqiza. Ama-cranes angaphansi (ngezinye izikhathi abizwa ngokuthi ama-underslung bridge cranes) awadingi ukusekela amakholomu aphansi. Lokhu kungenxa yokuthi ngokuvamile bagibela ama-flange aphansi emishayo yemigwaqo elenga ophahleni lwesikhungo noma imishayo.
Ngokulungiselela ukufinyelela ekugcineni, ukulengiswaibhuloho ama-cranes asebenzisa kahle indawo yesikhungo. Okusho ukuthi, avumela ama-cranes ukuthi agibele eduze kwamaloli okugcina noma ekugcineni kwe-runway kunama-cranes agijima phezulu. Ukucushwa okungamiswe kancane futhi kukhulisa indlela yokusondela ekugcineni kwebhuloho, noma ibanga lemishayo yebhuloho ukusuka odongeni noma ekugcineni komgwaqo.
UAma-cranes e-nderhung anomthamo olinganiselwe wokuphakamisa ngoba imishayo imisiwe ophahleni lwesakhiwo. Ngaphambi kokukhetha ingaphansislung ibhulohoi-crane, kufanele uhlole amandla esakhiwo sophahla lwesikhungo. Imishayo yokusekela ingangezwa ukwandisa umthamo wokulayisha.
Iphakeme kune-I-Beams ngamandla, ukuqina, nokuvumelana.
Ukuphila kwethrekhi okunwetshiwe uma kuqhathaniswa ne-I-Beam Systems.
Ukwandiswa kwesistimu kulula futhi kuyabiza.
Ama-rails aqondile aphumela ekufakweni okulula, okubikezelwe, nezindleko eziphumelelayo.
Amakhono okuhlanganisa asebenzayo aqeda izakhiwo ezisekelayo ezengeziwe ezibizayo.
Ukumiswa okuguquguqukayo kunikeza impilo ende kanye nesondlo esincane.
Enye inzuzo enkulu yengaphansilengiswa ama-cranes angaphezuluukuguquguquka kwabo ukuhamba endaweni yonke. I-Underhungibhuloho ama-crane ayakwazi ukusondela ekugcineni kwemigwaqo yezindiza namabhuloho, okuhlinzeka indawo eyengeziwe yezinsiza ezingafinyelelwa ngama-cranes angaphansi. I-crane hook iphinde ibe lula ku-opharetha ukuthi ayiqhube ngoba incane futhi inikeza ukuguquguquka okwengeziwe ebhulohweni.
I-SEVENCRANE ingakusiza ukuthi uhlole zonke izinketho ezitholakalayo ze-crane bese ukhetha evumelana kangcono nesicelo sakho nendawo. Bangaphinde bakweluleke ngezinhlelo zokulungisa ukuze ugcine i-crane yakho isebenza kahle kakhulu nokwethembeka.
