I-hook ye-crane yebhuloho ingenye yezingxenye eziyisisekelo zemishini yokuphakamisa, esetshenziselwa ukulengiswa nokuthatha izinto ezisindayo. Imvamisa yakhiwa kusuka ku-alley enamandla anamandla futhi inamandla aphezulu ashubile futhi agqoke ukumelana. Ukwakheka kwegwegwe kufaka izingxenye ezintathu: umzimba we-hook, intamo ye-hook kanye nesibambo se-hook. Ezinye izingwegwe zihlome ngedivayisi yokukhiya ukuphepha ukuvikela izinto ezisindayo ekuweni ngengozi. Ngokwezidingo zokusetshenziswa, i-hook ingahlukaniswa ngezinhlobo ezimbili: i-hook eyodwa kanye ne-double hook, efanelekile ekuphakamiseni imisebenzi yama-ahlukene ama-tonnages ahlukene.
Ukuqinisekisa ukuphepha kokusebenza, igwegwe kufanele lihambisane namazinga kazwelonke noma embonini (njenge-GB
t 10051 "Ukuphakamisa Hook"). Ngaphambi kokusebenzisa, hlola ukuthi ingaphezulu le-hook linama-crack, ama-deformation noma ukugqoka okunzima, nokwenza ukutholwa kwephutha njalo. Ukulungiswa kwansuku zonke kufaka phakathi ukugcoba ingxenye ejikelezayo yentambo ye-hook, ukugqwala kokuhlanza kanye nokulahla imfucumfucu, nokugwema ukulayisha ngokweqile. Uma ukuvulwa kwe-hook kutholakala kudlula i-15% yosayizi woqobo noma ukuguquguquka kwe-torsional kudlula i-10 °, kufanele ithathelwe indawo ngokushesha.
Izingwegwe zeBridge Crane zisetshenziswa kabanzi ekuphatheni ngokwezinto ezibonakalayo emafektri, emachwebeni, ezindaweni zokugcina izimpahla nezinye izindawo. Lapho ukhetha imodeli, udinga ukucubungula umthamo wokuphakamisa olinganiselwe, okusebenzayo (okufana ne-M4-M6) kanye nokusebenzisa imvelo (njengezidingo zokulwa nokuphikisana). Ukuze kusetshenziswe kaningi noma ukuphakamisa okusindayo, kunconywa ukusebenzisa izingwegwe ezimbili noma ukufaka ama-pulleys ukusabalalisa amandla. Ngaphezu kwalokho, izimo zokusebenza ezikhethekile (ezinjengokushisa okuphezulu namazinga okushisa aphansi) zidinga ukusetshenziswa kwezingwegwe zezinto ezihambisanayo ukuze kuqinisekiswe ukuphepha nokuqina.
