Amakhreyini aqalisiwe, eyaziwa nangokuthi ama-crane e-gantry aqalisiwe, angumkhiqizo obalulekile embonini yokwakha kanye nengqalasizinda. Iyi-crane ekhethekile esetshenziswa ekwakhiweni kwamabhuloho, ama-viaducts kanye nezinye izakhiwo eziphakeme. Lolu hlobo lwe-crane lwenzelwe ukuphakamisa nokubeka izingxenye zekhonkrithi ezilungisiwe noma izinsimbi zensimbi endaweni yazo ngesikhathi sokwakha.
Uma ukhetha umkhiqizo we-launch crane, kubalulekile ukusebenza nenkampani ye-launch crane ethembekile nenedumela elihle. Inkampani ethembekile izoba nefektri ye-launch crane esezingeni eliphezulu lapho iklama, ikhiqiza futhi ihlole khona imikhiqizo yayo ukuqinisekisa ukuthi ihlangabezana nezindinganiso zekhwalithi ephezulu kanye nokuphepha. Ngaphezu kwalokho, umhlinzeki we-launch crane othembekile uzohlinzeka ngezinsizakalo zokusekela eziphelele kanye nokugcinwa ukuqinisekisa ukusebenza kahle kanye nokuphila kwenkonzo ye-crane.
Uma ukhetha umkhiqizo we-crane ogibele iloli, kubalulekile ukucabangela izici ezifana nomthamo wokuphakamisa, ubude besikhathi, kanye nezidingo zokwakha zizonke. Inkampani ye-crane yokuqalisa edumile izohlinzeka ngemikhiqizo eyahlukahlukene ukuze ivumelane nezidingo ezahlukahlukene zephrojekthi, iqinisekise ukuthi i-crane efanele ikhethiwe kuphrojekthi ethile yokwakha.
Ukuqala i-gantry crane kubalulekile ekwakhiweni okuphumelelayo nokuphephile kwezakhiwo eziphakeme. Zinikeza amakhono okubeka nokuphakamisa anembile, okwenza kube yinto ebalulekile embonini yokwakha. Ngokusebenzisana nezinkampani ezidumile ze-jib crane kanye nabaphakeli, izinkampani zokwakha zingaqinisekisa ukuthi zithola imikhiqizo ye-jib crane esezingeni eliphezulu, ethembekile, nephumelelayo yamaphrojekthi azo.
Ngamafuphi, ama-launch cranes noma ama-launch gantry cranes ayimikhiqizo ebalulekile embonini yokwakha. Lapho ukhetha imikhiqizo ye-launch crane, kubalulekile ukusebenza nezinkampani ezidumile ze-launch crane kanye nabaphakeli ukuqinisekisa ikhwalithi ephezulu kanye nokuthembeka. Ngemikhiqizo ye-launch crane efanele, izinkampani zokwakha zingandisa ukusebenza kahle kanye nokuphepha kokwakhiwa kwesakhiwo esiphakeme.
