Lapho ukhetha umkhiqizo wokwethulwa kwe-crane, kubalulekile ukusebenzisana nenkampani ethembekile nenedumela lokwethula i-crane.Inkampani ehlonishwayo izoba nefekthri yesimanje yokwethulwa kwe-crane lapho iklama, ikhiqiza futhi ihlola imikhiqizo yayo ukuze iqinisekise ukuthi ihlangabezana nezindinganiso eziphakeme kakhulu nezokuphepha.Ukwengeza, umphakeli onokwethenjelwa wokwethulwa kwe-crane uzohlinzeka ngezinsizakalo eziphelele zokusekela nokunakekela ukuze kuqinisekiswe ukusebenza kahle nempilo yesevisi ye-crane.
Uma ukhetha umkhiqizo we-crane ogibele ngeloli, kubalulekile ukucabangela izinto ezifana nomthamo wokuphakamisa, ubude besikhathi, kanye nezimfuneko zokwakha sezizonke.Inkampani ehlonishwayo yokwethulwa kwe-crane izohlinzeka ngemikhiqizo eminingi ukuze ihambisane nezidingo zephrojekthi ehlukahlukene, iqinisekisa ukuthi kukhethwe u-crane ofanele wephrojekthi ethile yokwakha.
Ukuqala i-gantry crane kubalulekile ekwakhiweni okuphumelelayo nokuphephile kwezakhiwo eziphakeme.Bahlinzeka ngamakhono anembile okubeka kanye nokuphakamisa, okubenza babaluleke kakhulu embonini yezokwakha.Ngokusebenzisana nezinkampani ezihlonishwayo ze-jib crane nabahlinzeki, izinkampani zokwakha zingaqinisekisa ukuthi zithola imikhiqizo ye-jib crane yekhwalithi ephezulu, ethembekile, nesebenzayo yamaphrojekthi azo.
Kafushane, ama-cranes okuqalisa noma ukuqalisa ama-gantry cranes yimikhiqizo ebalulekile embonini yezokwakha.Uma ukhetha ukwethulwa kwemikhiqizo ye-crane, kubalulekile ukusebenzisana nezinkampani ezihlonishwayo zokwethulwa kwe-crane nabahlinzeki ukuze uqinisekise ikhwalithi ephezulu kakhulu nokuthembeka.Ngemikhiqizo ye-crane yokuqalisa efanele, izinkampani zokwakha zingandisa ukusebenza kahle nokuphepha kokwakhiwa kwesakhiwo esiphakeme.
