Iikrane zebhokisi zebhokisi ziye zaba yinto ebalulekileyo kulwakhiwo lwentsimbi lwangoku. Zenzelwe ukuphakamisa nokuhambisa imithwalo emikhulu enzima malunga nendawo yokwakha, ukubonelela ngesisombululo esithembekileyo nesisebenzayo sokuphatha izinto eziphathekayo.
Enye yeenzuzo ezinkulu zeekrane zebhokisi kukukwazi ukuhambisa imithwalo ngendlela elawulwayo nechanekileyo. Oku kuluncedo ngakumbi xa kusetyenzwa kwiiprojekthi ezinkulu zeziseko ezingundoqo apho ukhuseleko lubaluleke kakhulu. Abaqhubi becrane banokulawula ngokulula iintshukumo zecrane, baqinisekise ukuba imithwalo iyanyuswa kwaye ithuthwa ngokukhuselekileyo kunye nomngcipheko omncinci weengozi.
Iikhreyini ze-Box girder nazo zomelele ngokumangalisayo kwaye zakhelwe ukumelana neemeko ezirhabaxa zangaphandle zesiza sokwakha. Zenziwe kwizinto ezinamandla, ezinobunzima obunzima, obunika ubomi obude. Oku kuthetha ukuba zinokusetyenziswa ixesha nexesha kwiindawo zokwakha iminyaka emininzi ezayo.
Enye inzuzo yeekrane zebhokisi kukuguquguquka kwazo. Zifanelekele ukuphakamisa izicelo ezahlukeneyo, ukusuka kwiipaneli zekhonkrithi ezihamba phambili ukuya kwiintsimbi zetsimbi kunye nezinye izinto ezisetyenziselwa ukwakhiwa kwesakhiwo sensimbi. Ziyakwazi ukucwangciswa ukuba zihambelane neemfuno ezithile zeprojekthi, ziqinisekisa ukuba i-crane ifanelekile ngenjongo kwaye iyakwazi ukusingatha imithwalo efunekayo.
Ngaphezu koko, ii-cranes zebhokisi zebhokisi ziyaziwa ngesantya kunye nokusebenza kakuhle ekufumaneni izinto zokwakha kwindawo ezifuna ukuya kuyo. Bangakwazi ukuthutha imithwalo enzima ngokukhawuleza kwaye ngokukhuselekileyo ukusuka kwelinye icala lendawo yokwakha ukuya kwelinye, elinokugcina ixesha kunye nemali yeprojekthi. Oku kubaluleke kakhulu kwiiprojekthi zolwakhiwo olukhulu, apho ulibaziseko lunokuba neziphumo ezibi kuhlahlo lwabiwo-mali lweprojekthi nakwixesha elibekiweyo.
Ukuqukumbela, iikrane zebhokisi zisisixhobo esiyimfuneko kwiiprojekthi zokwakha intsimbi. Ukuchaneka kwazo, ukomelela, ukuguquguquka, kunye nokusebenza kakuhle kwazo kuzenza zilungele ukusingatha imithwalo enzima kwiindawo zokwakha. Oku kubangela iimeko zokusebenza ezikhuselekileyo, amaxesha okutshintsha ngokukhawuleza, kunye neprojekthi yokwakha eyonga imali xa iyonke.
