Iikhreyini ze-Tower zifika kwindawo yolwakhiwo kwi-10 ukuya kwi-12 iirigi zeetrekta ezirhuqwayo.Abasebenzi basebenzisa i-crane ehambayo ukudibanisa ijib kunye necandelo loomatshini, kwaye babeke la malungu axwesileyo kwi-40-foot (12-m) yemasti enamacandelo amabini emasti.I-crane ehambayo ngoko yongeza i-counterweights.
Imasti iphakama kwesi siseko siqinileyo.Imasti sisakhiwo esikhulu, esingunxantathu welathisi, ngokuqhelekileyo 10 iinyawo (3.2 yeemitha) square.Ulwakhiwo olunxantathu lunika imasti amandla okuhlala nkqo.
Ukunyuka kowona bude buphezulu, ikhreyini izikhulisela icandelo lemasti enye ngexesha!Abasebenzi basebenzisa indawo yokukhwela ephezulu okanye isakhelo sokukhwela esilingana phakathi kweyunithi yokuxhela kunye nomphezulu wemasti.Nantsi inkqubo:
Abasebenzi baxhoma ubunzima kwijib ukulinganisa ubunzima bokumelana.
Abasebenzi babamba iyunithi yokubulala ukusuka phezulu kwemasti.Iinkunzi ze hydraulic ezinkulu kumphezulu onyukayo zityhala iyunithi yokuxhela iphakame kangange 20m (6 m).
Umsebenzisi we-crane usebenzisa i-crane ukuphakamisa elinye icandelo le-mast ye-20-foot kwisithuba esivulwe yifreyimu yokunyuka.Xa sele ibotshiwe endaweni, ikhreyini inobude obuziimitha ezingama-20!
Sakuba sigqityiwe isakhiwo kwaye ilixesha lokuba icrane yehle, inkqubo iyatshintshwa - ikhreyini iqhawuka imasti yayo kwaye iikhreyini ezincinci ziqhaqhe ezinye.
