Okhreyini be-Tower bafika endaweni yokwakha ngama-trailer ama-trailer angu-10 kuya kwangu-12.Izisebenzi zisebenzisa u-crane ohambayo ukuhlanganisa i-jib nengxenye yemishini, futhi babeke la malungu avundlile ku-40-foot (12-m) mast ehlanganisa izingxenye ezimbili zensika.I-crane ehambayo ibe isingeza ama-counterweights.
Insika ikhuphuka kulesi sisekelo esiqinile.I-mast iyisakhiwo esikhulu, esingunxantathu se-lattice, ngokuvamile esingamafidi angu-10 (3.2 amamitha) isikwele.Isakhiwo esimanxantathu sinikeza insika amandla okuhlala iqondile.
Ukuze ikhuphuke ifinyelele ekuphakameni kwayo okuphezulu, i-crane izikhulisela ingxenye yensika eyodwa ngesikhathi!Iqembu lisebenzisa umqwali ongaphezulu noma ifreyimu yokugibela elingana phakathi kweyunithi yokuhlinza nangaphezulu kwensika.Nansi inqubo:
Abasebenzi balengisa isisindo ku-jib ukuze balinganisele i-counterweight.
Iqembu lisusa iyunithi yokubulala kusukela phezulu kwensika.Izinqama ezinkulu ezisebenza nge-hydraulic endaweni yokugibela phezulu ziphusha iyunithi yokubulala ikhuphuke ngamafidi angu-20 (6 m).
Umsebenzisi we-crane usebenzisa i-crane ukuphakamisa esinye isigaba sensika esingamamitha angu-20 esikhaleni esivulwe wuhlaka lokugibela.Uma usuboshiwe endaweni, i-crane iba ngamafidi angu-20 ubude!
Uma isakhiwo sesiqediwe futhi sekuyisikhathi sokuthi u-crane wehle, inqubo iyahlehliswa - u-crane uqaqa insika yawo bese ama-crane amancane eqaqa amanye.
