Ubusanzwe umunara wa crane ufite ibisobanuro bikurikira:
Uburebure ntarengwa budashyigikiwe - metero 265 (metero 80) Crane irashobora kugira uburebure bwuzuye burenze metero 265 iyo ihambiriwe ninyubako nkuko inyubako izamuka ikikije crane.
Ikigereranyo ntarengwa - metero 230 (metero 70)
Imbaraga ntarengwa zo guterura - toni 19.8 (toni 18 metric), toni 300-metero (metric ton = tonne)
Kurwanya ibiro - toni 20 (toni 16.3 metric)
Umutwaro ntarengwa crane ishobora guterura ni toni 18 metric (39,690 pound), ariko crane ntishobora guterura ubwo buremere iyo umutwaro uhagaze kumpera ya jib.Iyo umutwaro wegereye kuri mast, niko uburemere bwa kane bushobora guterura neza.Urutonde rwa toni 300 rukubwira isano.Kurugero, niba uyikoresha ashyira umutwaro metero 30 (metero 100) uvuye kuri mast, crane irashobora guterura toni 10.1.
Crane ikoresha uburyo bubiri bwo guhinduranya kugirango umenye neza ko uyikoresha atarenza urugero:
Impinduka ntarengwa yimitwaro ikurikirana gukurura umugozi kandi urebe neza ko umutwaro utarenze toni 18.
Umwanya wo kwipakurura uremeza neza ko uwukora atarenza toni-metero ya crane nkuko umutwaro wimuka kuri jib.Iteraniro ry'umutwe w'injangwe mu gice cyo guswera rirashobora gupima urugero rwo gusenyuka muri jib no kumva iyo ibintu birenze urugero.
Noneho, byaba ari ikibazo kinini rwose niba kimwe muribi bintu cyaguye kurubuga rwakazi.Reka tumenye icyatuma izo nyubako nini zihagarara neza.
