Kurinda ecran ni gahunda yumutekano mukubaka inyubako ndende. Sisitemu igizwe na gari ya moshi hamwe na sisitemu yo guterura hydraulic kandi irashobora kuzamuka yonyine idafite crane. Mugukingira ecran ifite ahantu hose hasukwa hafunzwe, itwikiriye amagorofa atatu icyarimwe, irashobora kwirinda neza impanuka nyinshi zo mu kirere no kurinda umutekano wubwubatsi. Sisitemu irashobora kuba ifite ibikoresho byo gupakurura. Ihuriro ryo gupakurura ryorohereza kwimura impapuro nibindi bikoresho mu igorofa yo hejuru nta gusenya.Nyuma yo gusuka icyapa, urupapuro rwabigenewe hamwe na scafolding birashobora kujyanwa kumurongo wo gupakurura, hanyuma bikazamurwa na crane umunara kugeza murwego rwo hejuru kugirango ukore intambwe ikurikira, bityo ko ikiza cyane abakozi nubutunzi kandi ikanoza umuvuduko wubwubatsi.
Sisitemu ifite hydraulic sisitemu nkimbaraga zayo, kuburyo ishobora kuzamuka yonyine. Crane ntabwo ikenewe mugihe cyo kuzamuka. Umwanya wo gupakurura uroroshye kwimura impapuro nibindi bikoresho muri etage yo hejuru nta gusenya.
Mugukingira ecran nuburyo bugezweho, bugezweho bujyanye nibisabwa byumutekano numuco kurubuga, kandi rwose byarakoreshejwe cyane mukubaka umunara muremure.
Byongeye kandi, isahani yimbere yintwaro yo kurinda ni ikibaho cyiza cyo kwamamaza kugirango bamenyekanishe rwiyemezamirimo.
