Kuphatikiza apo, milu ikuluikulu ndi yakuya ndiyofunika kutsidya la nyanja ndi kutsidya lina la mtsinje. Chifukwa chake, molingana ndi zifukwa ziwiri zomwe tafotokozazi, tidafufuza ndikupanga makina obowola ozungulira a TR460 omwe ali ndi ubwino wokhazikika kwambiri, mulu wawukulu ndi wakuya komanso wosavuta kuyenda.
Kapangidwe ka chithandizo cha Triangle kumachepetsa kutembenuka kozungulira ndikuwonjezera kukhazikika kwa makina obowola mozungulira.
Winch yayikulu yokwera kumbuyo imagwiritsa ntchito ma motors awiri, zochepetsera pawiri komanso kapangidwe ka ng'oma imodzi yomwe imapewa kupota kwa zingwe.
Dongosolo la Winch la anthu limatengedwa, sitiroko ndi 9m. Mphamvu zonse za unyinji & sitiroko ndizokulirapo kuposa za silinda, zomwe ndizosavuta kuyika kasupe Wokometsedwa ndi ma hydraulic ndi magetsi owongolera amawongolera kulondola kwadongosolo komanso kuthamanga kwazomwe zimachitika.
