Indobo y'inkoko, inkongoro n'ingagi bigabanijwemo ubwoko bubiri: indobo zigabanijwe hamwe n'indobo zifatanije, buri kimwe gifite imiterere ine.Ibikoresho bikozwe mubikoresho fatizo bya HDPE, ntibyoroshye kwangizwa no gusohora, kandi birwanya gukandagira no kwikanyiza mugihe cyo kugaburira.Igishushanyo mbonera hamwe nigishushanyo mbonera cyo kwirinda imyanda.Umubiri wose ufite ubukana bwiza, ntabwo byoroshye guhindurwa no gukuramo, kandi birashobora no gukoreshwa muburyo bwo guhindura ibintu.Hasi ihujwe nindobo, naho ingunguru ihujwe na chassis, irakomeye kandi ntibyoroshye kurekura.
