Mu isi y’imashini ziremereye, akamaro k’ibice byizewe kandi biramba ntikagombye kurenza urugero. Muri ibyo,inzira zo gukurura umupira, izwi kandi nka 'rubber digger tracks', igira uruhare runini mu kongera imikorere n'ubushobozi bw'ibikoresho bitandukanye by'ubwubatsi n'ubuhinzi. Uko inganda zikomeza gutera imbere, icyifuzo cy'inzira nziza zo gukurura rubber cyariyongereye, bituma hakenerwa uburyo bwo gupakira no kohereza ibicuruzwa neza kugira ngo hahuzwe n'ibyo isoko rikeneye.

Inzira zo gucukura imipira zigenewe gutanga imbaraga n'ubudahangarwa ku butaka butandukanye, bigatuma ziba nziza ku bacukura, amamashini atwara imizigo, n'izindi mashini ziremereye. Imiterere yazo ya mipira ntigabanya gusa kwangirika k'ubutaka ahubwo inagabanya urusaku n'ihindagurika ry'imitingito, bigatuma ziba amahitamo meza mu mishinga y'ubwubatsi bw'imijyi. Ariko, inyungu z'izi nzira ntizirenze imikorere yazo; uburyo bwo gutwara imizigo no kohereza imipira ni ingenzi cyane kugira ngo igere aho igeze imeze neza.

Ku bijyanye no gupakirainzira zo gucukura za kabutura, gukora neza ni ingenzi. Uburyo bwiza bwo gufata bugomba gukoreshwa kugira ngo hirindwe kwangirika kose mu gihe cyo gupakira. Ibi birimo gukoresha ibikoresho byabugenewe mu guterura no gushyira inzira mu buryo buhamye ku binyabiziga bitwara abantu. Byongeye kandi, kugenzura ko inzira zifunze neza mu gihe cyo kuzitwara ni ingenzi kugira ngo hirindwe ko zihinduka, bishobora gutuma zisharira.

Uburyo bwo kohereza imizigo ya kabutura bisaba igenamigambi no gushyira mu bikorwa neza. Ibigo bigomba gusuzuma ibintu nk'uburemere, ingano, n'aho bijya kugira ngo bihitemo uburyo bwiza bwo kohereza. Haba ku butaka, mu mazi, cyangwa mu kirere, intego ni ugutanga ibi bintu by'ingenzi vuba kandi mu mutekano ku bwubatsi cyangwa ku bacuruzi b'ibikoresho.

Mu gusoza, gupakira no kohereza inzira zo gupakira za kabutura ni bimwe mu bintu by'ingenzi mu ruhererekane rw'ibikoresho mu nganda zikora imashini zikomeye. Mu gushyira imbere imikorere myiza n'ubwitonzi muri izi nzira, ibigo bishobora kwemeza koinzira zo gucukura umupirabageze biteguye gukora, amaherezo bakagira uruhare mu iterambere ry'imishinga y'ubwubatsi n'ubuhinzi ku isi hose.
