Imashini zitera ivyuma zikonje-ziringaniye zatanguye gutegurwa kandi zikorwa mu myaka ya 1920; gushika muri iki gihe, vyarateye imbere mu kiringo c’imyaka hafi ijana. Mu bihe vya none, ubuhinga bwavyo bwarakuze cane kandi burahuye, kandi ubu burakoreshwa cane kw’isi yose. Naho izo mashini zishobora gukora ivyuma bifise ubushobozi bwo gushonga cane-nk’ivyuma vy’umuringa-abaguzi bategerezwa guhitamwo ibipimo vy’ubushobozi vyihariye bishingiye ku bisabwa mu guhingura ibihimba vy’ivyuma -bitegekanijwe. Mu yandi majambo, ubushobozi bwose bw’ico gikoresho, ukuntu gikora neza, ubushobozi gitanga, n’ibindi biranga bitegerezwa kwubahiriza cane ingingo mfatirwako z’ubuhinga n’ibisobanuro bibereye.
Uyu musi, turaza kudondora ingingo ngenderwako zitari nke zo guhitamwo ivyo bikoresho.
1. Gutahura neza ubwoko butandukanye n’ibiranga ibikoresho biriho.
2. Rimbura ubwoko bwihariye bw’ivyuma bizokoreshwa mu gukora ibice vy’ivyuma-vyaba ari ivyuma bitagira ibara, ivyuma vy’aluminium, canke ikindi kintu.
3. Ivyo bikoresho vyatowe bitegerezwa kuba bishobora gushitsa ibisabwa mu vy’ubuhinga no mu bijanye n’ibikorwa vy’ibihimba vy’ivyuma vy’ivyuma.
.
5. Nk’itegeko ry’ishimikiro, bitegerezwa kwitwararika bimwe bishitse ukwizigirwa kw’ibikoresho, ibiranga umutekano, n’igiciro muri rusangi-bikora neza.
6. Iyo umukiriya akora ibihimba bitandukanye vy’ivyuma vy’ivyuma, yamara umubare w’ivyuma akora ku bwoko bumwe bumwe ari muto cane, akwiye-mu gihe agishitsa ibisabwa mu ngingo ya 4-guhitamwo neza imashini ifise ibisobanuro bihuye. Intumbero ni uguhitamwo imashini imwe ishobora gukora ivyo bihimba vyinshi bikenewe, gutyo bikagabanya amahera yo kuronka ibikoresho.
7. Mu bipimo bitandukanye vy’ubushobozi n’ibimenyetso vy’ubuhinga vy’ibikoresho, imbere y’ibindi ni ubushobozi bw’imashini bwo gutera inshinge. Igihe ugereranya imashini zifise ubunini bumwe canke busa, ni vyiza guhitamwo ikigereranyo gitanga urutonde rwagutse rw’ibikorwa ku bijanye n’imirongo yayo y’urushinge.
Ivyo bisozera intangamarara yacu ku ngingo nyamukuru zo guhitamwo amashini y’ugutera ivyumba vy’ubukonje-biringaniye. Kubera ko uburyo ibikoresho bigurwa bugira ico bukoze ata guca ku ruhande ku bijanye n’ingene bikoreshwa, abakiriya bategerezwa kugira umwete mwinshi no kwitwararika igihe bahitamwo.
