Te whakaurunga o te wiri toka ringaringa

I whakaurua mai te wiri toka ringaringa e Ingersoll-RandCo. i te tau 1912. E ai ki te āhua o te mana, ka wehea kia whā ngā wāhanga: te hauhautanga, te waipēhi, te hiko me te puku mura o roto. Ko te hauhautanga ngā mea e whakamahia whānuitia ana. He pai ngā wiri toka ringaringa mō te keri i ngā poka pupuhi ki raro, ki raro rānei, ngā poka pupuhi tuarua nui, ngā poka pūtu (ngā poka poutū papaku), me ngā poka porotaka pumau (ngā poka whakapae papaku) i roto i te konganuku pakeke-waenga me te konganuku pakeke-waenga. Ko te whānui o te wiri he 19~42mm, ā, ko te hohonutanga mōrahi o te poka he 5m, he iti iho i te 2.5m te nuinga o te wā. Ko te kaha pānga o ngā wiri toka ringaringa hau e whakamahia whānuitia ana ko te 15~45J, ko te auau pānga ko te 27~36Hz, ko te taipana wiri ko te 8~13N·m, ko te pēhanga mahi ko te 0.5~0.7MPa, ko te hau e pau ana ko te 1500~3900L/min, ā, ko te taumaha ko te 7~30kg.
