Kua whirihorahia tēnei miihini me te puku wira rere o muri mō te compressor tīwiri me te PTO o mua mō ngā pūnaha waipēhi, e whakarite ana i te pai rawa atu me te iti o te ngaronga mana. Ka whakaratohia e te compressor e rua-wāhanga whakauru he 20m³/min nui o te hau i te 22 pae, e āhei ai te taputapu ki te pana i ngā hama 5-inihi (K5) i roto i te toka mārō (f=6-20) me te tere me te whai hua whakamiharo.
Ko te aunoatanga me te tika o ngā mahi te tino hira o te ZT12. Kei roto he pūnaha tiaki mīhini mō ngā rakau keri me te pūnaha ārai-aukati hiko-waipēhi e whakarite aunoa ana i te whāngai me te hurihanga kia kore ai e piri.

Kua hangaia te taiao whakahaere o te ZT12 mō te hua me te haumaru mō te wā roa. Ko te kāpata whānui, he hauhautanga, kua whai tiwhikete ROPS me FOPS katoa, e whakarato ana i te taumata teitei o te tiakitanga mai i ngā tūponotanga o te papa. I roto, ka taea e te kaiwhakahaere te uru atu ki tētahi huinga whakahaere hou e whakaatu ana i ngā rakau hari pairati waipēhi me tētahi pūnaha tohu koki/hohonu keri hei whiriwhiri mō te tino tika. Kei roto hoki i te taputapu he pūnaha whakahinuhinu hinu aunoa mō te aho keri, e whakarite ana i te pono mō te wā roa o ngā taputapu pau.
He tino pai te nekehanga mō tētahi mīhini 16,800kg. E 430mm te tawhiti whenua e tukuna ana e te anga ngokingoki me te 87KN te kaha o te kukume, e āhei ai te ZT12 ki te neke māia i runga i ngā papa keri pakari me ngā pari pari. Mā te motuka hurihuri taipana teitei (4000 N·m) me te pūnaha whāngai kaha (39 KN), ko te ZT12 te otinga "wiri me te pupuhi" tino pai mō ngā mahi keri nui puta noa i te ao.
