Hammer DTH Pee-rangi iti
Te raro-te-pokadth hamahe taputapu e whakamahi ana i te hau kōpeke hei puna hiko me te whakamahi i te nekehanga tauutuutu o te piston i roto i tehamaki te paopao i te moka wiri kia pakaru te toka. Te raro-te-pokadth hamahe taputapu mahi o te keri raro-te-poka. E ai ki te pehanga mahi o tedth hama, ka taea te wehea ki te pehanga itidth hama(ko te pehanga mahi ko 0.5 ~ 0.7Mpa), te pehanga reodth hama(0.7~1.2Mpa) me te pehanga teiteidth hama(i runga ake i te 1.2Mpa); e ai ki te tikanga tohatoha hau me nga ahuatanga hanganga o tedth hama, Ka taea te wehea ki nga momo maataki me nga momo korepu; e ai ki te hanganga o te pokapū i roto i te poka o te raro-te-pokadth hama, ka taea te wehea ki raro-te-poka noadth hamame te huri i te tohanga ki raro-te-pokadth hama.
Taupānga:
E whakamahia nuitia ana i roto i te rua tuwhera me te keri o raro o te whenua, te hanga punga, te keri me te keri toka, te keri waiariki, te hanga miihini keri toka me te hanga miihini nui., etc.
Ngā āhuatanga
1 Ko te pehanga hau whakahaere kei waenganui i te 0.5Mpa me0.7Mpa
2 Hama korere.
3 Hanganga ngawari, ngawari ki te huihui me te wetewete, te roa o te oranga.
4 He nui ake te kaha o te paanga me te tere keri.
5 Whakaitihia te hau me te iti o te hinu hinu. Ka taea te keri i te kohao ki runga i te taki taki kia pai ake ai te rere o nga haea.
6 He pai rawa mo te keri.
