Ko JinJia he tohunga i ngā kōwhaiwhai hīroki. Ko te hīroki he rangahau e whakapuaki ana i te whakamahi i ngā wai kia puta ai te mōhiotanga. Ko te whakaae a JinJia ki ngā whiu kēmu e whakamahi ana i ngā wai me ngā pūnaha hei whakatupu, hei whakangungu i ngā rupu nui. He mea nui rawa ko ngā pū hīroki i waihanga e rātou. Ka whakarotoroto ēnei pū i te take hokihei hei whakatupu i tētahi tahuhu, ka taea e rātou te whakatupu i ngā mea, pērā i tētahi roa, tētahi pūkawekawe, ā, atu anō. E whai take ana ngā pū hīroki i tēnei wā, inā e āheinga ai rātou i ngā mīhini katoa kia mahi noa iho.
Kāore te kahi i runga i ngā pū hīroki i te waehanga o te mahi. Ko te pai tonu te whakatipu, e ai ki tētahi wā, ko te haere iti! Nā reira, ko ngā pū hīroki iti kahi he mea nui. Ko te pū iti kahi ka tiakina i te mana whenua, ka pai ake hoki i te whakamahi wai. Ko tēnei he pai mo te ao, nā te mea ka whakamahi mai rātou i te iti o ngā taonga, ka taea hoki e rātou te tiakina i ngā utu ēnei hei whakamahi i te huringa. Ā, ka taea e mātau tēnei i te pai me te whakaaro pai i ngā pū hīroki iti kahi.
Ko tēnā te take i heke ai ngā mota hidenaika waewae iti hei whiwhiā i roto i ētahi atu rōpū mahi, nā te maha o ngā paihana e noho mai ana ki a rātou. He paihana nui he mea ka whakaae mai ki a tātou kia hanga i ngā hītori me ngā hiahia e hiahia ana tātou ki reira. Ka hiahia tātou kia piki anō te mea, ko tā tātou whiringa pai ka kitea he mota hidenaika waewae iti. Ko tēnei e whai ana i te whakamahere pai mō ngā mahi e mahi ana i te wairua me te tino matataki. Nā ēnei mota hoki te pai mō ngā mahi nui, pērā i te kuhu i ngā mea rahi rānei, me te porotē i ngā mea kiko nui pērā i ngā whatu rānei. Ka taea e rātou ngā mahi nui e whai ana, kaore i taea e ngā mota iti.
Me pēhea rānei ngā mota hidraulika he wāhi mōhuhu iti, nō te mea ka taea e mātou kia whakahaere i a rātau. Ko tēnei ēnei tūranga e taea ai e mātou kia whakariterite i ō rātau wā mo ā mātou hiahia—wāhi mōhuhu rerekē rānei. Ki te whakamahi i te mana matua mēkanika me ētahi take whakahaere iti, ka taea e koe te whakarerekē i te waehu o ngā pūngao ki te hanga i tētahi mota e āhei ana ki te huri i te wā e hiahiatia ana e koe. Nō ēnei mahi nui nui, he mea nui kia whakawheowheo i ngā mea katoa i te wā tika, whakatakoto i ngā hītori—ko tēnei tētahi o ngā mahi mō ngā wīwī, ko tō rātau āhua ki te whakahaere i te wā e hiahia ana hei tūponotanga, pērā i ngā robot kāore e taea te wherohero, ranei ko ngā pariha e hanga mai i ngā mahi. Ko tēnei i roto i tō mātou hiahia kia taea tēnei, nā tēnei ka whiwhi mātou i te wehewehe me te whai hua i te mahi.
Engari, he aha rānei, pēhea rānei e mahi ana ēnei motokakai? Ka taea e mātou te kite i te nui o ngā whatu kei roto i te motokakai hydraulics, kua mahi ngākore ki tahi hei whakaatu i te tahuri o te pū. Inahea atu, ka whakamahia te pihinga i ēnei momo motokakai kē kia tahuri te wai ki waenganui i ngā wāhi, nō reira ka whakamahia ētahi atu i te kauwhanganui hei whakatata ki te porowhītiti o te wai. Ki te mea ko ēnei motokakai he maha ngā huarahi, kua whai mana a JinJia ki te hanga i ngā motokakai hydraulics iti haere me ngā āhuatanga matua, ā, he mihi nui hoki i te rōpū i te aha i te paetae. I whakahēmiahia e rātau te whakatū i ngā motokakai pai rawa ā-momo me te whakapai.
Ko te take, hei whiwhi koutou i ngā mōhiohinga mō tōu mota hydraulics rahinga, e ai ki ēnei tip ka taea e koe. Whakamahi i te wai pai mo to mota tinana/make tuatahi. Kotahi rawa atu ngā wai hydraulics, me utu hoki i ngā momo wai hydraulics e pai ana ki te mahi pai, koia nei, mēnā ka whakamahia e koe te he, ka noho kino rānei te mota. Tuarua, ko te whakahaere i to mota me te whaihere herehere taumata. Ko te whakawhitiwhiti i ngā pūtake mota he mea nui. Whakamahi i to haerenga i te tika tonu mo te mahi kei a koe. Ki te koha mai i te mota pai rawa atu ko te whakamahi pai, ka whakaanga koe i to whakangao, ka mahi ano hoki ia ki te pai.
