Here taura

Ko te here taura (e mōhiotia ana ko te here ngongo, te here reti) he momo here, hei pupuri i ngā taonga, ko ngā taura hiko me ngā waea te nuinga. Nā te iti o te utu, te ngāwari o te whakamahi, me te kaha o te here, he maha ngā whakamahinga o ngā here taura.

Ko te here taura noa, he mea hanga ki te nairona, he wāhanga rīpene ngāwari me ngā niho e hono ana ki te matihao i te pane hei hanga i te ratchet kia mau ai te here taura i te wa e kumea ana te pito kore utu o te wāhanga rīpene, ā, e kore e wetekina. Ko ētahi here he ripa ka taea te pēhi hei tuku i te ratchet kia taea ai te wetekina, te tango rānei i te here, ā, tera pea ka taea te whakamahi anō. Ko ngā momo kowiri tira, ko ētahi kua pania ki te kirihou pakari, e pai ana mō ngā mahi o waho me ngā taiao morearea.

Te hoahoa me te whakamahinga

Ko te here taura tino noa he rīpene nairona ngāwari me te whatanga taputapu whakauru, ā, i tetahi pito he ratchet i roto i tētahi pouaka iti tuwhera. Kia kumea te pito koi o te here taura mā roto i te pouaka, ā, kia hipa i te ratchet, ka āraia kei kumea whakamuri; ko te koropiko hua ka taea anake te kumea kia kikī ake. Mā tēnei ka taea te here tahi i ētahi taura hei paihere taura, hei hanga rānei i tētahi rākau taura.

Ka taea te whakamahi i tētahi taputapu whakawhāiti here taura hei whakamau i tētahi here taura me tētahi taumata whakawhāiti motuhake. Ka taea e te taputapu te tapahi i te hiku tāpiri kia rite ki te pane kia kore ai e puta he mata koi e whara ai. Ka whakahaerehia ngā taputapu māmā mā te pēhi i te kakau ki ngā maihao, ko ngā taputapu taumaha ka taea te whakamahi i te hau pēhi, i te solenoid rānei, hei ārai i ngā whara pēhanga auau.

Hei whakanui ake i te ātete ki te hihi ultraviolet i roto i ngā mahi o waho, ka whakamahia te nairona kei roto i te iti rawa o te 2% te pango waro hei tiaki i ngā mekameka polymer me te whakaroa i te roa o te mahi a te here taura. [e hiahiatia ana te tohutoro] Ka tukuna ngā here taura kikorangi ki te umanga kai, ā, kei roto he tāpiringa whakarewa kia taea ai te kite mā ngā taputapu whakarewa ahumahi.

Kei te wātea hoki ngā here taura kowiri tira mō ngā mahi ātete mura—kei te wātea ngā here kowiri tira pania hei ārai i te whakaekenga o te konupūmā mai i ngā konganuku rerekē (hei tauira, te paepae taura kua pania ki te konutea).

Hītori

I hangaia tuatahitia ngā here taura e Thomas & Betts, he kamupene hiko, i te tau 1958 i raro i te ingoa waitohu Ty-Rap. I te tīmatanga i hangaia mō ngā here waea rererangi. I whakamahia he niho whakarewa i te hoahoa taketake, ā, kei te wātea tonu ēnei. Nō muri mai ka huri ngā kaihanga ki te hoahoa nairona/kirihou.

I roto i ngā tau kua pahure ake nei, kua whakawhānuihia te hoahoa, ā, kua whakawhanakehia hei maha ngā hua rerekē. Ko tētahi tauira ko te koropiko raka-ake i whakawhanakehia hei huarahi kē atu ki te tuitui taura-pukoro i roto i te anastomosis koroni.

I mahi a Maurus C. Logan, te kaihanga o ngā here taura a Ty-Rap, mā Thomas & Betts, ā, i mutu tana mahi ki te kamupene hei Tumuaki Tuarua mō te Rangahau me te Whakawhanake. I a ia e mahi ana i Thomas & Betts, i whai wāhi ia ki te whakawhanaketanga me te hokohoko i ngā hua angitu maha a Thomas & Betts. I mate a Logan i te 12 o Noema 2007, i te 86 o ōna tau.

I puta mai te whakaaro mō te here taura ki a Logan i a ia e tirotiro haere ana i tētahi whare hanga waka rererangi a Boeing i te tau 1956. He mahi uaua, he mahi taipitopito hoki te whakapūtanga waea waka rererangi, he mano putu te roa o te waea i whakaritea ki runga i ngā rau rakau papa rakau 50 putu te roa, ā, i puritia ki te taura nairona kua herea, kua pania ki te ware pi, kua whiria. Me kume ia pona kia mau mā te takai i te taura ki te maihao o te tangata, ā, i ētahi wā ka tapahia ngā maihao o te kaiwhakahaere kia puta rā anō he kiri matotoru, he "ringa hāmipeka" rānei. I whakapono a Logan me whai huarahi ngāwari ake, me whai murunga hara, hei whakatutuki i tēnei mahi nui.

Mō ngā tau e rua i muri mai, i whakamātau a Logan i ngā taputapu me ngā rauemi maha. I te 24 o Hune, 1958, i tukuna he mana pateni mō te here taura Ty-Rap.
