E hia te rahi o ngā wira keri nui rawa atu?
Ko ngā wira keri nui rawa atu e whakamahia ana i roto i ngā taraka keri me ngā taputapu keri taumaha. Ko te tikanga, he mea hanga ēnei wira hei kawe i ngā kawenga tino teitei, me te whakarato i te mahi pumau i raro i ngā āhuatanga tino kino. I te mea ko te nuinga o ngā mahi keri he kawe i te nui o te konganuku, ngā taputapu me ngā rauemi, ā, he maha ngā wā ka uru atu ki ēnei mahi kawe he kawenga taumaha me te rahi rawa, ko te whakamahinga o ngā wira nui he mea nui hei whakarite i te haumaru, te whai hua me te pumau.
Ko ētahi o ngā whakatakotoranga potae keri nui rawa atu o te ao i ēnei rā, ka taea e ngā potae keri nui rawa atu te tae ki te diameter o te 4.5 mita (tata ki te 14.8 putu), pērā i ngā potae kei runga i te Caterpillar 797F. He whānui rawa te whānui o ēnei awhi, he maha ngā wā he 36 inihi, he whānui ake rānei, he pai mō ngā potae nunui.
Hei tauira, ko te rahi o te potae o te taraka keri nui rawa atu, ko te Caterpillar 797F, ko te diameter o ēnei potae he 4.5 mita, ā, ko te whānui he 59 inihi (tata ki te 1.5 mita), ā, ko te taumaha o ia potae he 5000-6000 kg. Ka whakamahia ēnei taraka hei kawe i te nui o te konganuku i roto i ngā maina tuwhera, ā, ka taea te kawe i te taumaha tae atu ki te 400 tana.
He iti ngā āhuatanga o ēnei potae keri nui rawa atu: Ko te whānui o ngā potae tino nui rawa atu i waenga i te 4.5 mita (tata ki te 14.8 putu) me te 5 mita (16.4 putu) te whānui, ā, neke atu i te 50 inihi (1.27 mita) te whānui o ngā potae. Ka taea e ēnei potae te kawe i ngā kawenga tino taumaha, ā, he maha ngā wā ka whakamahia i roto i ngā taraka keri nui rawa atu o te ao, he 400 tana, neke atu rānei te kaha kawenga.
Ko te nuinga o te wā ka whakamahia ēnei potae nunui ki ngā maina tuwhera, ki ngā wāhi keri hohonu me ngā wāhi whakaputa hinu nui, ā, he whānuitia te whakamahinga ki ngā taraka keri nunui me ngā taputapu kawe. Me nui rawa ngā kawenga e hiahiatia ana, he nui ake te horahanga pa, he ngāwari ki te urutau ki ngā whenua uaua, ā, he tino pakari me te ātete ki te pānga.
Ko ngā wira keri nui rawa atu o te ao (pērā i ngā mea e whakamahia ana i roto i ngā taraka keri pērā i a Caterpillar 797F, BelAZ 75710 rānei) ka taea te whānui mai i te 4.5 mita ki te 4.8 mita te whānui, ā, neke atu i te 50 inihi te whānui. Ka taea e ēnei potae nunui te kawe i ngā kawenga tino teitei, ā, e whakamahia ana mō ngā waka kawe taumaha rawa atu i roto i ngā maina tuwhera. Ka taea e rātou te tu atu ki ngā kawenga neke atu i te 400 tana hei whakarite i te whai huatanga me te haumaru i te wā e kawe ana i te konganuku. Kua hoahoatia, kua hangaia hoki ēnei potae me ngā awhi me te whakaaro ki ngā taiao tino kino me ngā whakaritenga kawenga teitei, ā, he wāhanga matua nui i roto i te umanga keri.
E whakarato ana tā mātou kamupene i ngā taraka keri taumaha Caterpillar 777 me19.50-49/4.0 ngā awhie taea ai te kawe i ngā kawenga tino tiketike.
He taraka keri rahi-waenga te CAT 777, ā, ko te kaha uta mōrahi he 100-110 tāne pea. Nā tōna kaha uta he mea pai mō te kawe i te konganuku me ētahi atu rauemi i roto i ngā maina rahi-waenga, he pai mō ngā wāhi he taumaha ngā kawenga engari he iti noa te rahi o ngā waka. He whānuitia te whakamahinga o te CAT 777 i roto i ngā maina tuwhera hei kawe i te konganuku, te onepu me ētahi atu rauemi taumaha. Hei tētahi o ngā tauira tawhito a Caterpillar, he whānuitia ngā tono a te raupapa 777 i roto i ngā kaupapa keri me te hanga puta noa i te ao.
Nā ngā āhuatanga motuhake e whakamahia ai te CAT 777, kua hangaia ngā awhi e whakamahia ana i roto i tēnei waka hei kawe i ngā kawenga tino nui. Hei taraka keri rahi-waenga, me tutuki i ngā awhi me ngā potae o te 777 ngā whakaritenga kawenga teitei o te waka, engari me whakarato hoki i te pai o te kukume me te pakari i roto i ngā taiao keri uaua.
I runga i tēnei whakaritenga motuhake, kua whakawhanakehia, kua hoahoatia hoki e tā mātou kamupeneNgā awhi rahi 19.50-49/4.0e tika ana mō tēnei waka.
He aha ngā āhuatanga o ngā awhi 19.50-49/4.0?
Ko te 19.50-49/4.0 i hangaia e tā mātou kamupene he whakatakotoranga mō ngā awhi keri, e whakamahia ana mō ngā waka kawe keri, pērā i ngā taraka keri nui, ngā uta wira me ētahi atu mīhini taumaha. E ōrite ana tēnei whakatakotoranga o ngā awhi ki ngā potae keri, ā, he rahi me ngā āhuatanga hoahoa motuhake hei urutau ki ngā kawenga teitei, ki ngā whenua uaua me ngā whakaritenga mahi roa i roto i ngā taiao keri.
Nā te hoahoa awhi whānui me te whānui i hangaia mō ngā awhi 19.50-49/4.0, ka taea te tautoko i te whakamahinga o ngā potae keri nui, ā, he pai hoki mō te kawe i ngā kawenga keri nui. Ka taea e ia te tohatoha i te taumaha me te whakaiti i te pēhanga whenua mō ia wāhanga horahanga, ā, ka pai ake te pumau me te kukume.
He pai te kaha o tēnei awhi ki te kawe i ngā tekau ki ngā rau tana o te konganuku, inā koa mō ngā taraka keri rahi me te rahi.
I roto i ngā taiao maina uaua, he kaha te ātete o te rauemi kaha-teitei e whakamahia ana i roto i tēnei awhi ki ngā pānga me te ātete ki te kakahu. He tino pai tēnei awhi mō ngā maina, e kī ana i ngā arai pēnei i te kōhatu, te paru, te onepu me te puehu. Ko ngā potae e ōrite ana ki te awhi 19.50-49/4.0 he nui te wāhi pa, ā, he kaha te ātete ki te poka, ka taea te pupuri i te kaha o te kukume me te pumau i te wā e taraiwa ana i runga i ngā rori maina taratara.
Ka taea e te awhi whānui te whakamarara i te kawenga me te whakaiti i te taumahatanga ki runga i ngā potae o te taraka keri. Ina koa i roto i te kawe kawenga taumaha, ka āwhina tēnei hoahoa ki te whakaiti i te pakaru o ngā potae me te mōrearea o te pahū o ngā potae. Mā te whakataurite i ngā awhi whānui me ngā potae ka pai ake te pumau o te taraka i te wā e kawe ana, ina koa i roto i ngā whenua uaua, ka taea te whakaiti i te mōrearea o te hurihuri me te paheke. I taua wā anō, ka whakaratohia e te awhi whānui he wāhi pa ki te whenua, ka pai ake te toia o te waka i runga i te whenua ngohengohe, pahekeheke rānei, he mea tino pai mō te whakamahi i runga i te whenua uaua pēnei i te paru, te oneone ngohengohe, te kirikiri rānei i roto i ngā maina.
Ko ngā awhi o tēnei whakatakotoranga he mea hanga i te maitai, i te koranu rānei, he ātete ki te waikura, he ātete hoki ki te pānga, ā, ka taea te tu atu i te horo o ngā āhuatanga kino o te taiao keri, ā, ka roa ake te ora o te mahi. Ka pāngia ngā waka keri e ngā wiri me ngā ru i te wā e mahi ana, ā, ka taea e ngā awhi whānui, pakari hoki te mimiti i te pānga me te whakaiti i te kino o ngā potae.
Ko te tikanga, ka whakamahia tēnei awhi me ngā potae keri nui, pērā i te 29.5R25, te 33.00R49 rānei, ka taea te whakatutuki i ngā hiahia o ngā kawenga nui me ngā mahi tere-tiketike, ā, ka whakapai ake i te whai huatanga o te mahi a te waka.
Ko te awhi keri 19.50-49/4.0 i hangaia e tā mātou kamupene he awhi keri taumaha, he pumau, he pakari hoki e whakamahia whānuitia ana i roto i ngā taraka kawe keri me ētahi atu taputapu keri taumaha. Mā tōna whānui me tōna hoahoa awhi whānui ka taea te whakarato i tētahi wāhi pa whenua nui ake, te tautoko i ngā kawenga taumaha, me te whakarite kia pumau te taraiwa o ngā waka i roto i ngā taiao keri uaua. Nā tōna kaha teitei me tōna ātete pānga, he tino pai mō te mahi roa i roto i ngā taiao taumaha me ngā taiao kino pērā i ngā maina.
Mā tēnei hoahoa, ka taea e te CAT 777 te whakarato i ngā āheinga kawe waka whai hua, pumau hoki i roto i ngā taiao maina uaua, kia roa ai te wā e whakamahia ana te waka me te pono hoki.
