Te Tiini Hine Whakanuia mo te Whakaoho Maena Whakanui
Te whakauru i a maatau mahi hou i roto i te umanga hiki me te whakaara, 16mm G80 Alloy Steel Chain Hoist Lifting Chain. I hangaia hei whakarato i te kaha me te pono, i hangaia tenei hua ki te whakatutuki i nga hiahia o te tini o nga momo mahi hiki.
Ko o tatou mekameka hiki he mea hanga mai i te maitai koranu G80 kounga teitei, e mohiotia ana mo te tino pakari me te whakaahuru kakahu. Ma te diameter o te 16mm, kua piki ake te kaha o te mekameka me te mauroa mo nga tono hiki taumaha.
Ko o tatou mekameka hiki he mea hanga mo te mahi maeneene me te pai o te hiki. Ko ia hononga he mea hanga tika me te whakamatau kia pai ai te mahi me te haumaru. He maamaa te mekameka, he maamaa me te ngawari ki te hapai, ka whakaiti i te ahotea o te kaiwhakahaere i te wa e hiki ana.
Ko te maitai koranu G80 e whakamahia ana i roto i o tatou mekameka hiki he tino pai te aukati waikura, he pai mo te whakamahi i waho me nga taiao kino. Ma tenei ka taea e te mekameka te tu ki nga ahuatanga huarere katoa, ka roa ake tona oranga me te whakaiti i te hiahia mo te tiaki auau.
Ko te haumaru te kaupapa matua o nga mahi hiki, a ko o tatou mekameka hiki i hangaia ma tenei whakaaro. I hangaia me te take haumaru o te 4: 1, ko te tikanga ka taea e ia te tu ki te wha nga wa te nui o te kawenga mahi, me te whakarite i te tino haumaru i te wa e hapai ana.
Ko te 16mm G80 Alloy Steel Chain Hoist Lifting Lifting Link Chain he maha nga waahanga ka taea te whakamahi i roto i nga umanga maha penei i te hangahanga, hangahanga me te kawe waka. He pai mo nga momo tono penei i te hiki miihini taumaha, te pupuri i nga uta me nga kaupapa rewa.
Hei mutunga, ko ta maatau 16mm G80 Alloy Steel Chain Hoist Lifting Chain e whakakotahi ana i te kaha, te pono me nga waahanga haumaru hei whakarato i nga mahi pai ake i nga mahi hiki. Na te hanga o te kounga teitei me te mauroa, kua hangaia tenei mekameka hiki hei hoa pono mo o hiahia hiki katoa.
