Ngā Mōhiotanga Noa mō te Whitiki Herea Ratchet

SHF:

Te kaha ā-ringa paerewa: Te kaha whakahaere ā-ringa o te 500N (50daN i runga i te tapanga).

STF:

Kaha kume paerewa: Kaha toenga i muri i te tukunga o te kakau o te whitiki ratchet.

Te roa:

Ko te ine i te totoro, i runga i tētahi kawenga kua hoatu, e whakaatuhia ana hei ōrau o te roa taketake kāore i utaina. Ka totoro ngā rauemi katoa e pāngia ana e te kume, ā, he rerekē ngā tere o te kume o ngā rauemi rerekē i runga i te kawenga kume kotahi.

Mō te whitiki ratchet, ko te roanga kei waenganui i te 4% ki te 7%.

Te pāmahana:

Kaua e whakamahia te whitiki here mā te whakamahi i te whatu polypropylene, polyester rānei i ngā pāmahana neke atu i te 90℃, i raro iho rānei i te -40℃.

Whakatika:

Kaua e whakatikatikaina te whatu, te whitiki ratchet, te matau, ngā tauira tuitui/tuitui rānei.

Paerewa:

Ko te EN 12195-2, AS/NZS 4380, me te WSTDA-T-1 he paerewa katoa e whakahaere ana i ngā whakaritenga, te whakamātautau, me te whakamahinga o ngā whitiki ratchet me ngā huinga here e whakamahia ana mō te pupuri i ngā utanga. Ahakoa he rite tonu te kaupapa, he rerekētanga kei runga i tō rātou takenga whenua, ngā whakaritenga motuhake, me ngā tikanga whakamātautau.
