He whānui noa iho ngā mōhiohio nei, e kapi ana i ngā kaupapa matua mō te whakamahinga haumaru o ngā Here mekameka. Tērā pea me tāpiri atu ēnei mōhiohio mō ngā whakamahinga motuhake. Tirohia hoki te aratohu whānui mō te pupuri kawenga, kei te whārangi e whai ake nei.
NGĀ WĀ KATOA:
Tirohia ngā here mekameka i mua i te whakamahinga.
● Tātaihia te kaha here e hiahiatia ana mō te tikanga here kawenga kua whiriwhiria.
● Tīpakohia te kaha me te maha o ngā here mekameka hei whakarato i te iti rawa o te kaha here kua tatauhia
● Me whakarite kia rawaka te kaha o ngā pū here o te waka me/ranei te kawenga.
● Tiakina te here mekameka mai i ngā taha iti o ngā radius, whakaitihia rānei te kaha here kia rite ki ngā tohutohu a te kaihanga.
● Me whakarite kia tika te kukū o ngā here mekameka.
● Kia tūpato i te wā e wetewete ana i ngā here mekameka mēnā kua kore e pumau te kawenga mai i te wā i whakamahia ai ngā here.
KAUA RAWA:
● Whakamahia ngā mekameka here hei hiki i te kawenga.
● Herea, herea, whakarerekētia rānei ngā here mekameka.
● Ngā here mekameka taumaha rawa.
● Whakamahia ngā here mekameka ki runga i te mata koi, kāore he parenga mata, kāore hoki e whakaiti i te kaha here.
● Whakatakotoria ngā here mekameka ki ngā matū, me te kore e kōrero ki te kaiwhakarato.
● Whakamahia ngā here mekameka kua hē ngā hononga mekameka, kua pakaru te ātete, kua pakaru ngā hononga pito, kua ngaro rānei te tohu tuakiri.
Te Kōwhiri i te Herenga Mekameka Tika
Ko te paerewa mō ngā here mekameka ko te BS EN 12195-3: 2001. E hiahiatia ana kia rite te mekameka ki te EN 818-2, me ngā wāhanga hono hoki kia rite ki te EN 1677-1, 2, 4 rānei e tika ana. Me whai taputapu whakau pērā i te raka haumaru ngā wāhanga hono me ngā wāhanga whakapoto.
Ko ēnei paerewa mō ngā tūemi taumata 8. He nui ake ngā taumata e tukuna ana e ētahi kaihanga, ā, he nui ake te kaha here mō ia rahi.
Kei te wātea ngā here mekameka i roto i ngā momo kaha me ngā roa, me ngā momo whirihoranga rerekē. Ko ētahi he mahi whānui. Ko ētahi he mahi motuhake.
Me tīmata te kōwhiringa mā te aromatawai i ngā kaha e pā ana ki te kawenga. Me tatau te kaha here e hiahiatia ana kia rite ki te BS EN 12195-1: 2010.
Muri iho, tirohia mēnā he kaha rawaka ngā pū here o te waka me/ranei te kawenga. Mēnā e tika ana, whakamahia he maha atu o ngā here hei hora i te kaha puta noa i ngā pū here maha.
Ka tohua ngā here mekameka ki tō rātou kaha here (LC). e whakaaturia ana i roto i te daN (teka Newton = 10 Newton) He kaha tēnei e rite ana ki te taumaha o te 1kg.
Te Whakamahi Haumaru i ngā Herenga Mekameka
Me whakarite kia tū tika te whakapūmau, kia kaua e piko ki te taha. Me whakarite kia kaua te mekameka e miro, e herea rānei, ā, kia tika te hononga o ngā hononga pito ki ngā pūwāhi here.
Mō ngā here wāhanga e rua, kia tino hototahi ngā wāhanga.
Me whakarite kia tiakina te mekameka mai i ngā taha koi, iti hoki o te pūtoro mā te whakamahi i ngā takai, i ngā parenga taha rānei e tika ana.
Kia mōhio: Tērā pea ka whakaaetia te whakamahi i ngā tohutohu a te kaihanga ki ngā taha iti o te pūtoro mena ka whakaitihia te kaha here.
Tirotiro me te Rokiroki i roto i te Ratonga
Ka pakaru pea ngā here mekameka mā te kume i te mekameka puta noa i ngā taha iti o te porowhita me te kore e tika te tiaki taha. Heoi, ka pakaru pea nā te neke o te kawenga i te wā e kawe ana, nō reira me tirotirohia i mua i ia whakamahinga.
Kaua ngā mekameka here e pāngia e ngā matū, inā koa ngā waikawa ka pakaru te hauwai. Mēnā ka pāngia ngā mekameka here, me horoi ngā here ki te wai mārama, ā, me waiho kia maroke noa iho. Ka kaha haere ngā matū ngoikore i te mimiti.
Me tirotirohia ngā here mekameka mō ngā tohu kino i mua i ia whakamahinga. Kaua e whakamahia te here mekameka mēnā ka kitea tētahi o ēnei hapa: ngā tohu kāore e taea te pānui; ngā hononga mekameka piko, roa, kōpiko rānei, ngā wāhanga hononga, ngā hononga pito rānei kua hē, ngā raka haumaru kāore i te whai hua, kua ngaro rānei.
Ka memeha haere ngā here mekameka i roto i te wā. E taunaki ana te LEEA kia tirohia e tētahi tangata mātau i te iti rawa i ia ono marama, ā, kia tuhia hoki ngā hua.
Me whakatika anake ngā here mekameka e te tangata whai pūkenga ki te mahi pera.
Mō te rokiroki mō te wā roa, me maroke, me ma, ā, me kore he poke i te wāhi rokiroki.
