Ngā mekameka kawe(e kiia ana hoki ko ngā mekameka here, ngā mekameka here, ngā mekameka here rānei) he mekameka maitai koranu kaha-teitei e whakamahia ana hei pupuri i ngā utanga taumaha, koretake, utu nui rānei i te wā e kawe ana i ngā utanga rori. Ka honoa ki ngā taputapu pēnei i ngā here, ngā matau, me ngā mekameka, ka hangaia he pūnaha here kawenga nui e ārai ana i te nekenga utanga, te kino, me ngā aituā.
Ko ngā tono matua ko:
- Te tiaki i ngā taputapu hanga/taumaha (ngā keri, ngā pūrutō)
- Te whakau i ngā koiri rino, ngā kurupae hanganga, me ngā paipa raima
- Te kawe i ngā mīhini, ngā waeine ahumahi, ngā kawenga nunui rawa rānei
- Ngā taiao mōrearea nui (ngā taha koi, ngā taumaha rawa, te wera/te waku)
Te Hiranga o te whakatinanatanga o ngā mekameka kawe:
- Haumaru:Ārai i te nekehanga kawenga e hua ai ngā takahurihuri, ngā maripi rānei.
- Te Whakatutukitanga:E tutuki ana i ngā paerewa ture (hei tauira, FMCSA i USA, EN 12195-3 i EU).
- Te Tiakitanga o ngā Rawa:Ka whakaiti i te kino ki ngā utanga/taraka.
- Te Whai Hua o te Utu:Ka taea te whakamahi anō, ā, ka roa te mau mēnā ka tiakina tika.
Anei tētahi aratohu whānui mō te kawe/here mekameka mō te pupuri i ngā utanga taraka, e aro ana ki ētahi o ngā kaupapa kua whakaarohia paitia e ngā umanga:
| Āhuatanga | Ngā Mekameka Kawe | Ngā taura whatu |
|---|---|---|
| Rauemi | Rino koranu (Ngā tohu G70, G80, G100) | Whariki polyester/nailona |
| Pai rawa atu mō | Ngā kawenga koi, ngā taumaha tino taumaha (>10T), te waku/te pakū nui, te wera nui | He mata ngawari, he utanga mama, |
| Kaha | Teitei rawa o te WLL (20,000+ lbs), he iti noa te totoro | WLL (tae atu ki te 15,000 lbs), he ngāwari iti |
| Ātete ki te Kino | Ātete ki te tapahi, te pakū, te pirau UV | Ngāwari ki ngā motu, ngā matū, te memeha o te hihi UV |
| Taiao | Ngā āhuatanga mākū, hinuhinu, wera, whakakoi rānei | Ngā taiao maroke, whakahaeretia |
| Ngā Whakamahinga Noa | Ngā koiri rino, ngā mīhini hanga, te rino hanganga taumaha | Taonga whare, karāhe, mata peita |
Rerekētanga Matua:He tino pai ngā mekameka mō ngā kawenga taumaha, whakakoi, koi rānei, ina he mea nui te pakari; ka tiakina e te whatu ngā mata pakarukaru, ā, he mama ake/ngāwari ake te whakahaere.
A. Kōwhiringa Mekameka
1. Ngā Mea Hiranga mō te Tohu:
-G70 (Mekameka Kawe)Whakamahinga whānui, ngāwari te nekeneke.
-G80 (Mekameka Hiki):He kaha ake, he mea noa mō te whakau.
-G100:Te ōwehenga kaha-ki-taumaha teitei rawa (whakamahia me ngā taputapu hototahi).
- Me whakataurite tonu te taumata o te mekameka ki te taumata taputapu.
2. Rahi me te WLL:
- Tātaihia te tapeke o te taumahatanga e hiahiatia ana (e ai ki ngā ture pēnei i te EN 12195-3, FMCSA rānei).
- Tauira: Ko te kawenga 20,000 pauna me ≥5,000 pauna te kumenga mō ia mekameka (tauwehenga haumaru 4:1).
- Whakamahia ngā mekameka me te WLL ≥ kua tatauhia te kume (hei tauira, mekameka G80 5/16": WLL 4,700 lbs).
B. Kōwhiringa Taputapu
- Ngā Here:
Ngā Herenga Rātiti: He tino tika te kume, he haumaru ake te whakahaere (he pai mō ngā kawenga nui).
Ngā Here Rīwai: Tere ake, engari he mōrearea kei pakaru whakamuri (me whakangungu).
- Ngā matau/Ngā āpitihanga:
Matau Hopu: Hono atu ki ngā hononga mekameka.
Matau Paheke: Punga ki ngā pūwāhi pumau (hei tauira, te anga taraka).
Ngā matau-C/Ngā hononga matau-C: Mō ngā tāpiringa motuhake (hei tauira, ngā kanohi koiri maitai).
- Ngā Taputapu Tāpiri: Ngā parenga taha, ngā aroturuki kume, ngā mekameka.
C. Ngā Whirihoranga Motuhake mō te Utaina
- Ngā Mīhini Hanga (hei tauira, te Keri):Ngā mekameka G80 (3/8"+) me ngā here ratchet;Whakamaua ngā ara/wira me ngā pūwāhi whakapiringa; ārai i te nekehanga o te hononga.
- Ngā Koiri Rino:Ngā mekameka G100 me ngā matau-C, ngā here rānei;Whakamahia te miro "ahua-8" mā roto i te kanohi koiri.
- Ngā Kurupae Hanganga:Ngā mekameka G70/G80 me ngā here rakau hei ārai i te paheke;Mekameka whakawhiti i ngā koki ≥45° hei pumau i te taha.
- Ngā Paipa Konukura: Ngā pito ārai me ngā mekameka i runga i te paipa i ngā koki 30°-60°.
A. Tirotiro (I mua/I muri i ia Whakamahinga)
- Ngā Hononga Mekameka:Whakakāhoretia mēnā: Kua totorohia ≥3% o te roa, ngā ngatata, ngā pokapoka >10% o te whānui o te hononga, te tauhiuhi o te whakarewa, te waikura nui.
- Ngā matau/ngā mekameka:Whakakāhoretia mēnā: He piko, he nui ake i te 15% te pikinga o te whakatuwheratanga o te korokoro, he ngatata, he ngaro ngā raka haumaru.
- Ngā Here:Ākiritia mēnā: Kua piko te kakau/tinana, kua tawhito ngā pae/taputapu, kua korekore ngā pūtu, kua waikura te pūnaha ratchet.
- Whānui:Tirohia mēnā he pakaru i ngā wāhi e pā ana (hei tauira, te wāhi e pā ana te mekameka ki te kawenga);Manatokohia ngā tohu WLL me ngā tāmati māka e mārama ana.
B. Ngā Aratohu Whakakapinga
- Whakakapinga Ā-ture:Kāore e taea te pānui i ngā kapiti e kitea ana, te roanga, te tohu rānei o te tohu;Ngā matau/herehere kua piko >10° mai i te āhua taketake;Te pakaru o te hononga mekameka >15% o te diameter taketake.
- Te Tiaki Ārai:Whakahinuhinuhia ngā here ratchet ia marama;Whakakapia ngā here i ia 3–5 tau (ahakoa kāore i pakaru; kāore e kitea te pakaru o roto);Whakamutua ngā mekameka i muri i te 5–7 tau o te whakamahinga nui (tirotiro tuhinga).
C. Ngā tuhinga
- Puritia ngā rātaka me ngā rā, te ingoa o te kaitirotiro, ngā kitenga, me ngā mahi kua mahia.
- Whāia ngā paerewa: ASME B30.9 (Ngā taura here), OSHA 1910.184, EN 12195-3
