Ngā Kēne Jib Whakatutukitanga Nui e Mau ana ki te Pou

He tino pai te kerēne jib e mau ana i te pou mō ngā wāhi mahi iti, whaiti hoki, ā, ka māmā ake te whakamahi ina whakahaerehia i te kaha nui ake, i te whānuitanga toronga roa ake rānei. Kei roto i te huinga taputapu katoa ko te pou o runga, te pou o raro, te kurupae matua, te tokotoko here kurupae matua, te tikanga hiki, te tikanga wete, te pūnaha hiko, te arawhata me te papa tiaki. I roto i ēnei, ka taea e te taputapu wete kua tāutahia ki te pou te huri i te kurupae matua ki te 360° hei hiki i ngā mea, ka whakanui ake i te wāhi hiki me te whānuitanga.

Ko te turanga i te pito o raro o te pou ka mau ki te turanga raima mā roto i ngā pūtu punga, ā, ka peia e te motuka te taputapu taraiwa whakaiti hei huri i te cantilever, ā, ka mahi te hiki hiko ki mua, ki muri i runga i te cantilever I-beam. Ka taea e te crane jib pou te āwhina i a koe ki te whakapoto i te wā whakarite whakaputa me te wā mahi kore hua, me te whakaiti i te tatari koretake.

Me whai ngā ture e whai ake nei mō te whakamahinga o te crane poutū:

1. Me mōhio te kaiwhakahaere ki te hanganga me te mahi a te kereini jib. Ka taea te whakahaere motuhake i te kereini i muri i te whiwhinga i te whakangungu me te aromatawai, ā, me whai i ngā ture haumaru.

2. I mua i ia whakamahinga, tirohia mēnā he pai te pūnaha tuku, ā, mēnā he tairongo, he pono hoki te pana haumaru.

3. Me kore he wiri me te haruru rerekē i te kerēne jib i te wā e whakahaerehia ana.

4. Kāore rawa e whakaaetia te whakamahi i te kerēni cantilever me te taumaha rawa, ā, me whai i ngā whakaritenga "tekau kāore e taea te hapai" i roto i ngā ture whakahaere haumaru kerēni.

5. Ina tata te cantilever, te hiki rānei ki te pito whakamutunga, me whakaiti te tere. Kāore e whakaaetia kia whakamahia te rohe pito whakamutunga hei huarahi whakamutu.

6. Ngā whakatūpato mō ngā taputapu hiko o te kereini jib e mau ana i te pou i te wā e whakahaerehia ana:

① Mehemea kei te wera rawa te motuka, kei te wiri rerekē, kei te haruru rānei;

② Tirohia mēnā he haruru rerekē te pouaka whakahaere;

③ Mehemea he wetekina te waea, ā, he waku anō hoki;

④ Mēnā ka pakaru te mīhini, pērā i te wera rawa o te motuka, te haruru rerekē, te paoa mai i te ara iahiko me te pouaka tohatoha, me ētahi atu, katihia tonutia te mīhini, ka tapahia te pūtake hiko hei tiaki.
