I te ao o te whakahaere rauemi me te kawe waka, he mea nui te mahi a ngā kerēni i roto i te kawe haumaru i ngā utanga. E rua ngā momo kerēni e whakamahia whānuitia ana i ngā tauranga me ngā taunga ipu: ko ngā kerēni gantry kua whakakīia ki te rapa (RTG) me ngā kerēni gantry kua whakakīia ki te reriwe (RMG). Ahakoa he rite tonu ngā mahi a ēnei e rua, he rerekē ngā āhuatanga me ngā whakamahinga o ia kerēni.
Ngā RTGkua hangaia hei whakahaere i runga i ngā potae rapa, e āhei ai rātou ki te neke haere noa i te papa. Mā tēnei nekehanga ka taea e te kerēne RTG te kawe i ngā ipu ki ngā wāhi rerekē me te kore e herea ki tētahi ara pakari. He tino pai tēnei i ngā taiao he iti te wāhi, nā te mea ka taea te karo i ngā arai, ā, ka taea te whakakapi ina hiahiatia. He maha ngā wā ka whakamahia ngā kerēne RTG i ngā taunga whakawhiti-momo me ngā tauranga iti ake, he mea nui te ngāwari me te urutau.
I tētahi atu taha, heRMGkua whakanohoia ki runga i ngā rēra, ā, ka whakahaerehia i runga i tētahi ara pumau. Mā te hoahoa ka nui ake te ngāwari me te mārama o te whakahaere rauemi. Ko ngā kerēni RMG te tikanga e whakamahia ana mō ngā taonga ipu nui e hiahia ana kia maha ngā mahi. Mā te āhua o te rēra ka taea te hiki me te neke i te ipu i ngā tawhiti roa, he mea pai mō te rokiroki me te whare putunga.
Ko tētahi atu rerekētanga nui ko te tere me te mana. He nui ake te kaha hiki o ngā RMG, ā, ka taea te mahi i ngā tere teitei ake i ngā RTG. Nā tēnei ka pai ngā kerēne RMG mō ngā mahi nunui e iti ana te wāhi.
Hei whakarāpopototanga, he mea nui ngā RTG me ngā RMG i roto i te whakahaere ipu, engari nā ō rāua rerekētanga o te mahi, te hoahoa, me ngā āheinga mahi e pai ai rāua mō ngā taiao me ngā whakaritenga rerekē. Mā te mārama ki ngā rerekētanga ka āwhina i ngā kaiwhakahaere kerēni neke ki te whiriwhiri i te kerēni tika mō ā rātou hiahia, ka whakapiki ake i te hua me te whai huatanga o ā rātou taputapu whakahaere ipu.
