Whakaahuatanga Hua

Ngā poro hurihuri mō te poka keri hinu
1. Ko tēnei mata porotaka tricone mō te keri hinu e whakamahi ana i te hanganga peera roera hiri, i te mata porotaka tricone rānei he mea hiri whakarewa. Mēnā ka whakaritea ngā roera ki roto i ngā awaawa kua kōhao ki roto i te tinana kōne, ka nui ake te rahi o te pukapuka peera.
2. He mata mārō ngā mata o te peera pana, ā, he hangarau whakaiti waku te whakamahinga.
3. Kone poro raka, he pai mō te tere hurihuri teitei.
Ka taea e Weifang Far Eastern Machinery te tuku i te nuinga o ngā waehere IADC penei: Waehere IADC: 116 117 12 6127 136 137 216 217 226 226 316 317 326 327 336 337 115 125 135 215 225 235 315 325 417 427 437 517 527 537 617 627 637 737 837 832 415 425 435 445 525 625 635 416 427 436 446 447
