Ndi zida ziti zomwe zimayenera kugwiritsidwa ntchito pobowola mu geology yovuta kwambiri

1. Chombo chobowola chimakhala ndi mikwingwirima kapena kelly bar, yomwe imatha kukumana ndi mulu wa mulu ndi kutalika kwa mulu.

2. Kelly Bar: sankhani mtundu wa chitoliro chobowola molingana ndi mphamvu ya thanthwe lolimba kwambiri (mwachitsanzo, mita imodzi m'mimba mwake mwa mulu), mphamvu yake yomaliza ndiyotsika kuposa 500 kPa yokhala ndi friction kelly bar; kuposa 500 kPa yokhala ndi kelly bar yolowerana.

3. Zida zobowolera: Miyala yambiri yosalimba imatha kubowoledwa ndi ndowa yapawiri ya mano chipolopolo; zida zobowola zamitundu iwiri zozungulira zingagwiritsidwenso ntchito pobowola youma. Pamene mtheradi kubala mphamvu limatuluka 600 kPa-900 kPa, m'pofunika kugwiritsa ntchito kubowola katiriji kudula mphete, koma n'zosatheka kutenga mitima, choncho m'pofunika kugwiritsa ntchito kawiri-pansi kuphwanya kachiwiri.

4. Kubowola mano: 30/50.22 mm mano chipolopolo ndi 4S bullet mano otsogolera mano amagwiritsidwa ntchito kubowolera m'nyengo yolimba, yomwe imathandizira kuphwanya, kuchepetsa kusagwira kuboola, komanso kuchepetsa kutayika.
