Palu DTH Tekanan Udara Sedheng-Rendah
BRIA,BR2A lanBR3Seri DTH Hammers dirancang kanggo operate kanthi efisien ing tekanan udara sing kurang lan tekanan udara medium, nggunakake bit seri BR.
Fitur utama minangka nderek:
1. Tekanan udara operasi antara 0.7Mpa lan 1.75Mpa.
2. Palu tanpa katup.
3. Struktur prasaja, gampang kanggo ngumpul lan disassemble, umur dawa.
4. Frekuensi impact sing luwih dhuwur lan kacepetan pengeboran luwih cepet.
5. konsumsi udhara murah lan konsumsi lenga murah.A bolongan bisa dilatih ing katup mriksa kanggo nyedhiyani cuttings discharge luwih efisien.
6. Utamané cocok kanggo quarrying.
