Pnuematic Drilling Rigs for Mining Using

MQT - 120/2.3 Pneumatic jumbolter

Application:

MQT-120/2.3 Pneumatic jumbolter are widely used in rock hardness acuities ≤ F10 roadway, especially adapt to the coal roadway's bolting work, can drill roof bolt hole, and drilling anchor hole, still can mix and install the resin cartridge anchor rod and anchor rope, without any other equipments, can be tighten the bolt and nut suitably at once, achieve initial anchor pre-stressing force requirements.

Characteristics:

- Small in size, light weight, simple manipulation, easy maintenance.

- Gear type pneumatic motor and stable running, high reliability.

- New glass reinforced plastic gas leg design, high reliability, long service life.
