Product Details

Scope of application:

MQTB-70/1.7 pneumatic leg type anchor bolt drilling rig is based on the actual working environment of coal mine underground, in order to reduce the labor intensity of workers and improve work efficiency, the bolt support tool developed on the basis of the original pneumatic hand-held drilling rig . The machine has the characteristics of small size, light weight, easy operation, stable operation and safe use. The machine has more torque and power than the pneumatic hand-held drilling rig, so that it can drill holes in the hard working surface; it can withstand the weight of the legs and overcome the anti-torque auxiliary propulsion, which is more suitable for the high position and shoulder of the roadway. Drilling, mixing and installation.

Pneumatic Roofbolter Drill Features:

The motor and air leg are the key components of the machine, with detailed drawings for your tasting:

1. Imported original Swedish SKF bearing, the leading brand in the bearing industry, effectively guarantees the long-term smooth operation of the whole machine;

2, gear type air motor, the motor can be stabilized at the set point when starting, stable operation and high reliability;

3. Double exhaust and new sealing structure ensure the fast and smooth lifting of the legs.
