Pneumatic Anchor Drilling Rig

The pneumatic anchor drilling rig is a highly efficient drilling device powered by compressed air, specifically designed for support operations in coal mine roadways and rock formations of medium hardness. It is capable of drilling anchor bolt and cable holes, as well as mixing, installing, and fastening resin cartridge anchor bolts. With this equipment, anchor bolt installation and initial pre-tightening can be completed in one step without the need for additional tools.

Main Features of the Pneumatic Anchor Drilling Rig

Compact structure and light weight, easy to carry and operate, suitable for work in confined spaces.
Equipped with a high-performance pneumatic motor and smooth gear transmission, offering strong power output, quiet operation, and intrinsic safety against explosions.
High torque and fast rotation speed satisfy the requirements of efficient drilling and rapid installation.
Simple daily maintenance, low failure rate, and outstanding durability, making it suitable for long-term continuous operation.

Application Fields

The pneumatic anchor drilling rig is widely used in coal mine roadways, tunnel support, and anchor bolt/cable construction in rock roadways. It is especially suitable for underground environments with high explosion-proof requirements and limited working space, effectively improving the efficiency and safety of anchor bolt installation.
