overview

Product Introduction

HFU-4A+ full hydraulic tunnel drilling rig is mainly used in coal, geology, metallurgy, engineering and other industries, and is used for large-diameter gas drainage drilling, water injection holes and large-diameter horizontal drilling in surface engineering in mines, tunnels, and coal mines. construction. It can meet the requirements of large-diameter cone drilling, large-diameter carbide drilling and impact rotary drilling.

Technical characteristics   

1. Split layout, small size, light weight, easy to move and flexible operation. 

2. The power unit uses an explosion-proof motor and control system to drive the hydraulic pump, and the motor drives the main shaft to rotate and the cylinder chain double-speed mechanism to realize the feed and rotation of the power head.

3. The hydraulic chuck fully meets the drill pipe clamping, shackle, and power-off protection functions.

4. The mast sliding and telescopic function makes it convenient for the mast to be close to the foundation when drilling to enhance the stability of the work.

5. The up and down swing of the swing arm and the mast is suitable for the needs of opening holes at multiple angles.

6. The power head spindle speed range is wide, and the rotating torque is large.
