- Rotational Torque:895N.m
- Feed stroke:1600mm
- Drilling Angle:0-90°
Introduction
HFU-3A full hydraulic tunnel drilling rig is mainly used in coal, geology, metallurgy, engineering and other industries, and is used for large-diameter gas pumping boreholes, water injection holes and large-diameter horizontal drilling in mines, tunnels, coal mines, and surface engineering. It can meet the requirements of large-diameter cone drilling, large-diameter cemented carbide drilling and percussion rotary drilling.
Features
-
- 1 Split arrangement, small size, light weight, easy relocation, flexible operation.
- 2 The power unit uses an explosion-proof motor and control system to drive the hydraulic pump, and the motor drives the spindle rotation and the cylinder chain speed mechanism to realize the feed and rotation functions of the power head.
- 3 The hydraulic chuck fully meets the clamping shackle and power-off protection functions of the drill pipe.
- 4 The mast slip and telescopic function is convenient for the mast to be close to the foundation when drilling, and to enhance the stability of the work.
- 5 The swing arm and mast swing up and down, suitable for multi-angle hole opening needs.
- 6 The power head spindle has a wide speed range and a large rotary torque.
