ZYJ-400/130 150m Flameproofed portable coal seam gas Bracket Hydraulic Rotary Drilling Rig
ZYJ-400/130 Trestle hydraulic rotary drilling rig for caving hole and grouting hole
ZYJ-400/130-trestle hydraulic rotary drilling rig is applied to drilling of caving blast holes, drain holes, gas drainage hole, grouting hole, geological exploration holes and other projects holes
The drilling rig consists 4 part: drilling part, hydraulic power pack, operation panel, post.
Very good to be used in the tunnel or roadway, because the post will press against the roof and floor to stabilize the drilling rig.
The drilling part can move up and down along the post to drill in different height.
The height of the post can be optional according the height of the roadway.
It can also attached to the side of the road header to save space.
