1.General description :
MGJ-50LZ crawler drilling rig for anchoring and jet-grouting and
earth auger drilling, is a type of integration of rotary crawler,
mud pump, operation platform based on original MGJ-50 drilling rig
for anchoring and jet-grouting for anchoring bar, consolidating and
strengthening engineering and all other engineering geological
drilling.
The drilling machine is mainly used for soil, rock bolt,
embankment, dam foundation, retaining wall reinforcement, blasting
hole drilling and high pressure jet grouting hole construction.
2. Features:
- The rig is mechanical power, hydraulic feeding drilling rig,
drilling diameter in 110 ~ 130mm (up to 180mm), drilling depth of
60m, can be drilled at any angle between vertical and horizontal
hole.
- For the distance is up to 2300mm, use the 2m long drill pipe.
Otherwise 1500mm (short mast type), 1100mm (ultra short mast type)
optional.
- Using the rotary and percussive rotary drilling method, high
drilling efficiency.
- The support cylinder, easy adjustment of the mast of drilling
angle.
- By rotating the crawler, work platform can be ± 90 ° rotation,
suitable for horizontal drilling shift.
