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.
